What supporting reports might ACT Planning request?
It depends on the site and the issues raised by the proposed dual occupancy. ACT Planning may request additional reports or information where needed to properly assess the DA. The current Minimum DA Documentation Guideline specifically states that its checklist is not comprehensive and that the Territory Planning Authority may request additional information.
Depending on the property and proposal, supporting information may relate to matters such as site contamination, traffic or vehicle access, trees and landscaping, heritage, environmental impacts, stormwater or other site-specific constraints. The exact reports required will depend on the characteristics and potential impacts of the development.

Short Answer
It depends on the site and proposal. ACT Planning can request additional specialist reports or information where needed to assess a dual occupancy, including reports addressing site-specific planning, environmental, access, heritage or other technical issues.
Detailed Explanation
The Territory Planning Authority may require additional supporting information where necessary to assess a dual-occupancy DA. The Planning (Minimum Development Application Documentation) Guideline 2026 (NI2026-13) expressly provides that the minimum-documentation checklist is not a comprehensive list of all documentation required for development assessment, and that the Authority may request additional plans or information.
Accordingly, specialist reports may be required where relevant to the proposal or site, including reports addressing contamination, traffic/access, environmental, heritage, landscape/tree, servicing or other technical matters. ACT Planning may also seek further information during assessment, and the application may undergo further entity referral as a result.
No minimum block size does not remove the need for planning assessment.
