In Lisburn, a town of around 80,000 people in County Antrim, the work is planned around the HMO rules for Northern Ireland and the NI HMO standards and licence conditions.

Which rules apply in Lisburn?
Here is what usually applies to a Lisburn job of this kind. It is general information rather than legal advice, and the NI HMO standards and licence conditions have the final detail.
- 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.
- All new HMOs need planning permission; councils such as Belfast apply HMO policy areas and limits on concentration.
- New HMOs need building control approval as well as planning permission.
