Hawkesbury Rural Dual Occupancy Rules Slip to Late 2026 Exhibition
Hawkesbury City Council will miss its August 2026 target for rural detached dual occupancy rules, with public exhibition now expected between 28 September and 30 October after a planning extension to 21 December. For Hawkesbury dual occupancy delay 2026, Updated 2 July 2026.
The Hawkesbury Gazette quoted director of city planning Monica Cologna saying council incorporated draft Sydney Plan shifts and March 2026 parliamentary inquiry findings into a revised planning proposal awaiting Department endorsement.
Rural landowners waiting to house family on one title face another quarter of uncertainty.
Why the timeline moved
Council originally aimed to complete the planning proposal by August 2026. Department of Planning, Housing and Infrastructure is expected to approve an extension to 21 December 2026. Exhibition cannot start until the revised proposal is endorsed.
Inquiry recommendations on second dwellings in rural areas are now embedded in the draft, but state government formal response landed 30 June, adding alignment work.
What residents were hoping to build
Detached dual occupancies on rural land would let families host adult children or ageing parents without subdivision. Hawkesbury evidence to the inquiry highlighted multi-generational demand on acreage lots west of Sydney.

Planning alongside airport-zone rules
Western Sydney airport granny flat changes do not replace Hawkesbury rural policy. Noise contours and RU zoning still dominate feasibility on many lots. Read airport noise contours explained if your property sits near flight paths.
What to do while waiting
Prepare concept sketches, bushfire assessments, and access driveways for consultation feedback once exhibition opens. Verify certifier availability early; rush periods follow every NSW policy launch.
Rural landowners can still lodge pre-lodgement meetings with council planners to test whether current secondary dwelling rules allow a smaller compliant unit on their lot. That path does not depend on the delayed dual occupancy package, though size caps and bushfire APZ setbacks still apply under today’s LEP controls.
Document power and water capacity at the paddock shed site now. Exhibition submissions that include services evidence tend to get faster planner feedback when the revised proposal opens for comment in September 2026.
