Retrospective Building Approvals

Retrospective building approvals, sorted.
A retrospective (or as-built) approval is the formal certification for structures built without prior approval. Think decks and verandahs, carports and patios, sheds and garages, granny flats and secondary dwellings, pools and retaining walls, or even larger works like dwelling extensions, roof replacements, underpinning and garage conversions.
With new disclosure laws kicking in from August 2025, sellers in Queensland will be required to declare any unapproved works. That’s where Buildcert steps in. We help homeowners, builders, and agents navigate the approval process smoothly. That means no legal jargon, no wasted time and no costly surprises.
We tell you upfront if it’s approvable, handle the legwork, and help you protect your property’s value. Not bad, eh?

How we get your Retrospective Building Approval sorted.
01
Site Visit & AssessmentWe’ll visit your property to inspect the unapproved structure, whether it’s a deck, carport, shed, patio, or granny flat, and check if it can meet the required standards. We review your site against the Building Code and council regulations, and let you know straight away if approval’s achievable. If we can’t approve it, we’ll let you know upfront, no wasted time or costs.
From 1 August 2025, QLD sellers must disclose any unapproved structures. Without formal approval, you risk delays in selling, reduced property value, or legal issues. This step gives you a clear picture early so you can make informed decisions.
A clear, confident path forward. You’ll know exactly where you stand, what’s possible, and how to get there; without stress or guesswork.

What is a retrospective (as-built) building approval?
It’s a building approval that’s issued after the work has already been completed. The certifier reviews plans, engineering, and reports to confirm whether the building or structure meets the National Construction Code and QLD legislation. If it complies, a building approval can be issued so the work is legally recognised.
