Valuation information guides

Valuations overseen by the Valuer-General follow strict guidelines in accordance with the Valuation of Land Act 1978. The latest versions of these information guidelines are listed on this page.

Our role in valuations 

Landgate valuers conduct independent and unbiased valuations of your property. Our Rating and Taxing valuers assess gross rental values (GRVs) and unimproved values (UVs) used by local governments, government agencies and emergency services as a basis to determine property rates, land tax, service charges and levies.  

A property owner who does not agree with their GRV or UV may lodge an objection.  

Our specialist valuers deliver:  

  • valuations and consultancy services to determine compensation for dispossessed property owners  
  • the review of market values on property transfers to determine First Home Owners Grant and stamp duty  
  • valuations of mining tenements and business interests as required by RevenueWA  
  • maintenance and assessments of the fair value of the Government Property Register which comprises the land and property records of approximately 70 agencies. 

The Valuer-General’s role 

The Valuer-General sets the standards, policies and information guides used to ensure land in Western Australia is valued for rating and taxing purposes in a consistent, accurate and transparent manner and the valuations determined are fair, just, equitable and correct.
