The new Granny Flat rules are a building consent exemption for small standalone homes.

They allow you to build a minor dwelling up to 70sqm without going through the full building consent process — if your project qualifies.

It’s not a free-for-all.
There are still rules around size, location, services, and who designs and builds it.

Here’s how it works:

1. Check if your property qualifies

Every site is different.

You must confirm:

• Your local council rules allow a minor dwelling on your property
• The size is under 70sqm
• It meets boundary setbacks and height limits
• Services like water and wastewater can connect compliantly

If it doesn’t qualify, the standard building consent process is still available as a fallback.

2. Apply for a PIM (Project Information Memorandum)

Instead of a full building consent, you apply for a PIM through your local council. This must be done by a certified professional, and the customer cannot submit it themselves.

This confirms key planning details such as:

• Zoning
• Site restrictions
• Infrastructure requirements

This step ensures you’re building in the right place and meeting local rules.

3. Design must meet NZ Building Code

Even though building consent may be exempt, the home must still comply with the New Zealand Building Code.

That means:

• Proper structure
• Insulation
• Fire safety
• Plumbing and drainage compliance

You’re building a real home, not a shed.

4. Construction and sign-off

A qualified builder must complete the work properly, in this case, HouseMe

Council inspections may not be required in the same way as full consent, but compliance still matters. Insurance, resale value, and safety all depend on it.

The key point

The new rules make the process faster and simpler — if you qualify.

If you don’t qualify, you simply go through the normal building consent pathway, which has always existed.

Either way, there is always a pathway to build.
