I am purchasing a new building in upstate New York. How do I convert it into a Condo? It is  vacant.

A bit confused here. No offense but you should know the answer to that question before purchasing - which is why I'm confused!

Can it legally be converted would be my first question, second would be what's the zoning and permitted use? Is it currently a multi-unit? Condos are regulated by NY Department of State and you have to file all sorts of fun stuff with the AG.

Peek at these then I'd suggest consulting a RE attorney or maybe a commercial RE agent who's got experience with conversion.

Thank you for responding. Sorry for the confusion. The building was abandoned for many years. They building certificate of occupancy was changed a couple of times by the county. It was a Multi family, then a commercial and now a single family. I am in the process of building a 8700 square foot modular condo in Newburgh and stumbling along  in Port Jervis. I am new to this process.  This is different from my many years enforcing the law.  I am looking for an attorney that is familiar with the area and experience in the process. Thank you for taking the time.
