A garage conversion can often be considered permitted development, not requiring an application for planning permission, provided they meet all the necessary criteria and there are no constraints that restrict or remove permitted development rights. If your intention is to convert a garage into a separate house (regardless of who will occupy it), then planning permission may be required no matter what work is involved.
For garage conversions that are likely to fall within permitted development a lawful development certificate is recommended, so that you know your project is compliant and is protected from any retrospective planning issues, enforcements or penalties. Where work is proposed to a listed building, listed building consent may be required. Building regulations may also be required depending on the extent of the works.
It is important to note that permitted development allowances for converting garages applies to houses but not to flats and maisonettes. All flats and maisonettes will require full planning permission. For converted houses or houses created through the permitted development rights a change use maybe required for a garage conversion.
If there are any constraints that limit or remove permitted development rights or even one of these criteria is not met, then you are required to submit an application for planning permission.
If planning permission is required but the works are completed without first securing the proper planning approval you may face retrospective planning issues. If the local planning authority determine that planning permission was required an enforcement and or penalties may be issued. If planning permission cannot be secured retrospectively the converted garage may need to be put back to its original state.
