What the insulation standard requires
Rental properties must meet the Healthy Homes standards unless an exemption applies. For existing Auckland rentals, the insulation requirements generally include:
- When installing new insulation to meet the Healthy Homes standard, a minimum R-value of R2.9 for ceilings and R1.3 under suspended floors.
- Correctly fitted insulation in reasonable condition, without dampness, mould, damage or gaps.
- Checking existing insulation against the rules that apply to its installation date, condition and supporting records.
Older insulation may still meet the standard. We can check what’s there and explain whether a top-up or replacement is needed. New builds and consented renovations have separate Building Code requirements.
