Change of Use ( COU) Assitance

---

 Where a building will be used for a different purpose converting a warehouse to offices, a shop to accommodation, or any change in occupancy Change of Use requirements under the Building Act may apply.

C3 Building Compliance provides council-ready support for Change of Use projects across New Zealand, helping property owners, designers, and project teams work through the requirements. These projects often trigger additional Building Code considerations around fire safety, accessibility, structural performance, durability, and means of escape.

Working alongside your project team, we identify the applicable requirements early and give clear guidance through to approval, balancing compliance with buildable outcomes so you avoid redesigns and delays later on.

•  Change of Use assessment — determining whether COU provisions apply to your project

• Building Code review — identifying the affected clauses and compliance requirements

• Council-ready documentation — preparing supporting assessments and reports

• Project coordination — working with designers, consultants, and stakeholders

• Submission support — guiding the application through council review to approval
