From the county property appraiser, who maintains the parcel roll, and the clerk of court, who records deeds. Florida compiles appraiser rolls into a statewide cadastral file once a year, while permits, sales, and corporate filings update continuously. Anything built on the annual file alone is up to twelve months behind the record.
Who is the system of record for a parcel?
The county property appraiser. They maintain the parcel boundary, the ownership name and mailing address, the assessed and just values, and the building characteristics — year built, heated area, use code. Every commercial parcel product in the country ultimately derives from this office. County property appraiser, real property roll and GIS parcel layer
The clerk of the circuit court is the second system of record. Deeds, mortgages, liens, and plats are recorded there, which is what makes a sale legally visible. Clerk of the circuit court, official records index
What does the statewide file add?
Coverage and consistency. Florida's Department of Revenue collects every county's roll and republishes it in a common schema, so all 67 counties can be read the same way instead of one appraiser's field naming at a time.

The trade-off is timing. It is an annual compilation, so it is authoritative for structure and out of date for events.
How current is each source?
- Statewide cadastral file — annual. Excellent for the parcel fabric; up to twelve months behind on ownership.
- County appraiser roll and GIS — typically continuous through the year, with the roll certified annually.
- Clerk's official records — effectively daily. A deed appears within days of recording.
- Permits and planning applications — as filed, and the earliest signal that a parcel is moving.
- Corporate registry filings — continuous, with annual reports concentrated in the first half of the year. Florida Division of Corporations (Sunbiz)
Why does refresh cadence change the answer?
Because the parcels worth your attention are the ones changing state. A map refreshed annually is reliable about geometry and unreliable about exactly the fields that decide whether a parcel is still available.
The practical failure is not a wrong boundary. It is calling an owner who sold nine months ago, or underwriting a site that already has an approved site plan.
How should a county map be rebuilt?
On a fixed cadence, from the sources directly, with each field carrying the source it came from:
- Take the parcel fabric from the appraiser or statewide cadastre.
- Overlay zoning and future land use from the county's adopted layers.
- Refresh sales from the clerk's records and activity from permit portals.
- Resolve entity owners through the corporate registry.
- Recompute capacity with one constant method, so parcels stay comparable.
Parcelrow runs exactly this loop every Monday across its live counties, and every field on the map traces to the source it came from. Parcelrow, weekly rebuild across 75,736 parcels and 1,498 tracked pipeline projects

Common questions
- Is county parcel data free?
- The underlying records are public and most counties publish bulk exports or GIS services at no cost. The work — and the cost — is in joining sources that do not share a key, refreshing them on their own cadences, and keeping the result usable.
- Why do two parcel sources disagree about the same property?
- Usually timing. The statewide file is an annual snapshot, while the appraiser's own roll and the clerk's records update far more often. A sale recorded last month appears in the clerk's index long before it reaches the annual file.
- How current does a county map need to be?
- Current enough that a parcel which sold, permitted, or rezoned since your last look is not still presented as an opportunity. Parcelrow rebuilds each county weekly, which keeps the lag under a week for the fields that change most.
