Professional radon measurement
Multifamily & Commercial Radon Measurement in Maryland
Project-specific radon testing for property owners and management teams, plus environmental, engineering, consulting, and other project teams that need a qualified local measurement provider or field/project partner.
The right approach starts with the objective, the property, the controlling requirements, building information, and the circumstances of the project—not a universal device count or sampling percentage.
Owners & property managers
Discuss the property, objective, access, timing, and reporting needs before establishing the project approach.
Consulting & engineering teams
Coordinate with a qualified local measurement provider or field/project partner when radon is part of a larger project.
Project-specific planning
Keep scope, field execution, quality review, completeness, documentation, and reporting closely connected.
Start with the objective
Before choosing a measurement approach, Smart Home Inspects needs to understand why the project is being tested and what requirement, standard, program, contract, due-diligence objective, or other project need controls the work.
Possible objectives include regulatory or property-management requirements, financing or program requirements, due diligence, occupant or owner concerns, portfolio assessment, or work that is part of a larger environmental or consulting project. The specific requirement still needs to be confirmed for the property and project.
A practical first conversation
What we need to scope a project
You do not need to know every answer before contacting us. “Not sure yet” is a legitimate starting point when the applicable project requirements still need to be identified.
Two ways to work together
The initial discussion can be direct with an owner or manager, or collaborative with a team coordinating a larger environmental or property project.
Owners & property-management teams
We can work directly with owners and property managers to understand the buildings, objective, applicable requirements, access circumstances, timeline, and reporting needs before establishing the project approach.
Consulting, engineering & project teams
We can collaborate as a qualified local measurement provider or field/project partner when radon measurement is one part of a larger project. Scope, responsibilities, access, documentation, and project fit are discussed before work begins.
A project workflow that stays connected
Review the objective
Clarify why testing is needed and what requirement or project need controls the work.
Review property information
Understand the buildings, occupancy, access conditions, and available plans or specifications.
Develop the measurement plan
Set the project approach around the property, objective, applicable requirements, and conditions.
Coordinate access and preparation
Plan communication, entry, device protection, normal building operation, and timing.
Deploy and retrieve devices
Complete field work and document the conditions relevant to the defined measurement scope.
Review and report
Process results as applicable, complete QA/QC and completeness review, and provide project documentation.
This sequence is a planning framework, not a rigid identical protocol for every building. Measurement conditions, quality review, completeness, and the defined project scope remain part of the decision at each stage.
Standards-sensitive planning
Multifamily and commercial measurement may be governed by different standards, requirements, or project specifications depending on the building and purpose of testing. Determining the appropriate measurement approach is part of professional project planning.
There is no universal sampling percentage, device count, or layout that applies to every multifamily or commercial project.
Occupied buildings and tight timelines
Occupied projects may require advance coordination involving occupant communication, unit and building access, HVAC or building operation, device protection, project preparation, and unusual conditions that could affect measurement validity.
Tight timelines do not require shortcuts. Project deadlines are evaluated alongside applicable requirements, measurement conditions, QA/QC, and completeness.
Reporting and documentation
Depending on the defined project scope, documentation may include measurement results, location identification, device information, relevant placement or context photographs, QA/QC documentation, project observations, limitations, and a project summary or report appropriate to the work.
Deliverables are discussed before work begins so the reporting and documentation are appropriate to the defined project scope.
Technical leadership
Direct access to the technical lead
Daisy Rezende serves as the technical lead for multifamily and commercial radon measurement projects. She is an NRPP Radon Measurement Professional, holds a Multi-Family Measurement Certificate (MFM), and is an NRPP Soil Gas Mitigation Compliance Inspector. Her direct involvement keeps project planning, field execution, quality review, and reporting closely connected from scope through completion.

Montgomery County multifamily projects
Some multifamily projects originate from Montgomery County rental radon requirements. Smart Home Inspects can review the property, testing objective, access needs, and applicable requirements to help establish the appropriate measurement approach.
Review Montgomery County rental requirementsMaryland project fit
Smart Home Inspects serves Maryland, with core service areas in Montgomery, Prince George's, Howard, and Frederick Counties. Larger projects outside our core service area are evaluated based on project scope and location.

Multifamily & commercial radon questions
Clear answers for planning a project without turning project-specific requirements into universal rules.
How is a multifamily radon measurement project scoped?
The scope starts with the reason for testing, the property and building configuration, the applicable requirement or project specification, access conditions, and the documentation needed. There is no responsible universal plan for every multifamily or commercial building.
Is there one required sampling percentage for every multifamily property?
No single percentage or device-count formula should be applied to every project. The appropriate approach depends on the controlling requirement, the property, the building conditions, and the purpose of the measurement.
Can Smart Home Inspects work with environmental or engineering consulting firms?
Yes. Smart Home Inspects can discuss working as a qualified local measurement provider or field/project partner when radon measurement is part of a larger environmental, engineering, consulting, or due-diligence project. Scope and project fit are discussed before work begins.
What information should a property manager provide before requesting testing?
Share what you know about the objective, property location, buildings, approximate units or measurement locations, occupancy and access, timing, and reporting needs. If the requirements are not clear yet, that is still a valid reason to start a technical discussion.
How are occupied units coordinated?
Occupied projects may require advance planning for occupant communication, unit and building access, HVAC or building operation, device protection, preparation, and unusual conditions. Project-specific instructions may supersede general residential preparation guidance.
Can you accommodate a tight project timeline?
Timing is part of the initial project discussion. We evaluate the project scope, location, access requirements, measurement conditions, QA/QC, and reporting needs to determine what timeline can be supported without compromising the measurement process.
What documentation may be included?
Depending on the defined scope, documentation may include measurement results, location or device information, relevant photographs, QA/QC records, project observations, limitations, and a project summary or report. Specific deliverables are established based on the project scope and reporting requirements.
Discuss a Multifamily or Commercial Radon Project
Tell us what you know about the property, the objective, and the project timing. If the requirements are not clear yet, start there—we can discuss what needs to be established before planning the measurement.
