Melbourne ADU Permits & Bylaw Guide

Housing and Building Standards Victoria 4 Minutes Read · published February 11, 2026 Flag of Victoria

Building an accessory dwelling unit (ADU) in Melbourne, Victoria involves both planning and building approvals from local and state authorities. This guide explains when a planning permit and a building permit may be needed, who enforces rules, how to apply, and practical steps to reduce delays. It summarises the City of Melbourne planning process, the state planning scheme context and building-permit requirements so owners and builders can prepare correct documentation, lodge applications and address enforcement or appeals efficiently.[1]

Check whether your site is in a heritage overlay or special zone early in design.

Planning vs Building Permits

Most ADUs involve two separate approvals: a planning permit under the relevant planning scheme and a building permit under the Building Act and regulations. Use the City of Melbourne planning resources for local permit triggers and the Victorian Building Authority for building-permit procedures.[1][3]

  • Planning permit: required where the local planning scheme or overlay specifies a permit trigger.
  • Building permit: required for structural work, plumbing, drainage and most new habitable spaces.
  • Vegetation, heritage and setback rules may create additional consent needs; check the local planning scheme.

Penalties & Enforcement

Enforcement for unauthorised ADUs in Melbourne is managed through local compliance processes and may escalate to legal action; specific fine amounts or penalty units are not specified on the cited City of Melbourne planning pages. For planning scheme breaches, the state planning and building framework also provides enforcement pathways and appeal venues.[1][2]

  • Fine amounts: not specified on the cited page.
  • Escalation: first notices, enforcement notices and potential court proceedings are referenced; exact escalation bands are not specified on the cited page.
  • Non-monetary sanctions: enforcement notices, stop-work directions and orders or prosecution may be used.
  • Enforcer: City of Melbourne planning and compliance teams handle inspections and complaints; official contact channels are provided on the council site.[1]
  • Appeals: planning permit refusals and enforcement orders are typically appealed to the Victorian Civil and Administrative Tribunal (VCAT); check the planning scheme references for time limits, or see the state planning site for procedures.[2]
Record decisions, permits and correspondence to support any appeal within prescribed timeframes.

Applications & Forms

City of Melbourne provides application guidance and checklists for planning permits; the Victorian Building Authority publishes building-permit and certificate requirements. Fees for planning and building applications vary by project and are set in fee schedules; if a specific fee is needed consult the cited pages or contact the responsible office.[1][3]

  • Planning application: use the City of Melbourne planning permit application process and checklist.
  • Building permit: engage a registered practitioner and lodge the building permit with a registered building surveyor per VBA guidance.
  • Fees: not specified on the cited pages; refer to the council fee schedule and VBA fee information.
If unsure whether a permit is required, request pre-application advice from the council.

  • Step 5: Pay any fees, respond to requests for more information and arrange inspections as required.
