The statutory notice is not a test result
Florida Statutes section 404.056 contains radon notification language for covered real-estate documents. The notice describes radon risk and the existence of additional information; it does not state that the building was tested or predict its concentration. Use the current statutory text and transaction documents rather than a paraphrase from this website.
Build the testing plan around the deadline
EPA’s buyer-and-seller material describes a minimum 48-hour test for many real-estate measurements, while some devices require longer. For a two-to-four-day test, closed-house conditions begin at least 12 hours before the test and continue during it. The device instructions and applicable protocol control.
Agree on the protocol
Method, test location, timing, closed-house conditions and who may enter the property.
Protect the measurement
Document conditions and use appropriate interference controls without making the house artificially sealed.
Use the contract
Testing rights, deadlines and any response belong to the parties’ documents and professional advice—not a presumed local custom.
DIY acceptance is a transaction question
A consumer test can be useful for a homeowner. Whether a self-run result is acceptable for a buyer, seller, lender, insurer or another party depends on the decision and documents. When independence or defensibility matters, verify a Florida-certified measurement business.
