Radon Inspection Requirements for Montgomery County, Maryland Landlords
As of recent years, radon inspection has become a mandatory requirement for single family homes, townhomes, and ground floor condominium rental properties in Montgomery County, Maryland. Radon, a naturally occurring radioactive gas, is odorless, tasteless, and invisible, but exposure to it over prolonged periods can increase the risk of lung cancer. In fact, the Environmental Protection Agency (EPA) has identified radon as the second leading cause of lung cancer in the U.S. after smoking.
Understanding Radon and Its Risks
Radon gas is produced from the natural breakdown of uranium in soil, rock, and water, and it can infiltrate buildings through cracks in foundations and walls. This infiltration process is particularly common in basement-level spaces and lower floors of properties, although radon levels can vary widely from one building to another. Since radon has no immediate side effects, people can be exposed without realizing it until years later, making proactive radon testing critical.
Radon Testing Requirements in Montgomery County
Montgomery County’s law for radon testing, known as Bill 31-15, mandates that all rental properties must be tested for radon every three years (every two years for the City of Rockville). The county sets a maximum safe level of radon at 4.0 picocuries per liter (pCi/L), which aligns with the EPA’s recommended action level. If a property tests above this threshold, landlords are required to take action to mitigate radon levels to safe levels before renting the property to tenants.
Steps for Compliance with Radon Testing
Hire a Certified Professional: The law requires that radon testing be conducted by a qualified radon measurement professional.
Conduct Testing and Take Action if Necessary: The radon testing process involves using devices to measure radon levels over a minimum of two days. If the test reveals levels above 4.0 pCi/L, landlords must arrange for radon mitigation by a licensed mitigation specialist to reduce radon to safe levels.
Retain Test Records: Montgomery County requires landlords to keep radon test results and make available to tenants or prospective tenants.
Radon Testing as a Standard Practice
In addition to meeting regulatory requirements, regular radon testing is a proactive way to ensure a property remains safe. Montgomery County’s radon testing regulations reflect growing public health awareness around radon and underscore the importance of safety in rental housing. By staying informed and compliant with these requirements, landlords not only fulfill their obligations but also contribute positively to the community’s overall health.
