Which rules apply in Barnet?
Small HMO conversions (3–6 sharers) in Barnet 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:
- Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
- Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
- 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.
