Address Assignment/Change Request

Use this form to request the assignment of an address to your project or a change of assigned address. For information on the addressing process, please see below.

Note that addresses will only be assigned when new development or alteration work is proposed. If no new construction or alteration is proposed, a change of address will ONLY be granted for one of the following reasons:

  1. Your current address is out of sequence with the existing pattern on your block.
  2. The existing entrance on a corner lot is on a different street.
  3. You have documentation that demonstrates difficulty in receiving mail or emergency services.

After an official address is assigned, the owner shall cause the number to be displayed upon the building or land in such manner as to be visible from the street.

OWNER INFORMATION

ADDRESS ASSIGNMENT PROCEDURES

Addresses are assigned in standardized patterns so as to promote speedy response by emergency personnel, as well as provide convenience generally in identifying and locating properties.

Addresses will not be assigned out of numerical sequence. Owner of properties with out-of-sequence addresses are encouraged to request a change of assigned address so as to conform to the overall pattern of addresses.

Addresses will be assigned in pattern consistent for the street. Streets typically have odd-numbered addresses on one side of the street and even-numbered addresses on the other.

Individual addresses in multi-unit buildings will be consistently assigned. In multi-unit buildings, all units should be identified by the property’s numerical address, followed by a unit or suite number or letter.  Only where there are sufficient unassigned numbers on the street may unit in a single building be assigned separate numerical addresses.

For properties with an accessory dwelling (ADU) or junior accessory dwelling unit (JADU), the main dwelling must be identified by the numerical address for the property, while the ADU or JADU must be identified by the main dwelling's numerical address and the letter “A". If the property contains multiple ADUs or both an ADU and JADU, the ADU(s) and JADU must be identified by the main dwelling's numerical address and a sequential alphabetical letter.

NOTE:  The City will not assign addresses to illegal dwelling units. Please contact Planning staff if you would like to legalize an unpermitted ADU or visit our ADU webpage for more information.

Once addresses are assigned, city staff will prepare an addressing notice and send it to the US Post Office, San Mateo County Board of Supervisors, San Mateo County Assessor, utility companies, emergency services, and city departments. 

Failure to apply for the Address Assignment application may delay the final inspection of a building permit.

 
Staff may assign a different address if your proposal does not conform to the above address assignment procedures.
