Which rules apply in Caterham?
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 Caterham before we price.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- 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.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
