Local requirements worth knowing
Permits and review
San Dimas runs its own Building and Safety Division. Smaller reroofs (under roughly 6 pounds per square foot) can sometimes be issued over the counter, though a pre-inspection may still be required — we confirm which applies to your job.
Wildfire hazard requirements
Parts of San Dimas fall within a Severely High Fire Hazard Zone, where Class A roofing materials are required on both new roofs and reroofs of existing buildings. Verify your parcel’s current designation — CAL FIRE updated the maps in 2025.
CAL FIRE ran its first comprehensive statewide map revision since 2007 in early 2025, adding roughly 1.2 million acres to the High and Very High severity zones — some of it inside city limits that were never regulated before. Check your specific parcel at CAL FIRE's Fire Hazard Severity Zone viewer rather than assuming based on your street or your neighbours.
Codes and hazard designations change, and they vary by parcel. We confirm the current requirements for your address and jurisdiction before writing an estimate rather than assuming.
