What to check before buying land in Cochise County

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

  1. 1.Budget for a perc test and maybe an engineered septic

    USDA rates 88% of Cochise County's mapped soils "very limited" for conventional septic absorption fields and 3.1% "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.

  2. 2.Prove the water supply before you buy

    At least half of Cochise County was in severe drought (D2) or worse in 37% of the 262 weekly U.S. Drought Monitor maps from 2021 to 2026. Arizona allocates water by permit or water right, so a well or pond isn't automatic.

    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.

    Guide: Wells, public water and water rights

  3. 3.Check wildfire exposure and insurance

    FEMA rates Cochise County's wildfire risk relatively high, and 2.9% 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.

  4. 4.Check slope where you'd build and where the driveway goes

    35% of Cochise County's mapped soils have an average slope over 15% (USDA SSURGO).

    Steep ground means grading, retaining walls, longer driveways and erosion control. Compare the slope at the house site and along the access route, not just the parcel average.

    Guide: Terrain and slope

  5. 5.Confirm legal road access and power

    The 2020 Census classified 99% of Cochise 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.

  6. 6.Confirm the flood zone at your exact spot

    1.6% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 5.8% of its mapped soils flood occasionally or frequently. FEMA rates Cochise County's river-flooding risk relatively high.

    Even where little of the county floods, creeks and low spots do. Check the FEMA zone at the building site and the driveway route.

The floodplain share is the area FEMA's National Risk Index counts as exposed to inland flooding, mostly mapped 100-year flood zones. It says how common flood-prone land is in Cochise County, not whether a given parcel floods. For that, look up the zone at your exact point on the FEMA Flood Map Service Center or run the free check.

Questions about buying land in Cochise County

How much of Cochise County, AZ is in a flood zone?

About 1.6% of Cochise County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 5th highest of 15 counties in Arizona. 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 Cochise County?

The 2022 Census of Agriculture put the average value of farm land and buildings in Cochise County at $2,695 an acre, 4th highest of 15 counties in Arizona (the median Arizona county was $2,148). 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 Cochise County?

Often, but test first. USDA soil surveys rate 88% of Cochise 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 Cochise County?

0% of Cochise County's mapped soils are prime farmland, 11% 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 1,002 farms averaging 1,034 acres.

How often is Cochise County in drought?

Since 2021, at least half of the county was in severe drought or worse in 37% of weekly U.S. Drought Monitor maps, and in extreme drought in 16%. 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 Cochise 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 Cochise 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.
