The short version
In short: In Calabasas, no roof repair, recovering, or replacement can start without a reroof building permit. Because the city is a Very High Fire Hazard Severity Zone, the new roof assembly must be Class A rated, and wood shake or shingle roofs aren’t allowed. The permit goes to a licensed roofing contractor or a verified owner-builder, and the city inspects the work before signing off.
Permit first
No roof repair, recovering, or replacement work may begin without a reroof building permit.
Class A required
Calabasas is a Very High Fire Hazard Severity Zone; roof assemblies must be Class A rated.
No wood roofs
Wood shake and wood shingle roofs are not allowed in the City of Calabasas.
Licensed contractor
Reroof permits go to a licensed roofing contractor (or a general contractor on multi-trade projects) or a verified owner-builder.
How a Calabasas reroof permit works
- Confirm your jurisdiction.Properties inside city limits are permitted by City of Calabasas Building & Safety. Some homes with a Calabasas mailing address are in unincorporated Los Angeles County, which has its own process.
- Check zoning and HOA approvals.If your property is in the city’s Scenic Corridor and/or you’re changing the roof material color, a Zoning Clearance may be required before submitting to Building & Safety. Many HOAs also require architectural approval.
- Prepare the application.The city’s reroof worksheet is submitted with an aerial view of the roof and documentation showing the roofing materials and underlayment meet code, including the Class A listing.
- Check the weight.If new tile weighs more than 7 pounds per square foot, or more than the existing roofing, a licensed engineer or architect may need to provide structural calculations or plans.
- Pass the inspections.The city requires a roof nailing or roof deck inspection during the project, followed by a final inspection.

Requirements at a glance
| Topic | What it means for your roof |
|---|---|
| Fire rating | Class A roof assembly, tested to ASTM E108 / UL 790 and installed per its listing. See our Class A roofing guide. |
| Materials | Clay tile, concrete tile, Class A asphalt shingles, and many metal and low-slope systems can qualify. Wood shakes and shingles cannot. |
| Ventilation | Attic ventilation must meet code. Because Calabasas is a Very High Fire Hazard Severity Zone, new or replaced vents must resist embers and flame: listed ember-resistant vents, or noncombustible, corrosion-resistant mesh with 1/16″ to 1/8″ openings where allowed. |
| Inspections | Roof nailing / deck inspection plus final. |
| Heavy tile | Structural calculations may be required when new tile weighs more than 7 lb per sq ft or more than the existing roofing. |
| Color changes | Possible Zoning Clearance if you change roof color or your property is in the Scenic Corridor; HOA approval where applicable. |
| Energy code | Replacing or recovering half or more of a steep-slope roof triggers Title 24 cool-roof minimums in Calabasas’ climate zone (aged solar reflectance 0.20 and thermal emittance 0.75, or SRI 16), using CRRC-rated products, unless an exception applies, such as certain tile installations or high attic insulation. |
Wildfire hardening while you reroof
While the roof is open during a roof replacement, we can also close the other gaps embers get through:
- Replace ¼-inch vent screens with ember-resistant vents or fine (1/16″–1/8″) noncombustible mesh.
- Close gaps at the roof edge and under the first course of tile with bird stops or eave closures.
- Add noncombustible gutter guards and keep gutters clear of leaves and needles.
- Use noncombustible or ignition-resistant materials at fascia and roof-to-wall transitions.
