Do you need a permit for Roof Replacement in Solano County?
In California, a Roof Replacement requires a building permit.
A building permit is required to replace a roof. Many California cities apply a 25% rule (replacing 25% or more of the roof in 12 months needs a permit; less is treated as a repair), and wildfire (WUI) zones require a Class A fire-rated roof. Minor repairs under about one square (100 sq ft) are usually exempt. Plans are reviewed under the Statewide (CA Codes) code (IRC 2024); apply through City of Fairfield Building Permits and Business Licenses before work begins.
