I own a single family dwelling which I started renting out in April. My tenants informed me yesterday that they have problems with roaches and want me to call the exterminator. Since I lived in that house for five years and never encountered such a problem, I am assuming that the roach problem was caused by them. I don't think that I am responsible for their cleanliness. I called the housing authority in Charlotte where I was told that it was definately my responsibility to have the house exterminated. When I inquired about the regulation/law that governs this responsiblity, they were unable to provide me with an answer. I am not asking what I should do, but what the law or statutes say I must. I would be grateful if you could advise me of my rights/responsiblities in that matter.
