Important: Additional Restrictions May Apply in Guildford

Guildford has 40 conservation areas. These include Abbotswood, Abinger Hammer, Albury, Basingstoke Canal North, Basingstoke Canal South, Bisley Camp. If your property is in a conservation area, some or all permitted development rights may be restricted. For example, you may need planning permission for changes that would normally be permitted, including alterations to the roof, cladding, or extensions visible from a public highway.

Guildford has Article 4 directions in force. Article 4 directions remove specific permitted development rights in defined areas. If your property is covered by an Article 4 direction, you may need planning permission for work that would normally be permitted. Contact Guildford planning department to check whether an Article 4 direction applies to your property.

Check with Guildford planning department before starting work to confirm whether your property is affected by any special designations.

Permitted Development Rules for a Carport

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

  • 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?

Building regulations approval is not usually required

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. Even if your project is permitted development, you may still need building regulations approval. Contact Guildford building control or use an approved inspector.

Visit Guildford Planning

If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Guildford. This provides proof that your project does not need planning permission, which can be helpful when selling your property.

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.
