§ 106790 Radon Testing Exemptions

This law says it does NOT apply to people who test or fix radon in their own building, design radon fixes for new construction, or do radon research as long as they tell the owner they aren't certified, the results aren't legal, and the methods are experimental.

Key Takeaways

  • •If you own or live in a building, testing or fixing radon there is exempt from this law.
  • •Designing or doing radon mitigation for brand‑new construction is also exempt.
  • •Researchers can be exempt, but only if they tell the building’s owner that they aren’t certified, the test results aren’t legal evidence, and the methods are experimental.

Example

A homeowner checks the radon level in their house and installs a radon mitigation system.

Because the person owns and lives in the building, the law does not cover them, so they don’t have to follow the usual certification rules.
