Summary

Every new building and major remodel in unincorporated Glenn County has to meet the California Green Building Standards Code (CALGreen), Title 24 Part 11, which the Board of Supervisors adopted as local law in Glenn County Code Section 15.72.135. The county building official checks a project's mandatory CALGreen measures at the same plan-check stage as the rest of the Building Code.

These county ordinances apply to unincorporated areas of Glenn County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The 2025 California Code of Regulations Title 24, Part 11 also known as the California Green Building Standards Code, copies of which are on file as required by law, are hereby adopted and incorporated into this chapter by reference; are declared to be the green building standards code for the county and shall apply to the unincorporated areas of the County. (Ord. 1285, 2019; Ord. 1260, 2017; 1247, 2013)

Violations & Fines

As with the rest of Title 15's building standards, failing to meet an adopted CALGreen requirement is enforced as a code violation under Glenn County Code Section 1.12.010: a first offense is an infraction, and "every person who violates a particular regulatory or prohibitory provision of this code three or more times is guilty of a misdemeanor for the third and every subsequent violation... during any 12-month period," with each day of continued noncompliance a separate offense.

Frequently Asked Questions

Does Glenn County require CALGreen compliance on new construction?

Yes. Glenn County Code Section 15.72.135 adopts Title 24, Part 11 of the California Code of Regulations, the California Green Building Standards Code, as the green building code for the unincorporated county, so it applies to permitted new construction the same way the Building and Energy Codes do.

Who reviews a project for CALGreen compliance?

The Glenn County Building Department, defined in Section 15.72.140 as "the building inspection division of the county," reviews CALGreen measures at plan check alongside the rest of the adopted Title 24 codes, under the direction of the county building official.

What happens if an adopted CALGreen rule conflicts with another part of the county code?

Section 15.72.160 resolves it in the county's favor: where an incorporated code provision conflicts with an express requirement of Title 15, "the latter shall prevail and be given effect to the exclusion of the former," so the locally written standard controls over the incorporated text.
