What Is a House in Multiple Occupation

A House in Multiple Occupation, more commonly known as an HMO, is a specific type of residential property where multiple unrelated tenants live under one roof, often sharing common facilities like kitchens and bathrooms. HMOs are widely used in cities and towns across the UK to provide affordable accommodation for students, young professionals and low-income renters. However, they are subject to tighter regulation than standard rental properties due to the increased risks and management responsibilities involved.

Understanding what qualifies as an HMO, how they are regulated, and what landlords need to do to remain compliant is essential for anyone considering letting or investing in this type of property.

Definition of a House in Multiple Occupation

Under the Housing Act 2004, a property is classed as an HMO if at least three tenants live there, forming more than one household, and they share toilet, bathroom or kitchen facilities. A ‘household’ is defined as members of the same family or couple living together. So, three unrelated people renting separate rooms and sharing facilities would meet the HMO criteria.

There are different categories of HMO, including small HMOs and large HMOs. A large HMO is defined as a property occupied by five or more people forming more than one household, sharing amenities. Large HMOs are subject to mandatory licensing in England and Wales. Some local authorities also require licences for smaller HMOs under additional licensing schemes.

Who Does It Affect?

The rules on HMOs affect landlords, letting agents, property managers, tenants and investors. Anyone who owns or manages a property let to unrelated tenants who share facilities must understand their legal responsibilities, especially where licensing applies. Failure to comply can result in financial penalties, prosecution and being banned from letting property altogether.

For tenants, living in an HMO can offer affordable rents and flexible arrangements, but it is also important that the property is well managed and safe. Knowing your rights as an HMO tenant ensures you can raise concerns if standards are not being met.

Legal and Regulatory Framework

HMOs are regulated under the Housing Act 2004, with additional provisions introduced through later legislation and local authority policies. The main requirements for landlords include ensuring the property meets fire safety standards, has adequate kitchen and bathroom facilities, and is not overcrowded.

Large HMOs must be licensed by the local council. The licence will typically last five years and requires landlords to pass a ‘fit and proper person’ test, submit safety certificates and agree to abide by management standards. Local authorities may also inspect the property and impose conditions such as maximum occupancy levels, additional fire doors or regular safety checks.

In many areas, councils operate additional or selective licensing schemes. These may include smaller HMOs or even all private rental properties in specific locations. It is essential to check with your local housing authority to determine whether your property needs a licence.

How to Apply for an HMO Licence

To obtain an HMO licence, the landlord must submit an application to the local authority, including detailed information about the property layout, number of occupants, safety measures and landlord contact details. Fees vary depending on the council but typically range between £500 and £1,500.

As part of the application, the landlord will need to provide gas and electrical safety certificates, fire risk assessments, a floor plan and evidence of management arrangements. Some councils may visit the property before granting a licence or shortly afterwards to check compliance.

Once granted, the licence sets out conditions that must be met, including limits on the number of tenants, frequency of safety checks and expectations for property upkeep. Councils can revoke or refuse licences if landlords breach conditions or are found to be unsuitable.

Ongoing Responsibilities and Management Standards

Managing an HMO involves greater responsibility than a standard rental property. Landlords must ensure that communal areas are kept clean and in good repair, that waste disposal is managed correctly, and that smoke alarms and emergency lighting are tested regularly.

There are specific standards for room sizes in licensed HMOs. For example, a single room must usually be at least 6.51 square metres, and larger rooms require more space depending on occupancy. Landlords must also respond promptly to repairs, maintain records and comply with data protection rules when handling tenant information.

Risks and Common Mistakes

Operating an HMO without the required licence is a criminal offence and can result in a fine of up to £30,000 or prosecution. Even if a property is not classed as a large HMO, failing to check local licensing rules can still leave landlords exposed to penalties.

Common mistakes include underestimating the fire safety requirements, not carrying out sufficient background checks on tenants, or failing to keep up with maintenance in shared areas. Letting agents and property managers acting on behalf of landlords can also be held liable if standards are not met.

Design and Investment Considerations

HMOs can be profitable for landlords due to the higher rental yield compared to single-let properties. However, conversions must be planned carefully to comply with building regulations, planning requirements and HMO licensing rules. In some areas, converting a home to an HMO requires planning permission due to Article 4 Directions that remove permitted development rights.

Landlords must also ensure the layout supports safe and practical living for multiple tenants. Adequate facilities, soundproofing, secure entry systems and clearly defined shared spaces are all important when designing or renovating an HMO.

Case Example

A landlord in Liverpool converted a three-bedroom terraced house into a five-bedroom HMO for young professionals. After applying for planning permission and securing a licence, they installed fire doors, an integrated alarm system and upgraded the kitchen and bathrooms. The property now generates a significantly higher monthly income than a single-let and remains fully compliant with local HMO regulations following annual council inspections.

Conclusion

A House in Multiple Occupation offers an opportunity to meet growing demand for shared housing, particularly in urban areas and university towns. However, HMOs require careful management, licensing and compliance with strict safety and quality standards. Landlords who understand their legal duties, invest in appropriate design and maintain strong tenant relations can benefit from stable income while providing safe and regulated homes for those who need them.
