Ann Arbor particulars
Ann Arbor's median home value is $435,100. The city's Building & Construction Services, at City Hall, 301 E. Huron St, takes permits through STREAM and answers at 734-794-6263. The Statewide Jurisdiction List names the city itself as the enforcer. Ann Arbor's published permit pages are silent on garage doors, so the office is the source for whether a swap needs a permit. In Ann Arbor, 64.3 percent of homes were built before 1980.
Whatever door hangs in an older garage, test the opener: the federal standard says a downward-moving door must start to reverse within 2 seconds of contact with an obstruction. If it grinds on, stop using the opener and call. Water under the door is the other thing to check. DASMA's technical sheet says rainwater commonly runs under the bottom of exterior-facing sectional doors, and that the fixes are a slightly sloped sill or a notch in the slab with a floor seal. When a contractor finishes, MCL 570.1110 lets you ask for a sworn statement listing subcontractors, suppliers and unpaid laborers. Ypsilanti is 6.0 miles away.
Opener repair in Ann Arbor: what to know
DASMA says a door that is heavy or needs two hands is probably out of balance, and that the answer is not a more powerful opener. Ask the company to check balance before it sells you a bigger motor. The monthly reversal test is the federal check: the door must reverse on contact with a 1 1/2 inch object or a 2 by 4 laid flat.
On wiring, the federal instructions say to contact a licensed electrician to install a suitable receptacle if there is none. Part 8 of the state rules appears to exempt a cord-and-plug opener on an existing receptacle from an electrical permit, while new circuits do not fit that wording. Ann Arbor enforces its own code, so Building & Construction Services is the office that decides whether a replacement opener in your garage needs anything beyond that.
Permits for opener repair in Ann Arbor
The Part 8 electrical rule says no electrical permit is required to install or replace equipment approved for connection to a suitable permanently installed receptacle.
Many cities run their own building department, so start by asking the City of Ann Arbor building department who issues garage door permits.
Opener problems that cannot wait
- The door does not reverse on the test object or on contact.
- A person or vehicle is trapped, or the door closes on something.
- The door is stuck open and the property cannot be secured.
- The door is heavy, drops or will not hold itself up.
- A remote or keypad that has stopped working while the wall button works.
- A worn light bulb or a noisy opener with the door working normally.
What to check before you call
Try this first: find the opener's label and write down its manufacture date before you call.
- Check that the opener is plugged in and the outlet is live.
- Replace the remote battery and try the wall button.
- Clear the path of the photo eyes, wipe both lenses and check that each shows a steady light.
- Run the reversal test with a 2 by 4 laid flat, and stop using the opener if it fails.
- Note the opener's make and the date on its label.
What opener repair costs
The estimate below is the Michigan-wide one, adjusted for Michigan wages and not for Ann Arbor in particular. The same table is on the opener repair page. How we estimate costs. Prices as of Oct 19, 2026.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $105 to $270 per job | Built from two national published ranges, adjusted by the Michigan garage door technician median wage ratio (0.94). Too few Michigan garage door companies publish a price to show a range, so none is shown. |
| Michigan median hourly wage, mechanical door repairers | $25.18 an hour | Nearest BLS code (49-9011, mechanical door repairers), read through O*NET OnLine. Pay, not price. |
| Michigan 25th to 75th percentile hourly wage | $21.73 to $33.03 an hour | Pay, not price. |
| Michigan median annual wage | $52,370 a year | Pay, not price. |
| Detroit-Warren-Dearborn median hourly wage | $24.12 an hour | Pay, not price. |
| Grand Rapids-Wyoming-Kentwood median hourly wage | $28.65 an hour | Pay, not price. |

| United States median hourly wage, same occupation | $26.79 an hour | Same occupation, national, comparison only. Pay, not price. |
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 garage door technician median wage ratio to the US (0.94, BLS May 2025 data read through O*NET OnLine, using mechanical door repairers as the nearest occupation). The wage rows in the table are what that occupation is paid, which is not a price. Where a Michigan company publishes a price, it only keeps the low end of the range from sitting above it. We have not collected quotes, and only two Michigan garage door companies published a regular dollar price we could count, so no range of Michigan prices is shown. A real quote can land outside the range. Full method.
Questions about opener repair
What do you do when your garage door opener stops working?
Check the power, the remote battery and the photo eyes first. If the opener runs but the door does not move, or you heard a bang earlier, stop and call a company, because a broken spring can cause both. The federal rule says to have a qualified service person repair springs and cables.
How do I test the auto-reverse on my garage door opener?
Lay a 2 by 4 flat on the floor, or use a 1 1/2 inch object, and close the door: it must reverse on contact. The federal rule says to test monthly and after any adjustment. If it fails, stop using the opener.
Do all garage door openers have to reverse?
Openers made on or after January 1, 1993 for sale in the United States must meet the federal standard, which includes reversal on contact within 2 seconds. An opener made earlier is outside that federal standard, so check the date on the label.
