Fees, valuation & enforcement
Permit fees are a project input. Enforcement exposure is a project risk. Use the official schedule where available, then confirm valuation, trade permits, plan review, and inspection charges with the Authority Having Jurisdiction.
Official fee pathway
The final charge may depend on declared construction value, occupancy classification, square footage, plan review, state surcharges, trade permits, technology fees, and inspection activity. Do not use a neighboring city’s fee table as a substitute for this jurisdiction.

Ask the counter to confirm current charges before submitting a project with multiple trades or a change of use.
Financial exposure
Plan for building, mechanical, plumbing, electrical, fire, energy, zoning, septic, right-of-way, or other reviews that the project scope triggers. The lowest initial permit fee is not always the lowest project cost.
Enforcement exposure
When work begins without authorization, the agency may halt the site, require corrective plans, impose additional fees, withhold inspection release, or require concealed work to be exposed for review.
Closeout exposure
A missing final inspection or certificate can complicate occupancy, refinancing, sale, insurance, and utility connection. Preserve the approved plans and signed inspection record through closeout.
Professional field note
Even when a cosmetic or minor project does not require a building permit, zoning, floodplain, shoreline, historic, utility, fire, or right-of-way controls may still apply. Confirm the full jurisdictional picture before work starts.

N/A for general building permits; local review varies. Wayne County's construction-permit review requires a complete application, at least three plan sets, applicable checklists, and plan-review payment, with timing dependent on engineering review and project scope.
For county construction permits, the Permit Office reviews plans and inspects work within county road rights-of-way and township subdivisions; contact (734) 858-2774 or the DPS engineering contact at (734) 595-6504. General building, electrical, mechanical, and plumbing inspections must be scheduled with the applicable municipal building department or Michigan LARA through its permit system.
Wayne County does not publish a countywide general building-inspection program. The current Michigan LARA jurisdiction list assigns building, electrical, mechanical, and plumbing enforcement among local cities/townships/villages and the state, with Detroit and other municipalities maintaining their own agencies; verify the address-specific authority before applying. Applicable statewide codes include the 2021 Michigan Building Code, 2015 Michigan Residential Code for one- and two-family dwellings while the proposed 2021 residential update is stayed, 2021 Michigan Mechanical and Plumbing Codes, 2023 National Electrical Code with Michigan amendments, and current Michigan energy and rehabilitation provisions. Wayne County separately administers road, drain, stormwater, and certain soil-erosion construction approvals. N/A for countywide building work; exemptions depend on the local enforcing municipality and applicable Michigan code. Wayne County construction permits are required for work in a county road right-of-way, county drain, county-owned land, or qualifying stormwater project, while ordinary building permits are handled locally or by the state.
Why permit costs vary
Building departments commonly calculate charges from valuation, occupancy, floor area, project type, plan review effort, trade scope, state surcharges, and inspection activity. A remodel that appears small on paper may still trigger structural, energy, fire, or utility review. Ask the permit counter which disciplines apply before you finalize the construction budget.
The same discipline applies to enforcement. Correcting unpermitted work after finishes are installed can require demolition, revised plans, additional inspections, and schedule disruption. Authorization is usually the less expensive project-management decision.
