A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. In Antrim, a town of about 20,000 people, the work is planned around the HMO rules for Northern Ireland and the NI HMO standards and licence conditions.

Which rules apply in Antrim?
House to HMO conversion in Antrim must satisfy national law for Northern Ireland, the NI HMO standards and licence conditions and, where walls, drainage or fire separation change, the building rules. In short:
- 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.
- Space and amenity standards come from the HMO (Living Accommodation Standard) Regulations (NI) 2019 and the licence conditions.
- Kitchens, bathrooms and WCs must meet the 2019 living accommodation standard regulations and licence conditions.
- All new HMOs need planning permission; councils such as Belfast apply HMO policy areas and limits on concentration.
