    Do I need building consent for this project?

    Homeowners usually start with a practical question: can I do this, and does council need to approve it? The answer depends on scope, site conditions and Building Code risk.

    Bottom line

    Consent need depends on what changes, not just the project name.

    A bathroom, deck, sleepout or renovation can be exempt, consented or risky depending on structure, plumbing, drainage, fire, moisture, height, boundaries and planning rules.

    We identify whether the project may be exempt, consented, planning-triggered or better handled elsewhere.

    3

    Map the risk

    We look for Schedule 1 limits, zoning constraints, overlays, site risks and consultant requirements.

    FAQs

    Questions homeowners ask first.

    Can you answer without drawings?+

    Often we can give an early pathway view from the address, description, photos and rough dimensions. Detailed design comes later if the project proceeds.

    Should I check feasibility before builder quotes?+

    Yes, especially if you are unsure whether the project is exempt, needs consent, triggers planning issues or requires consultants. Early clarity can prevent inaccurate pricing and redesign.

    What happens after feasibility?+

    The next step may be fixed-fee design, building consent documentation, council support, CoA support, planning advice or a specialist report depending on the pathway.

    Is feasibility the same as full design?+

    No. Feasibility identifies the likely pathway, risks and next step. Full design and consent documentation come after the scope is clearer.
