Make it part of your system to do an inspection every 6 months, where you check smoke detector batteries, filter, check for leaks, running toilets, etc.But, no, the appliances are your responsibility, unless you have a lease and state laws that allow you to make the tenant responsible.  

In the future, make sure language in the lease addresses this.You want to avoid having a tenant work on your property for a few reasons: The work may be done poorly and you'll have to redo it; the tenant may become injured doing the work and bring a lawsuit against you; it muddies the waters of your  existing relationship.The most I allow my tenants to do is change out the smoke detector batteries if needed- even that is in the lease.Good luck!

We just checked smoke detectors, changed the batteries, checked carbon monoxide detectors, checked for plumbing leaks, checked for running toilets, leaking a/c unit, and asked if they had anything they needed fixed.  

So maybe some new tech there but I would be surprised.I would even put yeast down the toilet every time I changed the batteries in the smoke detectors. 

Then, schedule an inspection in a month or so saying you need to check the smoke detector batteries and check for plumbing leaks. 

Make sure the smoke detectors meet requirements - some have to be replaced if a certain age, make sure the batteries are new.  

First let me say this- if it is more than replacing light bulbs, batteries and filters I don't let tenants touch anything.

Then a guy popes out of their unit and says to my tenants "Thanks for the battery bro".

I used to be an onsite manager less than 6 months ago in CA so that would be my feedback.the other stuff is not that important, it won't net much gain in rents.your annual maintenance is critical on each unit  - caulking, changing flappers and batteries on smoke detectors, co detectors and changing air filters.

If I in fact remove that tenant's hand upon being 3 days late (with their willingly given permission).... a signed document allowing me to do so would not prevent a charge of battery levied by law enforcement.No Lease Agreement can supersede Federal or State law.
