When you count the number of storeys in a building you need to include: �
- Basement and attics if they are occupied or have been converted for occupation or are in use by residents �
- Any storeys which are occupied by you and your family if you are a resident landlord �
- All storeys in residential occupation, even if they are self-contained �
- Any business premises or storage space on the ground floor or any upper floor.
You don’t need to count basements used for business or storage unless the basement is the only, or principal, entrance to the HMO from the street.
