Garage or Car Port

Planning permission is not required for a detached garage or car port provided that:
1. The garage is used for domestic purposes only.
2. The ground area covered by the garage/car port and any other buildings within the boundary of the property, excluding the original house, is not more than half the total area of the property.
3. No part of the garage is in front of the principal or side elevation of the original house that faces onto a road.
4. The maximum height of the garage/car port is 4 metres.
5. The maximum eaves height of the garage/car port is 2.5 metres if it is within 2 metres of the property boundary.
6. No part of the garage is within 3.5 metres of the boundary with a road to the rear of the house.
7. If you live in a house within a World Heritage Site, area of outstanding natural beauty or National Park the maximum total area of ground covered by buildings situated more than 20 metres from any wall of the house does not exceed 10 square metres.
8. If you live in a house within a conservation area, World Heritage Site, area of outstanding natural beauty or National Park the garage is not situated between the principal or side elevation of the house and its boundary.
Measurements are always calculated using external measurements.
Note: A garage which is attached to the house will be treated as an extension for which the rules in Section 1 will apply. Planning permission is not required providing you comply with the rules for building an extension.
If you live in a house which is a listed building, it is likely that you will need Listed Building Consent for any building operations. If the development is within the curtilage of a listed building you may need to submit a planning application for the work unless listed building consent has already been granted. Your local area planning office will be able to advise you.
