Perth, Western Australia builders must follow state and local planning controls when subdividing land. This guide explains typical minimum lot-size drivers, approval pathways, and practical steps from pre-application advice through lodgement and plan registration. It summarises who enforces rules, common compliance risks, and where to find official application forms and plan lodgement guidance for Perth subdivisions.

Talk to the local planning officer early — it can save weeks in the approval process.

Lot size controls and planning context

Lot sizes in Perth are set by a combination of the Metropolitan Region Scheme, local planning schemes, and WAPC subdivision conditions. Minimum lot sizes or density codes are recorded in the applicable local planning scheme or structure plan and enforced at subdivision approval. For guidance on the subdivision approval pathway and state requirements, consult the Department of Planning, Lands and Heritage subdivision information Department of Planning, Lands and Heritage - Subdivision[1].

Typical subdivision steps for builders

Builders and developers usually follow these stages: initial feasibility and service availability checks, prepare survey and engineering design, lodge a subdivision application, satisfy conditions, complete works, and register the deposited plan with Landgate.

  1. Pre-application meeting with local council and/or WAPC to confirm scheme requirements and constraints.
  2. Engage a licensed surveyor to prepare a scheme-compliant proposal and engineering drawings for services.
  3. Lodge the subdivision application with the WAPC/department and pay any application fees.
  4. Complete any required civil works and infrastructure upgrades to satisfy conditions of approval.
  5. Obtain the certificate of compliance and prepare the deposited plan for lodgement with Landgate.

Penalties & Enforcement

Enforcement of subdivision and development controls is carried out by the approving authority (WAPC/Department) and local government compliance officers. Specific monetary penalties for unlawful subdivisions or failure to comply are not universally listed on the cited pages; see the local enforcement contacts for particulars City of Perth Planning & Compliance[2].

What to expect from enforcement actions:

  • Fine amounts: not specified on the cited page.
  • Escalation: first, repeat and continuing offence processes are not specified on the cited page.
  • Non-monetary sanctions: orders to remedy, stop-work directions, conditions requiring rectification, and court action are available remedies under planning and local government powers.
  • Enforcer: Planning and Development officers, local government compliance teams, and the WAPC for subdivision approvals.
  • Inspection and complaint pathway: contact local council compliance or the planning approvals contact listed by the council or the Department.
  • Appeal/review: review or appeal routes commonly involve the State Administrative Tribunal; time limits and procedures should be confirmed on the approving authority guidance.
If you receive a compliance notice, act promptly and seek written clarification of the required remedial steps.

Applications & Forms

Subdivision applications and plan registration require official forms and lodgement steps: the Department/WAPC handles subdivision approvals and provides application guidance; deposited plan lodgement and title registration are processed by Landgate. For plan registration, see Landgate guidance on deposited plans Landgate - Plan Registration[3]. If a specific application form or fee is required, the approving authority or Landgate pages list the current form names and submission methods; where a fee or exact form number is not shown on those pages, it is not specified on the cited page.
