From the first quarter of 2026, homeowners in New Zealand can build small standalone dwellings, such as granny flats, without a full building consent – if specific conditions are met. This simplifies the process while maintaining safety standards. Land covenants and council resource consents still apply.
What’s Changing?
Instead of obtaining a full building consent, homeowners will be able to build small standalone dwellings by meeting specific conditions and notifying their council. Think of it as a streamlined process that still maintains safety standards but cuts through some of the red tape.
Remember though that any other requirements from the land covenants on your title, or the council’s resource consent rules, still apply and are separate from these changes.
Key Requirements
Size and Design:
Your granny flat must be modest and straightforward:
Maximum 70 m², single storey, ≤4 m high
Floor ≤1 m above ground, ≥2 m from boundaries or other structures
Construction Standards:
Comply with the Building Code
Lightweight roof (≤20 kg/m²), timber or steel frame
Self-contained, internal garage allowed
Professional Oversight:
Here's something crucial: all work must be carried out or supervised by licensed professionals. This includes Licensed Building Practitioners (LBPs), as well as licensed plumbers, drainlayers, gasfitters, and electricians. You'll also need proper documentation – Records of Work, Certificates of Work, and energy work certificates for all relevant trades.
Utilities and Services:
Connect to water, sewage, stormwater, and electricity networks
Gas and heating if applicable
Level-entry showers allowed only after new LBP licensing class is established
Council Notification Process
Before You Start:
Submit a Project Information Memorandum (PIM) to your council.
Council provides property info, assesses exemption eligibility, and flags development contributions.
Note: Advice isn’t approval. Full consent may still be needed for hazard-prone land.
You have two years from the PIM date to complete construction.
After Completion:
Within 20 working days, submit final plans and all licensed professional documentation.
Pay any development contributions.
Missing this deadline may incur an infringement.
Natural Hazards:
Properties in hazard-prone areas may still require full consent unless adequate protection measures are in place. This is an important consideration to discuss with your council early in the planning process.
Is This Right for You?
Ideal for housing family, generating rental income, or providing caregiver accommodation. It’s not a free-for-all – the trade-off for skipping the consent process is adhering strictly to the prescribed conditions and ensuring all work is done by licensed professionals.
Non-Compliance:
Buildings not meeting exemption conditions require full consent. Councils retain powers to address non-compliant work.
Looking Ahead
With legislation taking effect Q1 2026, now is the time to plan, engage professionals, and consult your council. Even with exemptions, granny flat projects are significant.
