Do I need planning permission for a mobile home on my land in Ireland?

Usually yes, if someone will live in it. Placing a mobile home on land for use as a dwelling is normally a material change of use of that land and requires planning permission, even though a caravan simply stored in the garden of an existing house can be incidental to the enjoyment of the house.

Planning control in Ireland applies to the use of land as well as to building work. Under the Planning and Development Act 2000, development includes a material change in the use of land, so bringing a mobile home onto a site and living in it generally requires planning permission — the structure being movable does not remove the need.

A caravan or mobile home parked and stored in the garden of a house, unoccupied and incidental to the enjoyment of that house, is a different situation and is commonly treated as not requiring permission. The moment it becomes accommodation, that reasoning no longer applies.

Local authorities also see short-term temporary cases — for example, accommodation on site while a permitted house is being built. These are handled case by case and often through a temporary permission rather than an exemption, so they should be agreed with the planning authority in advance.

What the council will look at

Expect these questions:

  • Will anyone live in the mobile home, and for how long?
  • Is the land already a house site, or agricultural or undeveloped land?
  • How will wastewater and water supply be provided?
  • Is there an existing permission on the site that the mobile home relates to?
  • Does the county development plan restrict residential use of the land?

When to check with the council

Before moving a mobile home onto land for anything more than storage, contact the local planning authority. A section 5 declaration under the Planning and Development Act 2000 gives a formal answer on whether what you propose is exempted development.
