Do I Need an HMO Licence in Scotland? The Three-Person Rule Explained

The Scottish Three-Person Test

Scotland defines a House in Multiple Occupation under Part 5 of the Housing (Scotland) Act 2006. A property is an HMO if three or more people from three or more separate families share it as their only or main residence and share at least one basic facility — a toilet, washing facility, or kitchen.

That threshold is lower than England's. In England, mandatory HMO licensing kicks in at five people forming two or more households. In Scotland, three unrelated flatmates sharing a kitchen trigger the same obligation. There is no "additional" or "selective" licensing tier — one national rule applies to every local authority.

The test is straightforward: count the people, then count the families. Two couples and a single person make three family units and five people — that needs a licence. A couple sharing with one friend makes two family units and three people — it doesn't.

What Counts as a Family

Section 128 of the 2006 Act defines who belongs to the same family. Married couples, civil partners, and cohabiting partners all count as one family unit. Children, stepchildren, foster children, grandchildren, parents, grandparents, siblings, aunts, uncles, nephews, and nieces of either partner fall into the same unit. Half-blood relationships count as whole blood.

A parent renting a flat for three university students who are all siblings would house one family — no licence needed. But a parent renting to their own child plus two unrelated students creates three family units and triggers the requirement.

Students living in a property during term time are treated as having it as their only or main residence under section 125(2), regardless of where they go during holidays.

Resident Landlord Exemptions

A live-in landlord renting rooms in their own home to up to two lodgers is exempt from HMO licensing. The key word is two. Take on a third lodger who is unrelated to you and to the other lodgers, and the three-person threshold applies.

Other statutory exemptions under section 126 cover care homes registered with the Care Inspectorate, armed forces accommodation, religious communities (plus no more than two non-members), and properties under local authority management orders. Using a letting agent does not create an exemption — both owner and agent must appear on the licence.

The Licensing and Registration Distinction

HMO licensing is separate from landlord registration. Every private landlord in Scotland must register on the Scottish Landlord Register under the Antisocial Behaviour etc. (Scotland) Act 2004 — that applies whether you have one tenant or ten. An HMO licence is an additional requirement on top of registration, specifically for shared properties meeting the three-person test.

Having an HMO licence does save you the landlord registration fee (£85 principal + £20 per property) for that specific property — the council passports your fit-and-proper status across both systems.

Planning Permission Is Separate Too

An HMO licence granted by the council's Licensing Department does not mean you have planning permission. Under Scottish planning law, changing a residential property from Class 9 (houses) to Sui Generis HMO use is a material change of use requiring planning consent. Edinburgh, Glasgow, Aberdeen, and Dundee all enforce this. Failing to check can lead to your licence application being referred to a committee hearing after a neighbour or community council objects.

What Happens If You Get It Wrong

Operating an unlicensed HMO in Scotland is a criminal offence under section 154 of the 2006 Act. The maximum fine is £50,000 on summary conviction. The council can also serve a Rent Suspension Order under section 144, making it illegal for you to collect rent while the order is in force. Tenants in an unlicensed HMO may apply for a rent relief order through the First-tier Tribunal.

The financial risk of not licensing far exceeds the cost of the licence itself or the time spent on the application.

Next Steps

If your property has three or more unrelated occupants sharing facilities, you need to apply for an HMO licence from your local council.
