A while back, a fellow developer asked me about my experience with MIH units inside a condo building. Funny timing. The day before, I'd toured a condo in Windsor Terrace, and the salesperson mentioned that this condo had MIH rentals. So I sent over the offering plan.
Every New York condo sponsor must file an offering plan (or "condo book") with the Attorney General. The filings contain valuable information about how prior projects were done. The filings are public information, but it requires you to know what to look for and go plan-by-plan. This gap grew into the Condo Book Project, a searchable database of every NYC condo offering plan.
It turns out searching the filings does more than surface facts. Across thousands of buildings, it shows how the industry connects: which developers keep hiring the same architects, which law firms work with which sponsors, which managers are hired for which buildings. From a single condo book, we are building the structured record of the entire NYC real estate ecosystem.
