Records to check before you buy in Fairfield County

• Property record card — the Fairfield 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 Bridgeport — start there for office locations and the parcel search.
• Deeds & liens — the Fairfield 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. Fairfield County is the primary county for 46 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 Fairfield County reported 12,801 offenses — 13.34 per 1,000 residents; the largest single category was larceny-theft (8,265). The crime section below sets that beside the Connecticut county median.
• Registry check. Run the address through Connecticut Sex Offender Registry (Connecticut Department of Emergency Services and Public Protection (DESPP)) and note the counts within a mile — then check again the week you close.
• Permits & code history — the Fairfield 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 Bridgeport.
• School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.

Counts are reported offenses only (FBI Return A / Arson master files), assigned whole to each agency's primary county; they are not adjusted for non-reporting agencies. Population is the Census Bureau PEP 2021 estimate — the last PEP vintage published for Connecticut's historic counties.

These are offenses reported to law enforcement — not convictions, and not a verdict on any street or address. A CurbFacts report pairs this county record with the ZIP-level picture for the specific address you are buying.
