What Is an HMO (House in Multiple Occupation)?

An HMO (House in Multiple Occupation) is a property rented out by at least three people who are not from one household but share facilities like a bathroom or kitchen. In the UK, HMOs are subject to specific licensing, safety, and management regulations that vary by local council, making compliance the central operational challenge.

HMO licensing in the UK

Larger HMOs require a mandatory licence. Many councils add additional or selective licensing schemes that extend requirements to smaller HMOs, and Article 4 directions can restrict new HMO conversions. Each council sets its own rules, fees, and renewal cycles, so a portfolio operator across several councils faces real per-property variance.

What HMO software needs

Per-room billing, per-council licensing trackers with renewal alerts, Right to Rent checks, deposit protection registration, and management of safety certificates (gas, electrical/EICR, fire). Missing a licensing renewal can mean fines and rent-repayment orders, so tracking is not optional at scale.

HMO vs coliving

HMO is a regulatory classification; coliving is an operating model. Many coliving properties are legally HMOs. The difference is that coliving adds community, amenities, and a branded resident experience on top of the shared-house structure, while a traditional HMO is purely a shared rental.
