Records to check before you buy in Harrison County

• Property record card — the Harrison 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 Biloxi; the official county website is the reliable route to the parcel search and the office directory.
• Deeds & liens — the Harrison 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. Harrison County is the primary county for 11 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 Harrison County reported 6,628 offenses — 31.01 per 1,000 residents; the largest single category was larceny-theft (4,960). The crime section below sets that beside the Mississippi county median.
• Registry check. Run the address through Mississippi Sex Offender Registry (Mississippi Department of Public Safety, Criminal Information Center (Mississippi Sex Offender Registration)) and note the counts within a mile — then check again the week you close.
• Permits & code history — the Harrison 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 Biloxi.
• School assignment — the district office, not the listing. Only the district's own boundary lookup confirms which school an address is actually zoned for.

Reported crime in Harrison County — FBI 2024

Reported crime in Harrison County in 2024 was overwhelmingly property crime: agencies logged 6,628 offenses, of which 5,912 were property offenses and 716 violent. The total rate is 31.01 per 1,000 residents (violent 335.0, property 2766.1 per 100,000).

Inside Mississippi, the median county in the same file recorded a violent-crime rate of 121 per 100,000 and a property-crime rate of 524 per 100,000 (medians computed from the FBI 2024 county file across 82 counties).

The largest reported categories were larceny-theft (4,960), burglary (572) and aggravated assault (551).

Coverage: 9 of 9 law-enforcement agencies assigned to this county reported at least one month of 2024 offense data to the FBI; 6 reported all 12 months. 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. MS had incomplete agency reporting statewide in 2024: reported offenses equal about 63% of the FBI's estimated state total at the low end (violent 63%, property 63%), so this county's counts and rates likely understate 2024 totals.

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.
