Which rules apply in Greenock?
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 Greenock 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.
- 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.
