San Bernardino County enforces the California Green Building Standards Code (CALGreen, Title 24 Part 11) on all new construction and major remodels. Mandatory measures include water-efficient fixtures, EV-ready wiring, construction waste diversion, and indoor air quality controls.
CALGreen mandatory measures cover residential and nonresidential projects countywide. Water fixtures must meet maximum flow rates, irrigation must follow MWELO, and at least sixty-five percent of construction waste must be diverted from landfill. New homes require EV-ready wiring with conduit and panel capacity. Cool roofs and high-efficiency HVAC support Title 24 Part 6 energy compliance. SBC Building and Safety verifies CALGreen forms during plan check and inspections, especially in desert heat-island communities like Victorville and Hesperia.
Permit denial, stop-work orders, and refusal to grant final certificate of occupancy. Repeat noncompliance may trigger code-enforcement penalties under Title 1 fines.
