Which rules apply in Kingswood?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Kingswood before we price.
- 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.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
