Summary

Antioch enforces the 2022 California Green Building Standards Code (CALGreen) by reference, the statewide mandatory-measures code that applies to new building permits citywide. There's no separate local green-building chapter beyond the adoption clause; violating CALGreen is treated like violating any other code the city has adopted by reference, ordinarily a misdemeanor under the general penalty section.

The 2022 California Green Building Standards Code, published by the State of California, Department of Housing and Community Development, Division of Codes and Standards, as adopted and amended by the California Building Standards Commission in the California Building Standards Code, Title 24 of the California Code of Regulations is hereby adopted by reference. Copies are on file in the offices of the Building Official.

Full Breakdown

01 adopts the 2022 California Green Building Standards Code, published by the California Department of Housing and Community Development's Division of Codes and Standards, as adopted and amended by the California Building Standards Commission in Title 24 of the California Code of Regulations. The city keeps copies on file in the offices of the Building Official, the same office that administers every other Title 8 code. The chapter has been amended repeatedly since its first adoption: Ordinance 2045-C-S (2010), 2073-C-S (2013), 2122-C-S (2017), 2175-C-S (2020), and 2226-C-S (2023) each updated the reference to track the state's triennial code cycle.

Antioch does not layer a separate local green-building chapter or numeric add-on onto the state minimums the way it does for plumbing's earthquake shutoff-valve rule; CALGreen's mandatory measures apply as the state adopted them. 01(A), which makes it unlawful to violate any provision of any code adopted by reference by this code and classifies the violation as a misdemeanor unless the City Attorney reduces it to an infraction. 06 directs that the fee actually charged is whatever the city's Master Fee Resolution sets, not a dollar figure printed in the state code.

Violations & Fines

CALGreen isn't reprinted with its own penalty clause in Antioch's code, so a violation falls under section 1-2.01(A)'s citywide rule that breaking any provision of any code adopted by reference is unlawful and, absent a City Attorney reduction to an infraction under Penal Code § 19.6, a misdemeanor under Penal Code § 19, with each day of a continuing violation treated as a separate offense.

Frequently Asked Questions

Does Antioch have its own green building code?
No. Section 8-7.01 simply adopts the 2022 California Green Building Standards Code by reference, the same statewide CALGreen code the Building Standards Commission publishes in Title 24. Antioch hasn't added a local chapter of its own numeric green-building requirements the way it has for plumbing or fences.
What happens if a project doesn't meet CALGreen requirements?
It's treated the same as violating any other adopted building code. Section 1-2.01(A) makes violating any code the city has adopted by reference unlawful, ordinarily a misdemeanor under Penal Code § 19 unless the City Attorney reduces the charge to an infraction under Penal Code § 19.6.
Who enforces the green building code in Antioch?
The Building Official, out of the same office that keeps the code's file copy and administers every other Title 8 building code chapter, from the 2022 Building Code through the 2022 Plumbing, Electrical, and Green Building Standards Codes, per section 8-7.01.
