Which rules apply in Cambridgeshire?

Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
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.

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.
