re this house https://a810-bisweb.nyc.gov/bisweb/PropertyProfileOverviewServlet?boro=4&houseno=12-14&street=30+dr&go2=+GO+&requestid=0 I'm currently considering a house in Queens that was built in 1901 and is being advertised as a 2-family home. However, I've noticed that the property doesn't have a certificate of occupancy, and it's not registered on HPD which has raised some concerns for me. From my research, I've learned that some houses built before 1935 may not require a certificate of occupancy. However, this house has undergone significant renovations and it appears to have originally been a single-family home. I'm wondering if anyone knows whether this house requires the issuance of a retroactive certificate of occupancy. I understand that an inspector or lawyer should catch any issues during the purchase process, but I want to make sure that I'm not missing any major red flags before moving forward. Any insights or advice would be greatly appreciated. [less]
