Section 19160 Of Article 4. Earthquake Hazardous Building Reconstruction From California Health And Safety Code >> Division 13. >> Part 3. >> Chapter 2. >> Article 4.
19160
. The Legislature finds and declares that:
(a) Because of the generally acknowledged fact that California
will experience moderate to severe earthquakes in the foreseeable
future, increased efforts to reduce earthquake hazards should be
encouraged and supported.
(b) Tens of thousands of buildings subject to severe earthquake
hazards continue to be a serious danger to the life and safety of
hundreds of thousands of Californians who live and work in them in
the event of an earthquake.
(c) Improvement of safety to life is the primary goal of building
reconstruction to reduce earthquake hazards.
(d) In order to make building reconstruction economically feasible
for, and to provide improvement of the safety of life in,
seismically hazardous buildings, building standards enacted by local
government for building reconstruction may differ from building
standards which govern new building construction.
(e) "Soft story" residential buildings are a subset of multistory
woodframe structures that may have inadequately braced lower stories
that may not be able to resist earthquake motion.
(f) Soft story residential buildings are an important component of
the state's housing stock and are in jeopardy of being lost in the
event of a major earthquake.
(g) Soft story residential buildings were responsible for 7,700 of
the 16,000 housing units rendered uninhabitable by the Loma Prieta
earthquake and over 34,000 of the housing units rendered
uninhabitable by the Northridge earthquake.
(h) During an earthquake, soft story residential buildings may
create dangerous conditions as illustrated in the Northridge Meadows
apartment failure that claimed the lives of 16 residents.
(i) The collapse of soft story residential buildings can ignite
fires that threaten trapped occupants and neighboring buildings and
complicates emergency response.
(j) The Association of Bay Area Governments (ABAG) estimates that
soft story residential buildings will be responsible for 66 percent
of the uninhabitable housing following an event on the Hayward fault.
(k) The failure of soft story residential buildings is estimated
by ABAG to be the source of a disproportionate share of the public
shelter population because they tend to be occupied by the very poor,
the very old, and the very young.
(l) The Seismic Safety Commission has recommended that legislation
be enacted to require state and local building code enforcement
agencies to identify potentially hazardous buildings and to adopt
mandatory mitigation programs that will significantly reduce
unacceptable hazards in buildings by 2020.
(m) The current nationally recognized model code relating to the
retrofit of existing buildings is Appendix Chapter A4 of the
International Existing Building Code. However, it is not the intent
of the Legislature, if other model codes relating to the retrofit of
existing buildings are developed, to limit the California Building
Standards Commission or a local government, pursuant to Section
19162, to adopting a particular model code.
(n) Therefore, it is the intent of the Legislature to encourage
cities and counties to address the seismic safety of soft story
residential buildings and encourage local governments to initiate
efforts to reduce the seismic risk in vulnerable soft story
residential buildings.
