I would start off by reading your lease in detail and finding out why the landlord does not want the HVAC system to be used. There might be an easily obtained solution if you talk to the landlord.
However, if you are in a positions where you must install some type of ventilation system check with your city planning and zoning office. They will surely be able to provide information on specific requirements that may be needed. You probably will need to hire a contractor to install the system. Make sure to check out their license and bonding to protect yourself through the process.
