Records to check before you buy in Jackson County

• Property record card — the Jackson County assessor / appraisal office. Pull the parcel's assessed-value history, exemption status, and last sale. This is the file your future tax bill is calculated from, and it shows whether the current owner is enjoying exemptions you will not inherit. County government sits in Kadoka — start there for office locations and the parcel search.
• Deeds & liens — the Jackson County recorder / land-records office. Read the deed chain, open liens, easements, and plat maps — the file a listing never mentions.
• Official flood determination. Check the exact parcel on FEMA's National Flood Hazard Layer — not the listing site's licensed model. Zone boundaries cut through streets; the house next door can be in a different zone. Jackson County is the primary county for 4 ZIP codes in the Census Bureau's ZIP-to-county crosswalk — and zone lines ignore every one of them.
• The county's reported-crime record. In the FBI's 2024 file, agencies in Jackson County reported 16 offenses — 5.85 per 1,000 residents; the largest single category was larceny-theft (9). The crime section below sets that beside the South Dakota county median.
• Registry check. Run the address through South Dakota Sex Offender Registry (South Dakota Division of Criminal Investigation (Attorney General)) and note the counts within a mile — then check again the week you close.
• Permits & code history — the Jackson building department. Open permits, expired permits, and code cases tell you whether the renovation in the photos was ever inspected. County permitting is run out of Kadoka.
• School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.
