Which rules apply in Edmonton?
Loft conversions for extra rooms in Edmonton 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.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
