Electrical Registrations and Licenses

Baltimore County has expanded the online application process. Applications for new/reciprocal or renewal of an electrical master general registration or for new/exam, reciprocal or renewal of a restricted low voltage license must be completed online.

No person shall install, repair, maintain or erect any of the electrical apparatus or devices listed below without having obtained a license as required by the County.

  • Appliances
  • Conduits
  • Electrical wiring
  • Elevators 
  • Fixtures
  • Heating equipment that is electrically-operated
  • Machinery
  • Motors
  • Signs
  • Any other electrical apparatus or device in or about any premises in Baltimore County

Exceptions to those persons include:

  • Utility companies regulated by the state public service commission
  • Radio and electronic experimenters and amateurs where no change in existing wiring is necessary, unless changes are authorized by the County's Electrical Administrative Board, and in each case the applicant must file an application with the Department for a permit and inspections
  • Employees of the United States government, when engaged in performance of their official duties only

Types of Electrical Registration and Licenses

Review the types of registration and licenses issued by Baltimore County and the requirements for each before submitting an application.  Only the License or Registration holder or the person applying for an Exam can submit an application for a License or Registration.

Master General Electrical Registration

Restricted License (Low Voltage)

A Restricted License authorizes the holder thereof to install, maintain and repair low-voltage equipment and wiring operating at 50 volts or less. 

Limited License

A Limited License limits the license holder to represent and perform work in one industrial type building in Baltimore County and authorizes the holder thereof to install, repair, maintain or erect any of the following, but only on the premises of their employer in Baltimore County, they cannot perform any work on this list for the public at all.

Apply for or Renew a License or Registration

Applications for New or Renewal of Electrical Registration, Restricted Low Voltage and Limited License must be applied for by the Electrician only. Applications will not be accepted if submitted by company staff or proxies. Your user ID and email will ensure that only you have access to your license account information. To learn more about the application process and to apply (step three), read the steps below.

Request Changes to Your Electrical License

Complete the change form in order to change information on your Baltimore County Electrical registration or license. Forward all information changes, including phone numbers, to the Baltimore County Electrical Inspection Office. Failure to report this information immediately could result in a hold on the issuance of permits.

How to Protect Your License

Be sure that your online registration and license account is only accessible by you. If your business account is used by others to submit permit applications on your behalf, you should not use that account for the license and registration. With your online registration or license account, Baltimore County will be able to notify you via email each time a permit is issued using your registration or license number. You can contact the Electrical Inspection Office if a permit was not approved by you.
