ArchSolutioNZ Building Consent Specialists

    Buying or selling a house with unconsented work.

    Property transactions create urgency. We help identify what the issue appears to be, what evidence exists and what pathway may reduce uncertainty before settlement decisions become harder.

    Bottom line

    Property-sale pressure needs technical clarity, not panic paperwork.

    A CoA may be one pathway, but sale issues can also involve CCC records, planning constraints, legal advice, lending or insurance. We focus on the building documentation and council pathway.

    Process

    A practical path through this CoA issue.

    1

    Review records

    We review photos, property file information, LIM notes, owner details, invoices, drawings or council correspondence.

    2

    Define the scope

    We separate what appears to be covered by the CoA question from work that may belong on another pathway.

    3

    Identify evidence gaps

    We identify likely as-built drawings, specialist reports, photos, opening-up or product evidence that may be needed.

    4

    Prepare next steps

    We help organise the documentation pathway before you spend money on the wrong report or application.

    FAQs

    Questions homeowners ask first.

    Can council accept all completed work through a CoA?+

    No. Council can only assess what can reasonably be verified after the work is complete. Hidden work may need opening up, specialist reports, remedial work or may be excluded.

    Is a CoA the same as a building consent?+

    No. A building consent is for proposed work before construction. A Certificate of Acceptance is a limited pathway for certain completed work that was carried out without the required consent.

    What should I send first?+

    Send photos, your address, a short description of the work, any council letters, LIM notes, property file information, invoices, drawings or reports you already have.

    Can you tell me whether to buy the property?+

    No. We can help explain the building and council documentation issues. Purchase decisions, legal risk, lending and insurance advice should come from the relevant professionals.
