An Exterior Alteration Application must be submitted for all exterior radon units. While the RHAC would never question the necessity of the unit, certain architectural requirements must be adhered to. The unit will most likely be approved if the exhaust pipe is either located alongside a downspout and painted the color of the downspout, or placed vertically on the side of the house and painted to match the siding. The RHAC may require that the unit be screened (see guideline on Screening).

Application Requirements:

Submit a site (plat) plan including the exact location of the radon unit and a manufacturer's drawing and/or photograph if available and a description of the type of screening (if applicable).
