Dearborn particulars
A Dearborn plumbing permit starts at $180. The application form dated May 2024 sets a $100 administrative fee plus an $80 minimum permit fee, which covers one rough and one final inspection, and then $15 each for fixtures, a hot water tank or a sump. Mail goes to 16901 Michigan Ave, Suite 7; questions go to 311 or DBNinspections@dearborn.gov, and older forms list different phone numbers. Lead is the other number to know.
The city's 2024 report lists 6,932 known lead service lines and 1,219 of unknown material among 32,733 total, with 1,766 lead lines replaced since 2019. If you own an older house, ask about your own line before you plan any work near the street. The water is Detroit River water from GLWA's Springwells and Southwest plants, and the 2024 tables show average hardness of 101 and 102 mg/L, about 5.9 grains per gallon, with ranges from 88 to 114.
Flooding is the local story. FEMA awarded more than $8.1 million toward storm sewer upgrades and basement backup prevention in east Dearborn after the 2021 flood, and the city's one-pager says roughly two-thirds of homes were hit by basement sewage that year (we read this through a search summary). Dearborn has 107,846 residents, 84.0 percent of homes predate 1980, and the median value is $205,900. Melvindale, Allen Park and Dearborn Heights are the neighbours.
Drain cleaning in Dearborn: what to know
The city's one-pager says roughly two-thirds of homes had basement sewage in 2021 (we read this through a search summary). It advises cleaning house traps, extending downspouts and calling the Sewer Department at 313-943-2042. About 84.0 percent of homes predate 1980. A drain that backs up only in heavy rain points to the sewer rather than a hair clog, so say so on the call.
Thompson Trenchless, in Wyandotte, lists a Drain Opening and Camera Package at $250 as a special, alongside $150 to $300 for basic snaking. That special sits inside the five-company span of $99 to $300 for published drain cleaning prices, read Oct 19, 2026.
Permits for drain cleaning in Dearborn
Clearing a stoppage is one of two things Michigan's plumbing permit rule exempts, along with repairing the working parts of a faucet or valve, as long as the existing piping and fixtures are not altered.
Many cities run their own building department, so start by asking the City of Dearborn building department who issues plumbing permits. The State of Michigan's Statewide Jurisdiction List shows that Wayne County itself does not run a plumbing program, so permits come from the city or township, or from the state where no local agency enforces the code.

Blocked drains that cannot wait
- Sewage is coming up through a floor drain, tub or toilet.
- Every fixture in the house is backing up, not one.
- Water from a backup is spreading toward the electrical panel.
- One slow sink or tub with everything else draining.
- A toilet that clears with a plunger.
What to try before you call
Try this first: ask the plumber whether a camera is part of the price, since a repeat backup is the case that needs one.
- Pull the stopper and clear hair by hand from a bathroom sink or tub.
- Plunge with a cup plunger on a sink or a flange plunger on a toilet, with the overflow blocked.
- Put a bucket under the trap and remove the trap under a sink to check for a plug.
- If two or more fixtures are slow, stop. That points past the fixture and is a job for a cable machine.

Questions about drain cleaning
How do you clean a sink drain?
Start by hand: remove the stopper, clear hair, then plunge or remove the trap under a bucket. Clearing a stoppage like this needs no permit in Michigan. If the water still will not leave, the blockage is past the trap and you want a cable machine.
How much does it cost to clean a main sewer line in Michigan?
A main line clog costs more than a sink drain in the national ranges we read, and our estimate for drain cleaning in general is $160 to $375 per job, a model and not a quote. Ask for the price of the cleaning and the camera together, and ask whether the cleanout is accessible.
Does drain cleaning need a permit in Michigan?
Clearing a stoppage does not, provided no piping or fixtures are altered. That is the state's exemption. Replacing any piping does need a permit, and only a licensed plumber may do that work.
