How Many Tenants Can Legally Share a Home in Northern Ireland?
Living with housemates is common for many renters in Northern Ireland, but there are regulations on how many people can share one property. Understanding these rules is crucial for both comfort and safety, as well as staying within the law. This guide explains shared housing limits, what makes a property a House in Multiple Occupation (HMO), and how official standards affect your tenancy.
Sharing a Property: Key Rules in Northern Ireland
The number of people allowed to live in a property depends on several factors:
- Size and suitability of the property (e.g., number of bedrooms, amenities)
- If the property qualifies as a House in Multiple Occupation (HMO)
- Local council licensing, fire safety, and overcrowding laws
What Is an HMO (House in Multiple Occupation)?
A property is legally an HMO in Northern Ireland if it is:
- Occupied by three or more people from two or more households
- At least some residents share a kitchen, bathroom, or toilet
- It is the main or only residence for those tenants
HMOs must be registered and licensed by the local council. This ensures the property meets safety and space standards. For more, visit the official nidirect HMO hub.
Legal Limits: How Many People is Too Many?
The maximum number of people allowed depends on the property's size and the HMO licence. There are no set national limits, but:
- Each HMO’s licence states a maximum occupancy number based on room sizes and facilities
- The Houses in Multiple Occupation Act (Northern Ireland) 2016 requires landlords to follow these occupancy limits
- Overcrowding rules also apply to all rented homes under the Housing Act 1985 (Section 325) (as adopted in NI)
You can check or challenge occupancy numbers by contacting your local council or using the government’s official council directory.
What Counts as ‘Overcrowding’?
Official overcrowding rules look at two main standards:
- The number of people compared to the number and size of rooms
- The ages, sexes, and relationships of people sharing
Generally, if two people of the opposite sex (unless they are a couple or under 10 years old) have to share a sleeping room, or there is less than 50 square feet per person of available space, the property could be classed as overcrowded. Councils have powers to investigate and require changes if a home is overcrowded.
Official Forms and How to Use Them
- HMO Licence Application – Used by landlords to register the property as an HMO with the council. Tenants can request to see this licence to confirm legal limits for their home.
Find the official form via HMO application forms on nidirect. For example, if you discover more people living in the house than the licence allows, you should alert your council’s HMO unit. - HMO Complaint Form – If you think your landlord is breaching occupancy guidelines or HMO rules, use the HMO Complaint Form (Belfast City Council) to report concerns. Follow your council’s process if outside Belfast.
What Should Tenants Do if They Suspect Overcrowding?
If you think your property is overcrowded or doesn’t follow HMO rules, you can:
- Ask your landlord to provide the current HMO licence
- Contact your local council’s HMO team for an inspection
- File a complaint using the official HMO Complaint Form

FAQ: Shared Housing and HMO Limits in Northern Ireland
- What is the maximum number of tenants allowed in an HMO?
The specific number is set in the HMO licence, based on room sizes and amenities. Your landlord must not exceed this limit – always check the licence if unsure. - Is it illegal to have extra people living in a shared house?
If more people live at the property than the licence allows, or if it causes overcrowding as defined by law, your landlord (and possibly tenants) could face penalties. Report it to the local council if concerned. - Can families share a non-HMO property?
Yes, but the total number of people must still comply with space and overcrowding rules. If multiple unrelated adults share, the home may require an HMO licence. - How can I find out if my rental needs an HMO licence?
Ask your landlord for the licence or check with your local council. If three or more tenants from different households share, an HMO licence is typically needed. - What should I do if my property is unsafe or overcrowded?
Raise your concerns with your landlord first. If not resolved, contact your local council’s HMO team or the Rent Assessment Panel and Private Tenancies Tribunal for help.
