Rochester Hills particulars
Rochester Hills is among the newer large cities in the state: 41.7 percent of homes predate 1980, against 90.1 percent in Detroit, and the median value is $377,400. Newer does not exempt a house from water, since a sump discharge or a failed grade can cause a wet wall at any age. The Building, Ordinance and Facilities department at 1000 Rochester Hills Dr takes calls at 248-656-4615 and inspections at 248-656-4619; its page says a plumbing permit is needed for new fixtures and alterations, and we found no page on foundation work, so ask.
Oakland County is EPA radon Zone 2, and EGLE says about one in four Michigan homes is expected to test above the 4 pCi/L action level, newer or older. The 2015 Michigan Residential Code is still the edition in effect after the July 2025 court order, so ask your contractor which edition the quote assumes. Rochester is 2.6 miles away and Auburn Hills 4.4.
Basement waterproofing in Rochester Hills: what to know
That wording is not confirmed on the city's own page in full, so ask the city. A sump or interior drain may count as alteration, so ask. We found no waterproofing line, unlike Livonia and Warren, which print one.
Oakland County's former lake beds are described by the USGS as clay-rich with low permeability in the southeast; Rochester Hills is in the southeast, though that is our interpretation and not a lot finding. Start with grading and gutters, as University of Minnesota Extension suggests, and see the waterproofing guide. Ask which craft on the state license covers the job; basement waterproofing is a named craft on the maintenance and alteration license, which you can check at michigan.gov/statelicensesearch.
Permits for basement waterproofing in Rochester Hills
Five of the ten cities in this set name waterproofing as a permit item, and the rest print no line, so ask your city.
Many cities run their own building department, so start by asking the City of Rochester Hills building department who issues foundation repair permits.
When a wet basement is an emergency
- Water is rising near the electrical panel, outlets or furnace. Stay out of the water.
- A wall is bowing or has cracked inward while wet.
- Damp patches or a musty smell in dry weather.
- A seep after heavy rain that drains away on its own.
What to check before you call about a wet basement
Try this first: ask which permit applies to a new sump, and who files it.
- Run a humidity check and watch whether the damp shows on dry days; condensation looks like a leak in summer.
- Make sure downspouts end beyond the wall and the soil slopes away from it.
- Ask each company where the water enters and what it would try first.

How we estimate costs: the Estimated range row is a model, not a quote. It takes two published national ranges for this job (cost guides from third-party sites that we have not verified and do not cite) and multiplies them by Michigan's construction laborer median wage ratio to the US (1.05, BLS 2025 data read through O*NET OnLine). No permit fee is added: the city permit rows below are shown as printed. The wage and permit rows are what workers are paid and what a city's own schedule charges, and neither is a price. Your soil, water and the repair method move a real quote well outside any range, so get an independent diagnosis first. We have not collected quotes, and we found no Michigan foundation company that publishes a price we could count. Full method.
Questions about basement waterproofing

One where below-grade walls are treated to resist liquid water, not only dampness. The 2015 residential code calls for dampproofing in ordinary conditions and waterproofing where a high water table or severe soil-water conditions are known to exist.
