Hi Michael,
This depends on if you have a Full Service Lease, or a Net Lease. You must read the language and it will spell out what you are responsible for ans what the Landlord is responsible for. Usually office buildings are full service but not always. If you need further assistance I would be glad to review it and render my opinion, but I am not an attorney or attempting to render legal advice, only real estate savvy.
