Mapped hazard and district overlays stack on top of the adopted code. These are the overlays recorded for Los Angeles County. They apply by parcel, not jurisdiction-wide, so confirm the parcel before assuming one is in play. Check CAL FIRE's fire hazard severity viewer and FEMA's flood map service.
When one of these applies, the state statute governs over a conflicting local standard. This is the most common reason a local rule someone quotes you turns out not to be enforceable against a project.

Applies when: project includes an ADU or JADU
State Density Bonus Law concessions/waivers override local development standards.
Applies when: project requests a density bonus
SB 9 urban lot split / two-unit ministerial approval preempts conflicting local standards.

West Hollywood enforces 2025 CBC, T24 Pt 2 based on 2024 IBC, the edition adopted statewide in California, amended locally in 2 disciplines (Ord. 25-26).
Yes: building, zoning. For building, the rule is: local text supersedes the state code.
With the city building department that will review the permit. Adoption ordinances are amended on a local schedule, and a set submitted days apart can fall under different editions during a changeover.
Knowing the adopted edition is the easy half. Architechtura reads your drawings, resolves which of these provisions actually apply to the project, and returns the corrections a plan checker would write up, each one cited to the section it came from.
Your first check is free, no card required.
Compiled from published state and municipal adoption ordinances. Local governments amend their codes on their own schedule, and a pending ordinance can change what applies to your permit. Confirm the governing edition with the building department before you submit. This page is reference information, not a code determination.
