Can I build a granny flat in Hobsonville?

Check Hobsonville precinct boundaries, stormwater controls and infrastructure for the actual site before relying on growth-area assumptions.

Possibly—but the locality alone cannot determine eligibility. The proposed building and the actual address must pass separate building and planning checks.

Indicative locality result

Gate 1

Building Act

Design check required

The Building Act exemption depends on the proposed building and the people responsible for the work.

Gate 2

Planning rules

Address check required

The NES-DMRU pathway, zone, overlays, precincts and other rules must be checked for the legal site.

Passing one gateway does not prove the other. This locality guide is information, not council approval.

What Hobsonville can—and cannot—tell you

Hobsonville contains several named precincts. Official Plan Change 12 material records transport, urban-design and stormwater provisions for the Hobsonville Corridor Precinct, including Stormwater Management Area: Flow 1 over parts of that precinct.

A precinct provision stops at its mapped boundary. Nearby development and new infrastructure do not prove that a specific title has the same controls or available capacity.

Local checks to make

Start with these Hobsonville checks

  1. 01/

    Precinct boundary

    Identify whether the site is inside a current precinct and which sub-area or provisions apply.

  2. 02/

    Stormwater controls

    Check the current Stormwater Management Area and site-specific discharge or attenuation requirements.

  3. 03/

    Infrastructure and coast

    Confirm services, access, hazards and coastal mapping for the title rather than inferring them from surrounding development.

Why the address changes the answer

A property within a corridor precinct can have different stormwater and access requirements from one just beyond it, even though both are marketed as Hobsonville.
