Can you get a Certificate of Acceptance for your unconsented work?
Get a free, site-specific feasibility assessment to find out if a CoA is achievable - before you spend thousands on professional reports and council fees.
Bottom line
A Certificate of Acceptance is the only legal way to regularise post-1992 unconsented building work, but it is not a simple rubber stamp.
The reality is: many CoA applications are delayed, qualified, or refused because applicants underestimate the documentation, professional reports, and remedial work required. Knowing whether a CoA is feasible before you invest is critical.
Why CoA is complex
Why a Certificate of Acceptance is not straightforward.
A Certificate of Acceptance (CoA) is the only legal way to regularise building work done without a building consent after 1 July 1992. But it is not a simple rubber stamp - council must be satisfied the work complies with the Building Code, often without having inspected it during construction.
The CoA process is complex, expensive, and full of technical requirements. We offer free guidance so you understand what is really involved before committing.
Whether you've just discovered unconsented work on a property you're buying, or you need to regularise work for lending purposes - our team explains the process in plain language and helps you decide the right course of action.
Building Code Compliance
Council must be satisfied the work meets the Building Code - often hard to prove after construction.
Invasive Inspections
Council may require opening up walls, floors, or ceilings to verify structural and moisture compliance.
Resource Consent Issues
Unconsented work may also breach district plan rules, requiring separate resource consent.
Cross-Lease & Title Complications
Cross-lease properties need written authorisation from all other leaseholders before applying.
