Check the rule the site states for your area
Residents read this site before they read the planning scheme. Each council page states the secondary dwelling rule in one line, links the clause it was read from and shows the date. A council that finds a word wrong can have it corrected within one working day, and every change is kept on the record.

The 12 rules pages
One page per South East Queensland council. Each states the size cap, the minimum lot where the scheme sets one, what else the scheme asks (distance from the house, bedrooms, the driveway), who can live in the home, the approvals always needed, and the infrastructure charge where the council publishes one. Every figure links to the page it came from.
Every other Queensland council's cap is on file too, read from its scheme the same way, and feeds the block check. A council outside the 12 that wants its page built can ask below.
How a correction is made
- Email the page and the clause. howdy@bigsmallhaus.au with the page address, the scheme clause or document, and the reading the council says is right. A planning officer's email is enough; no form, no account.
- The rule file is changed and the site rebuilt, within one working day of the email. The page then shows the corrected rule, the new source link and the date it was read.
- The change is kept. Every council rule is recorded each time it is read, append-only, with the previous reading, the source and the date. A correction appears there as a change from the old wording to the new, so anyone can see what the site said before and when it changed.
- The council is told it is live, by reply, with the link. If the council wants its planning contact page linked from the rules page, that link is added at the same time.
The same one working day applies to any fact on the site: a maker's price, a builder's licence, a listing. It is the rule on the makers page too.
Queensland Housing Code adoption tracker
The Queensland Housing Code started on 1 September 2026. It sets state-wide siting rules for houses and secondary dwellings: height, setbacks, privacy, parking, site cover and open space. It applies in a council area only once that council amends its planning scheme to adopt it, and councils have until 1 September 2029. Until then the council's own scheme and the Queensland Development Code siting parts apply. The table shows what was found on each council's scheme page when its rules were last read.

"No adopting amendment found" means the state's Housing Code page named no adopting councils and the council's scheme page listed no amendment adopting the code when the rules were read. "Not adopted" means the council's own amendments page was also checked and lists none. A council that has adopted the code, or has an amendment on exhibition, can have this row changed within one working day of an email. The tracker is rebuilt from the council rule files each quarter for the Small Homes Report.
What councils can use
- A plain-English page to point residents at, one per council, with the clause linked, so an enquiry arrives knowing the cap, the distance rule and the approvals needed.
- The free block check, which reads the zone, lot, overlays and sewer from the council and state maps for any address and shows a home on the lot to scale. The same check a planning counter would do first.
- The numbers. How many homes fit the council's cap and what they cost installed, how many houses for sale in the council have room for a second home, and what a flat rents for by postcode, in the cost index and the quarterly report. Data on request.
- A correction channel that works in one working day, with the change on the record.
Questions
Who wrote the rule on each council page?
The site did, from the council's own planning scheme clause, which each page links with the date it was read. The wording is the site's plain-English summary; the clause is the rule. Where the two differ, the clause wins and the page is corrected.
How is a correction made?
Email the page, the clause and the correct reading to howdy@bigsmallhaus.au. The change goes live within one working day. The old reading and the new one are both kept, with their dates, in the site's rule history, so anyone can see what changed and when.
Can a council ask for its page to come down?
The page can be corrected to anything the scheme supports, and any claim the council disputes is removed while it is checked. The rule itself is public law, so the page that states it stays, with the council's correction and the date.
What does the tracker show?
For each of the 12 South East Queensland councils: whether an amendment adopting the Queensland Housing Code was found on the council's scheme page when it was last checked, and the rule that applies until one is. Councils have until 1 September 2029.
Does the site advise on applications?
No. It states the rule and shows what fits a block. Every page says a building approval from a certifier and a plumbing approval from council are always needed, and sends people to the council for anything the scheme does not answer.
