The definition of an HMO
A property is an HMO if it is occupied by three or more people forming two or more households who share facilities such as a kitchen or bathroom. This applies to shared houses, bedsits, converted flats and purpose-built student accommodation. A household is a single person or a group of people related by blood, marriage or civil partnership.
The two legal frameworks
HMO landlords face requirements under two separate pieces of legislation. The Regulatory Reform (Fire Safety) Order 2005 applies to communal areas of all HMOs. The Housing Act 2004 imposes additional fire safety requirements through the HHSRS (Housing Health and Safety Rating System) and the HMO licensing regime.
HMO licensing and fire risk assessments
Mandatory HMO licensing applies to properties of five or more tenants in two or more households. All local authorities have power to introduce additional licensing schemes covering smaller HMOs. In both cases, a valid fire risk assessment is a core licensing condition. A licence application without one will not be processed.
"A licence may not be granted unless the authority is satisfied that the proposed licence holder is a fit and proper person and that the house is reasonably suitable for occupation as an HMO."
Housing Act 2004. Fire safety, including a valid fire risk assessment, is a core element of whether an HMO is considered suitable for occupation under licensing requirements.
