What to check before buying land in Indian River County

Ordered by what Indian River County's numbers point to. Every parcel differs, so treat this as where to look first.

  1. 1.Put flood checks first in Indian River County

    29% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 2% is exposed to coastal flooding; 1.6% of its mapped soils flood occasionally or frequently.

    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. 2.Expect wetlands; map them before you plan

    About 62% of Indian River County's mapped soils are hydric (formed under saturated conditions, a federal wetland indicator) and 94% 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. 3.Budget for a perc test and maybe an engineered septic

    USDA rates 100% of Indian River 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.

    Guide: Perc tests and septic systems

  4. 4.Confirm legal road access and power

    The 2020 Census classified 82% of Indian River 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.

  5. 5.Check wildfire exposure and insurance

    FEMA rates Indian River County's wildfire risk relatively low, and 17% of the county's area is in the wildfire exposure zone the National Risk Index uses.

    Ask an insurer for a quote early; some carriers won't write new policies in high-hazard areas. Check access for fire trucks, nearby fire stations and the vegetation around the building site.

  6. 6.Find out where the water comes from

    At least half of Indian River County was in severe drought (D2) or worse in 9.5% 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.

Questions about buying land in Indian River County

How much of Indian River County, FL is in a flood zone?

About 29% of Indian River County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), the highest of 67 counties in Florida. Another 2% 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 Indian River County?

The 2022 Census of Agriculture put the average value of farm land and buildings in Indian River County at $6,645 an acre, 33rd lowest 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 Indian River County?

Often, but test first. USDA soil surveys rate 100% of Indian River 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 Indian River County?

0% of Indian River 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 492 farms averaging 340 acres.

How often is Indian River County in drought?

Since 2021, at least half of the county was in severe drought or worse in 9.5% of weekly U.S. Drought Monitor maps, and in extreme drought in 3.1%. On 2026-10-27, 0% 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 Indian River 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 Indian River 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.
