Tenants are not using the stove responsibly.

[Peter Goeller]

Hello BP forum 6 months ago I bought a 3 family house and I moved into the basement and I am renting the other 2 units out, it has been amazing, I have fixed a few small problems here and there, but my biggest problem is starting to arise... last night I got woken up by the fire alarm going off in the  middle of the night for the 3rd time. Its the tenant on the third floor. there are 2 roommates living up there and one of them uses the stove and completely forgets about it. he will put a pot of pasta on the stove and then fall asleep setting the fire alarm off when all of the water boils out burning the pasta. obviously I should have a conversation with him bringing up the safety concerns but does anyone have any other advice as to what/how to address this problem
