So I had an AST with two separate lady tenants on the contract. After they left a neighbour told me that one of them had a young daughter and dog also at the flat and and a frequent man staying at the flat without permission. The tenancy agreement states that only tenants and occasional visitors can stay and no pets without permission.
My understanding is that 3 residents in 2 families turns this into an HMO with much stricter fire regulations. The local authority also has a mandatory and additional HMO registration scheme so I may be in breach of HMO regulations.
Should I be taking action against these tenants for breach of contract and HMO regulations?
