It is a requirement of all rented properties which house multiple different people from different families that the building complies with certain guildlines. Where a building is 3 or more storeys with 3 or more different households living in it (ie. three people from different families) it is also required that the property be licensed by the Local Authority.
All of our properties comply with guidleines and where necessary are licensed with the Birmingham City Council. You can find out more about HMO licenses on the Birmingham City councils website http://www.birmingham.gov.uk
