Rental Property Requirements

Healthy Homes Standards – Insulation

We can help you assess and meet your Insulation requirements for your rental property with our knowledgeable, experienced assessors.

Ceiling and Underfloor Insulation has been compulsory in all rental homes since July 2019. The Healthy Homes Insulation Standard builds on the current insulation requirements.
Under the Heathy Homes Insulation Standard, existing Insulation may need to be topped up or replaced if it is not in a reasonable condition.


Existing ceiling insulation needs to be at least 120mm thick. If not it will need a top-up to reach a minimum of R2.9.


Domestic living spaces with suspended floors must have underfloor insulation that had an R.Value of at least 1.3 when it was installed. The Insulation must be in reasonable condition. Existing Foil insulation that is in reasonable condition will meet the Healthy Homes Standard only if it meets the R1.3 criteria.

Where the foil is not in reasonable condition, such as where it is damaged, ripped or no longer shiny, it will need to be replaced with new underfloor insulation that is not foil and meets the minimum R.Value requirement of R1.3. Retrofitting or repairing foil has been prohibited under the Building Act since 1 July 2016.

All private rentals must comply with the Healthy Homes Standards within 90 days of any new or renewed tenancy after 1 July 2021.

If you are unsure if your rental property is up to the Healthy Homes Standards, we are happy to check this for you and also issue you with an Insulation Statement if it passes or a Free No Obligation Quote for any remedial work that is necessary.
