Local context for San Francisco
San Francisco permits are issued by the Department of Building Inspection, which uses an online tracking portal going back to the 1980s. SF enforces the 2013 Mandatory Soft Story Program, which required retrofits on roughly 4,800 wood-frame buildings with five or more units that were permitted before 1978. California Title 24 energy code, updated for 2025 and effective January 1, 2026, also applies to most remodel and replacement projects.

Several local factors push San Francisco roofing pricing above or below the national baseline:
How does the SF soft-story ordinance affect a small remodel?
If your building is already classified and retrofit is complete, it does not affect most remodels. If the building is soft-story and not yet retrofitted, DBI generally requires the retrofit to be in progress or completed before signing off on major permit work.
Why do San Francisco permits take longer than other California cities?
DBI plan review routinely coordinates with Planning, Historic Preservation, Public Works, and Fire. For projects over 45 years old or in a historic district, expect an extra 4 to 8 weeks for historic preservation clearance beyond the basic DBI review.

Permit requirements in San Francisco follow California state building code plus local amendments. If you check "Existing roof tear-off needed," yes. Tear-off adds about $1.50 per sq ft ($2,550 for a typical 1,700 sq ft roof). Some areas allow a second layer of shingles over the existing roof, which avoids this cost. See our California permit guide for specifics.
Most residential roof replacements take 2-5 days. Metal and tile roofs take longer (5-10 days). Weather delays are common — schedule for dry periods.
Yes, in most jurisdictions. Roof replacement typically requires a building permit ($150-$500). Your contractor should pull it. Check our permit guide for your state.
If your roof is under 15 years old and damage is localized, repair is usually better ($300-$1,000). If it is over 20 years, has widespread damage, or you are seeing granules in gutters, replacement is the better investment.
