No — not as your full-time residence.
A caravan, lodge, log cabin, tiny home or mobile home becomes a “dwelling” if you live in it. That triggers planning rules.
Even hidden or “temporary” setups can still receive:
- enforcement notices
- removal orders
- fines
- legal action
This is the part most don’t want to hear – but it’s the truth.
When You Can Legally Live in a Mobile Home (UK)
These are the only scenarios where you can genuinely live in a mobile home without full planning for a new dwelling.
1. Placing a Mobile Home in the Garden of an Existing House (Curtilage)
This is the most realistic and the most common legal route.
You can place a mobile home in your garden without separate planning permission if:
- The main house remains the primary dwelling
- The mobile home is used by the same household, OR
- It’s for a dependent relative
- It meets the legal size definition of a caravan
This is perfect for:
- downsizing into your garden
- multigenerational living
- granny annexes
- family members needing independence
Read our blog Understanding the Caravan Act for further information on this topic.
2. Incidental Use (NOT a Separate Home)
No planning permission is needed if the mobile home is used as:
- an office
- hobby room
- studio
- gym
- occasional guest space
It must not function as a standalone residence.

3. Temporary Accommodation During a Self-Build or Renovation
Councils often allow this within reasonable conditions:
- You must have planning permission for the main build
- The mobile home is temporary
- You may be required to remove it once the project ends or gain separate planning permission
This is common and often approved informally.
4. Agricultural or Equestrian Worker Accommodation
This can work – but only with genuine need.
You may be allowed to place a mobile home on agricultural or equestrian land if:
- the business requires 24/7 presence
- you can prove functional need
- the business is financially viable
This is called a Rural Workers Dwelling Case and councils take it seriously.
5. The 28-Day Rule (Holiday Use Only)
You can place a mobile home on land for up to 28 days per year without planning.
However:
You cannot live in it full-time under this rule.
What Definitely Does Not Work (Common Myths)
❌ “I own the land so I can live in a caravan.”
False – residential use requires planning.
❌ “Mobile homes don’t count as buildings.”
If lived in: they do.
❌ “If it’s on wheels, it’s legal.”
No – use matters more than wheels.
❌ “If I call it a ‘temporary structure’, I’m covered.”
Incorrect – councils look at actual use, not the label.
