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 Finchley, a town of around 65,000 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 Finchley?
Commercial and above-shop to HMO in Finchley must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
- 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.
