The 2025 California Building Standards Code (Title 24) became effective January 1, 2026, including the California Administrative, Building, Residential, Electrical, Mechanical, Plumbing, Energy, Wildland-Urban Interface, Historical, Fire, Existing Building, and Green Building Standards Codes, plus Fresno County Ordinance Code Title 15 and applicable zoning, grading, fire-protection, accessibility, and local requirements.
