Changing from a commercial use (use class E) to residential(use class C3) falls under permitted development rights, meaning an application for planning permission is not required.
To use the permitted development right you must meet the rules and regulations set out in legislation, this includes submitting an application for prior approval to the local planning authority. The full list of conditions is available on the government website, or our online application form will tell you whether you are eligible.
If you are not eligible for the permitted development right, you will have to submit an application for full planning permission.
Categorising land and buildings according to their type and purpose is known as Use Classes.
A 'Change of use' can be within the same Use Class or from one Use Class to another.
You will need planning permission for certain changes to the use of a property such as changing from a residential use to a business use. However, it is possible to change use between some classes without having to make an application for planning permission.
Depending on the specifics of any proposed change of use, including any building work associated with the proposal, an application for planning permission or prior approval may be required.
Adding an internal wall will not require planning permission or building control approval in most cases. If the building is listed, then you may require listed building consent to make a major alteration to the house.
Any work completed should adhere to building regulations, ensuring fire routes, electrics and ventilation are considered.
An improvement notice is a notice served by a local authority requiring a property owner to carry out specified works to bring a building into compliance with the legal standards. These are most commonly served to landlords to make a building safe.
The notice will specify what works should be completed and when it should begin and be completed by.
Failure to comply with an improvement notice is a criminal offence.
If you want formal confirmation that the existing use of a building is lawful for planning purposes, or that your proposed development does not require planning permission, you can apply for a Lawful Development Certificate(LDC). An LDC can be useful in situations where you need assurance that a particular use, operation, or development is lawful under planning legislation.
