In short
Short answer: the Incorporated Plan Overlay (IPO) is a Victorian planning overlay set out in clause 43.03 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 require: the form and conditions of future use and development to be shown on an incorporated plan before a permit can be granted to use or develop the land; a planning scheme amendment before the incorporated plan can be changed”. (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): Development must follow an incorporated plan for the area.
