Farmington Hills particulars
At a median value of $333,200, Farmington Hills homes carry enough equity that a bad repair can cost more than a good diagnosis, and 53.7 percent of them predate 1980. The city has 83,316 residents. Oakland County is EPA radon Zone 2, a 2 to 4 pCi/L county average, so a kit from the hardware store is the sensible first step. The Building Division sits at 31555 W. Eleven Mile Rd, 248-871-2450, and takes inspection requests by an online form; confirm which counter handles foundation work, because we found no page that says.
Michigan's contractor license applies from $600 of labor and materials, so a crack injection or a drain job almost always needs a licensed company, and the contract should show its license number. The 2015 Michigan Residential Code is the edition in effect, according to LARA's notice of the July 2025 court order. Farmington is 1.7 miles away and Novi 5.7.
Foundation repair in Farmington Hills: what to know
The Building Division at 31555 W. Eleven Mile Rd, reachable at 248-871-2450, takes inspection requests through a digital form; we could not confirm that on the city's own page, so ask the department. Radon Zone 2 applies to Oakland County, where the city sits. Of the city's homes, 53.7 percent predate 1980. Livonia, Southfield and Novi are the closest neighbors, within about six miles.
At that home value a repair is a big decision, which is why a written engineer's report from someone who does not sell piers is worth asking for. The base 2015 residential code requires a permit to repair a structure, and the city decides how that applies. A state license applies once the work reaches $600.
Permits for foundation repair in Farmington Hills
The base code requires a permit to repair or alter a structure, Michigan's exemption list does not name foundation work, and your city's building official makes the call.
Many cities run their own building department, so start by asking the City of Farmington Hills building department who issues foundation repair permits.
When a foundation problem is an emergency
- A wall is visibly moving or has shifted since you last looked.
- A floor is dropping or a doorframe has pulled apart in days.
- Water is coming through a wall near the electrical panel. Do not step into that water.
- A crack that has not changed in months and lets no water in.
What to do before you call a foundation company
Try this first: ask the Building Division what permit a repair of an existing foundation needs.
- Photograph each crack with a coin beside it, and mark both ends with a pencil and the date.
- Check that downspouts end away from the wall; the University of Minnesota Extension lists grading and gutters ahead of any drainage system.
- Ask the first company who diagnosed the problem and whether it would also do the repair.
What foundation repair costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Farmington Hills in particular. The same table is on the foundation repair page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $2,300 to $8,375 per project | Built from 2 national published ranges, adjusted by the Michigan cement mason median wage ratio (1.05). No Michigan foundation company price is shown, because none of the companies we looked at published a price we could count. |
| Cement masons and concrete finishers, Michigan median | $59,860 a year | What workers are paid (BLS 2025 data via O*NET), not what you are charged. |
| Construction laborers, Michigan median | $49,590 a year | What workers are paid (BLS 2025 data via O*NET), not what you are charged. |
| Civil engineers, Michigan median | $92,100 a year | What civil engineers are paid, not what an engineer's report costs. No wage category covers foundation crews exactly. |
| Building permit, Ann Arbor | $15 application fee, then $100 plus $10 per $1,000 of project cost | Revised July 2025. Basement waterproofing is named. |
| Building permit, Grand Rapids | $79 for work valued at $1 to $1,000; $215 at $20,001 to $21,000 | FY2027 chart. No foundation line. |
| Building permit, Lansing | $175 for work valued at $4,001 to $10,000 | Schedule of July 1, 2026. |
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 cement mason 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 foundation repair
How do they fix foundation problems?
The repair depends on the cause, and the cause has to be found first. Typical work is sealing or injecting a crack, bracing or rebuilding a wall, adding support under a footing, or fixing grading and drainage. We have no source that ranks these methods, so ask why the proposed one fits the cause.
How much does foundation repair cost in Michigan?
Our estimate for foundation repair in Michigan is $2,300 to $8,375 per project, built from national published ranges and adjusted for Michigan wages, because we have collected no Michigan quotes. A crack seal and a pier job sit at very different points in that range. Ask for an itemized price that names the method and the permit, and shows the license number.
Does foundation repair need a permit in Michigan?
Probably, but your city decides. The base code requires a permit to repair or alter a structure and Michigan's exemption list does not name foundation work, yet no state page we read says so in plain words. Ann Arbor, Dearborn, Livonia, Sterling Heights and Warren print waterproofing as a permit item, so call your building office before work starts.
