Write up a detailed, unemotional (and without anything more than a single brief statement about the prior, similar symptom) incident report, and send it Certified Mail, Return Receipt Requested so you will have proof it was received by the lawful Point of Contact for the Association.

After this incident, NREIG now requires you to sign off every new property added to the portfolio stating it has working smoke detectors. 

If one individual is responsible for most of the trouble, I would probably take pictures to document the incidents as they occur, talk to them directly with a verbal warning, then a written warning, and so on, depending on the tenant laws in your area. 

I had an incident where two grad school roommates moved in together, and one roommate decided to move out early, about 2 months into the lease.  

I've done this many times without incident and work with several repeat buyers who I trust.  

Just because someone took a new job last year as a single incident, that does not mean he is going to be a shorter term tenant.Generally agree with Dawn on her points!

You could have multiple properties with damage from one weather incident.

Examples of good cause include serious or repeated violations of the lease, or criminal activity that threatens the health or safety of other residents.207 However, incidents of domestic violence may not be used as a violation by the victim or threatened victim as good cause for the landlord to terminate the tenancy, occupancy rights or assistance of the victim.208 The landlord must give the tenant a three-day or 30-day or 60-day notice of termination under California law (see pages 67–69), and both the landlord and the tenant must give the public housing agency a copy of the notice.209 What if the landlord simply decides not to renew the lease, or decides to terminate the HAP (housing assistance payment) contract?

He probably heard about the snake incident and the theft of power incident, but didn't realize that his new tenants were the source of those 2 incidents.What I tried to do was give my problem tenants to my competition so that they would be discouraged with their first STR, and less likely to continue the practice. 

If they are sued due a covered incident, the company will pay for defense and/or to settle the claim.
