LEP (Local Environmental Plan)
The Local Environmental Plan — the NSW council planning law that decides what you can legally build on a block. It sets the zone, the land-use table (permitted, permitted-with-consent or prohibited) and the key standards like height and floor space ratio. If the LEP prohibits a use in your zone, no design cleverness gets around it — check it before you offer.
A Local Environmental Plan (LEP) is the planning law a NSW council makes to control development in its area. It is the single most important document to check before you buy a block to flip, because it decides what you can legally build — and if a strategy isn't permitted, nothing else in your feasibility matters.
Most NSW councils write their LEP off the same Standard Instrument template, so the structure is consistent: the LEP maps every parcel to a zone, and the zone drives the land-use table — the list of what is permitted without consent, permitted with consent, or prohibited. It also sets the core development standards a flipper cares about, chiefly maximum building height and floor space ratio, plus minimum lot size for subdivision. Crucially, an LEP is law: if it says a use is prohibited in your zone, it's prohibited, and no clever design gets you around it.
LEP, DCP and SEPP together
The LEP doesn't work alone. Underneath it sits the DCP — design guidance that shapes how a permitted development has to look but can't make a prohibited use permissible. Above it sits the State Environmental Planning Policy (SEPP) — state rules that apply across council boundaries and can override a local LEP. That last point creates real edges for flippers: the Low and Mid-Rise Housing reforms, for instance, widened what's permitted in low-density zones (Stage 2 commenced 28 February 2025), so a SEPP can unlock a dual occupancy on a block whose local LEP hasn't caught up. When you assess a site, read the SEPP and the LEP together, because the thresholds — lot size, frontage, height, floor space ratio — decide whether your specific block qualifies.
The practical routine is to check the LEP first as a go/no-go, then the overlays and the DCP. How to read a council LEP and its overlays walks through it map by map, and a full deal analysis pulls the zoning and overlay data for an address into one place. General information only, not planning advice — LEP zones and controls vary by council and are updated over time.
