This is general guidance based on standard permitted development rights in England. Rules differ for listed buildings, conservation areas, and properties with Article 4 directions. Always confirm with your local planning authority before starting work.
Do I Need Planning Permission for a Carport?
A covered structure for parking vehicles, open on at least two sides. Carports follow the same PD rules as outbuildings, with the additional requirement that they must remain open-sided.
The General Position
This project is usually allowed under permitted development rights without needing to apply for planning permission, provided certain conditions and limits are met.
Generally permitted under Part 1, Class E as an outbuilding. A carport must be open on at least two sides to distinguish it from a garage. The same height and area limits apply as for other outbuildings.
Conditions and Requirements
- 1Must be open on at least two sides
- 2Must not be forward of the principal elevation fronting a highway
- 3Same height limits as outbuildings (2.5m within 2m of boundary; 4m/3m elsewhere)
- 4Must not cover more than half the curtilage
Size and Dimension Limits
- Height within 2m of boundary: 2.5m maximum
- Height elsewhere: 4m (dual pitch) or 3m (other roofs)
- Total outbuilding area must not exceed 50% of curtilage
When Permitted Development Does Not Apply
- Enclosing a carport on more sides effectively creates a garage, potentially changing its PD status
- Designated area restrictions apply
- Must remain for purposes incidental to the dwelling
What About Building Regulations?
Carports are normally exempt from Building Regulations as open-sided structures under 30 square metres. If enclosed, the same rules as outbuildings apply based on floor area and proximity to boundaries.
Building regulations are separate from planning permission. You may need both, one, or neither depending on your project. Building regulations cover the safety and quality of building work, including structural integrity, fire safety, insulation, ventilation, and drainage.
How to Apply for Planning Permission
Check if you need permission
Review the permitted development rules above. If in doubt, contact your council or apply for a Lawful Development Certificate.
Prepare your application
You will need scaled drawings, a site plan, and a completed application form. An architect or planning consultant can help with this.
Submit to your local council
Applications can be submitted online via the Planning Portal or directly to your council. Select your council below for a direct link.
Wait for a decision
8 weeks for householder planning applications if PP is needed..
Application cost: £258.
What Happens If I Build Without Permission?
Low risk if within PD limits. Enclosing a carport to create a garage without checking PD compliance could attract enforcement. Carports forward of the principal elevation are not permitted development.
