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 Tottenham, a place of roughly 130,000 people in Greater London, the work is planned around the HMO rules for England and the council’s written HMO standards.

Which rules apply in Tottenham?
Here is what usually applies to a Tottenham 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.
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
