Residential Permit Process

EXPEDITED PERMIT PROCESS (most residential installs are eligible for the expedited permit process)

In most cases, residential solar projects may be eligible for an expedited solar permit. If the project meets the following criteria, the expedited permit can be used which takes the place of a separate electric and building permits.

  • Solar electric (PV) system of less than 10 kilowatts
  • 1 or 2 family dwelling
  • Solar panels are flush-mounted on the roof
  • Total load is less than 5 pounds per square foot

Expedited solar permits cost $70 (with a $5 processing fee). Any additional service upgrades, outlets or switches or feeder/sub feeder changes will cost additional. Permit applications must include (1) a line diagram and (2) spec sheets.

Please use this planning worksheet to determine if the planned project meets the requirements for the expedited permit. If so, the expedited permit can be used. Click here for a paper copy of the permit that you can use as reference: expedited permit.

Please note: The expedited solar permits must be completed via the City's LMS (online) website.  Stamped structural drawings are not required if your project meets the criteria above for the expedited permit. 


All solar projects in the City of Milwaukee are required to have:

All permits must be approved and issued before starting the solar installation.

The following is the permitting process:
