Houses in multiple occupation sit at the junction of planning and licensing: small HMOs fall under use class C4, many boroughs have Article 4 directions requiring planning permission for the change, and licensing sets room sizes and amenity standards.
- Use class and Article 4 check for the borough
- Layout design to licensing space standards
- Planning application where required
- Fire and amenity compliance drawings
Do I need planning permission for a small HMO? +
In boroughs with an Article 4 direction covering C4 use, yes. Elsewhere, changes up to 6 occupants may be permitted development. We confirm your borough's position in writing.
What room sizes do HMOs need? +
National minimums start at 6.51 square metres for a single adult bedroom, and many boroughs set higher standards. Layouts are designed to the standard that will actually be inspected.
