Permitted Development Rules for a Change of Use
Planning permission is usually required for a change of use. However, some changes are permitted under Part 3 of the GPDO. For example, a dwelling (Use Class C3) can be changed to a small HMO for up to 6 people (Use Class C4) without planning permission under Class L. Other changes between use classes may be permitted or may require prior approval.
Conditions
- 1Most changes of use require a planning application
- 2C3 (dwelling) to C4 (small HMO, up to 6 people): PD under Part 3, Class L
- 3Some commercial-to-residential conversions are PD under prior approval (Class MA, formerly Class O)
- 4Prior approval applications are assessed on specific criteria (flood risk, transport, contamination, etc.)
- 5Article 4 directions can remove C3 to C4 PD rights (common in areas with high HMO concentrations)
Size and Dimension Limits
- Depends on the specific change of use; no general dimensions apply
When Permitted Development Does Not Apply
- Article 4 directions are widely used to restrict C3 to C4 changes in university towns and cities
- Prior approval for commercial-to-residential has minimum space standards and other conditions
- Some changes of use also require Building Regulations approval (especially to residential)
- The Use Classes Order defines what constitutes a material change of use
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply when a building is being converted to a different use, particularly to residential use. Covers fire safety (means of escape, fire detection, fire separation), structural adequacy, sound insulation, thermal performance, ventilation, drainage, and accessibility. The specific requirements depend on the new use.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Maldon building control or use an approved inspector.
How to Apply in Maldon
If you need planning permission for your change of use, you can apply through Maldon's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Maldon. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
High enforcement risk. Unauthorised changes of use are a serious planning breach. The council can serve an enforcement notice requiring the use to revert to the lawful use. For changes to residential use, there is a 4-year enforcement time limit; for other changes of use, it is 10 years. Operating a business from a residential property without permission can also attract enforcement.
