As of 2026-05-31, residential reroof projects in the City of San Diego typically require a building permit from the Development Services Department (DSD), typically filed by a C-39 licensed roofing contractor authorized to perform the work. California Title 24 Building Energy Efficiency Standards 'cool roof' requirements typically apply when 50% or more of the roof surface over conditioned space is replaced — for low-slope roofs this typically means installing a Cool Roof-rated (CRRC) labeled and certified product meeting minimum Solar Reflectance Index (SRI) thresholds; alternative-compliance paths (additional attic insulation, radiant barrier, R-value above the deck) may apply for steep-slope assemblies. Properties containing a structure 45 years or older may trigger a DSD historical resource review; properties containing a designated historical resource or located within an adopted historic district always require a permit for renewal of roof coverings, and additional historical review applies before DSD will issue the reroof permit (per Information Bulletins 580 and 581). If the reroof involves removing, reinstalling, relocating, or altering existing solar PV, HVAC, or other rooftop equipment, additional electrical or mechanical sub-trade permits are typically required. Verify current DSD submission requirements, Title 24 compliance path, historical-resource status, and any solar-attachment scope with DSD before scheduling the reroof.
