## What Does Commercial Radon Mitigation Involve?

Have you recently tested a large building and found elevated radon levels? Finding out your property has a radon problem can certainly add a stressful layer to your management duties or real estate transaction. You might be wondering how to fix a massive structure compared to a standard house.

We know exactly how overwhelming those commercial test results can feel. As an 

Iowa City radon company

[/ →](/)

 serving Central Iowa since 2016, our experts specialize in testing and installing Commercial Radon Systems for builders, property managers, and school districts. This specialized process requires a completely different approach than a single-family home.

Larger buildings require specialized, multi-suction-point systems balanced perfectly across massive concrete slabs. We handle the heavy lifting of planning these layouts and documenting the final results for lenders, boards, and building inspectors. Your project will stay perfectly compliant with the primary national codes:

-   **Multifamily Testing:** ANSI/AARST MAMF
-   **Multifamily Mitigation:** ANSI/AARST RMS-MF
-   **Schools & Large Buildings Testing:** ANSI/AARST MALB
-   **Schools & Large Buildings Mitigation:** ANSI/AARST RMS-LB

Our required test devices meet strict ANSI/AARST MS-PC performance specifications. Results from these devices hold up perfectly during a rigorous lender or board review. We will pick the exact right standard for your project and explain it to you in plain language.

Let’s walk through the exact types of commercial jobs we handle so you know what to expect.

## Which Projects Do We Handle?

### New construction

We support new construction projects with rough-in guidance, system activation, and pre-occupancy testing. Radon-resistant new construction (RRNC) puts a gravel layer, a sealed membrane, and a passive vent stack in place right before the concrete pour. Incorporating these features during the build phase is significantly cheaper than retrofitting a system later.

If pre-occupancy testing shows elevated levels, we add a specialized in-line fan to activate the stack. Up to 50% of passive stacks fail to reduce radon below the EPA action level of 4.0 pCi/L without mechanical help. Here is a quick look at the difference between the two setups:

| System Type | Primary Mechanism | Effectiveness | Best Use Case |
| --- | --- | --- | --- |
| Passive System | Natural thermal bypass (no fan) | Moderate | Initial new build phase |
| Active System | In-line mechanical exhaust fan | High (Up to 99% reduction) | Failed pre-occupancy tests |

You can read about

 for a great builder’s overview. Our experts also suggest reviewing 

passive vs. active radon systems

[/guide/passive-vs-active-radon-system/ →](/guide/passive-vs-active-radon-system/)

 to see why a passive stack is often not enough on its own.

### HUD multifamily

We help you easily meet testing and mitigation documentation requirements for HUD multifamily projects. The 2026 HUD MAP Guide radon requirements strictly dictate the testing plan on financed properties. Missing these environmental regulations from HUD, Fannie Mae, or Freddie Mac can completely stall a multimillion-dollar closing.

Our technicians test the exact ground-floor units required by current law and design mitigation systems for elevated buildings. Your lender receives all the organized records they need to finalize your funding. You can review the detailed 

HUD radon requirements for multifamily properties

[/guide/hud-radon-requirements-multifamily/ →](/guide/hud-radon-requirements-multifamily/)

 to see the exact standards.

### Schools

We schedule testing around occupancy and HVAC operation to avoid disrupting class time for schools. The EPA estimates that nearly 1 in 5 US schools has at least one schoolroom with short-term radon levels above 4.0 pCi/L. That means more than 70,000 schoolrooms nationwide are currently exposing students to high radon levels.

Our team focuses on frequently occupied ground-contact rooms to ensure accurate readings. The testing process follows strict protocols to protect everyone on campus:

-   Testing during normal HVAC operation hours
-   Targeting high-risk ground-floor rooms
-   Reporting results clearly to administrators and boards

## Commercial Radon Systems: Problems We Solve

### A large slab that one suction point can’t cover

Our commercial designs tackle big footprints, grade beams, and thickened slabs that easily break up the pressure field under a building. A single residential suction point usually only covers about 1,500 to 2,000 square feet under ideal conditions. Commercial properties simply need a much bigger approach.

We use multiple suction points tied into heavy-duty commercial rooftop exhaust fans to handle the extra square footage. Balancing dampers are then adjusted carefully so every single zone gets enough suction to pull the gas away.

### A lender deadline with no testing plan

Financing can stall entirely when a comprehensive radon testing plan isn’t scheduled early in the process. Commercial testing protocols often require a strict minimum of 48 to 72 hours of closed-building conditions. You cannot simply rush this step at the very last minute.

Our testing coordinators step in to build a realistic timeline that satisfies everyone. The process includes handling all the critical logistical details:

-   Drafting the required testing protocol
-   Scheduling around active tenants
-   Monitoring closed-building conditions
-   Formatting the final lender reports

We deliver the final documentation in the exact format your financial institution expects to keep your closing on track.

### A passive stack that isn’t doing the job

Many new commercial buildings rely solely on passive vent stacks to handle soil gases. The problem is that these passive systems frequently fail to pull enough air to make a difference. When pre-occupancy or later tests come back high, you need an immediate solution.

We fix this by adding a powerful in-line fan that turns the passive system into a highly effective active one. This simple Active Sub-Slab Depressurization (ASD) upgrade can reduce indoor radon concentrations by up to 99%. Your building will easily pass its final occupancy inspections.

### Vapor intrusion concerns

Soil-gas depressurization can also safely address major vapor intrusion mitigation needs on your property. Old industrial sites often leave behind harmful volatile organic compounds like TCE or PCE in the soil. Breathing these chemical vapors creates severe health risks for your building occupants.

We will review all the environmental site data and design a dual-purpose system that handles both concerns at once. This smart approach vents out both radon and chemical vapors safely above the roofline. Your liability drops significantly with one single installation.

## How Is Commercial Radon Work Priced in Iowa?

Commercial projects are always quoted after a highly detailed, project-based estimate. While basic residential mitigation averages around $1,500 in the US, commercial systems can range from $3,000 to over $10,000 depending on the footprint. Your specific price relies heavily on a few key factors:

-   Total square footage of the building slab
-   Number of individual rooms or ground-floor units
-   Current stage of the project (new build vs retrofit)
-   Required documentation formats for lenders

We factor all of these variables into a transparent proposal so there are no surprise fees later. Send us your property plans or a detailed building list to get the process started. Our estimators will scope the work thoroughly and give you a firm project price before anything is scheduled.

Got Questions?

## Commercial and Multifamily Radon FAQs

Do you handle HUD multifamily radon requirements?

Yes. We provide radon testing and mitigation for HUD-financed multifamily properties, along with the documentation lenders require. We plan testing to the applicable ANSI/AARST multifamily protocol, and we recommend confirming current program rules with your lender at the start of the project.

How many units need to be tested in a multifamily building?

Testing protocols like ANSI/AARST MAMF set the sample. In general, ground-contact units are tested, along with a portion of upper-floor units. We'll build a testing plan for your building and explain it before we schedule.

Can you test schools during the school year?

Yes. School radon testing is usually done with the HVAC system running as it normally does when the building is occupied. We schedule placement and pickup around class time and building access.

How are large buildings mitigated?

Large slabs usually need multiple suction points connected to one or more commercial-grade fans, with balancing dampers to even out suction. Some buildings also use HVAC-based approaches. We design to standards like ANSI/AARST RMS-MF for multifamily buildings and RMS-LB for schools and large buildings.

Do you work with builders on multiple homes?

Yes. We give project-based estimates for builders and developers, provide rough-in guidance, activate passive stacks when tests come back high, and run pre-occupancy tests.

What is radon-resistant new construction?

Radon-resistant new construction (RRNC) adds a gravel layer, a sealed membrane and a vent stack before the slab is poured. It costs less to build in than to retrofit. If a test later shows elevated levels, adding a fan makes the passive stack an active system.

Do you handle vapor intrusion?

Yes. Depressurization systems that control radon can also reduce soil-gas vapor intrusion beneath light commercial buildings. We'll review your site data and recommend an approach.

How is commercial radon work priced?

Commercial work is priced per project after a site review. Building size, the number of units or rooms, project stage and documentation needs all affect the scope.
