    Bottom line

    The 2026 exemption helps, but it does not make every backyard automatically buildable.

    Eligible new, standalone, single-storey dwellings up to 70 m² can use the building-consent exemption, but the Building Code, planning requirements, PIM process, professional responsibilities and every exemption condition still matter. Your site also has to work.

    Potential PIM spend

    Save the council fee for a project worth pursuing

    Why risk around $700 before you know the granny flat idea deserves the next step?

    Council fees vary, but some published residential PIM and lodgement charges total around $700—and extra processing can still apply. Start with our free property snapshot, identify the obvious risks first, and spend the larger council fee when the project has a clearer path forward.

    A PIM is still required before construction starts under the granny flat exemption. This early check helps you decide whether you are ready to invest in that formal step.

    Avoid the wrong first spend

    Know what needs checking before you buy plans, a LIM or a kitset.

    The snapshot is not a shortcut around proper due diligence. It helps you put that due diligence in the right order—before a footprint, deposit or design fee narrows your options.

    • See whether 30 m², 50 m² or 70 m² looks realistic for the site.
    • Flag flood, slope, services and planning issues while your options are still open.
    • Learn whether a PIM, property file, survey or specialist review should come next.
    • Avoid treating ‘no building consent’ as ‘no rules, records or professional input’.

    Inside the review

    Six questions the full desktop report helps answer.

    Every property is different. The report turns general granny flat rules into a more useful first decision for your address.

    Size, siting and coverage

    We review the likely building platform, existing development, separation, setbacks and whether a smaller footprint may be the more realistic option.

    Planning and exemption pathway

    We flag zoning, overlays and obvious district-plan risks, then test the idea against the core Schedule 1A characteristics.

    Flood, flow paths and levels

    Mapped flood hazards and overland flow can affect finished-floor height, foundation strategy, drainage and where the building should sit.

    Slope and land hazards

    We identify visible slope, instability or landslide susceptibility that may call for geotechnical advice before plans are locked in.

    Services and drainage

    We review visible public wastewater and stormwater information and flag the private connection questions that still need confirmation.

    The smartest next investigation

    You receive a practical sequence for any PIM, property file, survey, geotechnical, flood or concept work that should follow.

    Evidence from real work

    From desktop risk review to a buildable concept.

    The $97 report is an early filter, not the finished design. If the site looks promising, measured information, accurate siting, plans and elevations turn that direction into a coordinated project.
