Commercial & Multifamily Radon Testing in Pasadena, California

Certified Testing for Historic, Institutional, and Modern Properties in the San Gabriel Valley

Pasadena is a city rich in history and architectural diversity, home to everything from Craftsman-era apartment buildings and historic mixed-use corridors to medical facilities and upscale condos. As this vibrant market continues to evolve, radon testing has become a critical step in environmental safety and loan compliance—especially for properties undergoing refinancing, redevelopment, or HUD-backed financing.

Radon is a naturally occurring radioactive gas that enters buildings through the soil. While you can’t see or smell it, elevated radon levels can build up in enclosed spaces and pose long-term health risks. With Pasadena’s mix of older foundations, basement units, and high-density residential areas,. Our commercial radon testing in Pasadena helps protect both building occupants and your bottom line.

Importance of Radon Testing for Multifamily Buildings in Pasadena

Pasadena’s geology, aging infrastructure, and common use of sub-grade units increase the likelihood of radon accumulation—even in properties that appear well-ventilated. Buildings in historic districts and areas undergoing adaptive reuse are especially important to test, as are newer developments built to energy efficiency standards that can limit airflow.

Testing is ideal for:

Historic multifamily properties and converted homes
Affordable and senior housing projects
Medical staff and student housing near institutions
Mixed-use and commercial buildings with lower-level units
Properties involved in HUD, FHA, or Fannie Mae financing
