San Francisco has some of the most particular demolition permit requirements in California. The process is more involved than San Mateo, Sacramento, or most East Bay cities – and the timeline can stretch from 6 weeks to several months depending on the property, the project type, and whether the neighborhood triggers additional review.
This guide walks the actual steps, what each one costs, how long each takes, and the gotchas that catch most homeowners off guard.
Who needs a San Francisco demolition permit?
You need a permit from the San Francisco Department of Building Inspection (DBI) for any of the following:
- Removing more than 50% of an exterior wall
- Removing more than 65% of a roof
- Removing a structural floor, foundation, or load-bearing wall
- Demolishing any standalone structure – even a detached garage or shed
- Removing interior walls if they’re load-bearing or contain plumbing/electrical/HVAC
Interior cosmetic work (kitchens, baths, finishes) typically falls under a building permit, not a demolition permit – but plan-check is still required.
The 7-step San Francisco demolition permit process
Step 1: Pre-application and Section 317 review
San Francisco’s Planning Code Section 317 protects residential housing units. If you’re demolishing a residential structure (even partially), Planning reviews whether the demolition causes a net housing loss. This adds 30-90 days for a homeowner-occupied single-family teardown, longer if there are tenants involved.
Step 2: Asbestos and lead clearance
BAAQMD (Bay Area Air Quality Management District) requires a J-Number permit and asbestos survey for any structure built before 1981, which includes the vast majority of San Francisco housing stock. Allow 2-4 weeks for survey, abatement if needed, and BAAQMD clearance. Cost: $500-$3,500 for survey + $3,000-$10,000 for abatement if positive.
Step 3: Utility shutoffs and signoffs
Before DBI will issue a demo permit, you need signed disconnects from PG&E (gas + electric), SFPUC (water + sewer), and AT&T or Comcast if applicable. Each takes 1-3 weeks. Mavco handles this coordination as part of the scope.
Step 4: Neighbor notification
San Francisco requires a 311 notification posted on the property and mailed to neighbors within 150 feet for most residential demos. The notice period is 30 days minimum. Neighbors can file objections that trigger an additional hearing.
Step 5: Demolition permit application
Submit Form 8 to DBI with site plans, structural engineering letter, BAAQMD J-Number, utility signoffs, and the 311 notice. Filing fee: roughly $1,000-$2,500 for residential. Plan check takes 2-6 weeks.
Step 6: Pre-demolition inspection
DBI inspector confirms the structure is disconnected, neighbors are notified, hazmat is cleared, and the site is ready. Schedule the inspection 1-2 weeks before your demo start date.
Step 7: Demolition and final clearance
Permit is good for 180 days from issue. After demolition, a final inspection confirms the lot is cleared, capped, and graded.
How long does the whole thing take?
- Best case (single-family home, no Section 317 issues, fast asbestos clearance): 6-8 weeks from application to permit issue
- Typical: 10-14 weeks
- With Section 317 hearings or neighbor objections: 4-6 months
What it actually costs
- Demolition permit filing: $1,000-$2,500
- BAAQMD J-Number + survey: $500-$3,500
- Asbestos abatement (if needed): $3,000-$10,000
- Utility disconnects: $500-$2,500
- 311 notification + mailings: $200-$600
- Section 317 review (if applicable): $500-$1,500
- Total permit-side cost: roughly $2,500-$20,000 before the actual demolition
Common gotchas
- Don’t start demolition before the permit issues. San Francisco has aggressive code enforcement. A stop-work order plus fines can add weeks and thousands.
- Section 317 can block your demo entirely if the city decides the demolition would cause housing loss. Plan accordingly – sometimes a renovation permit is faster.
- Tenant-occupied properties require a full no-fault eviction protocol before demo permits will issue. Allow extra months.
- Historic district properties require additional Planning review through HPC (Historic Preservation Commission). Add 60-90 days.
