Always use a utility escalator clause that way you can increase their rent even if they have a lease. --24.34.xxx.x

I've always wondered if you could put a fine in your lease if you find a window open like that. --167.6.xxx.xx

You put another t-stat someplace where it can not be tampered with and do nothing with the one that used to be connected so they will wear the paint off trying to turn it up-n-down making the heat come on, the windows will be closed automatically. --99.160.xx.xxx

Tenants are really a different animal. Perhaps they had their stove on and they got too hot, but normally, tenants can withstand 90 degrees without breaking a sweat. See why the window was open. Trust me.........opening a window to cool things down is no sweat for a tenant when the heat is paid by the landlord. It's a long-haul to figure out how to correct the problem on a multi-unit. --212.117.xxx.xxx

I'd have a window mounted switch of some sort tied to the thermostat. --66.137.xxx.xxx

My tenants that live in my utilities-included apartments like to run around in tank-tops and shorts in the wintertime. I've seen them go to the mailbox in that atire. Come summer..........they will have sweats on and want to know why the A/C isn't working so well. They are really..... touched-by-the-Sprit in my thinking. It's really bad that the landlord has to baby-sit these adults so they don't abuse our utilities. There are a lot of nut-cases out there and they are invading. Help us all, Obama.!!!! --212.117.xxx.xxx

Had to laugh...I have seen tenants run around in tank tops in the winter then open the slider to cool off. Forgot all about the sweatshirts and AC in summer though! --98.118.xxx.xxx

Unfortunately, I don't have an answer to your question. But, have you considered installing electric baseboard heating in the units? This will put each tenants heat on their own dime. --98.227.xxx.xxx

If the boiler is using the old fashion dail type indoor outdoor boiler control then the heat will turn up when the windows are open. First one needs to change the boiler control to a electronic type where the temperature will be more precise. Installing locking non-electric radiator thermostatic valves will decrease the overall hot water temperature where the tenants will not be able to leave windows open without the temperature dropping in the suites. This year dropped the temperature in the apartment building from 22C to 21C along with adding more insulation in the boiler area and basement area. Noticed the tenants were not openning the windows for very long as the temperature dropped in the suites. Slowly changing the adjustable non-electric radiator valves to limiting ones where the heat is more restricted. In the apartment building using a tekmar electronic boiler control for the boilers and indirect hot water tank. In the suites using Danfoss and Honeywell Braukman non-electric thermostatic radiator valves. The high efficiency gas boilers also have temperature limits where as the outside temperature increases then boiler temperature decreases. There is sensor on the outside which connects to each boiler electronic control. The other option is installing wall mounted gas boilers in the suites then separating out the heat for each tenant where the tenant will pay and control the heat. --216.209.xxx.xx

You can tell your longer lease term tenant that his/her rent will be going up next year since they are wasting energy and then just keep after them and take pictures etc. in case you want to get them out. --76.99.xxx.xx
