Summary

Stanislaus County adopts the 2025 California Green Building Standards Code by reference under Section 16.80.010, making CALGreen's mandatory measures part of the county's building requirements for new construction in the unincorporated area. The county building official keeps a copy on file for public inspection, and the edition was last rolled forward by Ord. CS 1402 on November 18, 2025.

City-specific rules exist: Modesto has its own green building code rules that differ from Stanislaus County's county-level regulations. If you live in Modesto, check the city-specific page instead.

Except as hereafter changed or modified, the 2025 California Green Building Standards Code is adopted by reference and incorporated in this chapter as if fully set forth herein, and shall be referred to as the California Green Building Standards Code of the county. A copy of said code shall be kept and maintained by the building official for use and examination by the public.

Full Breakdown

80 as the county's official green building code for the unincorporated area. As adopted, CALGreen applies its statewide mandatory measures to permitted construction outside the county's nine incorporated cities, each of which separately adopts its own edition of CALGreen for work within city limits. 010 does not itself list local amendments to CALGreen's substantive requirements, unlike the county's more heavily modified fire and building codes elsewhere in Title 16; it functions as a straight reference adoption, with the county building official required to keep a copy of the code available for public examination in the same way as the other codes adopted throughout Chapter 16.

020 clarifies that the California Green Building Standards Code, 2025 Edition, Part 11, operates alongside the county's other adopted codes (Building, Residential, Plumbing, Electrical, Mechanical, Energy) and that Title 16's own provisions govern in the event of a conflict. 040, referencing the California Building Code's own scope-and-administration provisions.

Violations & Fines

A green-building violation is treated like any other Title 16 violation: Section 16.00.070 makes it a misdemeanor, punished per Section 1.36.010, with a second or later conviction at the same property within five years increasing the maximum penalty to a $5,000 fine, six months in jail, or both, under Health and Safety Code Section 17995.1. Noncompliant work can also be declared a public nuisance and abated under Section 16.00.080, and remedies under Chapter 16.00 are cumulative rather than exclusive.

Frequently Asked Questions

Does Stanislaus County require CALGreen compliance for new construction?
Yes. Section 16.80.010 adopts the 2025 California Green Building Standards Code by reference as the county's green building code for the unincorporated area, so new permitted construction there must meet CALGreen's mandatory measures the same way it must meet the adopted Building and Residential Codes.
Has Stanislaus County made its own local changes to CALGreen?
The adoption ordinance, Section 16.80.010, doesn't spell out local amendments to CALGreen's substantive standards the way the county's fire and building code chapters do; it's a reference adoption of the 2025 edition 'except as hereafter changed or modified,' with the current text showing no separate county-specific green-building amendments.
What happens if construction doesn't meet the adopted green building code?
It's enforced the same as any other Title 16 violation: a misdemeanor under Section 16.00.070, punished per Section 1.36.010, with the county also able to declare noncompliant work a public nuisance and abate it under Section 16.00.080. A repeat violation at the same property within five years can raise the fine to $5,000 under Health and Safety Code Section 17995.1.
