Renters have devalued the surrounding properties and the owner is not doing anything to correct the situation. What can be done to correct this problem?
The legal answer - highly unlikely, using a nuisance theory. The practical answer - it would be expensive and time consuming to fight it out and may last longer than the current tenants. There might be other avenues to correct the problem, such as Code Enforcement, but since you close to not tell us what the actual problem is it is hard to tell you what can be done.

Generally, the fact that a property is a "rental" and by some accounts may "devalue" surrounding properties is not actionable by itself. However the actions of the tenants may be actionable based on their own. There may be local code violations, violations of covenants or other violations. You've not indicated what the allegations are for the "devaluing" and what demands have been made. You will also have to address the "evidence" proving the tenants caused a devaluation and that the owner had a power to correct. In other words, in theory, yes there may be a cause of action with appropriate proof and evidence but it's far from easy and far from clear. Whether it is cost effective to pursue is another matter.
