Residential Permit Process

Expedited Residential 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 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. 

Please note: The expedited solar permits must be completed via the City's LMS (online) website. 

Please note: Stamped structural drawings are not required if your project meets the criteria above for the expedited permit. 


Standard Residential Permit Process

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

  • Electrical or plumbing permit
  • Building permit

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

The following is the standard residential permitting process:

  1. Installer with proper credentials compiles submittal documents (see Solar Permit Worksheet) to support the permit application
  2. Installer submits ESPV permit application and uploads supporting documentation via the LMS Land Management System at milwaukee.gov/LMS, or visits the development center via walk-in service or appointment to meet with a plan examiner
  3. A Plan Examiner reviews and approves application and supporting documents
  4. Installer pays all applicable permit fees
  5. Permit is issued

All solar projects in the City of Milwaukee are required to have a solar permit (ESPV).

If an alteration to the roof structure is required to support the proposed solar array, a building permit will be required.

Please see the Department of Neighborhood Services Residential Solar Permit Process Worksheet for more information.
