Can your landlord limit the number of occupants in their property? Probably. The issue of how many tenants can occupy a property is a grey area. Landlords are required by law to follow housing law/regulations, and discrimination must be avoided against potential tenants, especially if they are relatives of the existing tenants. On the flip side, landlords must be careful when they admit new tenants, as too many tenants will result in overcrowding, as well as more tenants, more repairs, and maintenance. So, the number of tenants is really at the discretion of the landlord. The Housing Act 2004, section 258, talks about a building where all the tenants are related. In another situation, if the landlord should rent out the property to 3 or more people from different families, then it becomes House in Multiple Occupation (HMO).
