Which rules apply in Irvine?
The rules below are the Scotland-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Irvine before we price.
- 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.
