Full Breakdown
Section 8-1-12 of the Municipal Code adopts the 2025 California Building Code, California Residential Code, California Green Building Standards Code, the 2024 International Property Maintenance Code, the California Electrical, Plumbing and Mechanical Codes, the International Swimming Pool and Spa Code, the California Administrative Code, the California Wildland-Urban Interface Code and the California Energy Code, all as amended locally, to govern erecting, constructing, enlarging, altering, repairing, moving, converting, demolishing and maintaining buildings and structures in the city. Section 8-1-13 amends Chapter 1's Section 105.2, 'Work Exempt from Permit,' revising Items 2 and 9 and removing Item 4, so anything not on that exempt list needs a building permit.
The same section adds Section 105.3.2.1, expiring an unpermitted application filed after a code enforcement notice of violation in 60 days absent a Building Official-approved extension, and amends Section 105.5 so a permit expires unless work begins within 12 months, with the Building Official able to grant extensions of up to 180 days each on written request showing justifiable cause. New Section 105.8 requires job sites to stay clean during remodeling, with building materials stacked in the rear yard or inside the construction perimeter except for up to 60 days in the front yard, and new Section 105.9 requires a reconstruction valued at 75 percent or more of the building's current value to meet full new-construction standards.
Section 8-1-2 makes unlawful construction, alteration or use contrary to the division a misdemeanor, with each day of violation a separate offense, punishable by up to a $500 fine, six months in county jail, or both, enforced by the Building Official and code enforcement staff within Community Development.
