City Manager Approval: ______________
TOPIC: ACCESSORY DWELLING UNIT REGULATIONS
SUBJECT: AN ORDINANCE AMENDING TITLE 1 (GENERAL PROVISIONS), TITLE 4 (FIRE),
TITLE 12 (BUILDING REGULATIONS), AND TITLE 14 (ZONING ORDINANCE) OF THE
SAN RAFAEL MUNICIPAL CODE RELATED TO REGULATIONS FOR ACCESSORY
DWELLING UNITS, AND REPORT ISSUED PURSUANT TO GOVERNMENT CODE §
65858(d).
RECOMMENDATIONS:
Pass to print an Ordinance of the City of San Rafael Amending Title 1 (General Provisions), Title 4 (Fire),
Title 12 (Building Regulations), and Title 14 (Zoning Ordinance) of the San Rafael Municipal Code
Related to Regulations for Accessory Dwelling Units.
BACKGROUND:
This ordinance would establish local regulations consistent with changes in state law regarding
Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs). The State Legislature
has been modifying state law (California Government Code Section 65852.150 et seq.) governing ADUs
and JADUs to reduce barriers, streamline the approval process, and expand production throughout
California. The proposed ordinance complies with state law and would replace current San Rafael
Municipal Code ADU regulations, which do not comply with state law and are considered null and void.
In order to further study regulations for ADUs and JADUs, on October 18, 2021, the City Council
introduced and adopted an interim urgency ordinance (Ordinance No. 2001), which established a
temporary, forty-five (45) day moratorium on the issuance of accessory dwelling unit and junior accessory
dwelling unit permits on properties located on certain narrow hillside streets within the City of San Rafael,
and declared the urgency thereof. Pursuant to California Government Code §65858(a), interim
ordinances remain in effect for 45 days from the date of adoption but may be extended following notice
and a public hearing. Under California Government Code § 65858(d), the City Council is required to issue
a written report ten days prior to expiration of the interim ordinance, describing the measures taken to
alleviate the condition which led to the ordinance’s adoption. Ordinance No. 2001 is set to expire
December 2, 2021. Issuance of this report satisfies the requirements of California Government Code
§65858(d).
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 2
ANALYSIS:
When enacting changes to the laws regulating ADUs and JADUs, the California Legislature has found
and declared, among other things, that ADUs and JADUs provide additional rental housing and can add
needed housing units in single and multifamily zoned areas, and thus play an essential role in addressing
California’s housing needs. ADUs and JADUs increase the forms of housing in a community and can
offer more affordably priced housing options for extended family members, friends, students, older adults,
caregivers, people with disabilities, and others.
On March 23, 2021, the Planning Commission held a duly-noticed public hearing (Case No: ZO21-001),
received all public comment, and unanimously recommended City Council adoption of an ordinance
establishing ADU and JADU regulations. The attached ordinance includes the regulations reviewed and
recommended by the Planning Commission, except that the ordinance does not include a prohibition on
ADUs or JADUs in hillside areas, which is discussed later in this report.
The Ordinance regulates ADUs and JADUs as follows:
Size of Unit (Floor Area).
• ADUs would need to have a minimum size of 150 square feet (known as an efficiency unit);
• Attached ADUs would have a maximum floor area of 1,000 square feet or 50% of the existing
residence, whichever is less;
• Detached ADUs would have a maximum floor area of 1,000 square feet;
• There is no maximum size limit for ADUs that involve the conversion of an existing detached
structure;
• There is no maximum size limit for an ADU created from internal conversion of portions of an
existing primary residence;
• JADUs may be no less than 150 square feet and no more than 500 square feet.
Required Setbacks.
• Maximum rear and side yard setbacks of a new or expanded ADU are 4 feet;
• No additional setbacks are required for internal conversions;
• Front yard setback will be the same as required for the primary residence.
Maximum Height:
• Up to 16 feet high if within 4 feet of the rear or side yard;
• Height limited in the Eichler-Alliance overlay district may not exceed a height of 17 feet;
• Accessory dwelling units complying with the development standards established for the primary
residence are subject to the same height limit established by the district governing the property.
Location Restrictions.
The regulations that the Planning Commission reviewed included a prohibition of ADUs and JADUs on
hillside properties solely accessed from a list of prohibited streets. The prohibition was included due to
concerns from the San Rafael Fire Department that in some instances, narrow and steep roadways
combined with high levels of on-street parking on those streets, can restrict fire truck access and result
in inadequate fire response access during a fire emergency. On October 18, 2021, the City Council
adopted an interim urgency ordinance (“moratorium”) to pause the issuance of ADU’s/JADUs on
properties that front on those streets included in the “list of prohibited streets” and directed staff to return
with an update report and a proposed ADU Ordinance that would establish regulations for ADU/JADUs
within the City. After the City Council hearing, staff further studied the issue, reviewed state law, and
determined a prohibition was not justified in view of the following circumstances:
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 3
• Implementation and enforcement of the City’s new parking box program, which will reduce on-
street parking to specific marked areas ensuring adequate fire truck access on narrow hillside
streets; and
• State prohibition on using certain ADUs and JADUs as short-term rentals, and the requirements
in the City’s Short-Term Rental Program for all other ADUs and JADUs.
Further discussion and analysis of the initial prohibition proposal is presented below.
Properties Solely Accessed by Certain Hillside Streets
The State of California Housing and Community Development Department (HCD) is the lead state agency
overseeing administration of state development regulations for housing and provides guidelines for ADUs
and JADUs on its website (California State ADU Guidelines). HCD requires local jurisdictions find
solutions to enable housing when a locally identified condition presents an issue to implementing state
law. Once an ADU regulation or program is adopted by a local jurisdiction, a copy must be provided to
HCD, which has 60 days to evaluate and respond, notifying the jurisdiction if the new regulation or
program is not consistent with state law. If HCD finds the ordinance to be inconsistent with state law, the
local jurisdiction must cure those inconsistencies or face possible enforcement action by the California
Attorney General.
As noted above, the proposed ordinance does not include a prohibition on ADUs or JADUs in hillside
areas reviewed and approved by the Planning Commission in March. After the Planning Commission
made its recommendation and prior to finalizing the draft ordinance, staff continued to study the fire safety
access concerns on the identified hillside streets and the proposed prohibition of ADUs and JADUs on
the list of prohibited streets. Staff also reviewed the allowances that state law provides to local
jurisdictions to prohibit ADUs and JADUs for public health and safety reasons.
The City Council adopted the interim urgency ordinance on October 18, 2021 after staff determined
further analysis was required to determine whether the proposed prohibition of ADUs and JADUs on
narrow, hilly streets, or other regulations would be consistent with current state housing laws.
The City’s Measures During the Pendency of the Moratorium Enacted October 18, 2021
Since enacting the moratorium, the City has continued the process of studying the issues related to fire
safety access in hillside areas and the allowances provided in state law for local jurisdictions to enact
prohibitions on ADUs and JADUs. Staff met internally two times to discuss the Fire Department’s
concerns, review the regulations in other local communities, and evaluate how the City’s recently adopted
Parking Box program may alleviate the concerns for fire vehicle access in hillside areas. Additionally, on
October 28, 2021, City staff discussed the access concerns and allowances under state law with
representatives of HCD who inquired about which solutions the City had sought to ameliorate the
condition of parking on the identified streets.
The prohibition reviewed by the Planning Commission was proposed by staff as a means to ensure
adequate fire truck access during emergencies on narrow hillside streets where on-street parking has a
tendency to constrict vehicle access. However, the Fire Department has confirmed that this on-street
parking problem has been addressed by the City’s adoption of its parking box program, which eliminates
on-street parking in hillside areas where roadway widths are not wide enough to safely allow fire trucks
to pass by parked vehicles. The Parking Box program is currently being implemented and with proper
enforcement should ensure proper access.
Additionally, under the ordinance, an ADU proposed outside of ½ mile walking distance to public transit
must provide a parking space on the property, preventing additional demand for on-street parking. ADUs
and JADUs used as short-term rentals must abide by the City’s Short-Term Rental Program, which
requires among other requirements that parking is provided on the property. Staff is currently reviewing
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 4
the Short-Term Parking Program and plans to bring a report on the program to the City Council in the
first quarter of 2022.
For the reasons noted above, staff has concluded that the prohibition of ADUs and JADUs on the list of
prohibited streets that was reviewed and approved by the Planning Commission is not required.
Therefore, staff has not included the prohibition in the proposed ordinance before the City Council. Staff
finds that the proposed ordinance will bring the City’s ADU regulations into conformity with state law and
recommends its approval. Once adopted, staff will forward the ordinance to HCD for confirmation of its
consistency with state law.
Conclusion
Significant steps have been taken to study the issue of permanent ADU/JADU regulations since the
Council’s adoption of the moratorium on October 18, 2021, and thus alleviate the condition giving rise to
the adoption of the moratorium ordinance.
ENVIRONMENTAL DETERMINATION:
Consideration and adoption of the ordinance by the City of San Rafael City Council is statutorily exempt
from the provisions of the California Environmental Quality Act (CEQA) pursuant to Public Resource
Code 21080.17 providing that CEQA does not apply to the adoption of an ordinance implementing the
provisions of Section 65852.1 (Accessory Dwelling Units) or Section 65852.2 (Junior Accessory Dwelling
Units) of the California State Government Code.

district that allows the development of single-family or multifamily dwelling
residential uses. ADUs may be permitted on any lot with a legal nonconforming
residential structure. The following are the four types of Accessory Dwelling
Units permitted within the City:
Attached ADU. An Accessory Dwelling Unit that shares at least one
common wall with an existing primary dwelling and is not fully contained
within the existing space of the primary dwelling or an Accessory Structure.
An attached ADU also includes an ADU which is proposed to be constructed
concurrently with a proposed primary dwelling unit and which is attached to
or constructed within said primary dwelling unit.
Detached ADU. An Accessory Dwelling Unit that does not share a common
wall with the existing or proposed primary dwelling and is not fully contained
within the existing space of an accessory structure.
Page-11
Internal ADU. An Accessory Dwelling Unit that is fully contained within the
existing space of an existing primary dwelling or contained within the existing
space of an existing Accessory Structure.

REPORT TO PLANNING COMMISSION
SUBJECT: Purposed Amendments to the San Rafael Municipal Code to Comply with State
Accessory Dwelling Unit Requirements
EXECUTIVE SUMMARY
Over the past several years the State has adopted changes to regulations related to Accessory Dwelling
Units (ADUs) and Junior Accessory Dwelling Units (JADUs). These changes are intended to simplify the
review process by requiring that ADUs/JADUs be considered by local municipalities through a ministerial
review process within a certain time frame. In addition, the State regulations placed a limit on development
standards that a municipality is able to impose on proposed ADUs/JADUs.
Staff has prepared a Draft Ordinance (Exhibit B) that incorporates the State requirements and includes
City specific standards where allowed. Because ADUs and JADUs contribute to the rental housing stock
and contribute toward the City’s regional housing obligation, the ordinance will continue to encourage the
development of ADUs and JADUs. However, as proposed, the Draft Ordinance would prohibit
ADUs/JADUs on certain streets due to access difficulties. Exhibit D of this report includes a map and a
list of those streets where ADUs/JADUs would be prohibited. It is possible that this list may be updated
from time to time to reflect changing conditions.
RECOMMENDATION
It is recommended that the Planning Commission accept public comment, discuss and provide feedback
regarding proposed changes to ADU ordinance and adopt a resolution recommending approval of the
proposed ADU ordinance and associated amendments.
BACKGROUND
Rules governing Accessory Dwelling Units (ADUs) have been continually evolving over the years. These
changes are meant to make it easier to accommodate the development of ADUs to increase housing units
and address California’s housing need. Changes in 2003 required that ADU’s be a ministerial approval
and the rules have kept changing since then to reduce barriers for applicants.
Until 2017, the City of San Rafael had regulated the development of accessory dwelling units through the
City’s second unit ordinance set forth under San Rafael Municipal Code (SRMC) Section 14.16.285) and
junior accessory dwelling units (or junior second units) through SRMC Section 14.16.286. Under the prior
municipal code, Second Units were defined as any additional, separate dwelling unit meeting defined
standards, as specified in Section 14.16.285 and located on the same lot as a single-family dwelling within
a residential district. The prior code did not differentiate between conversion or new addition; Junior
Second Units were defined as an additional, independent living unit created through the conversion of an
existing bedroom in a single-family dwelling subject to defined standards. Junior second units are
distinguished from second dwelling units in that they: (a) must include the conversion of an existing
SAN RAFAEL
THE CITY WITH A MISSION
REPORT TO PLANNING COMMISSION - Case No: ZO21-001 Page 2
bedroom(s) within a single-family dwelling (no new or additional building area); (b) are smaller in size
(maximum size of five hundred (500) square feet); (c) contain either independent or shared bathroom
facilities; and (d) are subject to unique standards that are not applicable to second dwelling units.. San
Rafael’s current ordinances include development standards (such as height, setback, and unit size),
parking requirements, and permit requirements (including discretionary review requirements).
On January 1, 2017, new State legislation through adoption of SB1069, AB 2406 and AB2299 became
effective and made SRMC sections 14.16.285 - Second dwelling units and 14.16.286- Junior Second Units
null and void as these sections do not comply with State regulations. SB1069, AB 2406 and AB2299
brought in some drastic changes. Here are a few of the main changes that came at that time:
• All ADU applications that meet the established standards are go through a ministerial permit
process
• Limits how much parking a local jurisdiction can required based on proximity to transit and other
factors. Allowed local jurisdictions to require replacement of parking spaces lost through
conversion of carport or garage.
• Allowed local agency to require a new or separate utility connection directly between the accessory
dwelling unit and the utility, but fees shall be proportional to the burden created by the ADU. Units
contained within an existing structure shall not be required to install new utility connections.
• Fire Sprinklers are not required for an ADU if they are not required for the primary residence.
Staff began developing a new ADU ordinance to comply with the new state laws but things were put on
hold when we learned of the new large scale changes that were coming in 2020.
On January 1, 2020, the anticipated new laws became effective. Some of the regulations from 2017
remained however some of those changes were broadened to further restrict local limits. Below are
some of the major changes that came with the most recent legislation:
• Size Limits. If a local agency imposes size limitation by ordinance, the allowable maximum size of
an ADU cannot be less than 850 square feet, or 1,000 square feet if the ADU contains more than
one bedroom and requires approval of a permit to build an ADU of up to 800 square feet
((Government Code § 65852.2(c)(2)(B) & (C)).
• Owner Occupancy Requirements. All owner-occupancy requirements have been eliminated for
ADUs approved between January 1, 2020 and January 1, 2025 ((Government Code § 65852.2.
(a)(6)).
• Minimum Lot Size. No minimum lot size standards can be required (Government Code §
65852.2(a)(1)(B)(i)).
• Replacement Parking. Replacement off-street parking cannot be required for an ADU created
through the conversion of a garage, carport or covered parking structure, (Government Code
§65852.2(a)(1)(D)(xi)).
• Review Timeframe. A completed ADU application must be reviewed within 60 days (Government
Code § 65852.2(a)(3) and (b)).
• Fees. ADUs up to 750 square feet are exempt from impact fees (Government Code Section
65852.2, Subdivision (f)(3)); ADUs that are 750 square feet or larger may be charged impact fees
but only such fees that are proportional in size (by square foot) to those for the primary dwelling
unit (Government Code § 65852.2(f)(3)).
• JADU Space. A permitted JADU does not need to include an existing bedroom (as had been
established by the City of San Rafael). JADUs can now be constructed within the walls of the
proposed or existing single-family residence and an interior entry into the single-family residence
is no longer required. (Gov. Code § 65852.22 (a)(4); Former Government Code §
65852.22(a)(5)).
REPORT TO PLANNING COMMISSION - Case No: ZO21-001 Page 3
• Code Enforcement. Property owners can request a delay in Code enforcement against an ADU
for five (5) years to allow the owner to correct the violation, so long as the violation is not a health
and safety issue. (Government Code § 65852.2(n); Health and Safety Code § 17980.12).
Staff has prepared a comparison table (Attachment C) that shows the City’s Second Unit requirements
compared to changes made by recent state legislation and how the proposed ordinance would address
each development standard. This report provides an overview of the difference between the new State
laws and the proposed changes to the SRMC sections that pertain to Accessory Dwelling Units (or Second
dwelling units and Junior second units as they are currently called in the code).
PROJECT DESCRIPTION & ANALYSIS
Because the City’s ADU ordinance no longer complies with state law, staff has prepared a draft
ordinance that would replace our existing regulations related to ADUs and JADUs (or Second dwelling
units and Junior second units as they are currently called in the code). In the Background Section,
above we discussed the primary standards that were necessary to comply with state law and therefore
cannot be modified. As such, the proposed Ordinance either incorporates those standards or refrains
from imposing limits as required by the State. As mentioned above, Exhibit C provides a side by side
comparison with an explanation of the City’s limitations imposed by State legislation.
City Specific Standards-This section will focus on four areas where City of San Rafael has discretion to
adopt specific standards through adoption of an ordinance:
• Size of Unit
• Required Setbacks
• Height Restrictions
• Location restrictions
Staff is proposing the following allowable City specific standards to be incorporated as part of the City of
San Rafael Accessory Dwelling Unit Ordinance.
A. Size of Unit
The state law increases the maximum size of the ADU that local jurisdictions must allow. State law
previously applied a unit size of 1,200 square feet. With adoption of an ordinance the City is able to
establish more strict unit size limits within the following parameters:
• The City must allow efficiency units. Efficiency units are units with a minimum floor area of 150
square feet.
• Unit sizes must be at least 850 square feet for a studio or 1 bedroom unit or 1,000 square feet for
ADUs with more than one bedroom.
• Conversion of an existing structure or portion of the existing primary residence to an ADU cannot
be subject to size limits.
• JADU size requirements can range between 150 square feet to 500 square feet.
The proposed ordinance provided a simplified approach by following the above guidelines and establishing
a maximum allowable floor area of 1,000 square feet for new attached or detached ADU. There is no size
limit to conversion of existing space as noted above. The following table shows the minimum and
maximum allowed based on type of ADU:
REPORT TO PLANNING COMMISSION - Case No: ZO21-001 Page 4
Attached Detached Internal Conversion Junior ADU
Minimum Floor
Area
150 square feet 150 square

150 square feet 150 square feet
Maximum Floor
Area
1,000 sq. ft. or 50% of the floor
area of an existing primary
dwelling unit, whichever is less
1,000
square feet
N/A 500 square feet
The above maximum size limits would create some consistency between attached and detached
ADUs. The City is not able to establish maximum unit sizes for ADU created from internal conversion
of existing space.
B. Required Setback
The maximum required rear and side yard setback for ADUs is 4 feet as this is established by state
law. State law is silent on front yard setback limitations. Staff is proposing that the front yard setback
of an ADU comply with the setback established for the primary residence.
All other accessory structures located between the front setback and the front wall of the house are
only allowed with a design review approval.
Proposed Setbacks for new construction ADUs
Front Same as primary dwelling
Side 4 Feet
Rear 4 Feet
Front Entry 10 Feet from any right-of-way
Reverse Corner Rear 20 feet of the street side yard shall have a 15 foot
setback
Decks, Balconies and Platforms greater than 12”
Rear or side yard shall have a 4 foot setback
C. Maximum Height
Pursuant to state law detached accessory dwelling units are allowed to be at least 16 feet high if it is
within 4 feet of the rear or side yard. Height increase of a detached accessory unit of no more than 1
foot when such increase results in an improved design. However, in no case shall an accessory dwelling
unit located in the Eichler-Alliance overlay district exceed 17 feet in height. Height increase of a detached
accessory unit of no more than 1 foot when such increase results in an improved design. Accessory
dwelling units that comply with the minimum development standards established for the primary
residence shall be subject to the same height limitations established by the district that governs the
property.
D. Location Restrictions
State law allows cities to prohibit ADUs/JADUs in certain locations due to public safety reasons. Staff has
identified certain streets that are difficult to access due to due to narrow travel lanes (<14'), excessive
turning radius, maneuvering difficulty, and/or lack of turnaround, as determined by the Fire Chief and the
Community Development Director. Therefore, staff is proposing that that the ordinance prohibit ADUs and
JADUs on those streets. The ordinance recognizes that the list will need to be updated form time to time
and obligates the Community Development Department to maintain and publish an updated list of those
streets where ADUs are prohibited and make this list available to the public. A draft list of challenged
hillside streets where ADUs would be prohibited is presented in Attachment D.
ENVIRONMENTAL DETERMINATION
This project qualifies for exemption from the provisions of the California Environmental Quality Act
(CEQA) Guidelines pursuant to Sections 15182(h) which states that the adoption of an ordinance
REPORT TO PLANNING COMMISSION - Case No: ZO21-001 Page 5
regarding second units in a single-family or multifamily residential zone qualifies for statutory exemption
under CEQA.
NEIGHBORHOOD MEETING / CORRESPONDENCE
Notice of hearing for the project was conducted in accordance with noticing requirements contained in
Chapter 29 of the Zoning Ordinance. A Notice of Public Hearing was published in the Marin IJ and
mailed to all to stakeholders, agencies and special interest groups on January 19, 2021. Those noticed
included, among others, all neighborhood associations, the Federation of San Rafael Neighborhoods,
and housing advocacy groups. The Draft Ordinance was posted on the City’s website where opportunity
for public comment was given. Most comments were favorable but we also received comments with
specific points that either need clarity or that expressed opposition to the draft ordinance as proposed.
The following is a summary of comments provided to date:
In Support:
• City needs this level of flexibility for property owners to help to increase the affordable rental housing
stock.
• Fast track approval processes and non-restrictive size limitations are very attractive.
• Support because City needs more housing.
In Opposition:
• Worries about lack of Parking/Traffic in general
• Feeling that we should be prioritizing the current city residence’s quality of life over the people who
do not live here yet and who need an "affordable" place to live. They expressed that they do not need
our local government to facilitate new low-rent housing by increasing housing density.
• Concerns on the height allowance, 16 Feet is too tall.
• Concerns over the restrictions on ADUs on certain narrow streets citing that the property owners on
their narrow street park responsibly and we should focus on enforcing the parking regulations rather
that taking away the ability to add an ADU at all. We should solve the issue of illegal parking rather
than prevent additional ADUs. (This person is in favor of the ADU ordinance overall but has issue
with this particular point in the ordinance.)
Items that need clarification:
• It would be useful to spell out what a variance is and what is the process and fees.
Response: The Variance process is spelled out in the SRMC Chapter 14.23. There is public hearing
process required for variance request and the process includes notification to neighboring property
owners. Fees would depend on the type of variance requested but generally range between $2508
to $3767.
• In the parking section: unclear what an architecturally/ historically significant district is and it is not
clear what “The accessory dwelling unit is part of the proposed or existing primary residence or an
accessory structure” means.
Response: This language was taken from the Government Code. There are no architecturally
significant districts within the City however, we do have three sites that have been deemed historic
districts: The Victorian Village (1623-27 Fifth Avenue), The French Quarter (901-911 Irwin Street),
and 1811-1817 Grand Avenue.
REPORT TO PLANNING COMMISSION - Case No: ZO21-001 Page 6
• Not clear on the distinction of a JADU vs. Internal Conversion ADU.is it just a difference of total
square footage? i.e. -- if less than 500, then qualifies as JADU, but if over 500 then classified as a
JADU?
Response: The primary difference is that a JADU is 500 square feet or less and may have internal
access.
OPTIONS
The Planning Commission has the following options to consider on this matter:
1. Adopt the Resolution recommending City Council Adoption of the proposed ordinance.
2. Adopt the Resolution recommending City Council Adoption of the proposed ordinance with
modifications.
3. Direct staff to return with more information.

installed on the ADU or on the primary
dwelling unit. ADUs that are constructed
within existing space, or as an addition to
existing homes, including detached
additions where an existing detached
building is converted from non-residential
to residential space, are not subject to the
Energy Code requirement to provide solar
panels.
panels are not specifically noted as
required or not required.
Fire Sprinklers Installation of fire sprinklers may not be
required in an ADU if sprinklers are not
required for the primary residence.
However, if the same primary dwelling
recently undergoes significant
remodeling and is now required to have
fire sprinklers, any ADU created after
that remodel must likewise install fire
sprinklers. (Gov. Code, §
65852.2(a)(1)(D)(xii) and (e)(3))
For ADUs created on lots with multifamily
residential structures, the entire
residential structure shall serve as the
“primary residence”. Therefore, if the
multifamily structure is served by fire
sprinklers, the ADU can be required to
install fire sprinklers.
No change to provisions in
Government Code 65852.2
No specific fire sprinkler standards
are listed in the ADU section of the
municipal code.
A JADU is not required to have
sprinklers unless it constitutes a
substantial remodel but there are a
few other requirements listed as fire
safety requirements.
Expansion An ADU within the existing or proposed
space of a single-family dwelling can be
expanded 150 square feet beyond the
physical dimensions of the structure but
shall be limited to accommodating ingress
and egress.
No change to provisions in
Government Code 65852.2
Expansion of a detached or
attached structure for an ADU is
subject to the same development
standards as an expansion for any
other use.

I have lived in San Ra fael for 12 years. When I first moved here, I could come and go from my home in Gerstle Park at just about any hour of the day
without being subjected to heavy vehicular traffic , on my way to or from the freeway. In the last few years, that has changed , even before SMART. I now
try to avoid going anywhere, if I can , except between 10 AM and 2 PM . If you could add an additional lane to each of the second and third street corridor
routes, then you would maintain the quality of life here . Of course, Increasing the downtown vehicular artery is impossible. Therefore , if you increase
housing density, there are two things that are guaranteed to happen : 1 . You will degrade the quality of life here because every one of us will hate having
the ingress and egress from our homes . 2 . People who have the financial means to move elsewhere will do so. 11 ived in Los Angeles for 26 years.
Transportation congestion is the main reason why I left. You do not have a responsibility to the people who do not live here yet and who need an
"affordable" place to live . We have rent control now; t his protects current residents . We do not need our local government to facilitate new low-rent
housing by increasing housing density. You have a responsibility to the people who live here now.

Thank you the your good work! T his is a good draft, with lots of Info! Question :
How would I know if my house is In an Eichler Alliance District?
Suggestion:
It would be useful to spell out what a variance is and what is the process and fees.
Thanks again!

Thank goodness. It's about time. We need more housing .
Draft ordinance makes sense although 16' height seems pretty tall . ls that to accommodate sleeping loft?
There are some streets in San Rafael like Union and Park that have virtually no available street parking as it is. I think a little more consideration should
be given to requiring parking, if that is allowable within the state f ramework. Half a mile from transit is silly. Marin public transit is worthless.

The draft seems clear. And appreciate that this draft ordinance makes it easier to develop an ADU and get an ADU approved . But I am not sure how the
current •state laws made our Accessory Dwelling Unit (ADU) ordinance ineffective• so am not sure how this draft addresses t ha t.

This seems straightforward and thorough . It sounds like it is expanded to encourage more development.
BTW I clicked the download bu tton and it opened the pdf in a new tab now titled "Benecia Municipal Code". Maybe you want to edit that link.
Great job
Paula

-Not clear on the distinction of a JADU vs. Internal Conversion ADU ... .is it just a difference of tota l square footage? le -if less than 500 , then qualifies
as JADU , bu t if over 500 then classified as ICADU?
-These parking requirement exclusions seem to be an Invitation for problems:
"No Parking shall be required for the following :
a) The accessory dwelling unit is located within one-half mile walking
distance of public transit."
-> it would seem that this will invite landlords to make units without parking, but rent to tenants who have cars, thus creating adverse impact on
congestion and parking overall. As an alternative , it would seem better to say that any ADU that does NOT have dedicate parking can NOT rent to a
tenant with a vehicle (thereby i ncentivizing the use of public transit or other alternative transportations means)
"b) The accessory dwelling unit is located within an architecturally and
historically significant historic district.•
-> Not clear on what districts meet this qualififlcatlon but the same alternative would seem to apply. "If no parking is provided , then can no rent to a
tenant with vehicle ."
c) The accessory dwelling unit is part of the proposed or existing primary
residence or an accessory structure.
-> what does this mean?

Fabulous! Bravo I This ordinance allows property owners the flexibility needed to increase the rental housing stock, particularly relatively affordable
housing , while allowing renters to experience San Rafael's diverse neighborhoods -something which increases quality of life for those renters ( and
some primary dwelling occupants! )and which promotes City unity across varied economic strata. Fast track approval processes and non restrictive size
I Imitations are very attractive and I expect this ordinance will be highly successful if there are enough property owners who see a benefit in constructing
an ADU on their property. For those who already do see a benefit and are excited to gel started , the San Rafael Planning Department has certainly
helped to make the process pain free and highly appealing. Congrats!

Restricting ADUs on roads less that 14' or where parking on streets blocks traffic is a punitive action against homeowners who may wish to develop an
ADU . If there is illegal parking congestion on roads (e .g . parking within 6' of center line , vehicles parked for more than 72 hours, etc) th ose infractions
should be enforced . In my neighborhood some residents use their garages and carports for storage and leave their vehicles on the narrow road for
extended periods of time. I have never seen a traffic patrol or tickets on illegally parked vehicles In many years in the hills of San Rafael. Individual
decisions to park illegally which have not been enforced by the city should not prevent those who legally park and own homes from adding more housing .
We should solve the issue of illegal parking rather than prevent additional ADUs .
