What you must do
What counts as an HMO
A House in Multiple Occupation (HMO) in Northern Ireland is any living accommodation occupied by three or more people who are not all members of the same household. A household is typically a family group or a couple; unrelated sharers living together generally do not form a single household.
It is possible to tip a property into HMO status unintentionally — for example, a landlord who lets to a couple and then permits a third unrelated person to move in may create an unlicensed HMO. If you are in any doubt about whether your property meets the definition, check with the NI HMO Unit before letting.
How the NI scheme is administered
The NI HMO licensing scheme operates differently from most other landlord obligations in Northern Ireland. While obligations such as EICR and alarms are enforced council by council, HMO licensing is administered centrally by the NI HMO Unit, which is based at Belfast City Council and acts on behalf of all 11 councils across Northern Ireland.
All licence applications are processed through the NI HMO Unit, and all enforcement action is taken through it. However, the formal decision to grant a licence rests with the council in whose district the HMO is located — so a licence for a property in Derry City and Strabane District is technically granted by that council, even though the NI HMO Unit handles the process.
Getting a licence
The licence application must be made by the owner of the property (not a managing agent on their own). The process includes:
- A fit-and-proper-person assessment of the owner and any proposed managing agent.
- An inspection of the property to assess its suitability for the specified maximum number of occupants — including the physical condition, room sizes, facilities, fire precautions, and means of escape.
- Publication of notice of the application in a local newspaper within 7 days of submitting the application.
- Once a licence is granted, the owner must give each tenant a copy of the licence and a required information pack.
A licence lasts up to 5 years. The NI HMO Unit will notify you when renewal is due.
The planning and building control trap
Before a new HMO licence will be processed, the property must have planning permission for HMO use and, where applicable, building control approval.
HMO use is classified as "sui generis" in planning terms — a category of its own, distinct from ordinary residential use. This means a property that is already used as a family home does not automatically have permission to operate as an HMO. Planning permission must be obtained from the relevant council before the property is used as an HMO.
This is a common pitfall for first-time HMO landlords who assume that any house can simply be let to multiple sharers. Failing to obtain planning permission before letting as an HMO can put both the licence application and the tenancy arrangements at risk.
Overprovision
A council may refuse a new licence if it determines there is already an overprovision of HMOs in the locality. This is a ground for refusal specific to the HMO Act and means that even a suitable property with a fit-and-proper owner is not guaranteed a licence if the area is considered to have enough HMOs already.
EPC requirement — the one NI minimum rating
As part of meeting licensing standards, an HMO in Northern Ireland must have an EPC with a minimum E rating. This is the one circumstance in Northern Ireland where a minimum EPC rating is required — in contrast to the general NI position, which sets no minimum rating for standard private lets.
Landlords acquiring an older property for HMO use should check its EPC rating before proceeding; a property rated F or G will need improvement works before it can be licensed.
Ongoing licence conditions
Once licensed, an HMO must continue to meet a range of conditions throughout the licence period. These include — at a high level:
- Electrical safety: a valid EICR and electrical installation kept in safe condition.
- CO alarms: carbon monoxide alarms installed where required under the alarms regulations.
- Valid safety and maintenance certificates kept up to date.
- Escape routes and means of escape kept clear at all times.
- The occupancy limit stated in the licence must not be exceeded.
- A complaints register maintained for tenants.
Licence conditions are set out in the licence itself and in the Houses in Multiple Occupation Act (Northern Ireland) 2016. Review your licence document carefully.
HMO landlords must also hold a valid registration with the Landlord Registration Scheme — registration is a separate requirement applying to all private landlords in Northern Ireland, regardless of HMO status.
Penalties and enforcement
Managing or letting a licensable HMO without a valid licence is a criminal offence under the 2016 Act. The NI HMO Unit may issue a fixed penalty notice of £5,000. On summary conviction the maximum penalty is £20,000.
Beyond prosecution, councils have powers to vary or revoke licences and to take enforcement action through the NI HMO Unit.
