SECTION THREE:
Section 23 12.035 R332 is added to the City Building Code to read as follows
SEC.23.12.035.R332 SOLAR-AND ELECTRIC VEHICLE-READY BUILDINGS
Section R332 is added to the California Residential Code to read
Sec. R332 Solar- and electric vehicle-ready buildings. Solar- and electric vehicle-ready
construction shall be provided as specified in Section 23.12.035.3112 of the City Building
Code.
SECTION FOUR:
As required by Health and Safety Code section 17958 7 the City Council makes express findings
that amendments to the California Building Standards Code are necessary for the protection of the
public health, safety and welfare due to certain climatic, topographic or geological conditions
City Code is being amended to require new single family development to include an electric panel
large enough for future photovoltaic and / or electric vehicle charging system, installation of conduit
for future photovoltaic and electric vehicle charging system and reserving south facing roof for future
solar
The City finds and declares that adding the referenced code changes is necessary due to local
climatic conditions As a result of high summer ambient temperatures and periods of heat waves,
average load demand and peak load demand of energy used in San Diego County is an important
factor concerning public safety and adverse economic impacts of power outages or reductions
Facilitating the installation of an electric panel large enough for future photovoltaic and / or electric
vehicle charging system, installation of conduit for future photovoltaic and electric vehicle charging
system, and reserving south facing roof for future solar will have local and regional benefits in the
reduction of total and peak energy use and greenhouse gas emissions
SECTION FIVE:
The project is exempt from CEQA pursuant to the State CEQA Guidelines Section 15061(b)(3)
because it can be seen with certainty that there is no possibility that this project may have a
significant effect on the environment. The proposed draft ordinance changes, should they be
approved, would require increased energy efficiency in new building construction Staff has reviewed
the changes and find no risk of environmental impact.
