Accessory Dwelling Permits - Brisbane Bylaws

Housing and Building Standards Queensland 3 Minutes Read · published February 11, 2026 Flag of Queensland

In Brisbane, Queensland, adding an accessory dwelling unit (ADU) — sometimes called a secondary dwelling or granny flat — usually requires planning and building approvals from Brisbane City Council. This guide explains where to check local planning rules, what approvals may be needed, how compliance and enforcement work, and the practical steps to apply so you can plan with confidence in Brisbane.

Penalties & Enforcement

Enforcement of breaches relating to accessory dwellings is handled by Brisbane City Council’s compliance and planning teams; specific local controls are set out in Council planning guidance and application pages [1][2]. Monetary penalties and infringement notices for breaches vary by instrument and are not consistently itemised on the general guidance pages, so where exact fines or penalty units are required they are "not specified on the cited page" and must be confirmed on the specific local law or compliance notice referenced by Council.

  • Typical monetary penalties: not specified on the cited page; Council may issue infringement notices or seek orders in court.
  • Escalation: first offences may attract warnings, then fines or orders for repeat or continuing offences; exact ranges are not specified on the cited page.
  • Non-monetary sanctions: compliance or demolition orders, stop-work orders, or court action are possible where unauthorised works or unlawful occupation occur.
  • Inspection and complaint pathways: report suspected unlawful works or non-compliance via Council’s report/complaint channels and Planning and Building contacts [3].
  • Appeals and review: decisions on development approvals and enforcement notices may be reviewable; time limits and appeal routes depend on the decision instrument and are not uniformly listed on the general guidance pages.
If you receive a compliance notice, act promptly because time limits for appeals or compliance directions can be short.

Applications & Forms

Most ADU proposals require either a building approval, a development application (material change of use), or both, depending on zoning, site constraints and whether the dwelling is new or an alteration; Council guidance on secondary dwellings explains common triggers and standards [1]. Specific form names, application numbers and published fees for ADU development are provided on Council’s building and application pages; where a specific fee or form number is needed it is "not specified on the cited page" and applicants should consult the building approval and DA lodgement pages [2].

  • Typical forms: building approval application and development application (if required) — check Council lodgement portals for current forms.
  • Fees: application and assessment fees apply; amounts vary by application type and are published on Council’s fees pages or detailed on the specific application form [2].
  • Deadlines: timeframes for assessment and statutory decision periods depend on the application type and are set out in Council process information; exact statutory time limits should be confirmed on the relevant application page.

Before You Apply

Start by confirming your property’s zoning, overlays, and any neighborhood plan constraints that impact ADUs. Where relevant, confirm service connections, minimum lot sizes, setbacks, site cover and parking requirements in the Council planning guidance [1].

A pre-lodgement meeting with Council planners or a private certifier can identify likely issues early in the project.
