Permits: the City of Santa Clarita, Not LA County
Inside city limits, reroof permits come from the City of Santa Clarita's Building & Safety Division at City Hall, 23920 Valencia Blvd, and are applied for through the city's Accela portal. The city's reroof handout is direct: no reroofing starts without a permit and an onsite preinspection. The preinspection happens once the old layers are off, so the inspector can check the deck for damage and dry rot before anything new goes on.
| Scope of the work | What the city's handout requires |
|---|---|
| Repair under 10% of the roof or 200 sq ft, whichever is less | No permit, if the damaged area is restored to its previous condition |
| 10% to 50% of the roof | Permit; the new portion meets current code |
| Over 50% of the roof | Permit; the whole roof meets current code |
The handout allows at most two layers of composition shingle, and tile goes on one layer only, directly on sheathing. The city's 2025 building code, in force since January 1, 2026, adds that a reroof over spaced sheathing gets new solid sheathing, and that every reroof is inspected after the existing layers come off. We found no express or same-day reroof permit in Santa Clarita.
Addresses outside the city line, such as Stevenson Ranch, an unincorporated Census-designated place, permit through LA County Public Works' Santa Clarita Valley office at 23757 Valencia Blvd instead.

Fire Zones Decide the Roof Class
Santa Clarita requires a Class B roof at minimum, and Class A inside the city's fire hazard zone. The zone follows CAL FIRE's maps, and CAL FIRE published updated maps for LA County on March 24, 2025, so check your parcel on the CAL FIRE hazard map viewer before choosing materials. The valley has history here: the Tick Fire started in Canyon Country on October 24, 2019, burned 4,615 acres and destroyed 22 structures, and the Hughes Fire burned 10,425 acres near Castaic Lake in January 2025.

Title 24: Mostly Zone 9
Most Santa Clarita ZIP codes are Title 24 climate zone 9, one of the zones where a steep-slope residential reroof needs a cool-rated roof product. The California Energy Commission lists 91380 and 91390 in zone 16, which has no steep-slope cool-roof rule, and 91387 isn't in its ZIP list at all, so confirm a Canyon Country address with the CEC's lookup. Exceptions, such as heavy tile roofs and extra attic insulation, are in our Title 24 cool roof guide. Santa Clarita is on Southern California Edison, so LADWP's cool roof rebate doesn't apply, and we couldn't find a cool-roof rebate on SCE's residential rebate pages.

A Housing Stock Coming Due
Santa Clarita grew late. Of about 78,000 homes, 40% were built in the 1980s and 1990s and another 29% in 2000 or later, against 31% before 1980. Homes from the 1980s and 1990s are now 25 to 45 years old. That's the whole expected life of a 3-tab shingle roof (20 to 30 years) and the later years of an architectural one (30 to 45). On a tile roof the tile usually outlasts the underlayment beneath it, which is why a lift and relay is a common answer. If your home is in an HOA, get architectural approval before ordering materials; the city permit doesn't replace it.
