- 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.

- 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.
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.
