Summary

Fresno County adopts the 2022 California Green Building Standards Code by reference for every new building permit issued in the unincorporated area. County Code Chapter 15.22 layers on a local landscaping rule: the state Model Water Efficient Landscape Ordinance under Title 23 of the California Code of Regulations governs irrigation and plant choices on top of the base CALGreen standards administered by the Building Official.

City-specific rules exist: Clovis, and Fresno have their own green building code rules that differ from Fresno County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Full Breakdown

22 of the Fresno County Code, titled Green Building Standards Code, contains just two operative sections. 010 adopts the 2022 California Green Building Standards Code, commonly called CALGreen, by reference for all construction within the unincorporated county. That adoption folds mandatory measures on construction waste diversion, water conservation fixtures, and building commissioning into every building permit reviewed by the Fresno County Department of Public Works and Planning, Development Services Division. 7, the Model Water Efficient Landscape Ordinance (MWELO), which sets maximum applied water allowances and plant-factor calculations for new landscaping tied to a building permit.

Both sections were most recently reenacted by Ordinance No. 23-001 on February 28, 2023, which also updated the county's building code chapters to the 2022 edition cycle; earlier amendments trace back to Ordinance No. 11-005 in 2011 when the chapter was first adopted. Because Fresno County incorporates CALGreen and MWELO by reference rather than writing its own numeric green-building standard, a builder pulling a permit in the unincorporated area works from the state code text itself, checked at plan review by county building staff against the adopted 2022 edition. There is no separate county point-count or local exceedance requirement beyond the state baseline in this chapter.

Violations & Fines

Building without CALGreen-compliant plans, or landscaping a permitted project without meeting MWELO water-budget calculations, is treated as a building code violation. The Building Official can withhold final inspection sign-off and the certificate of occupancy until the required CALGreen measures and landscape documentation package are verified, and can require corrective work before recording final approval.

Frequently Asked Questions

Does Fresno County have its own green building code?
No. Fresno County Code Section 15.22.010 adopts the 2022 California Green Building Standards Code (CALGreen) by reference rather than writing a separate local standard. Every building permit application in the unincorporated county is checked against that state code text at plan review by the Development Services Division, so the applicable requirements are the same numeric CALGreen tiers used statewide.
Does new landscaping need to meet a water-budget rule too?
Yes. Section 15.22.020 adopts the state Model Water Efficient Landscape Ordinance, found at Title 23 of the California Code of Regulations, Chapter 2.7, by reference. Projects that include new or rehabilitated landscaping tied to a building permit have to submit landscape documentation showing compliance with the MWELO water-budget calculation before the county signs off.
Who enforces the green building requirements?
The Fresno County Building Official, within the Department of Public Works and Planning's Development Services Division, reviews CALGreen and MWELO compliance during plan check and inspects the completed work before issuing final approval. Noncompliant plans are returned for correction, and a project cannot receive its certificate of occupancy until the adopted 2022 CALGreen measures are verified in the field.
