Help needed getting out of lease with awful neighbors!

[David Williams]

I have some family members here in Denver in a bit of a hellhole of a rental situation. They live in the lower level of an up/down 4-plex. The residents above are chronically violating their lease and a true nuisance to live below. They are loud at all hours, smoke indoors, do not pick up dog poop, use marijuana and other drugs in home. My family members have attempted to speak directly with upstairs tenants to resolve issues and are only met with passive aggressiveness and denials. The property managers have been contacted, multiple complaints filed and there is no resolution. Property management company has a history of poorly management.  Situation has gotten to the point its no longer habitable to live below with noise, smoke and upstairs tenants controlling temperatures and keeping lower unit cold in winter months. They have attempted to work out an exit with the property manager, but are only being met with resistance. There is $500 charge to break lease and potential loss of security deposit. They are looking for a way out, is this a time to involve an attorney or are attorney charges likely to exceed breaking the lease.  I have single family units with great tenants and personally have not ran into issues of this nature. Any advice would be greatly appreciated!
