Livonia particulars
Livonia's electrical permit application charges $8 for each solar panel, item 30 on the form. The line itself says solar "Needs Plan Review and Building Permit." That's as of the April 3, 2025 copy of the form. Your panel count drives the electrical amount. The application doesn't print a price for the building permit and plan review, so ask the Inspection Department (734-466-2580, per the city's page) what those cost for a rooftop array.
Livonia falls in DTE Electric's territory on the MPSC map, and no other utility polygon intersects the city. Ask DTE to confirm your address. If you're thinking of doing the wiring yourself, Michigan's licensing law exempts a homeowner working on a single-family home they own and occupy. That exemption covers the license only. The city permit, its inspection and DTE's interconnection still apply, and Livonia's form still asks for the building permit with plan review.
Whoever does the work, the plan's panel count times $8 is the electrical figure Livonia's form produces, and it's the number to look for on the quote.
Interconnection and permits in Livonia: what to know
The application labels it 'Solar Panel (each) (Needs Plan Review and Building Permit)'. Permits come from the Inspection Department, at 734-466-2580 on the city's page.
If DTE serves your address (it's the only utility on the state's map for Livonia), the installer has 180 days after DTE approves the application to install and upload an inspection sticker signed by the local authority, and DTE says the whole process takes approximately six weeks.
Permits for interconnection and permits in Livonia
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: ask the installer who requests the plan review and the building permit, and when.
- 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.

| Electrical permit, alternative energy up to 50 kW, Battle Creek | $50.00 | Schedule effective July 1, 2026. Per-panel rows of $2.00 and $1.00 are also printed; ask the city whether both apply. |
| State electrical permit schedule, solar photovoltaic system | $75.00 application, then $2.00 or $1.00 per panel | LARA's state form applies only where the state inspects, and its column layout is ambiguous. |
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.
