Model Subdivision Conditions are used by the WAPC and referral agencies to assist in the consistent application of planning legislation and policies when making decisions on subdivision applications.
The Model Subdivision Conditions Schedule – December 2025, includes updates to several water management and servicing conditions to reflect the requirements of State Planning Policy 2.9 Water (released 18 December 2025).
The schedule is updated regularly with the approval of the WAPC to ensure subdivision conditions are contemporary and that the required outcomes are being achieved. It is expected the model conditions are utilised by all referral agencies. Where an agency considers that a model condition is not appropriate, additional supporting information to justify the use of an amended condition must be provided and the proposed amended condition will need to be assessed for consistency and validity.
