A commercial to HMO conversion turns space that was never a home, such as upper floors over shops or small office buildings, into shared accommodation. In Norwich, a place of roughly 140,000 people in Norfolk, the work is planned around the HMO rules for England and the council’s written HMO standards. With students as well as working sharers renting in Norwich, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Norwich?
Here is what usually applies to a Norwich job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
