Residential Tenancy Act Insulation Requirements for Landlords

The residential tenancy act changed on the 1st of July 2016 and landlords are responsible for ensuring that the insulation installed in their properties meets the new Residential Tenancy Act insulation requirements for landlords. This document outlays your responsibilities as a landlord. It is important that you comply with the new regulations, as failure to provide adequate insulation is an unlawful act, and you may be liable for a fine of up to $4,000.

The immediate effects of the changes mean you’ll need to declare the extent of insulation in your rental property on new tenancy agreements. As of the 1st of July 2019, the new laws require all rental properties* to have underfloor insulation and ceiling insulation.

*Some exceptions may apply in situations where it is not possible to retrofit installation due to house design or construction. For more information visit

As a landlord you are permitted to install insulation yourself. However, if you install the insulation incorrectly you can face insurance and liability consequences for faulty or negligent installation. Canterbury Insulation recommends the use of an approved installer, who can guarantee the performance of your installation.
