When building close to a boundary, a HIRB (Height in Relation to Boundary) survey ensures your design complies with local height regulations. Our licensed surveyors provide the certificates needed for council submissions and Code of Compliance (CoC). We also assist with inspection surveys and resolve disputes with local authorities. Every document we produce is accurate, council-ready, and backed by professional standards.
