Tiny Houses and Land in the UK: Do You Need Planning Permission?

Important: this guide is general information to help you ask the right questions. It isn't legal or planning advice, and it can't tell you what's allowed on a particular piece of land. Rules change and every council decides its own cases, so don't rely on this guide to buy a tiny house, buy land or move a home onto it. Before you do, get your council's view in writing, and for a purchase, advice from a planning consultant or solicitor.

"Can I put a tiny house on my land?" is the question we hear most. The honest answer is "usually, but not without asking". This guide covers the rules that apply across the UK, then where England, Wales, Scotland and Northern Ireland differ. Every rule links to the official source.

The short answer

• Living in one full-time on your own land usually needs planning permission. If the tiny house counts as a caravan (most on wheels do), the land also needs a caravan site licence, and the council can only issue that licence once the land has planning permission for that use (England and Scotland, Wales, Northern Ireland).
• In the garden of your own house, it depends on how it's used. Using garden land for something "incidental to the enjoyment" of the house isn't development, so a tiny house used as part of the household often needs no permission. If it becomes a separate, self-contained home, it does. Where that line falls is decided by the council, case by case.
• On foundations, it's a building. A new home built on foundations needs planning permission and building regulations approval (in Scotland, a building warrant).

Is a tiny house a caravan?

In law, a caravan is any structure designed or adapted for people to live in that can be moved from one place to another, whether towed or carried on a trailer. A home made of up to two sections still counts if, once assembled, it's within 20 metres long, 6.8 metres wide and 3.05 metres high inside. Northern Ireland uses the same test.

Most tiny houses on wheels fall inside those limits, so caravan rules apply to them: site licences, and the caravan routes to planning permission. A tiny house fixed to the ground or too big to move is more likely to be treated as a building. If you're not sure which yours is, ask the council before you buy.

The "28-day rule" won't let you live in one

You'll often read that you can use land for anything for 28 days a year. That temporary-use right exists, but it excludes caravans in all four nations, and so do the newer 60-day camping rights (England, Wales, Scotland, Northern Ireland).

What does exist is a short list of caravan exemptions (GB, Northern Ireland). For example: one caravan for a stay of no more than two nights, or up to three caravans for no more than 28 days in 12 months on a holding of five acres or more. These are for short stays, not for living somewhere.

England

• Councils can take enforcement action for 10 years against unauthorised building work or a change of use to a home. Since 25 April 2024 this has been 10 years for everything.
• A Lawful Development Certificate is the council's formal confirmation that an existing or planned use is lawful. If you're buying a tiny house that's already lived in on land without planning permission, ask whether the seller has one.
• Green Belt and the countryside are strictly controlled. New development in the Green Belt is "inappropriate" unless it fits a listed exception, and National Parks and National Landscapes have extra protection.

Wales

• Residential caravan sites are licensed under Wales's own law, the Mobile Homes (Wales) Act 2013. As elsewhere, the licence needs planning permission first.
• One Planet Development is a route only Wales has. It allows low-impact homes, including single homes in the open countryside, if the land meets the residents' basic needs for income, food, energy and waste within no more than five years, the home is zero carbon, and the household lives within a strict ecological footprint (Technical Advice Note 6, section 4.15). It's demanding, but it's the one route designed for living lightly on the land.
• Enforcement is still 4 years for building work and for a change of use to a single home in Wales, and 10 years for other breaches (section 171B).

Scotland

• You need a building warrant to build a new home, and you may need planning permission as well (mygov.scot).
• Letting one to holidaymakers needs a short-term let licence. Shepherd's huts and glamping pods are included, and operating without a licence is a criminal offence with fines of up to £2,500. A unit that used to move but has been fixed in place can still need one.
• Croft land has its own process. To release a house site from a croft ("decrofting"), the Crofting Commission needs a planning application reference first.

Northern Ireland

• The countryside rules on caravans are the strictest in the UK. Under the long-standing countryside policy (PPS 21), planning permission will not be granted for a permanently sited residential caravan or mobile home in the countryside. Temporary permission is possible in exceptional circumstances, normally for three years. Councils that have adopted their own local plan now use their own countryside policies instead, so check with yours.
• In a garden, nidirect says you need to apply to use a building or caravan "as a separate residence for someone else".
• Enforcement is 5 years for every type of breach (section 132).

Council tax and rates

A tiny house that's someone's main home is taxed like any other home. In England, Wales and Scotland, a caravan pitch occupied as someone's main residence counts as a dwelling for council tax (England and Wales, Scotland). In Northern Ireland, domestic rates are paid on every home.

Before you buy a tiny house that comes with land

Ask the seller:

• Does the land have planning permission for someone to live there, and is it permanent, temporary or holiday use only?
• Is there a site licence, if it's a caravan?
• If there's no permission, how long has it been lived in, and is there a certificate of lawfulness?
• Are there conditions, such as holiday use only, or a home tied to a farm or rural business?
• Is it in a Green Belt, National Park, National Landscape (AONB) or on croft land?

Then ask the council. Councils offer pre-application advice, often for a fee, and in Wales they must reply within 21 days. A short letter from the planning office before you buy is worth more than anything a seller tells you, or anything in this guide.
