Do I need this if I already have an owner-builder permit?

The permit lets you manage the build, but does not replace the need for compliance checks. Many lenders and insurers ask for independent stage inspections regardless of your permit status.

Can this consultant also help me sequence trades?

Some do offer light-touch scheduling advice, but the core service is compliance inspection and sign-off, not full project management.

Is this only for full home builds?

No, it's commonly used for granny flats, extensions and renovations run by owner-builders as well as full knockdown-rebuild projects.

Owner-builder supervision and sign-off support for Perth self-managed projects

WA allows owner-builders to manage their own construction under a permit, but most lenders, insurers and councils still want independent verification that the work meets the building code at each stage. This is a completely different engagement from hiring a builder to run the whole job: here, the owner is the one coordinating trades and sequencing, and brings in a consultant specifically to check compliance and sign off on stages.

Typical stages checked include footings and slab before pour, frame before lock-up, waterproofing before tiling, and final completion before occupancy. A consultant working this way for an owner-builder in Perth will also help interpret WA building code requirements the owner-builder permit doesn't automatically explain, and can flag where a licensed trade (electrical, gas, structural steel) is mandatory rather than optional.

This service suits people extending, renovating or building a granny flat themselves who still want a qualified second set of eyes at each stage rather than discovering an issue at final inspection.

What it costs

Usually charged per site visit or as a staged package covering the standard inspection points (footings, frame, waterproofing, final). Cost depends on how many stages you want covered and how far the site is from the metro area. Cheaper than a full construction management contract since you retain the coordination role.
