Onondaga County, NY parcel owner data

181,895 parcels with the owner of record. 176,493 carry an owner mailing address (97%), and 55,441 of those are absentee — the list investors mail first. Browsing is free and unlimited on the map; one credit turns any owner into a verified phone and email, and only if one comes back.

What a county file actually lands at. 3,642 of these rows (2%) are owned by a government body, a school or water district, a church, a cemetery or an HOA, and every list pull strips them — so a Onondaga County file arrives at about 178,253 mailable rows, not 181,895. That is the number to price against.

Why out-of-state is near zero here. That flag is read from the two-letter state before the ZIP at the end of the mailing address. Onondaga County publishes most of its mailing addresses without a trailing state and ZIP, so the filter can only confirm 1. That is the filter's real answer for this county, not a rounding — an out-of-state pull here will come back nearly empty, and absentee is the flag to use instead.

What Onondaga County publishes

A county is only as useful as the columns it fills in. This is measured on the rows themselves, not promised: how many of this county's 181,895 parcels carry each field.

Not in the record — for any county

  • Sale date, sale price, transfer history
  • Mortgage, lien, foreclosure or tax-delinquent status
  • Equity (there is no total value to subtract from)
  • Year built, square footage, beds and baths
  • Flood, wetlands, landlocked or road-frontage flags
  • Owner phone and email — those are traced on request, never stored on the parcel

Twelve real rows

Drawn deterministically by a hash of each row's own key, so these are the same twelve rows on every render and they spread across the county rather than down one street. Government, school, church and HOA owners are excluded, the way they are in a pull.

Public record data as published by the county. Phone and email are never shown here; they are resolved per owner, on request, with a right-party score.

What you can do with Onondaga County owner data

Pull every absentee owner in a ZIP and export the mailing addresses for a direct-mail campaign. Draw a box around a subdivision on the map and skip-trace the whole block in one job. Look up who owns the lot next to a listing, then call them with a scored number instead of sending a letter that gets thrown away.

Where the data comes from

Parcel boundaries, owner of record and mailing addresses are public records maintained by the county assessor or GIS office. Quarry pulls them from the county's own published services and refreshes on the county's cycle; the counts on this page were measured 2026-09-09. Phone and email come from the skip-trace engine, cross-checked across sources and scored, and you are only charged when a contact is found.
