Introduction
Most one- and two-car garages fall under the California Residential Code (CRC) as U occupancies when detached, or as part of the R-3 dwelling when attached; larger or mixed-use garages may trigger the full California Building Code (CBC). Your permit application must include a scaled site plan, foundation and framing details, roof design, and CALGreen and Energy Code documentation for lighting and insulation. Although conventional, single-story wood-frame garages can often be built using CRC prescriptive tables, any design that exceeds those limits—such as tall walls for RV storage, heavy tile roofs, or engineered truss systems—must be stamped and signed by a California-licensed architect or engineer.
