Quick Answer
In Napier the 2026 national granny flat standard permits one detached unit of up to 70m² on most residential sections without resource consent, across the Main Residential, Western Hills and Ahuriri residential zones. Napier's operative plan predates the MDRS, so multiple dwellings and subdivision run through the district plan's own rules, which our screening treats conservatively while checking the parcel facts that matter here: coastal hazard and tsunami exposure.
A 70m² Granny Flat — the 2026 National Standard
From 15 January 2026 the national standard for detached minor residential units (SL 2025/315) applies in Napier as everywhere in New Zealand: one detached unit of up to 70m² is a permitted activity on sites in residential, rural, mixed use and Māori purpose zones that already have a main house — no resource consent needed if the standards are met. A companion Building Act exemption removes building consent for a compliant single-storey unit.
The standards that matter: at least 2m from boundaries and from the main house in residential zones (10m front and 5m side and rear in rural zones), total building coverage at or under 50% of the site, and one minor unit per site. District plan hazard overlays and title covenants still apply.

Napier's operative district plan predates the medium-density era, and the city was not required to adopt the MDRS. Its residential zones (Main Residential, Western Hills, and the Westshore, Battery Road and Hardinge Road zones of the Ahuriri subdistrict) each carry their own density provisions, so our screening confirms the zone and the site fundamentals, then routes the density question to a professional check rather than guessing.
For most Napier owners the granny flat standard is therefore the immediately usable pathway, and it is a genuinely new one for this city.
Subdividing a Napier Section
Subdivision minimums for Napier are not yet independently verified into our rule set, so the screening runs the zone, slope, tenure and overlay gates and sends the lot arithmetic to a professional check.
What the Zoning Map Won’t Tell You
Napier's defining constraints are the coast and the plain. Our screening checks tsunami and coastal hazard extents alongside the standard flood and overlay layers, parcel by parcel. Low-lying suburbs and the Ahuriri edge carry real exposure that the zoning map alone will not show you.
Screen Your Napier Address, Free
Everything above is the general picture. Your section's answer depends on its exact zone, parcel geometry, existing buildings, slope, tenure and overlays — which is what our feasibility screening computes live from LINZ parcel data and Napier City Council's own planning layers, with every rule cited to its source. Screening is free and unlimited across granny flats, multiple dwellings and subdivision.
