Brentwood, CA Building Safety: Roofing Permits (2026)

Roofing permits in Brentwood are issued by the Community Development Department's Building Division at City Hall, 150 City Park Way. Any re-roof that removes and replaces the existing covering requires a permit, as does installation of a new roof, structural repair of rafters or trusses, or the addition of skylights and solar attachments. Re-covers (overlays) are limited to one additional layer per the California Residential Code, and only when the existing roof deck is sound and the combined layers do not exceed structural capacity. All new and replacement roof coverings within Brentwood must be minimum Class A fire-rated assemblies per California Building Code Chapter 7A (Materials and Construction Methods for Exterior Wildfire Exposure), which applies to the entire city given its proximity to CAL FIRE-mapped fire hazard severity zones in the Marsh Creek and Round Valley foothills. Required inspections typically include a nail/sheathing inspection (for tear-offs exposing the deck), an in-progress inspection for underlayment and flashing, and a final inspection. Licensed C-39 roofing contractors or owner-builders may pull permits; owner-builders must sign the state-required disclosure. Permit fees are based on valuation per the city's master fee schedule, and Title 24 cool-roof requirements apply to low-slope roofs on conditioned buildings. Work performed without a permit is subject to investigation fees (typically double the standard permit fee) plus potential code enforcement citations.
