Healthy Homes Standards
The Healthy Homes Standards is all about making New Zealand residential rental properties warmer and drier and became law on 1 July 2019. They cover requirements for insulation, heating, ventilation, drainage and draught stopping.
What are the new standards?
This section only covers areas of the Healthy Homes Standards where CEA can help.
Insulation that was installed before July 2016 will meet the current requirements if it is in reasonable condition (e.g. no mould, dampness or gaps), and it was at least the minimum R-value when it was installed. After 1 July 2021 the new standards apply for all new, renewed or varied rental contracts. By 1 July 2024 all rental properties will need to comply with the new standards.
Current standards for pre-July 2016 insulation*
- Ceiling R 1.9 (timber-framed homes) or R 1.5 (masonry homes)
- Underfloor R 0.9
New standards for Canterbury and the West Coast
- Ceiling R 3.3
- Underfloor R 1.3
There are exceptions for homes where ceiling or underfloor insulation is impractical to install. Examples of these exemptions are homes with flat or skillion roofs where there is no access to the roof space and homes where there is not enough crawl space under the floor to install underfloor insulation.
From 1 December 2020 all new rental contracts will need to include information about the current level of compliance with the Healthy Homes Standards including the level of insulation.
All private rentals must comply with the draughtstopping requirements of the Healthy Homes Standards within 90 days of any new or renewed tenancy after 1 July 2021, with all private rentals complying by 1 July 2024.
Landlords must make sure the property doesn’t have unreasonable gaps or holes in walls, ceilings, windows, skylights, floors and doors which cause noticeable draughts. All unused open fireplaces must be closed off or their chimneys must be blocked to prevent draughts.
