Plumbing Permit in Detroit, Michigan
It depends
Sometimes, depending on the project
Before altering plumbing systems beyond the working parts of a faucet or valve, including new or replacement piping, fixtures, drains and water service.
By Mario Bailey, verified against official sources
Quick answer
BSEED requires a plumbing permit for alterations to plumbing systems that involve more than the working parts of a faucet or valve or the clearance of stoppages, and the contractor column of the same guide states the requirement as alterations to plumbing systems including piping. The two exemptions BSEED publishes are the stopping of leaks in drains, water, soil, waste or vent pipe, and the clearing of stoppages or repairing of leaks in pipes, valves or fixtures including the removal and reinstallation of water closets where the repair does not require replacing or rearranging valves, pipes or fixtures. If a concealed trap or pipe has to be removed and replaced with new material, BSEED treats it as new work needing a permit and inspection. Work must be performed by a City of Detroit licensed Plumbing Contractor.
Typical threshold: plumbing alterations beyond the working parts of a faucet or valve or clearance of stoppages.

How to apply in Detroit
You apply for a residential plumbing permit at your local building department by filing an application that describes the scope of work and site, along with construction documents, before any regulated plumbing installation, alteration, or repair begins. Minor repairs that do not touch piping or fixtures are generally exempt, and once issued the permit only stays valid if work is started within its time limit.
What most plumbing permit applications include:
- A permit is required before any owner or authorized agent constructs, alters, repairs, removes, converts, or replaces a plumbing system regulated by the code (IRC R105.1).
- The application must identify and describe the work, describe the site, state the intended use and occupancy, and be signed by the applicant or an authorized agent (IRC R105.3).
- Two or more sets of construction documents must accompany the application, drawn with enough clarity to show the location, nature, and extent of the proposed plumbing work and how it will conform to code (IRC R106.1, R106.1.1).
- Minor plumbing repairs, such as clearing a stoppage or removing and resetting a water closet without rearranging pipes or fixtures, are exempt from permit (IRC R105.2).
- Once issued, a permit is only valid for a limited window, commonly 180 days, and becomes invalid if the work is not started or is abandoned within that time, though extensions can be requested (IRC R105.3.2, R105.5).

Inspections and closing out your permit
Plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.
- Piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
- Rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
- Rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
- The water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
- The framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
- At the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).
- Final inspection is made after all work required by the permit is complete, and includes confirming backflow protection, such as vacuum breakers on hose bibbs, is installed (IRC R109.1.6, P2902.4.3).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Detroit permit portal or by phone at (313) 224-2372.

- Where do you apply for a plumbing permit in Detroit?
- You can apply through the Detroit permit portal or contact the City of Detroit Buildings, Safety Engineering and Environmental Department (BSEED) directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Detroit?
- Under Michigan law (MCL 339.2403(b), (c); MCL 339.2401(a)(iii), (b)(ii)(A); MCL 339.5737(3)(g); MCL 339.6107(2)(d); MCL 339.5819): Yes. A Michigan homeowner may pull the building permit and do the work on their own home without a residential builder license, because the licensing article both defines the trade to exclude them and exempts them outright. MCL 339.2401(a)(iii) says a residential builder is a person that erects a residential structure except for the person's own use and occupancy on the person's property, and MCL 339.2403(b) exempts an owner of property with reference to a structure on the property for the owner's own use and occupancy. Own use and occupancy is the condition, so the exemption does not cover building to sell, and MCL 339.2403(c) limits owners of rental property to maintenance and alteration of that property. The statute sets no cap on how many times a homeowner may use the exemption; the only frequency rule in the article catches purchase, substantial rehabilitation, and resale of the same structure more than twice in 1 calendar year, and MCL 339.2401(b)(ii)(A) exempts work for the person's own use and occupancy from even that. Homeowners can also pull their own trade permits: electrical work in a single family home and accompanying outbuildings owned and occupied or to be occupied by the person doing the work (MCL 339.5737(3)(g)), their own plumbing, building sewer, or private sewer in their single-family dwelling if a permit is secured (MCL 339.6107(2)(d)), and a heating or refrigerating system if the owner affirms in the permit application that they are or will become the owner and occupant (MCL 339.5819). Confirm how Detroit applies this before you apply.
