Two Types of Permits
Detroit issues building permits for structural work and separate trade permits for plumbing, electrical, HVAC, and roofing. Most remodels need both kinds. See the full breakdown of which projects need a permit and which are exempt.

✓ Building permit by project cost (S1 pp.7-8): $271.43 for the first $2,000 + $34.09 per started $1,000 over, so $15,123 = $271.43 + 14 x $34.09 = $748.69. Reroofing is not on the Michigan R105.2 exempt list (R 408.30505); Detroit prices it on the general building curve. Note corrected 2026-09-27: it had shown the $12,000 arithmetic.

Detroit prices the building permit on project cost: $612.33 on a $12,000 job and $1,055.50 at $25,000. Electrical, plumbing and mechanical work take separate permits (a water heater is $117, a 100-200 amp service $183). The figures come from the BSEED fee schedule effective January 1, 2024, modified July 18, 2025. A $25,000 kitchen remodel with its building, electrical and plumbing permits comes to $1,071.62.
How Detroit Calculates Building Permit Fees
The building permit fee is $271.43 for the first $2,000 of project cost, plus $34.09 for each started $1,000 up to $25,000, then $24.53 per $1,000 to $100,000. A $7,100 deck pays $475.97, a $12,000 reroof $612.33 and a $25,000 job $1,055.50.
Trade permits are separate. Plumbing is a $73 application fee plus $44 per fixture, so a water heater is $117. Electrical starts with a $66 base; a 100-200 amp service adds $117 ($183), an EV charging station $176 ($242), a grid-connected solar system $278 per inverter ($344). A split-system air conditioner is $130; a furnace $203.
For a kitchen or bath remodel the trade permits depend on circuit and fixture counts, a $59 concealed-wiring rough inspection, and, when plans are required, electrical, mechanical and plumbing plan review at 7% of the building permit fee each. Our reference kitchen, with its fixtures replaced in place and one new lighting circuit, comes to $1,071.62 at $25,000, and our reference bath to $830.65 at $15,000; neither needs plan review.
Chuck's Take
"Chuck here. I bid jobs all over Missouri but the math works the same. Detroit's separate trade permits mean your guy better not lowball the permit line. If the bid shows one permit number for a kitchen, ask which permits it covers."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
What Needs a Permit in Detroit?
Detroit enforces Michigan's single state construction code. Its residential exempt list (Mich. Admin. Code R 408.30505, amending R105.2) covers one-story detached accessory structures up to 200 square feet, fences up to 7 feet, retaining walls up to 4 feet, sidewalks and driveways up to 30 inches above grade, painting, papering, tiling, carpeting, cabinets and counter tops, and small detached decks and patios within stated limits. Historic-district work such as fences takes a $106 special permit.
Reroofs, windows, siding, attached decks, remodels, water heaters and electrical work need permits.
What Happens If You Skip the Permit in Detroit?
The BSEED schedule lists "Fail to Obtain Permit" at $176, and again $176 at court referral and $176 at the court date, on top of the permit itself. A "Fail to Gain Access/ not ready" inspection is also $176.
Unpermitted work also surfaces at sale and in insurance claims. Pull the permit before work starts.
How Long Is a Building Permit Good For in Detroit?
The fee schedule lists a Permit Extension at $227. It does not state the permit's validity period; confirm it with BSEED when the permit is issued.
Refunds must be requested within one year of issuance, and 35% of the building permit fee is deducted to cover zoning, structural and building plan review and processing.
Who Should Pull the Permit in Detroit?
Your contractor pulls the permit in Detroit. Not you. They take legal responsibility for the work. I never recommend homeowners pull their own permits here even though state law allows owner-builders on primary residences. The paperwork gets messy with separate trade permits. Contractors know the BSEED system. They know which inspectors want what. Read your contract. Make sure it says the contractor pulls every required permit. If they ask you to pull it that's a red flag. Walk away. The guy who won't stand behind the permit won't stand behind the job.
Chuck's Take
"Never let the homeowner pull the permit. I won't work that way. Too many inspectors know my name and my work. When I pull it I own the mistakes. When you pull it I still fix the mistakes but now we both lose time and money. Get it in the contract."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
Why Detroit's Separate Trade Permits Matter
Detroit keeps every trade on its own permit: building, electrical, mechanical and plumbing. Each has its own schedule in the BSEED fee book, and a remodel draws several of them.
That makes the building permit alone a poor guide to the total. Ask your contractor to list each permit in the bid.
