First-pass signals
What we check first
The obvious signals that decide most granny flat block checks. We use public-data checks where available.
Zoning
Lot size
Heritage
Bushfire
Flood / stormwater flags
Site fit from maps
Nearby constraints
Obvious next-step risks
Some items, like sewer diagrams, easements, formal flood advice and certifier decisions, may still need paid or professional review. The block check tells you which ones matter for your property.
Questions
Granny flat block check FAQs
Does this replace council or a certifier?
No. It gives a first-pass yes / maybe / no view from public data and visible red flags. The formal decision comes from a certifier, council or planner, depending on your pathway.
Is the granny flat block check free?
Yes, the block check is free while we are testing the tool. No card, no obligation.
Do granny flat rules change across NSW?
Yes. Granny flat rules in NSW depend on your zone, lot size and council, and some blocks carry extra constraints like flood, bushfire or heritage. The block check flags the obvious ones so you know where to look.
What states do you cover?
NSW first. If the property is outside NSW, we may still review it or tell you if we cannot complete a useful check yet.
Will you sell my details to builders?
No. If you ask for an introduction or agree to be contacted about next steps, we may follow up. We keep consent explicit.
How long does it take?
We review your property and email your block check, usually within 1–2 business days during the test.
Should I still speak to a builder or certifier?
Yes. The check helps you understand whether the block looks worth pursuing and what to ask next. It does not replace a builder, certifier or planner.
