Consent for Portable Cabins in NZ: Do I Need It?

1. What Is Consent, and Why It Matters

When you install a portable cabin on your property, there are two main types of consent to consider in NZ:

• Building consent — for structural safety, foundations, services, and code compliance.

• Resource consent — for planning rules like zoning, setbacks, coverage, and whether a second dwelling is allowed.

2. NZ Council-by-Council Consent Breakdown for Portable Cabins

Auckland (Auckland Council)

• According to Auckland Council, a detached sleepout or cabin without cooking or toilet facilities may not need building consent—but only if it meets certain conditions (size, location, no new sanitary services).

• If you want to include a kitchen or bathroom, the cabin is treated as a minor dwelling and will require both building consent and possibly resource consent.

Waikato District,

• Under the Waikato District Plan, rules for accessory buildings/home occupation apply. For example, an accessory building used as a “home occupation” may be permitted up to 40 m² gross floor area depending on zone and activity.

• If your cabin goes beyond permitted standards (floor area, height, setback), you may need resource consent.

General Terms

• According to general MBIE / Building Performance guidance, a detached building (like a small cabin) without kitchen or bathroom can usually avoid building consent under Schedule 1 exemptions, provided it meets the Building Code.

• However: if you add plumbing or cooking facilities, the exemption no longer applies and you will need building consent.

  
  

3. Upcoming Changes to Watch (early 2026)

• The New Zealand Government is planning a building consent exemption for “granny flats” up to 70 m², scheduled to come into force in early 2026.

• Conditions for this exemption: simple design, work overseen or done by a Licensed Building Practitioner (LBP), and compliance with the Building Code.

• Even when exempt, you may still need to notify your local council.

🛠️ FAQ — Quick Answers

Question	Short Answer
Do I always need building consent for a studio cabin?	Not always — small cabins (sleepouts) without kitchen or bathroom may qualify for Schedule 1 exemption if built to code.
What if I want a self-contained cabin (with bathroom or kitchen)?	Then you likely do need building consent — and possibly resource consent, depending on local rules.
Will the new 70 m² exemption help me?	Possibly — when the law changes (expected early 2026), small standalone dwellings up to 70 m² may be exempt from building consent if conditions are met.
What should I do first?	Contact your local council to: 1. Check district plan rules (zoning, setbacks). 2. Confirm whether resource consent is required. 3. Ask about building consent needs given your cabin’s size and facilities.
