Building Work You Can Do Without a Building Consent – Wairarapa Guide
Planning building work on your property? In many cases, small-scale building work can be carried out without a building consent under Schedule 1 of the Building Act 2004.
In the Wairarapa, some low-risk building work can be carried out without a building consent under Schedule 1 of the Building Act 2004, provided Building Code and council rules are met.
This page explains what building work may not require a building consent, based on guidance from the Ministry of Business, Innovation and Employment (MBIE), and is specifically tailored to the Wairarapa, including Masterton, Carterton, and South Wairarapa.
This guide is written for homeowners and property owners who want clear, practical information before starting a project.
Important Wairarapa-Specific Information
Even when a building consent is not required, local council rules may still apply. These can include:
• Boundary setbacks
• Site coverage limits
• Building height rules
• Flood hazard areas
• High wind and seismic zones
• Fire separation requirements
These rules apply across:
- Masterton District Council
- Carterton District Council
- South Wairarapa District Council
It is important to check both building rules and district plan rules before starting work.
What “No Building Consent Required” Really Means
“No building consent required” does not mean “no rules”.
All building work must still:
- Comply with the New Zealand Building Code
- Be structurally sound
- Be weather-tight
- Be safe to use
Councils can still take enforcement action if work is unsafe or does not meet the Building Code, even if a consent was not required.
Common Building Work That Does NOT Require a Building Consent
Small Detached Buildings (Up to 30m²)
Examples include:
- Garden sheds
- Sleepouts
- Home offices or studios
You do not need a building consent if ALL of the following apply:
- Floor area is 30m² or less
- Building is single storey
- No plumbing, toilets, or drainage
- Not a self-contained dwelling
- Built to comply with the Building Code

Decks and Platforms
A building consent is not required if:
- The deck is no more than 1.5 metres above ground level
- It does not support another structure
- It does not encroach over boundaries
- It is structurally sound and safe
Fences and Retaining Walls
Fences
- Up to 2.5 metres high
Retaining walls
- Up to 1.5 metres high
- Must not support buildings, driveways, or surcharge loads
Internal Alterations and Renovations
A building consent is generally not required for:
- Replacing wall linings such as plasterboard

- Bathroom renovations
- Like-for-like replacement of fixtures and fittings
Important note:
Removing or altering load-bearing or structural walls requires a building consent.

Repairs and Maintenance
A building consent is not required for general maintenance and repair work, including:
- Like-for-like roof replacement
- Replacing windows or doors (same size and location)
- Repairing or replacing cladding
- General maintenance work
Building Work That STILL Requires a Building Consent
A building consent is required if any of the following apply:
- The building is larger than 30m²
- Plumbing or drainage is installed
- The building is self-contained
- Structural or load-bearing walls are removed or altered
- Fire separation or boundary rules are affected
- The building is used for rental or habitable accommodation
These are some of the most common areas where homeowners unintentionally breach the rules.
Common Wairarapa Mistakes We See
- Building too close to boundaries
- Assuming “no consent” means “no council involvement”
- Adding plumbing to a sleepout later
- Ignoring high wind or seismic requirements
- Using a sleepout as a rental dwelling
- Ignoring high wind or seismic zone
- Work not completed as per the building code
Avoiding these mistakes early can save significant time and cost.

Some low-risk building work can be carried out without a building consent under Schedule 1 of the Building Act 2004. Common examples include small detached buildings up to 30m² with no plumbing, low decks up to 1.5 metres high, fences up to 2.5 metres, certain retaining walls, internal non-structural renovations, and general repairs and maintenance. All work must still comply with the New Zealand Building Code and local council planning rules.
No. Even when a building consent is not required, district plan rules still apply. This can include boundary setbacks, height limits, site coverage rules, flood hazard areas, fire separation requirements, and other planning controls set by local councils.
A sleepout may not require a building consent if it is a detached building of 30m² or less, is single storey, has no plumbing or sanitary fixtures, and is not used as a self-contained dwelling. The building must still comply with the Building Code and local planning rules.
Fences up to 2.5 metres high generally do not require a building consent. Retaining walls up to 1.5 metres high may also be consent-free if they are not supporting buildings, driveways, or surcharge loads. Taller or more complex structures may require a building consent.
Many kitchen and bathroom renovations do not require a building consent if the work is non-structural and does not involve restricted building work. If structural or load-bearing walls are altered, or if plumbing and drainage work triggers consent requirements, a building consent may be needed.
A building consent is required for buildings over 30m², self-contained dwellings, work involving plumbing or drainage, removal or alteration of load-bearing walls, work affecting fire separation or boundaries, and buildings intended for rental or habitable accommodation.
