Radon in Space Coast Homes: What Brevard County FL Buyers Should Know

Do Space Coast homes need to be tested for radon?

Florida requires a radon disclosure on every home sale contract in Brevard County, but it does not require testing. Radon is measured in picocuries per liter, and the EPA recommends fixing any home that tests at 4.0 pCi/L or higher.

Radon comes up in almost every Space Coast purchase contract and almost never comes up in conversation. Buyers sign the disclosure at the same moment they are signing twelve other things, skim past the paragraph, and move on. Then a few weeks later an inspector mentions radon and the whole thing feels like it came out of nowhere.

Here is the short version for anyone buying in Melbourne, Merritt Island, Viera, or anywhere else in Brevard County: the disclosure is mandatory, the test is optional, and the test is cheap enough that skipping it is a strange place to save money.

What is radon, and why does Florida care about it?

Radon is a naturally occurring radioactive gas produced as uranium in soil and rock breaks down. It has no color, no smell, and no taste. Outdoors it disperses harmlessly. Indoors it can accumulate, and long-term exposure at elevated levels is associated with increased lung cancer risk.

Because it comes up out of the ground, radon enters a home through the slab, through cracks, through utility penetrations, and through the joints where the foundation meets the walls. That means the question is about a specific building, not a specific neighborhood. Two houses on the same street in Rockledge can test very differently.

Does Florida require a radon disclosure on a Space Coast home sale?

Yes. Under section 404.056(5) of the Florida Statutes, a specific radon gas notice has to be provided at or before the time a contract for sale and purchase of a building is executed. The same requirement applies to rental agreements. The notice tells the reader what radon is, states that levels exceeding federal and state guidelines have been found in buildings in Florida, and points people to their county health department for more information.

Two things that surprise buyers about this rule:

• It is a disclosure requirement, not a testing or remediation requirement. Nobody has to test, and no seller in Brevard County has to fix anything because of it.
• It does not apply to unimproved property. Buying a vacant lot in Viera or Merritt Island does not trigger the notice, because there is no building.

What radon level is considered elevated?

The EPA action level is the number to anchor on. Here is how the ranges break out:

Result	What EPA recommends
4.0 pCi/L or higher	Fix the home
Between 2.0 and 4.0 pCi/L	Consider fixing the home
Below 2.0 pCi/L	No action recommended

For context, EPA puts the average indoor radon concentration in American homes at roughly 1.3 pCi/L, and average outdoor air at about 0.4 pCi/L. There is no level considered completely risk free, which is why the 2.0 to 4.0 band carries a "consider" rather than a "no."

How do you test for radon on the Space Coast?

Testing during a real estate transaction is normally a short-term test placed in the lowest lived-in level of the home, left in position for a set number of days, then sent to a lab. Florida certifies radon measurement businesses, and the Florida Department of Health maintains the certification program. Ask your inspector whether radon measurement is part of their scope or a separate certified vendor, because on the Space Coast it is frequently the latter.

Timing matters in a Brevard County transaction. Short-term tests need the house closed up, which means coordinating access with the seller and building the days into your inspection period rather than discovering on day nine that you needed to start on day one.

Can you look up radon results by Brevard County zip code?

You can, with a caveat. The Florida Department of Health publishes a database of radon test results reported by certified radon businesses under the same statute that requires the disclosure. You can search it by zip code, which covers Melbourne, Merritt Island, Rockledge, Cocoa Beach, Satellite Beach, and every other part of the Space Coast.

The caveat is important, and the Department of Health states it plainly: the data is not a scientific or statistical survey. It only reflects buildings that happened to be tested and reported. A zip code with a handful of results tells you almost nothing about the house you are actually buying. Use it for background, not for a decision.

What happens if a Space Coast home tests high?

Radon mitigation is a well-established fix, and it is usually less dramatic than buyers expect. A typical system depressurizes the soil under the slab and vents it above the roofline with a fan and a run of pipe. Florida certifies radon mitigation businesses in the same program that certifies measurement businesses.

From a negotiating standpoint, an elevated result in Brevard County is a normal thing to bring back to the seller. It is a defined problem with a defined fix and a quotable price, which is exactly the kind of item that gets resolved rather than blowing up a contract. The Florida Department of Health's radon page for real estate is the reference to send a seller who has never heard of any of this.

Frequently asked questions

Is radon a problem in Brevard County FL?

Radon is building specific, not neighborhood specific, so there is no honest way to answer that for a whole county. Elevated results have been found in buildings across Florida, and the only way to know about a particular Space Coast home is to test that home. Anyone who tells you a Brevard County zip code is safe or unsafe is guessing.

Who pays for a radon test in a Space Coast transaction?

It is normally a buyer-paid inspection item in Brevard County, the same as a wind mitigation inspection or a four point inspection. It is one of the less expensive items on the list, which is part of why it is worth ordering.

Does new construction in Viera or Melbourne need a radon test?

New construction is not exempt from radon. A newly built home in Viera can test elevated just like a 1970s home in Melbourne, because the driver is the soil and the slab, not the age of the house. If radon matters to you, test the house regardless of the year it was built.

None of this should scare you off a house. It should just get handled on purpose instead of by accident, which is true of most things in a Space Coast transaction.
