Which rules apply in Ayr?
Here is what usually applies to a Ayr job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 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.
- Kitchen, WC and bathroom ratios come from council standards; one WC and one bath or shower per 5 people is a common figure.
