San Francisco Roofing Permits: What Homeowners Need to Know

Roof permits are not the most exciting part of a roofing project, but getting this wrong can create real problems—unpermitted work can affect insurance claims, resale, and code compliance. Here's what San Francisco homeowners actually need to know.

When Do You Need a Roofing Permit in San Francisco?

In San Francisco, you generally need a permit before installing, repairing, or removing roof sheathing. Reroofing is specifically called out in the city's permit guidance. The SF.gov reroofing permit page is the primary reference, and it's worth bookmarking.

For many routine residential reroofing projects, the work can go through the city's Over-the-Counter (OTC) process. Registered contractors can obtain some reroofing permits online when the work does not require plans and the building is an R-3 residential property that is not historical and has no active complaints filed against it. If the work requires plans, if the building isn't eligible for the simple online path, or if the project is larger or more complex, the permit may move into a different review track through the Department of Building Inspection (DBI).

What Does a Reroofing Permit Cost?

As of the city's current reroofing permit page, the fee is $256.62 for single-family homes and duplexes, and $386.22 for other building types. Additional fees are possible depending on project specifics. You can look up permit history for your property using the DBI permit tracking system.

If you need in-person help, the San Francisco Permit Center is at 49 South Van Ness Avenue, second floor.

What Should Your Roofer Handle?

A reputable roofer should make the permit process easier, not more confusing. They should tell you whether the scope requires a permit, pull it when required, and show you where to verify it. The San Francisco Fire Department explicitly recommends that building owners verify the contractor obtained the permit with DBI before work begins. The Fire Department also notes that if the roofer is using a torch, open flame, or LP gas, a separate fire permit may be required.

Before hiring anyone, verify their license through the California Contractors State License Board (CSLB). A licensed, insured roofer who handles permits without hesitation is a basic expectation, not a bonus.

Frequently Asked Questions

Do I need a permit to repair my roof in San Francisco?

It depends on the scope. Minor surface repairs typically don't require a permit, but if the work involves removing or replacing sheathing or qualifies as reroofing, a permit is generally required. When in doubt, check with DBI or ask your roofer to clarify.

How much does a reroofing permit cost in San Francisco?

Currently $256.62 for single-family homes and duplexes, $386.22 for other building types, with possible additional fees. Confirm current pricing on the SF.gov reroofing permit page.

Can my roofer pull the permit, or do I have to do it myself?

Registered contractors can obtain reroofing permits online for eligible residential projects. Your roofer should handle this. If they're vague about permits or suggest skipping the process, that's a warning sign.

How long does it take to get a reroofing permit in San Francisco?

For eligible OTC projects, registered contractors can often get the permit the same day or within a few business days. More complex projects that require plan review will take longer. Ask your roofer for a timeline estimate upfront.
