Rentable Area Survey

At Realserve, we understand that it is critical to know the accurate rentable area of your commercial property and a precise Rentable Area Survey is essential for this.


A Rentable Area survey is a measured survey of the floor space for leasing purposes and is often used to assist with rental calculations or a property valuation.


Our aim is to provide the highest quality floor plan area surveys provided in our unique Rentable Area Survey format that complies with the Method of Measurement as set out by the Property Council of New Zealand (formerly known as BOMA surveys).

Do I require a Rentable Area Survey?

Yes, if you don't have a plan, your plan is not clear, or your plan is not compliant with the current method of measurement guidelines. 


The below questions will assist you in determining whether the plan you have is suitable:


  • Have your plans been prepared by a Rentable Area Survey specialist?


  • Do your plans clearly state a survey date?

- Plans should be ‘as measured’ I.e. NOT based on architectural or marketing drawings

- Have there been multiple revisions? If so, are you sure you have the most current version?


  • Do your plans state that they are measured in accordance with the current method of measurement guidelines?


  • Has the correct method of measurement been applied?

- Have there been any changes to the premises since the areas were calculated? The method to be used is determined by the use of the premises and the inclusions and exclusions are unique to the different methods.

NOTE: A change in premises use will most likely affect the area and new calculations will be required – for example, the areas may be calculated to the external face of a wall rather than the internal face, increasing the area.


  • Are the plans clear and do they provide the information you need?

- Are inclusions clearly outlined? E.g. Exclusive Zones (Outdoors) and other negotiated areas

- Are exclusions clearly outlined? E.g. Base building areas, voids over stairs, mezzanines, low head heights at stairs, etc.

- Are lease lines labelled? E.g. Line of Tenancy Produced (LTP) where lease lines have been negotiated.
