Approvals and timeframes

This page provides an overview of the approvals required before commencing works and the associated timeframes.

Prior to commencing any works and/or use within the Town, development (planning) approval and a building permit is required unless the proposed development and/or use is exempt. Depending on the circumstances, approval from a State Government department (e.g. the Department of Planning, Lands & Heritage on behalf of the Western Australian Planning Commission) may be required.

Requirement for planning approval

Currently, Local Planning Scheme No. 3 (LPS 3) controls the development and use of land across the Town of Mosman Park.

Planning approval ensures that a proposed development and/or use complies with the relevant Local Planning Scheme, Residential Design Codes (R-Codes), Local Planning Policies and any other relevant legislations and policies.

For example, the following works and/or uses require planning approval:

  • building a single house, grouped dwellings or multiple dwellings
  • extending or altering an existing building (including sheds, patios, garages, carports and solar panels)
  • building a replacement structure (for example, an old patio is being dismantled and another patio is being built as a replacement)
  • changing the use of the subject property
  • signage
  • conducting business from home.

Proposed works and/or uses that meet an applicable exemption and all associated requirements will not require planning approval.

How long does the Town have to approve my planning application?

The Town has 60 calendar days after lodgement to determine non advertised applications and 90 days after lodgement for advertised applications (the timeframes do not include days where the application is placed on hold). The Town endeavours to assess and determine planning applications in a timely manner, and in many cases determines applications well before the required statutory timeframes.

Requirement for building approval

Regardless of whether planning approval is required, a building permit is still required for most residential, commercial and industrial works, including but not limited to:

  • new works
  • alterations and additions
  • patios, sheds and shade sails
  • swimming pools and spas (including pool safety barriers or fences for pools and spas)
  • commercial fit outs.

Where planning approval is required, a building permit cannot be applied for or issued before planning approval is granted.

How long does the Town have to approve my building permit application?

The time to approve an application depends on the type of application made.

  • An uncertified application must be determined within 25 business days.
  • A certified application must be determined within 10 business days.

Should further information be requested by the Town for an application to be considered complete, the time period for this further information to lodge is then deducted from the required time frames.
