Austin’s real estate market remains one of the fastest-growing in the country, with thousands of homes changing hands each year. Radon – a cancer‑causing radioactive gas that seeps into buildings from the soil – is a growing concern among homebuyers and sellers in Central Texas. While much of the national conversation focuses on regions with high baseline radon, the Texas Department of State Health Services (TDSHS) classifies large parts of Travis County and surrounding counties as Zone 1 or Zone 2 areas, meaning average indoor radon levels can exceed four picocuries per liter (pCi/L).
Local home inspectors, real estate agents, and property managers in Austin are increasingly recommending radon testing during transactions. The Austin‑Round Rock metro area alone sees over 35,000 existing‑home sales per year, creating a steady stream of testing opportunities. Additionally, many multifamily landlords and commercial property owners are becoming proactive about testing to protect tenants and avoid liability. For a startup, the timing is favorable: awareness is rising, but the market is still fragmented – few full‑time radon specialists serve the entire Austin metro, leaving room for a focused, well‑marketed business.
Texas does not have a state‑mandated license for radon testing or mitigation. However, to operate credibly and to meet the requirements of most real estate contracts, you should obtain certification from a nationally recognized program. The most respected are the National Radon Proficiency Program (NRPP) and the American Association of Radon Scientists and Technologists (AARST). Certification typically involves completing an accredited course, passing an exam, and agreeing to a code of ethics.
In addition to certification, you must register your business with the Texas Secretary of State (if you choose an LLC or corporation) and obtain an Employer Identification Number (EIN) from the IRS. The City of Austin requires a general business license for any home‑based or commercial service business; you can apply online through the Austin Finance Department. Check with Travis County if you operate outside city limits. For homeowners’ association (HOA) compliance, remember that many Austin suburbs require you to carry general liability insurance (at least $1 million is standard) and, if you perform mitigation work, pollution liability coverage. Finally, because you’ll be entering homes, a background check and a simple surety bond are not required by law but can build trust with customers.
Radon testing services are generally considered a nontaxable service in Texas, but if you sell testing devices (like long‑term test kits) separately, those sales are subject to state and local sales tax (8.25% in Austin). Consult a CPA to verify your specific situation.
