NYC Property Data Platform

Proparta aggregates building data from multiple different public databases across NYC, including HPD, DOB, DOF, BIS, OpenData, and much more.

• Overview: Core building information, like registration status, owner information, geolocation, plot, legal status, and more.
• Violations: HPD violations, DOB violations, OATH/ECB violations, and others.
• Penalties: Total number of penalties, open balances, and historical activity.
• Complaints: HPD complaints and DOB complaints, including open and closed counts and historical activity.
• Other: Reports, filings, permits, local law compliance, and more.

Proparta is built to consolidate the NYC building datasets that operators and buyers use most often, so you can review them from one reliable dashboard instead of switching tabs all day.

• HPD for registration, complaints, violations, and work-order activity.
• DOB / BIS for complaints, violations, job filings, and enforcement history.
• DOB Now for active violations and related penalty amounts.
• DOF for tax-lot and assessment context.
• NYC OpenData and related city feeds to help connect the broader building record.
• Other datasets that are relevant to building operations, compliance, and more.

We show live data, so you can work from one up-to-date dashboard instead of checking each agency site by hand.

Absolutely. Instead of jumping between different NYC portals, you can review a building through a single building dashboard that does not crash (cough-cough BIS).

Proparta is always live, fast, and cuts out the tab switching between multiple broken government tabs. You can view all relevant information for a building in one place, getting a clean picture of what matters.

• One search flow: Review multiple agency datasets from one place.
• Better context: See compliance, registration, filings, penalties, and other signals side by side.
• Less interruption: Spend more time making decisions and less time reconciling government records manually.
