Why You Need a Plumbing Permit
In Detroit, plumbing work must comply with the Michigan Building Code (MBC), which is locally administered and enforced by the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED). This state code, adopted under Michigan's Stille-DeRossett-Hale Single State Construction Code Act (PA 230 of 1972), is augmented by local ordinances within the City of Detroit Code of Ordinances, Title 4 - Buildings and Building Regulations. The primary legal basis is that any alteration, installation, or repair to plumbing systems (water supply, distribution, drainage) requires a permit to ensure the work meets standards for safety, sanitation, and water conservation, protecting public health and property.
Working without a permit or failing an inspection carries significant risks:
- Stop-Work Orders: BSEED inspectors can issue an immediate stop-work order, halting all construction and potentially delaying your entire project opening by weeks or months.
- Fines and Penalties: Violators are subject to municipal civil infractions with daily fines that accumulate until compliance is achieved. Unpermitted work may also be subject to double permit fees.
- Certificate of Occupancy Denial: The city will not issue a final Certificate of Occupancy (C/O) if any plumbing work is not properly permitted and inspected, meaning you cannot legally open for business.
- Required Demolition: The most costly consequence: the city can require you to demolish non-compliant plumbing work at your own expense so inspectors can verify compliance with the code before re-covering walls or floors.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, BSEED has integrated its permit application tracking more fully into the online Accela Citizen Access portal, although in-person submissions and payments at the Coleman A. Young Municipal Center remain an option for most applications.

Commercial Building Type
checkboxCheck this box only if your restaurant is located in a property zoned for and operating as a commercial business use.
COMMON MISTAKE: Leaving this blank or checking it for a mixed-use residential building without the required separate commercial unit classification, causing a mismatch with Detroit zoning records.

Licensed Contractor Hired
checkboxCheck this box to affirm that you have hired a plumbing contractor currently licensed by the State of Michigan and the City of Detroit to perform the work.
COMMON MISTAKE: Checking this box without a signed contractor agreement, which BSEED can verify through their licensing portal, leading to an immediate application hold.

Top 5 Plumbing Permit Mistakes
1. Submitting Incomplete Plumbing Fixture Counts
Omitting or miscounting fixtures (toilets, sinks, water heaters) triggers immediate rejection for an incomplete scope of work. The Detroit Buildings, Safety Engineering and Environmental Department (BSEED) uses this count to calculate water demand and required venting. Based on ApronPrep's analysis, leaving this blank or estimating incorrectly adds 1-2 weeks for correction and resubmission. To avoid: Create a detailed list from your construction plans, including every fixture that connects to the water supply or drainage system.
2. Using Incorrect Property or PID Number
Entering an address without the official Parcel Identification Number (PID) or using an outdated PID from a prior owner's records causes the application to be unlinked from the city's property file. BSEED's system cross-references the PID with zoning and prior permit history. This mistake typically adds 3-5 business days of administrative delay. To avoid: Verify the current 10-digit PID for your exact lot using the Detroit City Assessor's online database before you apply.
3. Misidentifying the Type of Work (New vs. Repair/Alteration)
Checking 'Alteration/Repair' for what is legally considered 'New' work (like adding a full bathroom where none existed) violates the Detroit Construction Code and can lead to permit revocation, fines, and failed inspections. The fee structure and plan review requirements differ significantly. Based on ApronPrep's analysis, this mistake can cause a rejection that requires a completely new application, adding 2-3 weeks. To avoid: Consult the Detroit Construction Code, Section PC 105.2, or call BSEED's Plumbing Division to confirm your project's classification before filing.

Timeline: Varies
Step 1: Verify if plumbing work requires a permit (new installation, renovation, or repair of kitchen sinks, grease traps, etc.)
Review the Detroit BSEED website or call (313) 224-2733 to confirm your specific job needs a permit. Minor repairs like fixing a leaky faucet typically do not require one, but new installations, renovations, and work on grease interceptors, commercial kitchen sinks, and waste lines almost always do. Making the wrong call here is the most common starting mistake, leading to stop-work orders and fines if unpermitted work is discovered during a future inspection.
Step 2: Ensure plumbing contractor holds valid Michigan State Contractor License and Detroit City Registration
Your contractor must hold a current Michigan plumbing contractor license (verify via LARA's online database) and be registered with the City of Detroit as a Master Plumber. You must provide their license and registration numbers on the permit application. BSEED will reject applications submitted by unregistered contractors, which adds 2–3 weeks for you to find a qualified, registered plumber and restart the process.
Step 3: Gather required documentation including contractor licenses, workers compensation insurance, UIA employer number, and master plumber credentials
Compile a packet with the contractor's State of Michigan License, Detroit Master Plumber Registration, Certificate of Workers' Compensation Insurance (or a signed waiver form), and their Michigan Unemployment Insurance Agency (UIA) employer account number. Missing the Workers' Comp certificate is the #2 cause of rejection. Have digital and physical copies ready for submission.

See All RequirementsProcessing times vary significantly based on project complexity and department review workload. According to the Detroit Buildings, Safety Engineering, and Environmental Department (BSEED), review for simple repairs can take 5-10 business days, while complex new installations can take several weeks. Plan your project timeline accordingly and contact BSEED to confirm current wait times before starting work.
The official government filing fee range for a plumbing permit in Detroit is $0–$0, as per the BSEED fee schedule. However, this base permit fee typically covers plan review only; you may incur separate fees for required inspections and other related approvals, such as a concurrent Building Permit. Not legal advice — verify total project costs with BSEED.
No, plumbing permits are issued for a specific location and scope of work. A permit cannot be transferred to a new address, as the inspection is tied to the installed systems at the original site. For a new location, you must submit a complete new application, as the requirements for a new Certificate of Occupancy may also apply depending on the work.
Plumbing permits are not renewable annual licenses; they are one-time approvals for a specific construction project. The permit expires if the approved work is not started within 180 days or if work is abandoned for 180 days, per BSEED rules. For ongoing operational compliance, you need other recurring licenses, such as an annual Business License (Restaurant).
A BSEED inspector visits your site to verify the installed work matches the approved plans and complies with the Michigan Plumbing Code (PA 230 of 2002). They check for proper materials, venting, supports, trap seals, and connections. Failing an inspection adds delays and re-inspection fees, so ensure all work is complete and accessible before scheduling.
