Property Management Services
Radon testing for rental portfolios, handled from scheduling to report.
One local laboratory for your Montgomery County rental and sales radon requirements, from a single townhome to a full apartment community.
Experience at portfolio scale
Keep every covered unit tested, documented and ready to lease.
Envirolabs works with many of the area's leading property management companies and with governmental housing agencies. We plan the testing around your buildings and your leasing calendar, so results are on file before you need them.
- One point of contact for your whole portfolio
- Testing scheduled building by building, Monday through Saturday
- A separate written report for each unit, ready to hand to the tenant
Montgomery County requirements
Two local rules affect the properties you manage.
Montgomery County has separate radon rules for rental housing and for home sales. We test for both and give you the paperwork each one calls for.
01 / RENTAL HOUSING
Before leasing
- Applies to ground-contact and basement units in covered single-family and multifamily rentals.
- Test results must be dated within three years before the lease date.
- At signing, tenants receive the results and radon education material.
- Confirmed results of 4.0 pCi/L or higher require follow-up and mitigation steps.
County Code §29-35E · Bill 26-22 · in effect since July 1, 2023
02 / HOME SALES
Before settlement
- Applies to single-family homes and townhomes in the County.
- A radon test must be performed less than one year before settlement.
- The seller must test, or permit the buyer to test.
- Both seller and buyer must receive the results.
County Code §40-13C

Who we work with
From a few rental homes to large housing developments.
Property management companies
Ongoing testing across mixed portfolios, on one account.
Apartment communities
Garden-style and mid-rise buildings with ground-contact units.
Government and housing agencies
Public and assisted housing, with the documentation agencies need.
Townhome and condo associations
Coordinated testing days for many owners at once.
Developers and builders
Testing for new and large housing developments before occupancy.
Individual landlords
Single-family rentals and basement apartments.
Corporate rates
Special rates for portfolios and large developments.
Pricing for multiple units depends on how many there are, where they are and how access is arranged. Tell us about the project and we will send a written quote.
Common questions
What property managers ask us.
Which of my units need a radon test?
The County rental rule covers ground-contact and basement units. Send us your unit list and we will help you identify which ones those are.
How long does a test result stay valid for leasing?
For rentals, the result must be dated within three years before the lease date.
What happens if a unit tests at 4.0 pCi/L or higher?
We explain the result and the follow-up testing and mitigation steps the County requires.
Can you test many units at the same time?
Yes. We schedule by building so that devices are placed and collected in as few visits as possible.
Do tenants have to be home?
No. We arrange access with your office or on-site staff, and leave each tenant a notice explaining the closed building conditions for the test.
