Are tenants responsible for their guests violating terms in the lease? For example if a lease says "no smoking in the building" and an invited guest smokes, could the tenant be held responsible?
What should a contract contain to show that any guests are the responsibility of the tenants? I've seen "tenants are responsible for their guests actions" but I'm not sure if this is enough as couldn't a tenant argue "I agreed to follow the terms in the lease, but my guest never did, therefore no violation has occurred." Could a contract say "guests are not allowed to smoke" and still be enforceable considering the guests never signed the contract?
