2019 California Building Codes Go into Effect January 1, 2020
The California Building Standards Commission updates the State building codes every three years. The 2019 codes were published on July 1, 2019 and will become applicable to all building permit applications submitted on or after January 1, 2020. Building permit applications submitted on or prior to 4pm on December 23, 2019 are under the 2016 codes. 


The Building Division consists of three primary sections - Plan Check, Inspection, and Permit Administration.


The Plan Check section performs residential and commercial plan checks for fire and life-safety, structural, electrical, mechanical, plumbing, Title-24 energy, Title-24 disabled access, and pertinent municipal code and state regulations governing the design and construction of buildings and other structures.

The Inspection section inspects buildings during construction for building, electrical, plumbing, and mechanical code compliance and responds to complaints concerning alleged building code violations.

The Permit Administration section is responsible for all aspects of the building permit process, including processing and routing of applications and revisions, issuing permits, maintaining applied, issued, expired and canceled permits, and for providing timely reporting of permit information to the public.
