The Gross Rental Value, or GRV, represents the gross annual rental that a property might reasonably be expected to earn annually if it were rented, including rates, taxes, insurance and other outgoings. For non-residential properties, GST is also included.
The GRV is calculated for all rateable and leviable properties in Western Australia regardless of whether the property is being rented or owner occupied.
Who uses the GRV?
Gross Rental Values (GRVs) are provided to rating authorities who use the GRV to work out rates, service charges and levies to be paid by property owners.
These rating authorities include:
Local councils for rates
Water providers (e.g. Water Corporation WA) for water and sewerage rates
Department of Fire and Emergency Services (DFES) for the emergency services levy, which is included on your council rates
Each rating authority sets their own rate in the dollar to be charged. The rate in the dollar is multiplied by the GRV, with the local council adding any levies (e.g. rubbish collection) to calculate the total of rates payable. You should find details of the GRV and rate in the dollar used to calculate your rates in the bill notices received from the respective rating authority.
If you have any queries on the rate in the dollar or levies, please contact the respective local council or rating authority. Any further queries on the GRV, please contact Landgate’s Customer Service team.
How and when is the GRV determined?
All properties within a local government area are assessed at the same date. This date is used by valuers to ensure a fair and equitable assessment is completed for all properties at a given point in time. The assessment date, which is known as the date of valuation or DoV is conducted every 3 years for the metropolitan area and 3 to 6 years for regional areas, depending on the local government. The Gross Rental Value (GRV) remains in force for the respective 3 to 6 year period, until the next GRV is calculated.

Valuers at Landgate collect rental evidence at the date of valuation. The rental evidence is analysed to establish property market levels, with individual property attributes considered to determine a fair rental value for each property.
Given the time it takes to collect and analyse evidence and calculate new GRVs for all Western Australian properties, there is a delay between the date of valuation and the date the valuations are applied by local governments. For local governments located in the metropolitan area this timeframe is 23 months between the date of valuation and the effective date (when they can apply the valuation to generate rates, taxes or charges). For local governments located in regional areas this timeframe is 11 months.
How is the GRV determined for land with no buildings?
For land that is undeveloped, a Gross Rental Value (GRV) is still determined by Landgate. As rental evidence cannot be used for this assessment, a statutory valuation of three per cent of the Unimproved Value is applied to properties designated as residential and five per cent for properties designated as non-residential.
These assessments are conducted in line with the GRVs generated from rental evidence and have the same date of valuation. This date is used by valuers to ensure a fair and equitable assessment is completed for all properties at a given point in time.
Can my GRV be recalculated annually?
Landgate conducts over 2.4 million valuations (as at 1 July 2021) on land in Western Australia with a growth rate of 1.0% to 1.5% per annum. Due to the volume of valuations and expansive land area of Western Australia to be covered, it has been deemed by the Valuer-General that the most cost-effective approach is to conduct Gross Rental Values (GRVs) on a 3 year basis for the metropolitan area and 3 to 6 years for regional areas, depending on the local government. Completing valuations on a more frequent basis would see higher rates and charges for Western Australians.
What is considered when calculating the GRV?
Several attributes and constraints are considered when determining the Gross Rental Value (GRV) of a property. These may include:Residential
Location
Age, building area and construction materials
Number of bedrooms and bathrooms
Number of car shelters (carports / garages)
Below ground pools
Views, busy roads, or proximity to an industrial precinct.
Non-residential
Location
Age, building area and construction materials
Street exposure and property access
Proximity to main arterial roads and primary commercial precincts.
What happens when improvements or changes are made to my property?
Your local council or water provider will advise Landgate of any additions, improvements or demolitions, subdivisions, or amalgamations that have been actioned on your property.
Landgate valuers will review rental evidence as at the latest date of valuation, updating the Gross Rental Value (GRV) to reflect the changes that have been made to your property as if they were in place as at the latest date of valuation.
The new GRV will be provided to the rating authorities, which includes your local council, who will recalculate your rates and taxes for the remaining period in the current financial year. A rates or taxes adjustment notice will be issued by the rating authority advising of any additional charges or if a refund is due to you.
