In short
Short answer: the Design and Development Overlay (DDO) is a Victorian planning overlay set out in clause 43.02 of the Victoria Planning Provisions and applied to land through each council's planning scheme. In the clause's own words, its first purpose is: “To identify areas which are affected by specific requirements relating to the design and built form of new development”. (Department of Transport and Planning (Victoria), verified 27 Sep 2026)
An overlay sits on top of the land's zone and adds controls for one issue, whatever the zone is; a lot can carry several.
What it typically means for a buyer (Delora editorial, not legal advice): Sets built-form requirements such as height, setbacks or design, beyond the zone.
Check whether the Design and Development Overlay applies to an address with Address Check. For a decision on a specific property, the official record is a Planning Property Report from VicPlan, and the council's schedule sets the local detail.
