- A licence is needed where 3 or more people forming more than two households live as their main home and pay rent; the NI HMO Unit at Belfast City Council licenses for every council.
- Doors on protected routes are typically FD30 or FD30S, self-closing on three hinges; emergency lighting is required in HMOs of 4 or more storeys.
- Licences usually last 5 years, and landlords must also register with the NI landlord registration scheme.
In Northern Ireland, licensing is run centrally by the NI HMO Unit, and all new HMOs need planning permission and building control approval from the local council.
