The planning status of a static caravan depends primarily on how it is used and how long it remains in place. The distinction between a temporary incidental use and a permanent change of use is the central planning question for any static caravan on residential land.

Incidental Use: Permitted Development

Under the General Permitted Development Order, a caravan can be stationed within the curtilage of a dwellinghouse incidentally to the enjoyment of that dwelling. This covers the storage of a touring or static caravan as a leisure vehicle, use as occasional overflow accommodation for short stays, or temporary placement during building works. This incidental use is permitted development and does not require planning permission.

The word incidental is important. Incidental means the caravan use is secondary and subordinate to the primary residential use of the property. A caravan parked occasionally for holidays or stored between trips is genuinely incidental. A static caravan installed with running water, permanent connections, and used as regular living accommodation is not incidental to the main dwelling; it is an additional dwelling use that requires planning consent.

Residential Use Requires Planning Permission

Using a static caravan as a permanent or long-term home for any person on a residential property is a material change of use that requires planning permission. This applies whether the caravan is occupied by the homeowner, a family member, or anyone else. The size of the caravan, how comfortable it is, or how modern its facilities does not change the planning position. The residential use of land is what triggers the planning requirement.

Planning authorities are generally not sympathetic to applications for a second dwelling in the garden of an existing house, except in cases where there is a clear need for a family annexe and the proposal is properly designed and controlled. An application for a static caravan as a granny flat, for example, is likely to be refused in most areas because a permanent structure designed for the purpose would be expected rather than a caravan.

Park Home Sites

Established mobile home and park home sites operate under site licences issued under the Mobile Homes Act. Residence on a licensed park home site is entirely lawful and does not require individual planning permission, as the site licence covers the residential use of that land for mobile home occupation. Buying a park home on a licensed site is a distinct route from placing a static caravan in a private garden.

Enforcement

Local authorities can issue enforcement notices requiring the removal of a static caravan being used as a dwelling without planning permission. The caravan is not exempt simply because it is technically moveable. Enforcement action is more likely where the use is permanent, visible, or where complaints have been made.

Summary

A static caravan in a residential garden used incidentally for storage or occasional overflow accommodation is generally permitted development. Permanent residential use of a static caravan requires planning permission as a change of use. Planning permission for a caravan as a second dwelling is difficult to obtain in most residential settings. Park home sites operate separately under site licences and individual residence on them is lawful.
