Begin with eligibility
Class MA is a permitted development route for qualifying changes from Class E commercial, business and service uses to Class C3 dwellings. It includes limitations and a prior approval process. It is not an automatic entitlement for every commercial building. See the GPDO, Schedule 2, Part 3.
Avoid an outdated starting assumption
The 2024 amendment removed the previous three-month vacancy requirement and the 1,500 m² Class MA floorspace limit. That did not remove the remaining eligibility checks or make every conversion acceptable.
Our practical recommendation is to record the source and date of every eligibility check. An old online checklist or a previous owner’s opinion is not a reliable basis for acquisition.
Compare the routes against the actual scheme
Start a route comparison with three columns: the existing use and evidence; the changes you want to make; and the questions that still need specialist investigation.
- Use history: identify the actual activities and supporting documents.
- Site restrictions: check the planning history, conditions, designations and any relevant Article 4 direction.
- Scope of works: distinguish the change of use from extensions or external alterations.
- Living conditions: test the proposed layout and identify matters needing reports.
These are suggested appraisal headings, not an exhaustive statement of Class MA requirements. Obtain a property-specific assessment before choosing the submission route.
Agree the scope before detailed work
A full application may be the route to investigate where the intended development cannot proceed under the permitted development right. Ask your adviser to explain why a route is recommended and what separate consents or design work remain.
Attain can review the planning approach alongside your architect. A useful first enquiry includes the address, current use, available plans and intended number of homes.
