San Ramon, CA Building Safety: Roofing Permits (2026)

Reroofing in San Ramon is regulated under the California Building Standards Code (Title 24) as adopted by the City. San Ramon contracts with Contra Costa County for building permit services, and applications are filed through the County Building Inspection Division with coordination through the San Ramon Planning Services Division. A building permit is required for any reroof that replaces more than one layer, involves structural sheathing changes, or adds weight to the roof assembly. Because portions of San Ramon lie within or adjacent to State Responsibility Area (SRA) and Local Responsibility Area Very High Fire Hazard Severity Zones, Chapter 7A of the CBC applies, mandating Class A fire-rated roof coverings (tile, metal, or fire-rated composition shingle). Wood shake and shingle roofs are prohibited on new installations and replacements. Inspections are required for sheathing (if exposed), in-progress, and final. Contractors must hold a valid California C-39 license. Permit fees are based on valuation per the County fee schedule. Title 24 Part 6 (Energy Code) cool-roof requirements apply to most low-slope roofs and to steep-slope roofs in climate zone 12. Solar-ready provisions may apply when reroofing triggers significant structural work. Property owners performing work themselves must qualify under the owner-builder exemption.
