Tenants behavior is escalating and I found out by a bit of sleuthing  that tenant did not allow the previous LL entry after requesting a list of repairs and was a complete terror.  

is it a civil matter ( small claims) or can the city line like a code violation.I bet tomorrow you will see 1000 landlords in pioneer square demonstrating breaking windows and doing all manner of dectructive behavior

My understanding is that you still need a lease with a tenant, and the roommate agreement can spell out in more detail the day to day behavior and living conditions within the house - diving of chores, noise, etc.

You can expect nonsense like this to continue to increase for two reasons: the increasing felony population in certain cities and the increasing number of leftist politicians that see housing as a right.The main thing to remember is that you can't base a decision on criminal behavior but that doesn't mean you can't reject them for other reasons.

Most of these others don't and you can find more frauds and scammers on BP promoting dishonest, illegal, and unethical behavior.

well without dual agent complexity, this is the behavior of 88.88% of bay area realtor anyway.It's almost like Mafia Cartel in disguise here, mostly bad actors LOLI have been treated worse and give 'em my middle finger

Reward good behavior and taking responsibility. 

-Carefully review the lease agreement you have with the tenant to see if there are any clauses related to behavior, harassment, or violation of terms.

Reduced Liability: By having a pet addendum, you can outline specific guidelines for pet behaviors, including who is responsible for any damage or injuries caused by the pet.

Take this time to learn all you can about contracts, negotiations, financing and human behavior.
