Which rules apply in Finchley?
House to HMO conversion in Finchley must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- 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.
