If you end up in court, it's because two parties can't seem to resolve an issue among themselves.

This may force her hand to get a lawyer involved that could help resolve the issue.

Renters insurance is required, so telling them they have to get coverage to include the pitbull may just make the situation resolve itself, as you mentioned im sure it would be very difficult and id imagine pretty expensive to find coverage for a pitbull.

A petition with the SFRB and a mediation meeting with the ALJ that reviews the validity of the rental increase would resolve this with the only out of pocket cost being your time wasted.The real potential cost is what was discussed earlier around the eviction moratorium, court closures and anticipated backlog of filings and cases.

Draft a letter giving them a set amount of time to resolve the issue, then sit back and let them spend money resolving the issue.

@Dillon Lopez I don't know your personal status, but if I was young and single with no kids I would resolve myself to grind the next 5 years.

I will let everyone know how this situation resolves. 

I have tactfully resolved other minor issues but not this one thanks to the pandemic the tenants house wives have nothing worthwhile to do with their time and I find my wife always trying to patiently explain to them why a get together is not possible.

I agree 100% in what you are saying and it can create a problem You need to work with their placement officer or the responsible person (family, etc) and get it resolved.

As an STR owner/operator, I can't necessarily help it when stuff happens, but I CAN help how I respond to it, and I view it as my responsibility to resolve any issues as quickly as possible for my guests.
