What to check before buying land in Pinellas County
Ordered by what Pinellas County's numbers point to. Every parcel differs, so treat this as where to look first.
1.Put flood checks first in Pinellas County
18% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 6.5% is exposed to coastal flooding; 5.2% of its mapped soils flood occasionally or frequently. FEMA rates Pinellas County's river-flooding risk relatively high.
Look up the FEMA flood zone at the pin, not the parcel's address. If any of the land is in zone A or V, price flood insurance before you offer, ask for an elevation certificate, and check whether the access road floods too.
2.Expect wetlands; map them before you plan
About 11% of Pinellas County's mapped soils are hydric (formed under saturated conditions, a federal wetland indicator) and 59% are poorly or very poorly drained (USDA SSURGO).
Open the National Wetlands Inventory mapper at the parcel. Filling or draining a wetland can need a Clean Water Act Section 404 permit, and wet ground limits septic fields and building pads.
3.Budget for a perc test and maybe an engineered septic
USDA rates 100% of Pinellas County's mapped soils "very limited" for conventional septic absorption fields and 0% "not limited".
Without city sewer you need a septic permit from the county or state health department. Make the offer contingent on a passing soil or perc test; mound and aerobic systems can cost several times a conventional one.
4.Prove the water supply before you buy
At least half of Pinellas County was in severe drought (D2) or worse in 31% of the 262 weekly U.S. Drought Monitor maps from 2021 to 2026.
Ask whether the land has a public water connection, an existing well (and its log and yield), or neighbors' well depths from the state well database. For a new well, check permits and typical depth with the state agency first.
5.Sanity-check the price per acre
Farm real estate in Pinellas County averaged $25,955 an acre including buildings in the 2022 Census of Agriculture, and 0% of its mapped soils are prime or of statewide importance.
Compare the asking price with recent sales of similar tracts, not the county average, which mixes cropland, pasture, timber and homesites. If an ag tax valuation applies, ask what the rollback taxes would be if you change the use.
6.Confirm access, utilities and zoning
The 2020 Census classified 7.3% of Pinellas County's land area as rural.
Rural tracts are often sold without recorded access or a power line nearby. Get the title company to confirm a recorded easement or public road frontage, and ask the electric co-op what a line extension costs.

Questions about buying land in Pinellas County
How much of Pinellas County, FL is in a flood zone?
About 18% of Pinellas County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 8th highest of 67 counties in Florida. Another 6.5% is exposed to coastal flooding. Whether a given parcel is in a flood zone depends on its exact location, so check the FEMA map at your pin.
How much does land cost per acre in Pinellas County?
The 2022 Census of Agriculture put the average value of farm land and buildings in Pinellas County at $25,955 an acre, 3rd highest of 65 counties in Florida (the median Florida county was $6,645). It's a self-reported average across farms, so small homesites and recreational tracts often sell for more per acre.
Will a septic system work on land in Pinellas County?
Often, but test first. USDA soil surveys rate 100% of Pinellas County's mapped soils very limited for conventional septic absorption fields, usually because of wetness, slow permeability, shallow rock or flooding. A perc or soil test on the parcel decides what system the health department will permit.
Is there good farmland in Pinellas County?
0% of Pinellas County's mapped soils are prime farmland, 0% are prime only if drained, irrigated or protected from flooding, and 0% are farmland of statewide importance (USDA SSURGO). The 2022 Census of Agriculture counted 115 farms averaging 33 acres.
How often is Pinellas County in drought?
Since 2021, at least half of the county was in severe drought or worse in 31% of weekly U.S. Drought Monitor maps, and in extreme drought in 15%. On 2026-10-27, 100% of the county was in moderate drought or worse.

Check the parcel, not just the county
County numbers tell you what to look for. The free check looks at your exact point in Pinellas County: flood zone, slope, soils, wetlands, roads, power and more. The full report is $29.
What these numbers can't tell you
- County shares describe Pinellas County as a whole; a parcel can be entirely in or out of a flood zone, wetland or poor soil.
- It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
- It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
- It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
- Maps lag behind the ground, and distances are straight-line, not driving distance.
