For issues not involving safety, you should advise the landlord in writing of the specific items needing repair. The letter should state that the landlord has a reasonable amount of time not to exceed thirty days, from the date of receipt to make the repairs. You should consider sending the letter via certified mail so the delivery date is noted. If repairs are still not made, the tenant may place the rent in an escrow account with the General District Court having jurisdiction in that locality.
