Tenant suit against Landlord or HOA for HOA issues?

[Alan Bosca]

Hi - I have a tenant who seems poised to sue based on “unfair” HOA fines and damages to our building that he agreed to pay for during a move. The fines are from properly noticed noise complaints. My question is whether he would sue the HOA or me and I’ve have to join the HOA in the suit or mediation if he follows up on his claim that the damage bill was too high or the noise level was not bad. Thanks for input!
