Which rules apply in County Down?

The NIFRS HMO Fire Safety Guide (July 2026) usually expects Grade D1 interlinked detection in smaller shared houses and a Grade A system with more than 6 occupants or over 200 m².
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.
New HMOs need building control approval as well as planning permission.
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.

Questions about HMO fire safety upgrades in County Down

What fire safety does an HMO legally need?

The law asks for the house to be reasonably safe, with suitable fire precautions for its size and layout. The detail usually comes from a fire risk assessment and council guidance, so the right answer for a three-storey seven-bed house is very different from a two-storey three-bed one.

Do all doors need to be fire doors?

Not always. Guidance usually focuses on doors to rooms that open onto the escape route. The assessment sets out which doors need upgrading.

Do you carry out HMO fire safety upgrades across County Down?

Yes, across the whole of County Down, including Bangor (County Down), Banbridge, Holywood.

Who licenses HMOs in County Down?

HMO licensing in County Down, as everywhere in Northern Ireland, is run by the NI HMO Unit at Belfast City Council. Planning and building control are handled by the local council.
