Plumbing in Dearborn
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.
What plumbing costs near Dearborn
Our estimates are statewide figures, adjusted for Michigan wages and not for Dearborn in particular. A drain cleaning is estimated at $160 to $375 per job and a water heater replacement at $1,050 to $2,025 installed, permit included. Both are models, not quotes: national published ranges, adjusted by Michigan's plumber wage ratio to the US (1.07). The Michigan mean wage is $37.14 an hour, which is pay, not price. The published permit fees in Dearborn come to about $195 for a water heater swap, against the $100 the statewide estimate assumes, so the replacement estimate here is $1,125 to $2,125. All eleven estimates are on the Michigan page, and each service page shows its own beside the prices Michigan companies publish. How we estimate costs.
Permits for plumbing work in Dearborn
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.

Work that replaces or alters piping, such as a water heater replacement or a sewer repair, generally needs a permit. Only repairs to the working parts of a faucet or valve and clearing stoppages are exempt from a plumbing permit; other plumbing work needs one.
Plumbing jobs in Dearborn
The short answer to each job, as it applies across Michigan. Each links to the full page with the cost evidence, permit rules and what to try first.
- Emergency plumber in DearbornIf water is running and you can shut it off at the main, do that first, then call an emergency plumber. If you smell gas, leave the house and call your gas utility before anyone else.
- Drain cleaning in DearbornOne slow fixture is usually cleared by cabling that single drain, and Michigan does not require a permit for clearing a stoppage. If several drains are slow at once, or the lowest drain in the house backs up, the blockage is further down the line and a camera inspection is the step that shows whether you have a clog or a damaged pipe.
- Water heater repair in DearbornMost water heater repair calls come down to one part: a pilot or thermocouple on a gas heater, an element or thermostat on an electric one, or a relief valve. If the tank itself is leaking, repair is usually off the table and it becomes a replacement.
- Water heater replacementA water heater replacement in Michigan needs a plumbing permit, because the state exempts only faucet and valve repairs and clearing stoppages. For a gas heater, LARA's mechanical FAQ says the installer needs a mechanical license and a plumbing contractor license, with both permits.
- Sewer line repairA sewer line repair starts with a camera inspection, because a clog and a broken pipe look the same from inside the house. In Michigan the permit comes from your city or township, and you have to call MISS DIG 811 before anyone digs.
- Leak repairIf a pipe has frozen or burst, shut off the water at the main valve first, then call a plumber. The State of Michigan says never to use a torch or open flame, and that a hair dryer may thaw a pipe if you start near the faucet.
- Sump pumpSump pump repair in Michigan usually comes down to one question: did the pump fail, or did the power? The State Police say basement flooding more often comes from sump pumps failing in power outages than from sewer water backing up, so a repair visit should look at the backup as much as the pump.
- Toilet and fixturesA plumber for a clogged toilet is clearing a stoppage, which Michigan law treats as minor repair that needs no permit. A swap to a new toilet is different: local rules vary, and some city fee schedules charge per fixture.
- RepipingRepiping near you means replacing the supply pipes inside the house, and in Michigan that is permit work, because the state's only exemptions are faucet and valve parts and clearing stoppages. It is a separate job from replacing a lead service line, which is the pipe from the street main to the house.
- Water softenerBefore you pay for water softener installation in Michigan, find your utility's hardness number. Grand Rapids water averaged 142 mg/L in 2025, Detroit-area GLWA water ran about 96 to 130 mg/L, and Lansing and Ann Arbor soften at the plant, so the answer depends on your address.
- Gas lineGas piping in Michigan sits under the state's mechanical license rules, which list fuel gas piping as a license classification, so confirm the license class on LARA before anyone touches your line. If you smell gas, leave the house and call 911, then DTE at (800) 947-5000 or Consumers Energy at 800-477-5050.
