Which rules apply in Dumbarton?
Loft conversions for extra rooms in Dumbarton must satisfy national law for Scotland, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Scotland has no C4 use class: up to 5 residents can fall within Class 9 (houses), and HMO planning policy is set by each council, some of which require permission at lower numbers.
- A building warrant may be needed for a change of use or for installing a fire alarm system; check with the council’s building standards service.
- The tolerable standard requires interlinked smoke alarms in the main living room and circulation spaces and a heat alarm in the kitchen; licensed HMOs must meet the council’s higher standard.
- Room sizes are set by each council; East Lothian, for example, uses 6.5 m² for a single room with a shared lounge and kitchen, and 10 m² without.
