Mayor and Council Adopt Energy Disclosure and Radon Laws

The Mayor and Council adopted an ordinance on July 18 that applies Montgomery County’s home energy disclosure and radon testing laws to the sale of single-family homes and townhomes in Rockville. The change provides home buyers with access to important home health and energy information. It is proposed to take effect on Sunday, Jan. 1.

The goal is to protect public health from radon exposure and promote home energy efficiency, an objective of the city’s Climate Action Plan.

The new law takes effect on Jan. 1 to allow residents and businesses time to comply with the requirement and to coincide with National Radon Action Month.

Radon, which was Rockville’s focus for Building Safety Month in May, is an invisible, odorless, tasteless, radioactive gas. While no immediate symptoms will signal its presence, exposure at high levels can cause cancer. Testing is the only way to know a home’s radon levels.

The city’s building code requires all new single-family construction to include passive radon mitigation, such as subfloor preparation, installation of a soil-gas retarder, the closure of potential radon entry routes and the installation of vent pipes.
