Northern Ireland uses its own HMO licensing route. Treat it as separate from England, Wales and Scotland when checking an HMO purchase or sale.
Shared accommodation can fall under HMO licensing once three or more people live there.
The household test is different from the Scottish three-family threshold.
Licence applications are handled through Belfast City Council's NI HMO Unit.
What changes in Northern Ireland?
Northern Ireland has a specific HMO licensing system. Check the NI HMO Unit guidance before marketing or buying an HMO.
The broad test looks at occupation by three or more people from more than one household who share basic amenities.
Belfast City Council administers HMO applications for Northern Ireland through the NI HMO Unit.
Licensing is not the same as planning consent. Check the local planning position before relying on continued HMO use.
Buyers should review the licence, occupancy limit, conditions, inspection correspondence, tenancy file and any enforcement history.
Sellers should make the HMO licence, safety records, rent schedule and management evidence easy for buyers to verify.
Documents to gather
- Current HMO licence, occupancy limit and conditions.
- NI HMO Unit application, renewal and inspection correspondence.
- Planning history and any change-of-use advice.
- Fire, gas, electrical, management and repair records.
- Room rent schedule, tenancy records and deposit evidence.
- Any notices, restrictions, complaints or enforcement history.
Official Northern Ireland guidance
Use Northern Ireland HMO guidance and the local planning position for the property address because licensing, evidence and planning issues can vary.
