Always request a radon test as part of the inspection process.
New homes must be built with Radon-Resistant New Construction (RRNC) in:
- The City of Longmont
- The Town of Superior
- Unincorporated Boulder County
Testing After Occupancy
While a home may be built with Radon-Resistant New Construction, most new homes are built with passive techniques (no fan). This means that the home still needs to be tested after move-in. If testing shows a level of 4.0pCi/L or more, a fan can be installed to the existing piping to reduce the level.
