New York City · All five boroughs
PROPERTY OS turns fragmented HPD, DOB, ECB and 311 records into an operating system for compliance: detect issues, understand them, prioritize by risk, resolve them with qualified contractors, document the work, and keep monitoring.
Evaluation access is free — no card required.
Immediately hazardous condition recorded by the agency, with its official correct-by date.
Internal progress never changes the agency’s status. Closure is verified against the official record.
Three connected products
Monitor every building’s official records daily. Explainable risk scores, verified-rule exposure estimates, official deadlines and a full resolution workspace — tasks, documents, filings and closure verification.
Discover properties with publicly documented issues in your specialties and territories. Every opportunity is labelled honestly: public-record signal, verified service need, or owner-requested quote.
A downloadable compliance and maintenance history that clearly separates official public records, customer-provided documentation, automated analysis and AI-generated summaries.
Official sources
PROPERTY OS reads published NYC Open Data datasets through their documented APIs, preserves every original record, and links each figure back to its source row. Statuses are shown exactly as recorded — OPEN, CLOSED, PENDING VERIFICATION or UNKNOWN.
Addresses resolve to tax lots (BBL) and buildings (BIN). A lot can hold several buildings; an address can exist in more than one borough. We never assume a one-to-one match.
Operating principles
No record never means no problem. Gaps and unavailable sources are shown, not hidden.
Risk and opportunity scores list every contributing factor and the records behind it.
Your workflow never changes a government status. Closure is verified against the agency record.
AI summaries cite the records they use and are validated; outputs that introduce dates, amounts or statuses are held for human review.
Organization data is separated with database row-level security in addition to server-side checks.
Contractor licenses and insurance are shown as verified only after review against the issuing authority.
Monitor two buildings free during evaluation.
