Top / Bottom duplex rental agreement suggestions / advice?

[Michael Ernst]

Anyone have any experience with renting out a top/bottom duplex to 2 different tenants?

I'm looking for some help with the following questions to put into an agreement:

How to deal with excess noise from either tenant written into the agreement.

How to deal with heat/gas/electric since they are not separated out. I was thinking of building this into the agreement in a way where I pay for the utilities in return for upping rent to cover it. This way both tenats are worry free about who uses more electric/gas throughout the month.

Heating cooling is central but only controllable in the upstairs appt. I was thinking to use dampeners on all the downstairs vents and leaving electric heaters and an electric AC to use if needed for basement tenants so they have more control over their environment. The boiler and hot water heater room will only be accessible by myself since it has a door sectioning it off. I was going to add into the agreement that I will provide these heating and AC units for the basement tenants but they need to make sure they call the PM for any issues.

Property has a 2 car garage but I don't want to split it between tenants as this could cause tension. There is plenty of on-street parking in this area though so if the agreement says on-street only with no access to the garage for one of the tenants is that ok?

Anything other advice on this type of rental would be greatly appreciated!

Thanks!
