Which rules apply in Muswell Hill?
Loft conversions for extra rooms in Muswell Hill 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:
- 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.
- 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.
