Donny Zanger founded General Contractor NYC, a licensed contractor referral network serving all five New York City boroughs. He oversees the vetting process that every contractor in the network goes through before any homeowner referral: NYC Home Improvement Contractor license confirmed current, general liability and workers' comp insurance verified, and track record with co-op board alteration agreements, pre-war buildings, and NYC Department of Buildings permit processes reviewed. The network has matched hundreds of Manhattan, Brooklyn, Queens, Bronx, and Staten Island homeowners and investors with licensed contractors across kitchen renovations, bathroom remodels, gut renovations, and full apartment buildouts. General Contractor NYC operates on a straightforward premise: the vetting should happen before the first call, not after a bad hire. Donny built the network around that process.
