Or their kids were completely out of control running through the building and up and down the stairs without the parents controlling them, and I was sure they would be too disruptive to the other tenants.  

OP did not mention this person causing disruptions or complaints from neighbors.

Tenants don't like to have their lives disrupted by maintenance people, so they tend to not report problems. 

Read your lease, mine says tenants have the right to have quiet enjoyment of their place, so if a tenant disrupts that quiet enjoyment that is basis for eviction.

The easiest way to disrupt or prevent an easement by perscription is by giving consent.

Hey everyone I'm a big fan of the forums and podcast and this question may be a little out of the ordinary but here it is.

I live in the SF Bay Area and have some very loud, dirty and overall disrespectful neighbors ...

My life would be upended with people coming into my space, my bathroom would be torn up for however long - when I would have rather left things the way they were and not have my home invaded and disrupted by construction and workers, etc.And I think landlords also forget that tenants aren't really in a position to tell you that they actually hate what you're doing.  

Of course we all have terms in the lease that prohibit general disruptive behavior. 

Regarding #1, a neighbor would need to show your tenants disrupted their quiet enjoyment of their own property and that material damages resulted.  

I do hate evictions because they disrupt everyone involved, but in some cases, the problems will continue to intensify.
