State law that overrides local zoning here
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.
Gov. Code 66310 et seq.
State ADU law preempts local zoning that would preclude a conforming ADU/JADU.
Applies when: project includes an ADU or JADU
Gov. Code 65915
State Density Bonus Law concessions/waivers override local development standards.
Applies when: project requests a density bonus
Gov. Code 65852.21 / 66411.7
SB 9 urban lot split / two-unit ministerial approval preempts conflicting local standards.
Applies when: project is an SB 9 lot split or two-unit development
Ventura enforces 2025 CBC, T24 Pt 2 based on 2024 IBC, the edition adopted statewide in California, amended locally in 3 disciplines.
Does Ventura amend the California code?
Yes: building, zoning, coastal.
Where do I confirm the code edition for a Ventura permit?
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.
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.
