Determining street address

The correct street address for a property is based on the higher order road it directly adjoins, as set out in the local planning scheme (for example, local road or district distributor).
If both roads are the same order, the address is based on the main access point to the property - usually the front door.

What is my official address?

Free information in relation to the official address held by Landgate can be found on the Landgate website.

Street numbering design and siting

  • The owner or occupier of the subject property is to paint or affix and maintain the current number upon a conspicuous and visible place on the front of a building on the property or on the fence, wall, or letterbox adjacent to the road fronting the property, within 14 days after the property is first occupied.
  • Numbers are to be legible, clearly displayed and visible from the road.
  • The letterbox must be located on the front boundary of the property, close to the main access with the allocated street number clearly displayed.
  • Large reflective numbers are recommended.
  • The minimum dimension for each number on a residential letterbox is 75mm high.
  • The minimum dimension for each number on a non-residential property is 150mm high.
  • Numbers painted on kerbs are permitted provided they meet the following:
  • For barrier kerbs, numbers shall be located on or near the kerb returns of the crossover. For mountable kerbs, numbers shall be placed on the side that most closely aligns with the centre of the house frontage.
  • The size of the number shall be a minimum of 120mm x 60mm with 30mm spacing and 30mm edge clearance. The background patch should be 180mm x 240mm, depending on the kerb face.
  • The colour of the numbers shall be reflective yellow, located centrally in the background patch which shall be all green.
  • The City will only replace painted numbers on the kerb line where the kerb has been removed and replaced as part of an upgrade of the road. All other replacements will be the responsibility of the house owner.

Street numbering

  • Street numbers are consecutive and sequential, ranging from lowest to highest, with odd and even numbers on opposite sides of the street.
  • Street numbers for subdivisions, amalgamations, survey strata and strata subdivisions will be allocated at the subdivision clearance/endorsement stage.
  • Where there is only one street number available, developments will be allocated suffixes such as 1A, 1B, 1C, or 1/10, 2/10 etc.
  • Every lot will be allocated a street address, including reserves, schools, public utilities, drainage reserves and the like. Usually, one street address will be allocated per lot, but if foreseen by the City and where possible, additional numbers will be set aside to allow for the development potential of the subject lot.
  • Where a street number has been allocated to a property, then that number must be used. The City will only consider changing the number if there are difficulties identifying the property.

Request to change numbering

If you have having difficulties with your address e.g. when receiving mail/deliveries etc. please raise a request below to request a change of address.
Requests to change a street address must be submitted in writing below, and include evidence of ownership of the property and reasons for request.

Unsupported requests

The City cannot accept requests for a change in street address in the following circumstances:
  • the number is considered unlucky
  • religious reasons
  • to improve the 'feng shui' of the property
  • personal preferences
  • the number is not good for business
  • the property is difficult to sell
  • the number/address is perceived to devalue or add value to the property
  • is contrary to this information sheet

Street naming

  • The Land Administration Act 1997 requires developers of new subdivisions to submit street names for approval by the Council, before being determined by the Minister for Lands.
  • New street names (such as where roads are created in new subdivisions) are generally proposed by the developer.
  • An application for road naming will require the support of the City before it is submitted to Landgate for approval. Landgate then assesses the proposal in accordance with Geographic Names Committee Guidelines.
  • The renaming of roads is discouraged unless there is a good reason for requesting the change. Typical reasons are redesign of a road, changed traffic flow, mail delivery problems, misspelling of a name and duplication problems.
  • Whilst individuals can request road re-naming, proposals will require the support of the City of South Perth Council, with the Minister for Lands having the final authority on such matters.

Raise a Request

  • To request a change of numbering, raise a request below.
  • Please include evidence of ownership of the property and reasons for request.
  • An officer with review and respond within 10 business days.
