Owner Builder – Occupation Information

Introduction

An Owner Builder is an individual who takes responsibility for managing and carrying out construction or renovation work on their own property.

Instead of hiring a licensed builder to oversee the entire project, the owner builder coordinates trades, manages timelines, controls costs, and ensures compliance with building regulations.

This pathway is commonly chosen for home construction, extensions, renovations, or major structural work, allowing greater control over the project.

However, owner builders must meet specific legal requirements, approvals, and responsibilities before starting any work.
