Before assessing an RZ1 Suburban zone property in the Australian Capital Territory (ACT), key planning documents to review include the Territory Plan (Residential Zones Policy), the Residential Zones Technical Specifications, and the property's Crown Lease.

Detailed Explanation

Before assessing a development proposal on an RZ1 (Suburban Zone) property in the ACT, the relevant planning documents should be reviewed to identify all applicable planning requirements.

The core planning documents are:

  • Territory Plan 2023 (including the relevant District Policy and Part E1 – Residential Zones Policy): Sets out the planning outcomes, desired neighbourhood character, and assessment requirements for development in the RZ1 zone.
  • Planning (Residential Zones) Technical Specifications 2026 (NI2026-303): Provides the detailed technical standards used to assess residential development, including requirements for setbacks, site coverage, building height, private open space, landscaping, tree planting, parking, and other design controls.
  • Crown Lease and Lease Purpose Clause: Specifies the permitted land use for the property, along with any lease conditions, covenants, or restrictions that may affect what can be developed on the site.

Reviewing these documents together helps identify the planning controls and development requirements that apply to the proposed RZ1 development.

Key Point

No minimum block size does not remove the need for planning assessment.
