What are the Healthy Home Standards?

• Heating

Landlords will be required to provide a fixed heater or heat pump within every living area/lounge room. The heating system needs to be able to heat the living room to at least 18 ̊ C, as this is the indoor temperature recommended by the World Health Organisation.

• Insulation

Insulation in rental properties will need to meet the Ministry of Housing and Urban Development’s definition of “reasonable condition”. This includes having insulation which is a minimum of 120mm thick and meets the 2008 building code requirements of ceiling and underfloor insulation.

• Ventilation

To meet the ventilation standards, you will need to ensure the general living areas of your home, such as bedrooms and living rooms, have openable windows. Additionally, an extractor fan of an approved size must be installed within bathrooms and cooking areas.

• Moisture ingress and drainage

Landlords will be required to, at a minimum, install ground moisture barriers, ensure water removal systems are in place (such as drains, downpipes and gutters) and that ground moisture barriers are installed within enclosed subfloor cavities.

• Stopping draughts

The draught stopping standards require landlords to address and block any obvious draughts from entering the building interior. Obvious areas that will need to be blocked include fireplaces and chimneys that aren’t in use. You will need to keep an eye out for cracks, gaps and holes throughout your property, especially surrounding windows and doors.

Who does it impact?

The new standards will impact both landlords and their tenants. The standards ensure landlords know what property maintenance areas to prioritise and that they will have clear guidelines to abide by.

It will also provide tenants with a clear understanding of what living standards they should expect in any rental property and what maintenance work falls under their landlord’s set of responsibilities.

Hopefully, your rental property already meets the majority of these standards. To be sure, there are a few things to look for:

• As a basic rule, ensure your property meets the minimum requirements of the building code.
• Read over and familiarise yourself with the Healthy Homes Standards.
• Take advantage of the Healthy Homes Standards guides and online tools, keep an eye on the Tenancy Services website for these.
• Hold onto any relevant records of maintenance and installation work carried out on your property
• If you are still unsure, get in touch with a maintenance professional for guidance.

When does my property have to meet these standards by?

Private landlords will need to meet these standards “within 120 days of the renewal or the start of a new tenancy after 1 July 2021”, according to the Ministry of Housing and Urban Development. All rental properties must comply by the 1st July 2025.

What is the heating standard?

• Main living/lounge areas

The lounge area of your rental property must include a fixed heating device that achieves a temperature of at least 18°C. This heating device must meet the requirements of the heating standard in terms of health, efficiency and affordability. Open fires, unflued combustion heaters and many electric heaters will not meet the heating standards.

• Bedrooms

Renters will be responsible for keeping their bedrooms heated as needed/desired. Landlords will only be responsible for providing heating devices within living areas.

How much will it cost for my property to meet the Healthy Home heating standard?

Heat pump installations start from around $2000.

If your rental property does not currently meet the Healthy Homes heating standards, you will be required to update your heating system (unless you meet the exceptions set out in Ministry of Housing and Urban Development’s Healthy Home Standards). Your heating system costs and requirements will depend on the size of the living room, its insulation and windows.

Detailed tools and guides on the heating standard requirements will be provided by Tenancy Services. Further cost information will be available then.

What is the insulation standard?

If you have noticed signs of mould, moisture and water damage within your rental property, it could be a sign that the insulation is not up to standard. To meet the insulation standard, you must ensure your rental property’s insulation:

• Meets the 2008 building code’s ceiling and underfloor insulation requirements
• Meets the 2016 RTA insulation requirements
• Is at least 120mm thick
• Meets the Ministry of Housing and Urban Development’s definition of being in “reasonable conditions” (more clarification on this definition will be provided by Tenancy Services in late 2019).

How much will it cost for my property to meet the Healthy Home insulation standard?

Flooring and ceiling insulation replacements usually cost around $65+ per m2.

Living/habitable spaces e.g. bedrooms, lounge areas, offices and dining rooms

Reducing draughts within your rental property will make it easier for your tenants to heat the house interior and will keep energy bills from soaring. Your rental property will probably meet the draught stopping and moisture standards set out by the Ministry of Housing and Urban Development if:

• There are no obvious draughts occurring within your property
• Fireplaces/chimneys that are no longer in use are blocked/draught proofed
• Efficient sealants are used throughout your property’s windows
• Walls, floors etc. are reasonably draught proofed
• Efficient drainage systems are in place to avoid the build-up of surface waters etc.
• Enclosed subfloor cavities have a ground moisture barrier installed, according to New Zealand regulations
• Roof overflow is avoided through efficient gutter, downpipe and drain installations

How much will it cost for my property to meet the Healthy Home draught stopping and moisture standards?

Costs you may need to/choose to cover include:

• Minor roofing repairs to reduce draughts: $100 - $2000+
• Chimney/fireplace removal: $700 - $4500+
• Guttering installations: $70+ per metre
• Spouting installations: $65+ per metre
• Surface channel installations: $700+ per metre

Unless you meet the exceptions set out in the Ministry of Housing and Urban Development’s Healthy Home Standards, your property will need to meet the Healthy Home Standards by the 2021 deadline. More information detailing the requirements will be provided by Tenancy Services.

*Costs presented here are rough estimates only. For a quote accurate to your specific requirements, please contact a maintenance, repairs or installations professional.

While the final details on the standards are yet to be published, the Ministry of Housing and Urban Development does confirm that there is some work which landlords are legally allowed to carry out themselves. This includes insulation (although an electrician should be contacted if you will be removing foil insulation) and ground moisture barriers. However, if you are not confident in your ability to safely and effectively complete an installation, asking a professional to carry out the installation for you is recommended.
