Which rentals are exempt from the Healthy Homes standards?

Fewer than optimism suggests. The standards apply to every private rental, and the exemptions are deliberately narrow. The most common is partial and practical: where a specific piece of work is not reasonably practicable, underfloor insulation with no safe access is the classic case, the landlord must do what is practicable and can be exempt from the rest of that specific requirement. "Expensive" or "inconvenient" does not reach the bar.

The general exemptions

A small number of whole-property situations exist, including where the property is genuinely scheduled for imminent demolition or substantial rebuild with evidence to match, and certain short-term arrangements such as where the tenant is the property's former owner immediately after a sale. Each has conditions and time limits, and the details are maintained on tenancy.govt.nz. None of them is a standing category a landlord can quietly live in for years.

What every exemption has in common

• It must be true on the facts, not assumed, a professional's written opinion is the right evidence for a practicability exemption.
• It needs records: why it applies, from when, supported by what.
• It ends: circumstances change, access gets created during other work, demolition plans lapse, and the obligation returns with them.

If you believe an exemption applies to your property, write down the reasoning and the evidence the day you form that view, and diarise a re-check. Self-diagnosed exemptions with nothing on file are where Tribunal cases go badly.
