Addressing IN THE CITY OF SAN ANTONIO
Addresses are assigned using the City’s Addressing Grid which follows a formula of one address for every 50 feet in increments of four (i.e. 502, 506, 510, etc.). After an address is calculated, adjustments may be made to ensure a new address assignment is within the sequence of addresses assigned. Addressing residential and non-residential properties includes building and suite numbers, accessory structures, and legal descriptions.
It is important to use an address that is officially assigned by the City of San Antonio. Using an alternative or unofficial address could result in an unnecessary delay in emergency response times, mail delivery and would delay building permit and utility services.
For further information on the assignment of addresses including building, suite, unit or apartment numbers, please refer to:
