You and the neighbors can sue them as a neighborhood nuisance that is hurting your quality of life. I and a bunch of my tenants did it successfully years ago in a Normal Heights rental complex I owned. The Apt. building next door had years upon years of drug dealing, junked cars, trash, noise, crime, police visits, etc.
Under a San Diego program I hope is still in place, we kept logs, photographs, police report logs, & other evidence of the neighborhood disruption (what we economists call negative externalities) as spewed by the nonresponsive and utterly indifferent owner/landlord.
Went to court, won. Every tenant participating got from several hundred $ to several thousand, based on proximity to the problem.
That was soooo satisfying.
The problems abated, somewhat. Had they continued, we could have repeated the process.
