In short: A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. Across Midlothian, the work is planned around Scotland’s HMO rules and the standards the local council publishes.

Which rules apply in Midlothian?
- Landlords must also be on the Scottish landlord register, renewed every 3 years.
- 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.
- Kitchen, WC and bathroom ratios come from council standards; one WC and one bath or shower per 5 people is a common figure.
- 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.
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.
