Can agricultural land be rezoned for housing in Ireland?

Rezoning is a policy decision made through the statutory development plan process under the Planning and Development Act 2000, not something an individual landowner can obtain through a planning application. A council reviews and re-adopts its full development plan roughly every six years (or amends it through a formal 'variation'), and it is during that process — not at any other time — that zoning maps can be changed.

During a plan review, any member of the public, including a landowner, can make a written submission requesting that a specific parcel be rezoned from agricultural to residential (or another use). The planning authority's executive assesses submissions against the settlement strategy, core strategy population and housing land requirements set by the National Planning Framework and the relevant Regional Spatial and Economic Strategy, along with infrastructure capacity, flood risk and environmental considerations. Elected councillors then vote on whether to accept or reject proposed zonings as part of adopting the plan.

Rezonings are also subject to strategic environmental assessment and appropriate assessment requirements, and core strategy rules mean a council generally cannot zone more land for housing than its assessed population and housing targets justify — so even a well-argued case for a particular field can be rejected if the county's overall zoned land supply is already sufficient.
