A residential plumbing permit in Michigan costs $55 to $200 in most cities. Fees are set by each local building department, not the state. In Macomb County: Warren charges a minimum of $80 per permit, Sterling Heights charges a $55 application fee plus per-fixture fees ($25–$75 for most items), and Macomb Township starts at $100, priced by the value of the work. Every number below comes from each city's own published fee schedule — sources at the bottom.
Who sets plumbing permit prices in Michigan?
Michigan's construction rules come from the Stille-DeRossett-Hale Single State Construction Code Act (Act 230 of 1972), but permit fees are set city by city. That is why a water heater permit costs $40 in fixture fees in Sterling Heights but $80 in Warren — two cities that share a border. There is no single statewide plumbing permit price.
Two rules apply almost everywhere in Metro Detroit:
- Licensed plumbers pull the permit for work at your home — the cost is usually built into your quote. Ask your plumber to itemize it.
- Homeowners can pull their own permit only for a house they own and live in (owner-occupied), by signing a homeowner affidavit. Warren and Sterling Heights both print this affidavit directly on their permit applications. Rental properties require a licensed contractor.

What about other Macomb County cities?
Clinton Township, Shelby Township, St. Clair Shores, and Roseville each publish their own schedules through their building departments — expect the same $55–$150 range for common residential work. We only print numbers we have verified against an official document, so for those cities check the fee schedule on the city or township website, or call the building department, before budgeting.
What plumbing work needs a permit in Michigan?
In most Metro Detroit cities you need a plumbing permit for:
- Water heater replacement — yes, even like-for-like (see our Michigan water heater permit guide)
- Sewer repair or replacement
- Sump pump and backwater valve installation
- Moving or adding drain or supply lines
- Backflow preventers
You generally do not need one for stopping a leak in an emergency, clearing a clog, or swapping a faucet washer — but replacing fixtures often carries a small fee when it is part of permitted work.
Why pulling the permit is worth it
- Unpermitted work surfaces at sale time. Home inspectors and city certification inspections (Warren charges $300 for a residential certification inspection) flag missing permits, and you pay penalties on top — Macomb Township adds $150 for work started without a permit.
- Insurance. If an unpermitted water heater or sewer line fails and floods your basement, a missing permit gives the carrier an argument to cut your claim.
- The inspection is the product. For $80–$137 you get a city inspector checking that gas lines, venting, and backflow protection are right. That is cheap insurance on a $1,500+ job.
Frequently Asked Questions
How much does a plumbing permit cost in Michigan?
Most residential plumbing permits in Michigan cost $55 to $200, set by your city's building department. In Macomb County, Warren charges an $80 minimum, Sterling Heights charges $55 plus per-fixture fees (a water heater totals $95), and Macomb Township starts at $100 based on the value of the work.
Can I pull my own plumbing permit in Michigan?
Yes, if you own and occupy the home. You sign a homeowner affidavit on the permit application taking responsibility for code-compliant work and inspections. Warren and Sterling Heights both include this affidavit on their forms. Rental properties and flips require a licensed plumbing contractor to pull the permit.
How much is a water heater permit in Michigan?
It depends on the city: $80 in Warren, $95 total in Sterling Heights ($55 application fee plus $40 fixture fee), and roughly $108–$118 in Macomb Township for a typical $1,800 replacement priced by construction value. A permit is required even for a like-for-like water heater swap.
Does my plumber's quote include the permit fee?
Usually, but not always — ask for the permit as a line item on the quote. A legitimate licensed contractor will never suggest skipping the permit on a water heater, sewer, or gas-connected job, because the contractor's name is on the permit record.
What happens if I do plumbing work without a permit in Michigan?
You risk penalty fees ($150 in Macomb Township), forced re-inspection or re-work, problems when you sell the house, and potential insurance-claim disputes if the unpermitted work fails and causes damage. The permit is the cheapest part of any plumbing job.
How long does a plumbing permit take in Macomb County?
Simple residential plumbing permits in Warren, Sterling Heights, and Macomb Township are often issued the same day to a few business days when applied for online. The inspection is scheduled after the work is complete, and first re-inspections of corrected violations are free in Macomb Township.
