Ensuring your Rental is Healthy Homes Compliant

Did you know that all managed or private rentals must comply with the Healthy Homes Standards within 120 days of any new or renewed tenancy? The following must be complied with to ensure your property is Healthy Homes compliant.

All rental properties must have one or more fixed heaters, which can directly heat the main living room and meet a required heating capacity. Certain heating devices that are inefficient, unaffordable or unhealthy will not meet the requirements of this standard. A heating assessment tool is provided at tenancy.govt.nz/heating-tool, which provides a report that shows the minimum heating capacity required. It can be used to check if current heating is sufficient to meet the standard, or if it is necessary to install a new heater.

Ceiling and underfloor insulation has been compulsory in all rental homes since 1 July 2019, where it is reasonably practical to install. Underfloor insulation needs a minimum R-value* of 1.3. Existing ceiling insulation may need to be topped up or replaced if it is not in a reasonable condition, and in most situations, existing ceiling insulation needs to be at least 120mm thick. If ceiling insulation needs to be topped up, it needs to meet minimum R-values as set out in the 2008 Building Code.* ‘R’ stands for resistance - an R-value is a measure of how well insulation resists heat flow.

Rental properties must have at least one door or window (including skylights) that opens to the outside in all bedrooms, dining rooms, living rooms, lounges and kitchens. The openable windows and doors must have a total area of at least 5% of the floor area in each respective room. The windows or doors must be able to be fixed in the open position. All kitchens and bathrooms must have an extractor fan that ventilates externally, in good working condition and checked and compliant.

Moisture Ingress and Drainage
Rental properties must have efficient drainage for the removal of storm water, surface water and ground water, including an appropriate outfall. The drainage system must include gutters, downpipes and drains for the removal of water from the roof. If the rental property has an enclosed subfloor, a ground moisture barrier must be installed if it is reasonably practical to do so.

Draught Stopping
Landlords must block any unreasonable gaps and holes in walls, ceilings, windows, floors and doors that cause noticeable draughts. Open fireplaces must be blocked unless the tenant and landlord agree otherwise.
