Advice for landlords

Advice for landlords

Sustainability Trust can help you make sure the home you’re renting out is warm, dry and meets new insulation laws.

Why does it matter?
Housing standards are being raised across New Zealand to improve quality of life and public health. Recent law changes set new standards for ceiling and underfloor insulation in rentals, and houses need to be upgraded by July 2019. Statements of Insulation for tenancy agreements have been a legal requirement since July 2016. 

Why does it need to be checked?
Most rentals are uninsulated or not insulated to the new standards on the install, thermal rating, condition, fit and more. A professional assessment will give accurate information on the house's current status and what is required to get up to code.

How much does it cost? $110 + GST per property, or free if you install insulation with us. We offer discounts to property managers or landlords with multiple properties. *Smoke alarms cost $30+GST, and are installed at assessment so the rental is safe and compliant straight away.

More on Rental Warrant of Fitness assessments

We're a partner in the voluntary Rental Warrant of Fitness scheme which is being rolled out by Wellington City Council and the University of Otago

Bringing the whole house up to standard - not just insulation - is good for your tenants, makes your property more attractive to renters, and reduces maintenance long-term. 

We recommend: 

  • Downloading the self-assessment app (from Google Play or iTunes) to see if your home is likely to pass.
  • Or going through the criteria on paper. You can find the list here, and read the assessment manual which explains all criteria in detail.  
  • If you think your property will pass, book us for a professional assessment. They take about one hour and cost $250. 
  • If your house fails, make repairs and improvements, then rebook. The second assessment is free if done within six months.

For more information see the Wellington City Council website or to book an assessment call us on 0508 78 78 24, option 1.
