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. For a house in Sutton we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.

Which rules apply in Sutton?
Here is what usually applies to a Sutton job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- 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.
