As of 2026-05-31, residential reroof projects in the City of Los Angeles typically require a building permit from LADBS, typically filed by a C-39 licensed roofing contractor registered with LADBS. 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 in a Historic Preservation Overlay Zone (HPOZ) require HPOZ clearance from City Planning before LADBS will issue the reroof permit — this is reviewed under LAMC §12.20.3 and processed as a Certificate of Appropriateness, Certificate of Compatibility, or Conforming Work on a Contributing/Non-Contributing Structure, depending on the project scope. 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 LADBS submission requirements, Title 24 compliance path, HPOZ status, and any solar-attachment scope with LADBS and City Planning before scheduling the reroof.
