Commercial radon mitigation system installed on a Sioux Falls office building

Different building, different standard, different paperwork. Commercial and multifamily radon work follows ANSI/AARST protocols rather than the residential ones, and the deliverable is usually as much about the documentation as the hardware. Daycare licensing, school district policy, an insurer, a lender, or a corporate tenant's environmental review will each ask for something slightly different, and it helps to know which one is driving the request before anybody starts measuring.

Measurement is the part that gets underestimated

A house needs one test. A building needs a test in every ground-contact room that people occupy, which in a school or a clinic is a lot of devices placed at once and collected on a schedule. Buildings also have mechanical ventilation that changes pressure relationships between zones, so a wing that reads fine with the HVAC running can read very differently on a weekend setback. Measurement plans for commercial buildings account for that. Single spot checks in a hallway do not.

Design follows the building, not a template

Slab-on-grade with a large footprint frequently needs multiple suction points on a manifold rather than one big fan. Buildings with elevator pits, utility tunnels or below-grade mechanical rooms have pathways a residential installer will walk right past. Where the HVAC can be rebalanced to hold ground-contact zones at slight positive pressure, sometimes part of the fix is mechanical rather than a new system at all, and that conversation belongs with your HVAC contractor in the room.

What we hand you at the end

Pre-mitigation measurement data by zone, the system design and as-built, fan specifications and locations, post-mitigation results by zone, and a recommended retest interval. Formatted to go straight into a compliance file. Multifamily owners also get a short written explanation suitable for handing to tenants, because the question always comes and it is better answered on paper than at a door.

Are South Dakota schools and daycares required to test for radon?

South Dakota does not mandate radon testing in schools or childcare facilities. Testing is commonly driven by district policy, licensing bodies, insurers or lenders rather than by state law, and it is worth confirming which of those is asking before scoping the work.

How disruptive is commercial radon mitigation?

Most of it happens in mechanical spaces and above ceilings, and coring is scheduled for off-hours. On school and daycare projects we work around the calendar, which usually means summer or a break week.

How often should a commercial building retest?

Every two years is a common interval, plus after any major HVAC modification, building addition, or change in how ground-contact space is used. Converting a storage level into offices changes the exposure picture entirely.
