GreenTags

Know what you're walking into. GreenTags turns NYC's open city data into a single score for any building — so buyers, renters, and property managers can see exactly how well a building is being run before signing anything. Every building gets a 0–100 score built from three pillars: Compliance — boiler inspections, elevator reports, facade filings Violations — open DOB safety and HPD housing code violations Energy Efficiency — NYC Energy Star benchmarking One number. No guesswork. For Property Managers Track your entire portfolio on a map. Green pins are healthy. Red pins need attention. Tap any pin to see exactly what's wrong and what it will take to fix it. For Buyers & Renters An apartment is only as good as the building it's in. Check any address before you sign a lease or close a deal. See open violations, inspection history, flood zone, and energy performance — the same data your attorney charges you to find. For Board Members & Realtors Benchmark your building. Share a compliance report with prospective buyers. Export a full PDF summary in one tap. Live City Data GreenTags pulls directly from NYC's Department of Buildings, HPD, LL84 Energy Benchmarking, and FEMA flood maps — updated in real time, no manual entry required.
