I landlord has several apartment buildings and rental unit. He runs a business to rent out these apartments. It is on every rental agreement and list him as the owner. How can i look up information on that business he owns? Also do you have to have some kind of license to rent out apartments and rental units?Information On A Business %26amp; do you have to have a license to own apartments and rental units?You don't need a license exactly, but you need a business registration, which is slightly different in my state. You also need a zoning permit from your local government. You can get information on his businesses from your city (or county if you don't live in a city) and from your state. It might be easiest to start at the city level and contact your local Planning and Zoning department. In my area, this information is not yet available on-line. You can submit a Public Records or Freedom of Information Act request and the local/state government must respond. In my state, they have to respond in 3 days (!) and furnish the information in 2 weeks unless its "broad and burdensome." If it's a huge request--which yours isn't--they can get extra time.
