Short answer: there is no national building permit search in Australia. A council, private surveyor or certifier issues the permit under state law, and the record stays with the authority that received it. You search a council register, a state portal or a paid council product, one jurisdiction at a time. Registers key on lot and plan, not street address, and several publish as monthly lists or open datasets rather than search boxes. A record proves a building permit application was made and decided — not that the building complies.
Key Takeaways
- No national register exists. Every official route resolves to a council, permit authority or state portal. Planning trackers cover development applications, not permits.
- The address is the entry point, not the key. Brisbane will not accept a building search without the lot on plan number.
- Access type varies more than coverage. Online registers, monthly PDF lists, open datasets, paid extracts, and in the NT a file released only to the owner.
- A record shows a permit existed. Not that the work complies or that other structures were approved.
- A nil result is not a finding. Archives, portal cut-offs, private certification and boundary changes create gaps.
- Search has a lead time. A 10-day council search does not fit a 7-day inspection window.
Before You Search: Identify the Property, Not Just the Address
"12 Smith Street" exists in dozens of suburbs. Blocks get renumbered. Subdivision splits one address into four. Registers are built around the lot on plan, the parcel identifier on title or survey plan.
Brisbane makes it mandatory: you must supply the lot on plan number to lodge a search (Brisbane City Council, retrieved 23 October 2026). Elsewhere the address may work, but the record is keyed on the parcel. Decoding lot and plan identifiers explains the formats; the number appears on the rates notice or title search.
Search the council that issued the permit, not necessarily the one the property sits in today — amalgamations moved records. That is also why privately certified work appears in a council register: in Victoria, s 30 of the Building Act 1993 (Vic) requires the relevant building surveyor to give the council copies of the permit and lodged documents (AustLII, retrieved 23 October 2026).
Where a Building Permit Search Actually Runs, by State
Each state built its own instrument; several publish no building approvals at all.
| State / territory | What is searchable | Where it runs | Access type |
|---|---|---|---|
| VIC | Council building permit registers (Building Act 1993 s 31) | Individual council registers; City of Melbourne on DataVic | Free register, dataset, paid documents |
| NSW | DAs via the Planning Portal; building records via council | NSW Planning Portal; council | Online (DAs only), paid certificate |
| QLD | Building approvals, final certification, property notices | Council building search — Brisbane is the largest | Paid extract, fixed fees |
| WA | Permits, approval certificates, building orders (Building Act 2011 s 128–129) | Permit authority, published council by council | Monthly PDF lists |
| SA | Development applications, including building consent | PlanSA register | Online, with coverage limits |
| ACT | Primarily development applications | Public register; full register at the Shopfront | Free inspection, charged copies |
| TAS | Planning, building and plumbing enquiries | PlanBuild Tasmania; CBOS administers the Act | No verified public permit register |
| NT | Building files: permits, inspections, plans | NT Government building file access | Owner only, or authorised agent |
Three States, Three Different Products
Victoria implements the same duty very differently. Greater Dandenong publishes permit number, date, surveyor number, address, works description, occupancy permit reference and estimated cost (Greater Dandenong, retrieved 23 October 2026). Geelong covers permits given to council in the last 10 years (Geelong); Melbourne's register is an open dataset on DataVic. But regulation 50 restricts permit documents to the owner, mortgagee or agent, and Port Phillip charges a non-refundable fee even when nothing is found (Port Phillip). The permit exists publicly; the file usually does not.
New South Wales separates the records. The Application Tracker searches development applications (the NSW tracker); building records sit with council. For suspected unauthorised work the instrument is a building information certificate, shielding the building from council action for 7 years (Service NSW, 13 May 2025).
Queensland sells the search as a product. Brisbane lists approvals back to 1946 plus final certification and property notices, at $106.55 for 10 business days or $218.80 for 3 (Brisbane).
Which Registers Are Partial, Offline or Dataset-Only
Western Australia has the clearest statutory duty and the least usable interface. Section 128 of the Building Act 2011 requires a register of permits, approval certificates and building orders; section 129 requires public inspection. The City of Vincent delivers one list per month (City of Vincent).
South Australia has a development register, not a permit index, because building consent sits inside the development approval. PlanSA warns that not all applications are published, pre-31 July 2020 applications may sit in a council register, and the map can miss manual addresses and recent land divisions (PlanSA).
ACT is "primarily for development applications", browsable online, with the full register at Access Canberra's Shopfront (ACT Planning). Tasmania runs PlanBuild Tasmania as its planning, building and plumbing portal, with CBOS administering the Act but not assessing applications (State Planning Tasmania); we could not verify a searchable Tasmanian permit register and do not imply one exists. The Northern Territory has none either: building files go to the owner or a third party with signed authority (NT Government).
Before treating a nil result as a finding, rule out pre-computer records, portal cut-offs, privately certified work lodged elsewhere, and boundary changes.
What a Permit Record Shows, and What It Does Not Prove
A record typically carries the permit number and council reference, the approval date, a description of works, the status where published, the surveyor's registration number, an occupancy permit or final inspection reference, and sometimes estimated cost.
The gaps are larger. A record does not prove the work complies: a permit authorises work on plans, and whether the finished structure matches them needs an inspection. It does not prove conditions were met or mandatory stages inspected. It does not prove final approval, because a permit can be issued and never finalised. It does not prove all work on site is approved: a 1998 permit says nothing about the 2019 pergola. It does not establish ownership. It does not prove planning consent — planning approval is a separate instrument — and what a permit costs is a separate record again.
Absence of a record is not proof no permit exists. Councils hold pre-system records, index under former addresses, and receive privately certified documents on a seven-day lodgement rule that occasionally leaves gaps.
Using a Building Permit Search for Due Diligence
Before buying, match approvals to the structures on the land. Recurring unapproved items are sheds, pools and pool fences, carports, deck enclosures, converted garages and granny flats. A record for the house with nothing for the 2010 extension is not proof the extension is unauthorised; it is a question for the contract, priced as a risk.
Before renovating, design over what is approved; a new application can be refused or conditioned because existing work is unapproved. Lead time bites: a council search quoted at up to 10 days, as described in a PropertyChat thread on unapproved structures, does not fit a 7-day inspection window.
When a Record Search Is the Wrong Instrument
A search returns records; a certificate returns a position. In NSW the choice is between the free Planning Portal property report and a section 10.7 planning certificate, and they are not interchangeable — the property report versus a section 10.7 certificate sets out which is mandatory on sale. Victoria's equivalent is a building information certificate on sale, separate from a property information certificate used at design stage (Frankston).
A nil result and an in-progress application look identical on a register publishing only decisions. Check the expected issue period first — how long a building permit takes sets out the periods state by state.
For a South Australian address, run a free site check to see which approval pathway the site is likely to take. That is a site and pathway screen, not a permit-record search; neither Cyberate PM nor DDDI can search permit history for you.
Cyberate Project Management (CPM) is part of DDDI Group, which publishes this article. Links to CPM are related-party referrals, not independent recommendations. CPM provides development approval and subdivision management in South Australia only; approval rules, fees and services differ in other states.
Licence Checks Are a Different Search
A permit register tells you about work, not whether the person who did it is licensed, insured or still trading; those records sit with state licensing regulators under different legislation. A permit number is not a licence number. For the trade side, see licence and insurance checks on trades.
Frequently Asked Questions
Is there a national building permit search in Australia?
No. Councils, private building surveyors and certifiers issue permits under state and territory legislation, and no national register consolidates them. Third-party sites such as PlanningAlerts track development applications, not building permits.
Can I search building permits by address?
Usually, but the address is the entry point, not the key. Many registers index on lot and plan, and Brisbane requires that number before accepting a search. Get lot and plan from the title or rates notice first, then search the council that issued the permit.
Does a permit record prove the work was done properly?
No. It proves a permit was applied for and decided. It does not show the completed work matches approved plans, that conditions were met, that mandatory inspections occurred, or that a final inspection or occupancy permit issued.
How far back do building permit records go?
It varies. Brisbane's records go back to 1946, Geelong's online register covers the last 10 years, and Port Phillip states its records generally extend to the 1960s.
Does a building permit record show planning approval?
No. Planning and building approval are separate instruments with separate decision-makers. In SA building consent sits inside the development approval; in NSW the Planning Portal tracks DAs while building records sit with council.
What the Record Is For
A permit record is one piece of evidence, not a clearance. Use it to establish what was approved and when, then pair it with the certificate appropriate to the state and an inspection of the structure that exists. Where the record is silent, the answer is usually a certificate or a file request — not an assumption in either direction.
