Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 39).
Full Breakdown
Ordinance No. 120 is the section that specifically adopts the California Green Building Standards Code, 2025 Edition, by reference and without any local amendments. 12, spells out why: the Green Building Standards Code 'shall apply to encourage sustainable construction practices in the planning and design, energy efficiency, water efficiency and conservation, and environmental quality of all newly constructed buildings' in the city. Because CALGreen is adopted with no local amendments, the mandatory and voluntary tiers set at the state level, including construction waste diversion, water-efficient plumbing fixtures and energy-efficiency measures beyond Title 24's baseline energy code, apply in Rialto exactly as the California Building Standards Commission published them.
The building official reviews CALGreen compliance as part of the same plan check and permit process used for the rest of Title 15, and CBC Division II of Chapter 1's administrative provisions, including permit issuance, inspection and reinspection fee rules, govern how green building compliance is enforced. 14.
Violations & Fines
Building or altering a structure in Rialto without meeting the adopted 2025 CALGreen requirements is treated the same as any other Title 15 building code violation: the project cannot pass plan check or receive a certificate of occupancy under CBC Section 111.5, as locally amended, until the building official confirms compliance. Occupying an unpermitted or noncompliant structure exposes the owner to code enforcement action, and continued unpermitted work can trigger reinspection fees and the unpermitted-structure provisions added at CBC Section 105.1.3.
