Do You Need Planning Permission for a Car Port? UK 2026 Guide

Do you need planning permission for a car port?

Short answer: A car port is usually Permitted Development in England and does not need planning permission, provided it meets the Class E test under the Town and Country Planning (General Permitted Development) (England) Order 2015 (the GPDO). However, several specific scenarios push a car port outside Permitted Development, requiring a planning application.

Whether planning permission is required depends on four factors:

  1. The location of the car port (front, side, rear of the dwelling).
  2. The size of the car port (height, footprint, area relative to the curtilage).
  3. The relationship to the principal elevation of the original house.
  4. Local restrictions (Conservation Area, Area of Outstanding Natural Beauty / National Landscape, Article 4 Direction, listed building).

For the broader context, see our Permitted Development Rights in 2026 guide and our householder planning permission guide.

The Class E test — when a car port is Permitted Development

A car port is generally Permitted Development under Class E, Schedule 2 of the GPDO 2015, which covers “buildings, enclosures, pools and other structures required for a purpose incidental to the enjoyment of the dwelling house.” This Class also covers garden sheds, summerhouses, and similar outbuildings.

Class E applies to a car port provided all of the following limits are satisfied:

  • The car port is within the curtilage of the dwelling house.
  • The car port, together with any other buildings and enclosures within the curtilage (excluding the original dwelling), does not cover more than 50% of the curtilage of the original dwelling.
  • The car port is not forward of the principal elevation of the original dwelling.
  • The car port is not more than 4 metres in height if it has a ridged roof, or not more than 3 metres in height if it has any other roof.
  • The car port is not more than 2.5 metres in height if any part is within 2 metres of a boundary of the curtilage.
  • The car port is for a purpose incidental to the enjoyment of the dwelling house (e.g. a car port for private car parking, not a commercial car park).
  • The car port is not used in connection with a commercial business (e.g. a vehicle repair business).

Where all of these limits are satisfied, the car port is Permitted Development and no planning application is required.

For the broader Class E limits, see our Building Regulations for outbuildings over 30 m² guide.

Front-of-house restrictions

A car port forward of the principal elevation is not Permitted Development under Class E. This means:

  • A car port in the front garden (between the house and the road) is generally not Permitted Development and requires planning permission.
  • A car port to the side of the house may be Permitted Development if it is behind the principal elevation (i.e. set back from the front wall of the house).
  • A car port to the rear of the house is generally Permitted Development provided the height limits are satisfied.

The “principal elevation” is the elevation of the original dwelling that faces the road. Where the road is at the front of the house, the principal elevation is the front. Where the road is at the side or rear (a common arrangement on corner plots), the principal elevation is the road-facing side.

For most semi-detached and terraced houses, the front garden is forward of the principal elevation, so a front-of-house car port is rarely Permitted Development. Many homeowners install a car port on a driveway to the side of the house, which is often Permitted Development because the car port is set back from the principal elevation.

Where a front-of-house car port is proposed, planning permission is required.

Height limits for a car port

The GPDO 2015 height limits for a Class E structure are:

  • Ridged (pitched) roof: maximum 4 metres total height.
  • Any other roof (flat, mono-pitched, hipped, pyramidal): maximum 3 metres total height.
  • Within 2 metres of a boundary: maximum 2.5 metres total height (regardless of roof type).

The height is measured from the ground level at the boundary to the highest point of the structure. For a car port with a pitched roof, the ridge (top) must be no more than 4 metres; for any other shape, the highest point must be no more than 3 metres. Where any part of the car port is within 2 metres of a boundary, the 2.5-metre limit applies to that part.

A car port that exceeds any of these height limits requires planning permission. A two-storey car port is rarely Permitted Development.

Curtilage and the 50% rule

A car port, together with any other Class E structures and any extensions to the original dwelling, must not cover more than 50% of the curtilage of the original dwelling. The “curtilage” is the enclosed area of land immediately surrounding the dwelling, typically including the front, rear, and side gardens.

The 50% test is the most common reason a car port requires planning permission in suburban areas where the garden is small. For example, on a terraced house with a 50 m² rear garden, the cumulative area of all extensions, sheds, and the car port must not exceed 25 m².

Where a car port would push the cumulative area over 50%, planning permission is required.

For a worked example of how the 50% rule applies to a rear garden, see our Building Regulations for outbuildings over 30 m² guide.

Conservation Areas and Permitted Development rights

In a Conservation Area, Permitted Development rights are restricted in two important ways for car ports:

  • Class E prior approval. Under a 2024 update to the GPDO, Class E now requires prior approval for any new building, including a car port, where the LPA must consider the impact on the Conservation Area.
  • Article 4 Directions. Many Conservation Areas have Article 4 Directions in force that withdraw Class E Permitted Development rights entirely. Where an Article 4 Direction is in force, planning permission is required for any car port, regardless of size or location.

For more on Conservation Areas and Article 4 Directions, see our Permitted Development Rights in 2026 guide.

National Landscapes (formerly AONBs) and Permitted Development rights

In an Area of Outstanding Natural Beauty (AONB) — renamed National Landscape in England by the Levelling Up and Regeneration Act 2023 — Permitted Development rights are still in force, but the LPA is required to give greater weight to the conservation of landscape beauty. This can effectively limit the size and design of any car port in a National Landscape.

In a National Park (e.g. the Lake District, Peak District, Snowdonia / Eryri, Dartmoor, Exmoor, the Yorkshire Dales, the North York Moors), planning permission is always required for Class E structures because the National Park Authority is the LPA and applies its own planning policies.

For more on the National Landscape and National Park regimes, see our Permitted Development Rights in 2026 guide.

Listed Buildings and Permitted Development rights

For a listed building, Permitted Development rights do not apply. Planning permission and Listed Building Consent are both required for any car port, even a small one. The Listed Building Consent application is decided separately from the planning application and is concerned with the impact on the special interest of the building.

For more on listed building consent, see our Permitted Development Rights in 2026 guide.

Building Regulations for a car port

A car port is exempt from most Parts of the Building Regulations because it is open on at least one side. However:

  • Part A (Structure) applies if the car port is attached to the dwelling or to another building.
  • Part B (Fire safety) applies if the car port is within 1 metre of a boundary, in which case it must be constructed of non-combustible materials.
  • Part N (Condensation) may apply if the car port is enclosed on three sides with a roof.
  • The electrical work for any lighting or power in the car port is subject to Part P (Electrical safety).

For the broader Building Regulations context, see our Building Regulations UK guide and our Building Regulations for outbuildings over 30 m² guide.

What if planning permission IS required?

Where a car port is outside Permitted Development, planning permission is required. The process is:

  1. Pre-application advice (optional). Most LPAs offer a paid pre-application advice service.
  2. Application submission. Submit the planning application via the Planning Portal, with the required drawings, the application form, and the application fee.
  3. Validation. The LPA validates the application.
  4. Public consultation. The LPA advertises the application by site notice and neighbour letter. The public has 21 days to comment.
  5. Determination. The planning officer determines the application. The statutory determination period is 8 weeks for householder applications.
  6. Decision. The LPA issues a decision notice.
  7. Appeal. If refused, an appeal can be made to the Planning Inspectorate in Bristol.

For the broader planning-permission process, see our householder planning permission guide and our UK Planning Appeals guide.

How to check if your car port is Permitted Development

There are several ways to check whether your car port is Permitted Development:

  • DIY PD check. Walk through the Class E test in the GPDO 2015 and the Schedule 2 limits.
  • Planning Portal PD checker. The Planning Portal hosts an interactive Permitted Development checker that walks through the test step by step.
  • Pre-application enquiry to your LPA. Most LPAs offer a paid pre-application advice service.
  • Independent planning consultant. A chartered planning consultant registered with the RTPI can review the proposal and confirm whether planning permission is required.
  • Certificate of Lawfulness application. Submit a Lawful Development Certificate (LDC) application to your LPA. The LPA will issue a certificate confirming whether the car port is Permitted Development. The fee is typically half the full planning application fee.

The LDC route is the most secure option where the position is unclear, and is often used by homeowners to confirm the position before starting work.

For more on Lawful Development Certificates, see our Permitted Development Rights in 2026 guide.
