OVERVIEW
On February 11, 2026 (07), the Board of Supervisors took action to further consider and adopt
the Ordinances on March 4, 2026.
National building codes were developed in response to natural disasters, such as fires and
earthquakes. Advancements in building sciences and construction engineering have allowed
codes to evolve beyond simply reducing risks. Today’s codes establish minimum standards to
ensure homes and buildings are designed and constructed to protect public health, safety,
community welfare, and built to be more sustainable. Planning & Development Services (PDS)
helps establish, use, and enforce up-to-date building codes through the review of proposed plans,
issuance of building permits, and onsite construction inspections. These ongoing efforts,
including regular code updates, enhance building resiliency and welfare, and maintain a culture
of preparedness.
The California Building Standards Code (State Model Code) aims to ensure public health, safety,
and general welfare through provisions that address structural strength and stability, emergency
egress, fire prevention, electrical hazards, sanitation, air and water quality, energy efficiency,
accessibility, and the sustainability of buildings and structures. Structures designed and built to
these standards are more likely to maintain their structural integrity in the event of a disaster.
This provides building occupants with sufficient time to escape, ensures the safety of emergency
responders, and protects their lives.
Every three years, the State of California (State) updates the State Model Code. The 2025 edition
of the State Model Code was published on July 1, 2025, and is available for adoption as of
January 1, 2026. State law allows local governments to make more restrictive additions,
modifications, and deletions through local amendments to the State Model Code when the
changes are reasonably necessary due to local climatic, geological, and topographical conditions.
To ensure statewide public health and safety, the State Model Code prohibits local modifications
from being less restrictive than the baseline requirements contained in the codes. With each new
edition of the State Model Code, State law also allows local jurisdictions to readopt any existing
local amendments to be carried into the triennial code update. Once adopted, the collection of
State Model Codes and local amendments is collectively known as the County Building Code.
The 2025 State Model Code update makes significant advancements in energy efficiency and
building sustainability, aligning with the County’s Regional Decarbonization Framework and the
2024 Climate Action Plan (CAP). The CAP directs the County to expand access to programs and
services that will increase energy efficiency, energy resiliency, and electrification in the
unincorporated area. To implement the CAP, today’s request includes updates to the existing
