Fort Collins sits in Larimer County, an area known for elevated indoor radon levels due to the region’s geology. The U.S. EPA and Colorado Department of Public Health and Environment both classify much of northern Colorado as Zone 1, meaning predicted average indoor radon levels exceed 4 pCi/L. Homebuyers, real estate agents, and long‑term residents in Fort Collins routinely request radon testing before property transactions, after mitigation, or as part of healthy home maintenance. The local housing market remains active, with many older homes and new constructions that require testing for compliance with Colorado’s Radon Resistant New Construction (RRNC) code. Additionally, the city’s health‑conscious culture creates strong demand for mitigation‑aware services. A radon testing business here can thrive by offering both short‑term charcoal tests and continuous digital monitoring, with a focus on reliability, quick turnaround, and clear reporting.
Colorado does not currently require a state‑level radon testing license for professionals who perform only testing. However, anyone offering mitigation services must be certified by the Colorado Department of Public Health and Environment (CDPHE) or hold a national certification (e.g., NRPP or NRSB). For testing alone, voluntary certification builds credibility. Obtain a National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB) certification to assure clients that you follow industry standards (ASTM E2121 or EPA protocols).
Register your business with the Colorado Secretary of State (choose an LLC or sole proprietorship). Obtain a City of Fort Collins business license; apply through the City’s Sales Tax License and Business Registration portal. If you employ staff, you must register for unemployment insurance and workers’ compensation through the Colorado Department of Labor and Employment. A sales tax license is required if you sell tangible items (e.g., test kits) from a physical location; most testing services are considered taxable services under Colorado law, so collect and remit state and city sales tax (Fort Collins rate: 8.85% as of 2025).
Fort Collins adopted the 2021 International Residential Code (IRC) Appendix F, which mandates passive radon systems in new homes. Builders often hire certified testers to verify post‑construction radon levels. Familiarize yourself with this code to offer new‑construction testing services.

Pre‑populate common questions and answers: “How long does a radon test take?” (48 hours for short‑term), “Do you test after mitigation?” (yes), “What areas do you cover?” (Fort Collins, Loveland, Wellington, Timnath). This preemptive content boosts local relevance.

Radon testing is a trust‑based service. Aim for at least 20 Google reviews with keywords like “thorough,” “prompt,” “clear report.” Send a follow‑up email after each test with a link to leave a review. Respond to negative reviews professionally, offering to re‑test if there’s a dispute. Positive reviews on Google, Yelp, and Facebook directly influence local pack rankings.
