Which rules apply in South Ayrshire?
- 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.
- Councils set HMO fire standards through licence conditions, often including emergency lighting in larger HMOs.
- 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.
- 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.
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.
