The lease will state what responsibilities, if any, the owner will assume concerning repairs and maintenance.
Most leases containing repair clauses require that the following steps be taken to get repairs made.
Be sure to keep a copy for your files. If the manager or property owner refuses to sign the request for repairs, send the notice by certified mail, return receipt requested. If you send the notice by certified mail, you are only required to send one notice. Wait a reasonable time. Reasonable time depends on the nature of the repair.
