ACT Guide
Planning approvals overview (ACT)
Many ACT projects require planning-related approval before your certifier can finalise building approval. This is one of the most common “hidden timeline” risks for owner-builders.
General information only (not legal advice). Always confirm your project pathway with the relevant ACT authority and your certifier.
What to do first (practical path)
- Describe your scope clearly: new build, extension, structural reno, deck, secondary dwelling, etc.
- Ask early whether planning approval applies to your proposal (don’t assume “minor works” are exempt).
- Get it in writing where possible (email confirmation can save you later disputes and redesign loops).
- Align design documents (plans, siting, reports) to the pathway you’re told applies.
- Only then finalise building approval documentation with your certifier.
How planning connects to building approval
Think of planning as a “gate” that can change your design (setbacks, height, site coverage, heritage, trees, overlays). Building approval then checks building compliance (structural, fire safety, energy efficiency, etc).
Planning-related questions (examples)
- Does my proposal require planning approval?
- Are there constraints on my block (heritage, overlays)?
- What setbacks / height rules apply?
- Do trees / verge / easements affect this?
Building compliance questions (examples)
- Does the design meet NCC requirements?
- What engineering is required?
- What energy / glazing evidence is needed?
- What inspections must occur?
Tip
If planning changes your design later, it can invalidate work you’ve already paid for (engineering, energy reports, drawings).
Confirm pathway before you over-invest.
Common mistakes (and how to avoid them)
Assuming “no planning” because it’s a renovation
Extensions, structural changes and site constraints can trigger approvals even when it’s not a new build.
Paying for full drawings before confirming pathway
If planning requires design changes, you can pay twice for documentation.
No written confirmation
A quick email response can be a lifesaver when questions arise later.
Treating planning + building as the same thing
They’re different checks. Planning outcomes often shape what your certifier can approve.
