An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Exeter is 36 miles north-east of Plymouth. We price extensions for extra rooms there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. Exeter has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Exeter?
Here is what usually applies to a Exeter job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- 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.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
