New California Building Standards Code Changes Take Effect on January 1, 2020

Author: Department of Planning and Building
Date: 11/13/2019 3:34:19 PM

Beginning January 1, 2020, Planning and Building is required by state law to enforce the updated building codes. Learn more by attending a workshop on Tuesday, December 10, 2019.


Every three years, the State of California adopts new building codes (known collectively as the California Building Standards Code) to establish uniform standards for the construction and maintenance of buildings, electrical systems, plumbing systems, mechanical systems, and fire and life safety systems.

Beginning January 1, 2020, the County of San Luis Obispo Department of Planning and Building is required by state law to enforce the 2019 Edition of California Building Standards Codes (also known as Title 24 of the California Codes of Regulations).

All architects, engineers, designers, developers, owners and contractors are expected to be familiar with the updated codes. County Planning and Building, as required by state law, cannot approve projects that do not comply with the codes in effect at the time of plan submittal.
