Grandville mixes established neighborhoods with newer development around the Rivertown corridor, which means the housing runs from mid-century through to construction still going up. The inspection changes considerably depending on which end of that range you are buying at.
In the older sections we concentrate on the systems that have already been replaced once and are approaching a second replacement, and on the quality of that first round of work. A furnace installed twenty years ago into a house built forty years before it is a common arrangement, and whether the ducting and combustion venting were properly adapted at the time is a question worth answering. Original electrical panels, aluminum branch wiring in certain late-1960s and 1970s homes, and galvanized supply lines all belong on the list.
In the newer stock the questions are about how well the house was finished rather than how well it has aged: attic insulation coverage, sealing at penetrations, and whether the grading directs water away from a foundation that has not yet had time to demonstrate a problem.
Grandville sits in Kent County, which the EPA places in Radon Zone 2 with a predicted average indoor level between 2 and 4 pCi/L. A radon test is inexpensive relative to what it tells you.
