Test Brevard County, FL once anyway - radon varies house to house

The predicted basement average here is 1.3 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Brevard

The typical Brevard County home is predicted below 2 pCi/L, the lowest band. That is the best case an area can show - but it describes the average house, and the ZIP-level predictions within the county still span 1.0 to 1.5 pCi/L.

The 1993 EPA zone (3) and the 2001-2021 model agree for Brevard. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.

Comparable Florida counties: Bradford County (1.3), Escambia County (1.3), Lake County (1.3), Liberty County (1.3). The state's highest is Jefferson County at 1.6 pCi/L.

Mitigation is a routine job: a fan-driven pipe that vents soil gas from under the slab to above the roofline, typically $800-$2,500 installed (typical range; local quotes vary). Use certified professionals: EPA find-a-professional. Read the full mitigation guide.

Brevard County radon questions

Is radon high in Brevard County, Florida?
Low. The model predicts a long-term basement average of 1.3 pCi/L in Brevard County (about 28% below the US average of 1.8 and close to the Florida average of 1.3). That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Ranked 42 of 67 Florida counties.
Should I test for radon in Brevard County?
Yes, once. The EPA recommends testing every home regardless of area, and the model's ZIP-level predictions in Brevard County already range from 1.0 to 1.5 pCi/L. A short-term kit costs little and settles the question for your house.
What does EPA Radon Zone 3 mean for Brevard County?
Zone 3 - low potential (< 2 pCi/L). The zone map dates from 1993 and classifies whole counties. The 2001-2021 model agrees with the zone here. Neither replaces a test of your own home.
How much does radon mitigation cost in Brevard County?
A standard active sub-slab depressurization system typically runs $800-$2,500 installed nationally; Florida quotes vary with foundation type (slab, crawlspace, basement), home size and local labor. Get two or three bids from certified mitigators listed by your state radon program or the EPA's find-a-professional page.
