In most cases it's the landlords, but there are items where the landlord and tenant may discuss and designate who wants to do it such as smoke alarm batteries, light bulbs, pest control, refrigerator water dispenser filters etc etc etc...Usually, if the landlord provided the appliance, the landlord is responsible for it's maintenance. 

I am looking for 3-4 duplex modulers and one fourplex. 

One municipality requires both hard wired and battery operated CO and Smoke detectors in every dwelling be it SFH or Multi.This is why it is best to work with people that know the local markets.

That time spent left me no time to recharge my batteries, and more importantly spend time as the "visionary" to review and optimize my portfolio.

My channel manager has 2 AAA batteries. 

The Illinois Rental Property Owners Association is opposed to this unnecessary legislation.Here are the reasons why: The type of battery in a smoke detector does not make the detector work betterPeople remove batteries when the detector goes off while cooking.

They use 9 volt batteries with a battery life of 3 years, so I change the batteries every 1-2 years. 

I get the sealed battery 10 year life detector. 

We were recently mandated to install complete fire sprinkler systems & I have been actively doing it along with the required hardwired/battery backup EXIT signs. 

Yes, the tenant should be responsible for snow removal, landscape maintenance, replacing light bulbs & replacing batteries in smoke detectors per the lease agreement on a single family property.Paint, flooring, plumbing and kitchen appliances are probably the most unpredictable on the list.
