Planning Permission in Washington

Planning permission is a system where local authorities can consent to building works by giving permission for the planned work. Garage conversions will often not require planning permission, so long as the work is internal and you do not plan to expand the structure of your property. Garage conversions are often protected by permitted development rights, which cover a variety of home improvement work. However, these rights have been rescinded in certain areas by councils, especially in new builds, therefore it is always worth verifying with your local authority. If you are considering undertaking a garage conversion on a listed building or live in a conservation area, you will require planning permission. In addition, if the walls of your garage are shared walls with a neighbouring property, you will require a Party Wall Agreement. You will still need to adhere to all building regulations corresponding to your garage conversion whether or not you need planning permission. These building regulations cover elements of the conversion like insulation, escape routes, fire proofing and ventilation, so it is usually a good idea to utilise an architect to draw up plans and approve designs in order to ensure compliance with these regulations. You'll likely still need to submit plans detailing the change of use of the garage to your local authority. If planning permission is taken into account from the start of the project, it is far less likely that there will be any trouble further down the line. Nearly all planning permission applications in England are approved.
