Hawaii is the eighth smallest state and the eleventh least populous. Oddly enough, it happens to be the 13th most densely populated out of the entire US.

The state does not have a dedicated radon program. You can find more information on radon, testing and mitigation here at RadonResources.com.

The radon levels in Hawaii are about average. Regardless, there’s an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

Hawaii Radon Levels

Map of Hawaii Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

Hawaii Radon Statistics

Hawaii has 5 counties and 0 (0%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. Hawaii's state radon zone average is 2.4, which is the average of all county zone ratings the EPA has assigned the state, ranking it 37 among all states.

Hawaii Radon Contractor License Information

Does Hawaii require contractors to be licensed? No.

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in Hawaii. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.

Hawaii Radon Real Estate Requirements

Does the state of Hawaii require radon testing for all real estate transactions? No

However both the state of Hawaii and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though Hawaii does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. Hawaii radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
