- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- 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.
- Where the building regulations apply to a conversion, Part E sound requirements can apply between rooms and floors.
Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.

Questions about commercial and above-shop to HMO in Somerset
Is building control needed?
Yes. Changing commercial space to residential use is a material change of use and needs building regulations approval.
Can offices be converted to an HMO without planning?
Some office-to-home changes have permitted development rights in England, but those rights generally create self-contained flats, and HMO use usually needs its own consent. We work from your planning position and flag anything that needs checking.

Yes, across the whole of Somerset, including Mendip, Bath, Weston-super-Mare.
