Cases involving unlawful dwellings are increasing in New Zealand. When a property is ruled non-compliant for residential tenancy use, landlords can face severe outcomes, including orders to repay significant rent amounts.
What is an unlawful dwelling?
An unlawful dwelling generally refers to a rental living space that lacks required approvals or does not meet core building and safety standards for legal residential use.

Common warning signs
- Spaces converted for living use without proper consent
- Multiple rental units on one site without compliant approvals
- No clear legal addressing or service identifiers
- Visible internal alterations without documentation
Examples often requiring extra due diligence
- Garage conversions
- Container-style accommodation
- Basement or attic conversions
- Detached minor dwellings built without full consent pathway
Many compliance issues are historical and may pre-date the current owner. However, ownership responsibility still applies. “Not knowing” is rarely a defence once a tenancy dispute reaches formal review.
Best practice: run periodic compliance checks, keep consent documents organised, and engage qualified inspectors when there is any uncertainty. Proactive compliance protects your investment and your tenancy position.
