How Commercial Radon Testing Works
Four steps from site assessment to written compliance report.
Site Assessment
We review your Sioux Falls building's footprint, occupied zones, HVAC system, and foundation type to design a multi-point protocol appropriate for the property.
Multi-Point Placement
Testing devices are placed at multiple locations on the lowest occupied level — covering different zones to document results across the full building footprint.
Test Period
Devices remain in place for the required duration under closed-building conditions. We coordinate with building management to minimize disruption to daily operations.
Compliance Report
Results from the certified lab are compiled into a written compliance report showing results at each test point with EPA context and recommended next steps.
Sioux Falls Commercial Testing Context
Why Sioux Falls Commercial Buildings Need Radon Testing
The Sioux Falls metro has grown substantially — office parks in the northwest corridor, medical campuses on the city's expanding edges, and growing industrial and retail zones in Harrisburg, Tea, and Brandon all sit in Zone 1 territory. The EPA's 4.0 pCi/L action level applies equally to every commercial space where workers spend significant time at or below grade.
Schools and daycares serving the metro are among the most common commercial properties where radon testing is warranted — occupants are often young children spending extended time in classrooms at ground level. Medical clinics, office parks, and any building with below-grade occupied space have similar exposure considerations. A single-point residential approach doesn't adequately represent a commercial footprint; multi-point placement is necessary to document the actual range of conditions across the building.
The written compliance report we provide is suitable for building owners, property managers, employers with occupational health programs, commercial real estate due diligence, or lease requirements. If any location exceeds 4.0 pCi/L, we discuss next steps — commercial mitigation is available and effective.

Commercial Radon Testing in Sioux Falls — FAQ
Yes. The EPA's 4.0 pCi/L action level applies to any occupied space — offices, schools, daycares, clinics, or residences. Sioux Falls and Minnehaha County are Zone 1, meaning elevated radon potential applies across all property types in the area. Any building with ground-floor or below-grade occupied space is a candidate for testing.
Any Sioux Falls building where workers or occupants spend significant time at or near ground level warrants testing. This includes office parks throughout the metro, medical offices and clinics, schools and daycares, retail spaces, and industrial facilities. Multi-story buildings should be tested on the lowest occupied floor.
Commercial buildings have larger footprints, more varied HVAC systems, and different airflow patterns than residential properties. A single test device doesn't adequately represent the range of conditions across a commercial space. We use multi-point placement — multiple devices at different locations on the lowest occupied level — to document actual spatial variation throughout the building footprint.
The written report documents radon levels at each test location in your Sioux Falls building, compares them to the EPA's 4.0 pCi/L standard, and provides guidance on next steps if any location requires action. Suitable for building owners, property managers, employers, commercial real estate transactions, or occupational health programs.
