A Guide to Class MA

Class MA permitted development allows for the conversion of commercial buildings to houses without the need to apply for planning permission. Coming into force in 2021, and updated in 2024 - Class MA replaces Classes G, M, and O, and is intended to help revitalise town centres.

Class MA Permitted Development Rights grant the conversion of spaces like shops, offices, restaurants, cafes, health services, nurseries, gyms, and leisure facilities (Class E properties) into much-needed homes. 

This approach offers the potential to revitalise struggling high streets, transforming empty shops and vacant premises into vibrant and lasting mixed-use residential communities.

With more than 6,000 shop closures across the UK in the past five years, crippling business rates binding the hands of entrepreneurs, and our changing habits altering the way we shop, it's time to ask the crucial question: Can Class MA save the high street?

What is Class MA?

Class MA permitted development allows for the conversion of commercial buildings to houses without the need to apply for planning permission.

Changes to Class MA in 2024

Changes to Class MA permitted development rights came into effect on 5 March 2024 in England and Wales.

The big changes? The previous size limit of 1500 sqm has been scrapped, and the buillding no longer has to been vacant for 3 months.

This change not only creates more opportunities to convert larger units on high streets but also enables the full conversion of buildings that were previously only partially converted

How much can you develop with Class MA?

For any application submitted on or after 5th March 2024, there no limit to the floor space that can be converted and no requirement for the building to be vacant for 3 months.

Previously, Class MA opportunities had to be less than 1500 sqm and be vacant for at least 3 months.

This includes the conversion of ground-floor spaces, upper floors, a mix of both, or even entire buildings.

What to consider when considering Class MA opportunities?

When preparing submissions under Class MA, there are a few key things to be aware of:

  • The property has to have been Use Class E for at least two years
  • From March 4 2024 the requirement for buildings to have been vacant for 3 months has been scrapped.
  • The development must be completed within 3 years of prior approval
  • From March 4 2024 the previous floorspace limit of 1,500 sqm has been scrapped
  • Conversion of health centres and nurseries requires an impact assessment first 
  • The usual places like listed buildings, scheduled monuments, sites of special scientific interest, safety hazard zones, land that comes under Article 2(3), and military explosives areas are still out, but you can make changes in conservation areas
  • If a building requires additional windows, an additional planning application may need to be submitted
  • There may be a fee of £100 - £5000 per new home
  • Some local authorities are planning to bring in new Article 4 restrictions preventing parts of their area from being converted

Class MA Prior Approval Requirements

While Class M opportunities skirt the need for certain forms of development to occur with full planning permission, prior approval requirements still apply, which can include assessments related to the impact on transport and highways, contamination risks, flood vulnerability, noise considerations, window proposals, living space standards, and, concerning the change of use of a health centre or nursery - the impact on the local provision of services lost.
