Request a new building address

If you are altering a property line, adding new condominium spaces, subdividing a property or creating a new parcel (block/lot), you need to hire a California-licensed surveyor to map the new parcel or street and subdivision, in some cases.

This information will reflect the new parcel and will be submitted to the Department of Public Works, the Board of Supervisors (if necessary), and the Office of the Assessor-Recorder for evaluation and incorporation into the City’s base map and property tax roll.

If you already have a parcel number (block/lot), confirm that it is associated with the property on the San Francisco Property Information Map (SFPIM). Click the link and then enter the block/lot. Once you have confirmed that your parcel is recorded with the City and associated with the existing address, you can skip ahead to Step 3 and submit an Address Request Form to DBI.

Property Mapping

If your project includes a property line change, you will need to submit a tentative map of the existing and proposed conditions for approval by the City and County surveyor at the Department of Public Works. An individual licensed to survey in California must prepare the tentative map.

Public Works will circulate the tentative map for departmental approvals and confirm the project complies with City regulations.

Street Mapping

If your project includes an alteration that may modify the Public Right of Way, you must coordinate with the Department of Public Works to have your alteration approved and incorporated into the City’s basemap, which is used to define San Francisco’s streets, sidewalks, parcels and public spaces.

Get information on street mapping.

Subdivision Mapping

If your project will create a new parcel, you need to legally establish the new block/lot by receiving approval from the City and County surveyor in the Department of Public Works. An individual licensed to survey in California must prepare the tentative map on behalf of the property owner.

Get information on subdivision mapping.

When five or more parcels are being established, Public Works will send the new map to the Board of Supervisors and recommend approval. Once the Supervisors approve the new map, it gets returned to Public Works for the County Surveyor’s final approval.

The new map is then sent on to the Office of the Assessor-Recorder for filing and updating the City’s tax roll. The owner of the new parcel will receive an official notice of assessed values for the new parcels in the subsequent fiscal year.

If you are constructing, adding or altering a structure, you will need a building permit and construction inspections. Address change requests that do not involve physical changes to a property (construction) also require a building permit and inspection.

In addition, you also need to submit an address request form so the City can create a new address and connect it to your newly established parcel.

If the address change request does not include any construction, you just need to submit an addressing request form. Department staff will complete and submit the building permit on your behalf.

Address requests with construction

If your project includes construction, prior to submitting a building permit application, email DBI to verify the appropriate address range for your building’s location. You also need to provide a site plan, or a floor plan, in your email. DBI will respond with recommended address numbers for you to include on the building permit application.

Email DBI for address range verification at dbi.addressing@sfgov.org.

Depending on the scope of your project, you can apply for your building permit in-person for Over-the-Counter review or online for In-House review. Be sure to use the existing address when applying for a building permit.

To construct a new building, apply for your permit using Form 1/2: sf.gov/form1-2.

To add to or alter a building, or add or remove tenant spaces, apply for your permit using Form 3/8: sf.gov/form3-8.

You need to submit an Address Request Form with your building permit application.

Fill out an Address Request Form

Address requests without construction

If you are requesting an address change but not doing any construction, submit an address request form without a building permit application. DBI staff will follow-up and then fill out a Form 3/8 building permit application and submit it for you.

Submit an Address Request Form to dbi.addressing@sfgov.org.

Address assignment

After review and approval by the relevant city departments, you will be issued a building permit with the new building address assigned to the property or an old address removed from the property. You will also receive a job card so the City can document completed inspections.

Once the construction is complete, inspected and approved, DBI will record the building permit as complete and, if required, issue a Certificate of Final Completion Occupancy for the building.
