Which rules apply in South Lanarkshire?
- 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.
- Kitchen, WC and bathroom ratios come from council standards; one WC and one bath or shower per 5 people is a common figure.
- Councils set HMO fire standards through licence conditions, often including emergency lighting in larger HMOs.
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.
