Which rules apply in Woodford Green?
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 Woodford Green before we price.
- 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.
