Muskegon has one of the deepest and oldest housing stocks on the lakeshore, built across a long industrial history, and that gives its houses more character and more accumulated history than most West Michigan markets.
Older industrial-era housing brings a specific set of questions. Knob and tube wiring surviving in walls and attics, often partially replaced in the most awkward possible configuration. Galvanized supply lines that restrict before they leak. Foundations of fieldstone or early block, with the mortar loss and moisture penetration that a century of Michigan winters produces. Roofs carrying multiple layers of shingles, which conceals the condition of the decking beneath and shortens the life of the assembly above. Chimneys serving appliances they were never designed for after a heating system was replaced without the flue being reconsidered.
Muskegon also has a substantial rental sector, and rental maintenance is functional by design rather than thorough. There is a real difference between a system that works on the day of the inspection and a system that has been properly looked after, and saying which is which is the job.
Muskegon County falls in EPA Radon Zone 3, predicted average indoor level below 2 pCi/L, the lowest of the three categories. Older basements with unsealed floors and open sumps remain worth testing regardless of the county prediction.
