Dearborn particulars
Dearborn's Residential Solar Checklist, updated January 23, 2025, requires both a building permit and an electrical permit. The electrical application has no PV line, so the checklist is where the fees are printed. Building administrative and plan review fees are "$100 administrative fee + $5 per $1,000 of construction cost with a maximum of $250," and the permit itself is "$100 + $15 for each additional $1,000 of construction value over $2,000." The electrical side reads "$100 + at least $80 depending on scope of work." Turnaround is 10 business days.
There's paperwork for the contractor, too. The electrical contractor needs a State of Michigan electrical license and must be registered with the city, and the building contractor needs a residential builder or maintenance and alteration license. Dearborn sits in DTE Electric territory on the MPSC map (confirm your address with DTE), and the checklist says DTE application fees range from $50 to $500, though most residential projects cost $50. The building and trade permits desk answers at 311 or 313-943-2150, per the city's page. If an installer suggests you pull the permits yourself, the checklist's own words are that the city "strongly discourages homeowners from applying directly."
Interconnection and permits in Dearborn: what to know
That application prints an administrative fee of $100 and a minimum permit fee of $80, and the building side's formulas are in the checklist. Both permits are required, with 10 business days for turnaround.
For questions, Building & Trade permits takes calls at 311 or 313-943-2150 (per the city's page), and DTE Electric, Dearborn's utility on the state's map, can confirm it serves your address before its $50 Level 1 or 2 application goes in.
Permits for interconnection and permits in Dearborn
The state electrical permit application asks for the contractor's Michigan license number, so the permit is pulled under it.
When to call 911 and when it can wait
- Smoke, a burning smell or fire at the inverter, panels or wiring is a 911 call. Leave the equipment alone.
- An application the utility hasn't answered yet.
- A permit sheet you haven't been able to find.
What to settle before the paperwork starts
Try this first: call the permits desk and ask for the current checklist before you accept a permit line on a quote.
- Ask who files the utility application and who pulls the city permit.
- Ask your building department for its current solar sheet and whether a building permit is also needed.
- Ask the company which of these fees its price includes.
- Look up its electrical contractor license number with LARA.
- Ask for the utility's approval to operate in writing before the final payment.

These rows are fees that utilities and cities publish, each with the date or fiscal year of the schedule. None is an installer's price, and the estimate model has no row for this service. Full method.
Questions about interconnection and permits
How long does DTE take to approve a solar system?
DTE says the process takes approximately six weeks. It has 10 business days to say whether an application is complete, and you have 60 business days to fix deficiencies.
How much does a solar permit cost in Michigan?
There's no statewide figure, because each city sets its own fee. The cities we cite run from $0 in Ann Arbor, on a 2020 sheet, to $278 per inverter connection per visit in Detroit.
Does Michigan require a building permit for solar too?
Many cities do, including Dearborn, Kalamazoo and East Lansing. Ask your building department what it needs.
