Spokane Municipal Code

Title 17D City-wide Standards

Chapter 17D.050A Roadway Naming and Addressing

Section 17D.050A.100 Addressing Standards

 

1. Each property owner who has addressable property and has not been assigned an address has a responsibility to apply to the Addressing Authority for a physical address.

2. Application for each address assignment prior to the issuance of a building permit shall include, at a minimum: a site map showing any proposed or existing structures, driveways, and road approach locations and shall be accompanied by an application, as determined by the Addressing Authority.

3. The numbering of addressable properties or structures along each roadway shall begin at the appropriate grid point of origin and continue in sequence. No address shall be out of sequence in relation to the adjacent addresses.

4. Each block along a roadway may have up to one hundred address numbers. The hundred series shall change upon crossing a roadway intersection or in best possible alignment with the established address grid if applicable, with the exception of intersecting driveways and/or alleys. The hundred series along a public roadway shall not change upon crossing a private roadway, unless deemed necessary by the Addressing Authority. Private roadways wholly contained within plats shall be assigned hundred series as if they were public roadways.

5. Addresses along a roadway shall have even numbers on one side of the roadway and odd numbers on the other side as defined in the addressing grid.

6. Individual address numbers shall be assigned to fit within the block range of the roadway segment to which the address is assigned (e.g. a new address that is assigned to the 200 block of Main St., must be assigned a number between 200 and 299). Individual addresses should be assigned to be consistent with adjacent blocks of the same N-S or E-W orientation.

7. Addressable property or structures shall be assigned an address based upon the named travel way from which vehicular access to the property or structure is obtained, with the following exceptions:

1. 1. Commercial and Public Facility structures may be assigned an address based upon the roadway the main entrance faces and not necessarily the access roadway.

1. 2. Residential structures on corner lots, or with vehicular access via an alley or driveway, may be assigned an address based upon the roadway the main entrance faces and not necessarily the travel way providing vehicular access.

8. Fractional addresses shall not be used (e.g., “100 ½ W. Main St.”).

1. Addressing on Shared Driveways and Other Non-Roadways.

1. 1. A road name may be assigned to shared driveways, alleys, access ways to parking areas, and other traveled surfaces that are not considered roadways at the discretion of the Administrator.

1. 2. The requirements in SMC 17D.050A.120 Multiple Units may be used. The administrator may require arrow signs indicating building or address ranges within a grouping of buildings to be placed at entrances and along non-roadway traveled ways to aid in locating buildings.

10. New Addresses in Residential Infill Development.

Infill development in densely-built locations with pre-existing addressing may involve situations where there aren’t enough open numbers within the existing address range on a street. In such cases, the following options shall be considered:

1. 1. A letter may be appended to the address number (e.g., “118A” or “118B”).

1. 2. The standards for multiple units in SMC 17D.050A.120 may be used to provide addresses.

1. 3. If no other feasible option is available , addressing for nearby parcels on the block face may be modified.

1. 4. The Administrator shall determine which method to employ, with an emphasis on consistency and predictability for emergency service providers and other agencies.
