Yes. Installing a radon mitigation system on a single-family home requires architectural approval because the work may modify both the interior and exterior of the home.
Before installation
- Submit an architectural request for the proposed radon mitigation system.
- Wait for approval before beginning the project.
Exterior piping
If the system includes piping that runs along the exterior of the home, the pipe must be painted to match the color of the home's exterior body.
Important: Do not begin the installation until the required architectural approval has been received.
