No law sets a fixed number of weeks for a building approval in Queensland. What the legislation does fix are the periods around the decision: a private certifier who approves your application must give the council a copy of the application and the approval documents within 5 business days (Building Act 1975, s 86(1)(a)); the appeal period after a decision notice is 20 business days (Planning Act 2016, s 229(3)(h)); and the approval lapses if work does not substantially start within 2 years of it taking effect, unless the approval states another period (Planning Act 2016, s 85(1)(c)). The assessment itself runs under the Development Assessment Rules, prescribed by section 44 of the Planning Regulation 2017. A straightforward house, extension or pool that a private certifier can assess on its own moves quickly. The moment the job also needs a planning approval from Noosa Shire Council or Sunshine Coast Council, you are on a longer, staged clock.
Why “building approval” is usually two approvals
A building development approval is assessed against the building assessment provisions, which section 30 of the Building Act 1975 lists as including the Building Code of Australia — the building volumes of the National Construction Code — and the Queensland Development Code. Business Queensland states you can get one “from your local government or a building certifier”, and that one is needed before construction starts on most types of domestic building work. A planning approval is separate, assessed against the Noosa Plan 2020 in Noosa Shire or the Sunshine Coast Planning Scheme 2014 south of that boundary, and needed when your work is assessable development under that scheme.
They stack, they do not run in parallel. The QBCC puts it on you: “It’s your responsibility as a home owner to make sure the right building approvals are in place before work starts — even if you’ve hired a builder.” Your builder should be driving that sequence; ours is set out on our build process page.
Statutory timeframe table by application type
| Application or step | Statutory period | Where it is set |
|---|---|---|
| Building development approval — how long it stays alive | Lapses if the work does not substantially start within 2 years of the approval taking effect, unless a period is stated in the approval | Planning Act 2016, s 85(1)(c) |
| Material change of use approval (for example a dual occupancy or a new use) | Lapses if the first change of use does not happen within 6 years, unless a period is stated in the approval | Planning Act 2016, s 85(1)(a) |
| Reconfiguring a lot (subdivision) | Lapses if the plan of reconfiguration is not given to council within 4 years, unless a period is stated in the approval | Planning Act 2016, s 85(1)(b) |
| Extending a currency period | The extension application must be made before the approval lapses | Planning Act 2016, s 86(1) |
| Code-assessable planning application council does not decide in time | Applicant may give a deemed approval notice; council then has 10 business days to issue a decision notice. Not available where the building assessment provisions are an assessment benchmark | Planning Act 2016, s 64(2)(c), s 64(6) |
| Appeal period after a decision notice | 20 business days after the notice of the decision is given | Planning Act 2016, s 229(3)(h) |
| Approval where someone made a submission | Takes effect the day after the last appeal period ends, or after the last submitter gives notice they will not appeal | Planning Act 2016, s 71(2)(b) |
| Private certifier giving an approved application to council | Within 5 business days of approving the application | Building Act 1975, s 86(1)(a) |
| Residential demolition assessable under a planning instrument | Certifier must not release the approval documents until 5 business days after giving them to council | Building Act 1975, s 88(2B) |
| QDC variation application to the State (relaxing a Queensland Development Code provision) | Decided within 20 business days, or 2 business days where a fast-track request is granted. The assessment process for the related building application stops while it is on foot | Building Act 1975, s 41(4) (20 business days), s 39 (fast track), s 40 (stop); Building Regulation 2021, s 91(3) |
| Council exemption from part of the pool safety standard | 40 business days, plus the days taken to answer a request for further information. Taken to be refused if not decided in that period | Building Act 1975, s 245B(6) and sch 2 (decision period) |
| Public notification for impact-assessable development | Business days exclude every day between 20 December of a year and 5 January of the next | Planning Act 2016, s 53(12) |
| Pool barrier inspection under a pool-only building approval | Inspection day is the earlier of 6 months after the approval is given, or 2 weeks before it lapses (2 years where the approval also covers a class 1 or 2 building) | Building Regulation 2021, s 58 |
What decides whether yours is fast or slow
- Whether a planning approval is triggered at all. Overlays do most of the triggering here — bushfire, flood hazard, coastal hazard and erosion prone land, acid sulfate soils, character provisions. A flat infill block at Cotton Tree and a steep lot at Ninderry are not the same application, even for the same house.
- Whether your siting complies. Queensland Development Code parts 1.1 and 1.2 set the design and siting standards for housing on lots under 450m2 and on lots 450m2 and over. Schedule 7 of the Building Regulation 2021 records the current versions of both as published 3 August 2026 and taking effect 1 September 2026, so older drawings are worth re-checking. If your design does not include an acceptable solution for a relevant performance criterion under those parts, table 3 of schedule 9 to the Planning Regulation 2017 makes your local government a referral agency for design and siting, assessing whether the building complies with that performance criterion. The alternative is a QDC variation application to the State — which, under section 40 of the Building Act 1975, stops the assessment process for the building application while it is on foot.
- Whether the documentation is complete. Sunshine Coast Council’s advice on avoiding assessment delays asks for legible sized plans showing all dimensions, heights and setbacks from boundaries, the overlay reports the assessment forms call for, and reports and plans that do not contain conflicting information.
- Referral agencies. State-controlled roads, tidal works, vegetation or trunk infrastructure add a referral leg outside your certifier’s control.

The council side: Sunshine Coast and Noosa
Sunshine Coast Council publishes a priority residential assessment service for low-risk code-assessable residential applications, including a new dwelling house, secondary dwellings, dual occupancy, up to 10 multiple dwellings and small reconfigurations creating a maximum of two additional lots with no new road. Council states the mandatory pre-submission review is free of charge and expected to take no longer than 10 business days from receipt of the request; a confirmation notice issues within 5 business days of lodgement; any information request issues within 5 business days; you have 10 business days to respond to it; and you can expect a decision within 5 business days for a dwelling house and 10 business days for the other eligible types, where the application is decision ready.
Those are council’s published service levels for a streamlined pathway, not a statutory guarantee. Anything impact assessable, publicly notified or carrying a referral runs the full staged process Sunshine Coast Council describes as the five parts of the Development Assessment Rules: part 1 application, part 2 referral, part 3 information request, part 4 public notification, part 5 decision. Council notes not every application goes through all five. Noosa Shire Council assesses against the Noosa Plan 2020 within that same framework.
Approved does not yet mean you can start
Section 72 of the Planning Act 2016 allows development to start only once every development permit for the development has started to have effect and every condition that must be complied with before development starts has been complied with. Where someone made a submission, section 71(2)(b) delays that effect until the day after the last appeal period ends — 20 business days. Plan your site start around the effective date, not the decision date. After that, the two-year currency period is the clock that matters, and an extension application must be made before the approval lapses, not after.

Frequently asked questions
Is there a legal deadline for a certifier to decide my building approval?
The decision period sits in the Development Assessment Rules, prescribed by section 44 of the Planning Regulation 2017. Note that the deemed approval remedy in section 64 of the Planning Act 2016 does not apply where the building assessment provisions are an assessment benchmark, so a building approval cannot be deemed approved the way some code-assessable planning applications can.
How long does a building approval last in Queensland?
It lapses if the development does not substantially start within 2 years of the approval taking effect, unless a different period is stated in it (Planning Act 2016, s 85(1)(c)). A material change of use approval runs 6 years and a reconfiguring a lot approval 4 years, again unless the approval states a period. You can apply to extend, but only before it lapses (s 86).
Can I start work the day the approval is issued?
Not always. Section 72 of the Planning Act 2016 requires every development permit to have started to have effect and every pre-start condition to be met first. If there was a submitter, the approval does not take effect until the day after the last 20 business day appeal period ends.
Does lodging over Christmas cost me time?
For public notification, yes. Section 53(12) of the Planning Act 2016 provides that a business day does not include a day between 20 December of a year and 5 January of the next year, so a notification period straddling the break runs longer on the calendar.
Does the builder or the owner carry the approval risk?
The QBCC states it is the home owner’s responsibility to make sure the right approvals are in place before work starts, even if you have hired a builder. The QBCC also states building work valued over $3,300 must be carried out by a licensee, and over $1,100 where it involves hydraulic services design.
