Possible 1st HPD Violation in New York City - Do you have experience with this?

[Michael G.]

Folks - I have a question for y'all if you would be kind enough to help out: 

I may possibly be looking at my 1st ever HPD violation warning . The issue is I didn't even know or think that my building was subject to HPD rules since I have no Rent Regulated tenants to my knowledge. 

1.) Can any tenant, no matter how crazed or unjustified, simply file a violation with HPD when they think they have a minor grievance and are not willing to properly communicate with their PM to resolve it (even if they are not living in a rent-regulated apt?)

2.) If it turns out that I indeed end up receiving a violation notice, Does anyone know what the process is to deal with & resolve it?

3.) Can anyone recommend a qualified New York City Rent Regulations specializing attorney I can call to discuss this with? (Please sidebar this info to me)

I usually pride myself on providing tenants with an exceptionally high-degree of service and respect so this development is most disturbing.  Any assistance or information you can offer would be Much appreciated.

Thanks!
