Administration
The purpose of this chapter is to promote public safety and welfare by
reducing the risk of death or injury that may result from the effects of earthquakes on
unreinforced masonry buildings. Such buildings have been widely recognized for
sustaining life -hazardous damage, including partial or complete collapse during moderate
to strong earthquakes.
The provisions of this chapter are intended as minimum standards for
structural seismic resistance established primarily to reduce the risk of life loss or injury.
Compliance with these standards will not necessarily prevent loss of life or injury or
prevent earthquake damage to rehabilitated buildings. This chapter does not require
alteration of existing electrical, plumbing, mechanical or fire safety systems unless they
constitute a hazard to life or property.
