Which rules apply in Dorset?
- Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
- 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.

Yes, with the right consents in place. Older high street buildings often need extra care with windows, fire upgrades and sound insulation.

The homes above must be separated from the commercial unit by fire-resisting construction, and the escape route must not pass through the shop. We design the separation as part of the building control application.

Yes, across the whole of Dorset, including Bournemouth, Poole, Weymouth.
