Foundation work in Portage
In Portage the median home value is $243,400 and 53.8 percent of homes predate 1980, among 49,015 residents. Kalamazoo County is EPA radon Zone 1, with a predicted indoor average above 4 pCi/L, and EGLE says the residential code requires radon-resistant construction in new homes in that county; existing homes need a test. The city issues plumbing permits and its 2024 schedule starts at $50 including one inspection, which we read through a summary, so confirm it; plumbing is the permit that covers a sump or an interior drain.
No Portage page we found says if wall repair or waterproofing needs a building permit, so ask the office first. A homeowner doing the work on their own occupied home is exempt from the state license rule, but a company is not once the job reaches $600. EGLE adds that a mitigation system generally costs $800 to $2,500 in Michigan. Kalamazoo is 5.4 miles away.
