Summary
Unincorporated Kern County builds under the 2025 California Green Building Standards Code, known locally as the Kern County Green Building Code. Section 17.10.020 adopts that portion of Title 24, Part 11 without a single local amendment, and Section 17.10.030 confirms it: no additions, no stricter local thresholds. Every mandatory CALGreen measure applies to new building permits exactly as the state wrote it.

Full Breakdown
Kern County repealed its prior Green Building Code chapter and replaced it wholesale through Ordinance No. G-9359, Section 5, effective November 4, 2025; the former chapter had derived from Ordinance G-8866 (2019) and Ordinance G-9179 (2022), showing the county re-adopts this chapter roughly every state code cycle rather than layering new local text onto it. 020 then adopts, by reference, that portion of the California Building Standards Code, 2025 edition, without amendment. 030 is explicit that no amendments, additions or modifications are included, meaning the county chose not to exercise the local-amendment power it uses heavily elsewhere in Title 17, where the electrical, plumbing and building code chapters all carry pages of Kern-specific tweaks; this chapter carries none.
030: new construction and, to the extent the adopted codes specify, additions and alterations. 070. There is no separate CALGreen permit or fee schedule; compliance is verified as part of the standard building permit issued under Title 17's general fee and inspection framework.
Violations & Fines
Kern County treats a CALGreen shortfall like any other Code of Building Regulations violation: Section 17.04.200 makes any violation of Title 17, including codes adopted by reference, a misdemeanor punishable by up to $1,000 and up to six months in county jail, with each day of continued noncompliance a separate offense. The building official can also declare a noncompliant structure a public nuisance and abate it, and may enter the property under an inspection warrant if entry is refused.
