Every property record, violation, permit, and document in RegWatch comes directly from official government databases. Here's the full catalog — with links to verify each source yourself.
39 sources · Deep coverage in tri-state (NY · NJ · CT) · Standard federal coverage · 8 expansion states · 39 more on roadmap
RegWatch aggregates 39 authoritative government data sources into a single property search. Deep coverage spans the tri-state (NY/NJ/CT — multiple agency feeds per state), plus standard federal coverage (FEMA, EPA, HUD, USGS, Census) and parcel-level coverage in eight expansion states (FL, NC, WA, MD, OR, CA, IN, TN). Each source links to its authoritative government portal so you can verify any record at its source.

RegWatch integrates with 39 authoritative government sources across New York City (11 agencies), New York State, New Jersey, Connecticut, and U.S. federal agencies. Every property record, violation, permit, title document, tax assessment, zoning designation, and environmental hazard flag in a RegWatch report is sourced directly from one of these official sources.
Each source has a refresh cadence appropriate to how often the underlying government system publishes. Critical operational records (permits, violations, deeds) refresh on a Live cadence — typically within a day of agency publication. Assessment and landmark designations follow a Scheduled cadence (monthly or weekly). Statewide rolls and federal environmental data refresh on a Periodic cadence. Every record in a RegWatch report includes a "last verified" timestamp so you know exactly how fresh it is.
Yes — that's the point of this page. Every source listed here links directly to the original government portal. If you want to verify a specific record, click through to the authoritative source and check there. RegWatch's job is to aggregate, normalize, and cross-reference these records — not to replace the authoritative source.
Property records are a YMYL (Your Money or Your Life) category — people make six- and seven-figure decisions based on this data. Source transparency is non-negotiable for trust. It also helps search engines and AI assistants cite the correct underlying record when they reference RegWatch content.
Active expansion targets include deeper agency feeds in the eight expansion states (FL, NC, WA, MD, OR, CA, IN, TN — currently parcel + assessment only), federal IRS lien/bankruptcy filings, enhanced SEC/EPA environmental records, and additional municipal-level feeds in the tri-state area. Follow our blog or check the /state/[code] pages for each state's current coverage status.
Each agency maintains its own search portal, login flow, data format, and refresh cadence. Running proper property diligence through each of them manually takes 4–6 hours per address. RegWatch unifies them into a single address search that returns a complete report in seconds, with cross-referenced records (e.g., DOB violations linked to their ECB hearings and any resulting liens).
