Historic preservation review — Certificate of Appropriateness (Article 10) or Permit to Alter (Article 11): San Francisco restaurant guide
SF Planning — Historic Preservation
What it is
Exterior work on an Article 10 landmark or any property in an Article 10 historic district needs a Certificate of Appropriateness; buildings in the downtown Article 11 conservation districts need a Minor or Major Permit to Alter. Ordinary in-kind maintenance is exempt.
When a restaurant needs it
The Property Information Map shows Article 10 or Article 11 status and you are changing the storefront, signs, awnings or other exterior features (interior-only work on most buildings over 45 years old still gets a preservation review on the permit).
How to apply
Preservation staff at the Planning counter review minor work administratively (Administrative COA / Minor PTA); larger changes go to the Historic Preservation Commission with the COA or Permit to Alter supplemental application.
Documents you’ll need
- Photos of existing conditions
- Elevations and details of proposed work
- Material and sign specifications
- COA or Permit to Alter supplemental application
Good to know
Properties listed only on the California or National Register (not Article 10/11) get CEQA review but no COA. Check PIM before designing a new storefront.
