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.
