Which rules apply in Na h-Eileanan Siar?
- Every HMO needs a council licence: 3 or more people who are not all from one or two families, sharing basic amenities. Licences last up to 3 years.
- 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.
- Building standards apply to new partitions and conversions, and councils may set expectations through licence conditions.
Scottish councils set their own HMO licence standards and planning policies. Every HMO needs a licence, so check the council’s standards before you design the layout.
