Planning Permission in Channel Isles

Planning permission is a system whereby local authorities can agree to building works by giving permission for the proposed work. Garage conversions will usually not require planning permission, as long as the work is internal and you don't plan to expand the structure of your property. Garage conversions tend to be covered under permitted development rights, which protect a variety of home improvement work. However, these rights have been rescinded in a number of areas by councils, particularly in new builds, so it's always worth verifying with your local authority. If you're planning to undertake a garage conversion on a listed building or live in a conservation area, you will need planning permission. In addition, if any of the walls of your garage are shared walls with a neighbouring property, you will need a Party Wall Agreement. You are required to adhere to all building regulations corresponding to your garage conversion whether or not you need planning permission. These building regulations cover parts of the conversion like insulation, escape routes, fire proofing and ventilation, so it is usually a good idea to use an architect to draft technical drawings and to approve designs in order to ensure compliance with these regulations. You will likely still need to submit plans describing the change of use of the garage to your local authority. If planning permission is considered from the start of the project, it is much less likely that there will be any trouble further down the line. The majority of planning permission applications in England are approved.
