I did that (posted the notice on the screen door and took pictures), however don't know if it's legally served. 

@Alvin Sylvain I agree the emotional support animals are B.S. but they are legal and we have to abide by the law.If the animal is an ESA, you are allowed to ask if the person is disabled and what service the animal provides.

I want to pursue the case without legal help but I fear she might use my email to double down on harassment claims and go for appeal.Really down atm so please advise :)

To legalize a curb cut in NYC, your first step is to hire a licensed architect or engineer.

I don't try to evict based on neighbor complaints as those aren't super reliable and the people likely won't show up to court. 

I've heard nothing but complaints from customers AND their franchise agents reegarding the quality of their 800-number service center. 

It couldn't hurt to call a couple attorneys right away to see what they say in terms of cost and suggestions for dealing with this quickly.In terms of mitigating any legal issues with your tenant be sure you are documenting every conversation you have had with the HOA in terms of asking them to make the necessary repairs.

If it is, explain your situation and ask to file a complaint.

My only complaints with their customer service are 1.

Maybe they've been burned by landlords in the past and are being very careful.You can legally reject them based on personality, facial tattoos, body odor, or other factors, but you better make sure you can prove that it wasn't based on any protected class like race, religion, familial status, etc.
