- NJ doesn't require a radon test to sell a home, but buyers commonly test during the inspection period.
- Businesses that test for or mitigate radon must be certified by NJDEP (N.J.A.C. 7:28-27). Ask for the business's and the individual's DEP certification numbers (NJDEP Radon Business Certification; Radon Section 800-648-0394).
- DIY kits should carry a NJ certification number starting with MEB9 (NJDEP).
- Disclosure: NJ law requires that radon test and mitigation information be given to the buyer (N.J.S.A. 26:2D-73) confirm with town: statute section not re-checked for this draft.
We don't list radon business yet. NJDEP publishes the official list through its own lookup tool: https://dep.nj.gov/rpp/radon/radon_bus/. Providers can ask to be listed; we would verify against the official record.
