Reno sits in Washoe County, an area with moderate to high radon potential according to the U.S. Environmental Protection Agency and the Nevada Radon Education Program. The region’s geology – granitic soils from the Sierra Nevada and volcanic deposits in the Truckee Meadows – creates natural uranium decay that releases radon gas. Many homes in Reno, especially those built before 2010, have not been tested for radon. The winter months (November through February) are the most critical testing period because homes are sealed tightly, trapping radon inside.
The real estate market in Reno is active, with a mix of older homes and new construction. Radon testing is increasingly required during real estate transactions. Buyers are becoming more educated about radon risks, and many home inspectors now include radon tests as a standard service. This creates a strong demand for independent radon testing companies that can offer quick turnaround, accurate results, and mitigation referrals.
Competition exists but is not saturated. There are a handful of established mitigation companies and a few testing-only businesses. A new entrant can differentiate by focusing on speed, clear reporting, and customer education. The local health district and the Nevada Division of Environmental Protection (NDEP) also promote radon awareness, so community trust is high for certified professionals.
Nevada does not have a state-level radon certification program. However, the Nevada Radon Education Program (operated by University of Nevada Cooperative Extension) strongly recommends that testers hold a National Radon Proficiency Program (NRPP) certification or a National Radon Safety Board (NRSB) certification. These are nationally recognized credentials. To test homes in Reno, you must be NRPP or NRSB certified for measurement services. Testing without certification may void the test results for real estate transactions and can lead to liability issues.
You must register your business with the Nevada Secretary of State and obtain a local business license from the City of Reno or Washoe County, depending on your service area. If you operate solely within Reno city limits, apply for a City of Reno Business License. If you serve unincorporated Washoe County, apply for a Washoe County Business License. As of 2025, the fee is approximately $100-$200 per year. You will also need a Nevada State Business License (from the Department of Taxation) if your gross revenue exceeds $4,000 per quarter.
General liability insurance is essential. Radon testing equipment is sensitive, and clients may claim damage or incorrect results. Consider errors and omissions insurance specific to environmental testing. Minimum coverage of $1 million is typical for real estate work.
Nevada does not require mandatory radon disclosure in real estate transactions, but the test results become part of the property disclosure if conducted. You must provide clear, written reports that comply with EPA protocols. Always include the EPA action level of 4 pCi/L and recommend mitigation if results exceed that threshold.
