Do you need a permit to replace an electrical panel in Milwaukee?
Yes, and you cannot pull it yourself. Milwaukee's electrical code (MCO 222-13) says no electrical equipment may be installed, altered, renewed, replaced or connected without a permit, and the Department of Neighborhood Services (DNS) checklist puts it bluntly: Electrical work, all of it, needs a permit and the contractor must be licensed.
Wisconsin law lets an owner wire a home they own and live in, unless a local ordinance requires a license. Milwaukee does: MCO 222-1 limits that homeowner exemption to replacing an existing switch, receptacle or light fixture rated 20 amps or less. A panel change, service upgrade, subpanel or new circuit must be done by a state-licensed electrical contractor, whose permit application is signed by the supervising master electrician. The rest is state code: Milwaukee adopts the Wisconsin electrical rules (SPS 305, 316 and 318).
How much is an electrical panel permit in Milwaukee?
Electrical permits are itemized under MCO 200-33-11. The lines that matter for panel work are a service with one service switch up to 400 amps: $130, each additional service switch $35, and a feeder up to 400 amps $55. A one- or two-family electrical permit has a $100 minimum, every electrical permit adds a $25 processing fee, and DNS adds a 1.6% training and technology surcharge to the permit fee.
- New 100 A subpanel fed from the main panel: the $55 feeder line is under the minimum, so $100 + $1.60 + $25 = $126.60.
- Upgrading a house from 100 A to 200 A service with a new main panel: $130 + $2.08 + $25 = $157.08.
- Duplex service with two service switches: $130 + $35 = $165, plus $2.64 and $25 = $192.64.
New circuits added on the same permit are extra: $3 per outlet, switch or receptacle, $10 per light fixture, and $25 to $30 lines for ranges, dryers and air conditioners. Missed inspections cost money too: $110 for failing to call for an inspection, and reinspection fees of $110, $140 and then $220 each.

What happens at inspection?
The licensee who did the work must notify DNS when it is complete, and any wiring that will be concealed must be inspected and approved before it is covered. Call Electrical Inspection at (414) 286-2532 with questions. Permits are applied for and paid online through the Land Management System; construction must start and have an inspection within 180 days, and permits expire after two years.
