Well, I feel like kind of a failure now...Good for her.  

Typically, the hoa is responsible for failure of Their pipes, the "common" pipes in between walls and ceilings.  

I would talk with your lawyer of failure of code enforcement at the city level. 

Same thing for a  title loan or failure to pay a car loan. 

I'd love to hear about success stories, failures, pitfalls etc. 

You're setting me up for failure.

App_...If the failure to comply with s.83.51(1) or material provisions of the rental agreement is due to causes beyond the control of the landlord and the landlord has made and continues to make every reasonable effort to correct the failure to comply, the rental agreement may be terminated or altered by the parties, as follows: (a) If the landlord’s failure to comply renders the dwelling unit untenantable and the tenant vacates, the tenant shall not be liable for rent during the period the dwelling unit remains uninhabitable.So Thomas S is wrong.   

The failure can cause water leakage and flooding in homes resulting in severe property damage.

Honestly how do landlords get themselves so stuck.. inherited problems or not.. this sounds like it would have been the first thing I would have done was to get rid of the dogs.Tell tenant you have no choice they either get dogs gone or else, you file for eviction,  non-compliance failure to permit management / services to enter apartment to do emergency repairs. 

You'll minimize your risk of failure and improve your probability of profit/success with a larger reserve.
