Typically in all landlord tenant situations there is a reasonable time period for maintenance to make the necessary repairs depending upon the scope of the work needed to be done and the complexity of the work.In your matter, you were dealt an unfortunate situation where the maintenance person doing the work on your rental injured himself or herself and as a result there has been a delay in getting the work completed.You need to contact your landlord or the property manager concerning the delay in getting the work completed in a timely fashion and your dissatisfaction. Follow up the telephone call with a written letter suggesting that another maintenance person be brought in to get the job completed.There is nothing illegal for a maintance person to leave tools at your rental during the work in process.Good luck.
