I'm looking at renting commercial space, where there are common area washrooms. There are no other washrooms. The Landlord wants me to pay for additional square footage to use the bathrooms and hallway. It adds 350 square feet to my square footage, therefore he wants base rent plus cams and taxes for this common area washroom, added to my overall rent bill. My assumption is that the washroom and hallway is there for both units already and isn't that what CAM's are for? I don't think I should be paying 20 bucks a square foot, or an extra $500.00 plus per month. Am I wrong?
