Permit Center Training Resources

Having trouble navigating Permit Center? We have a training document to help!

In June 2024, Maricopa County launched its online permitting system, Permit Center. Permit Center is designed to better serve residents, developers, contractors, consultants, and anyone else doing business with Maricopa County. It has consolidated various existing permitting systems used across multiple County departments into a single, comprehensive platform. All new permit and plan applications are now submitted through Permit Center.

While the new Permit Center platform provides expanded functionality, with all new technology comes a learning curve. For this reason, Maricopa County created a Training Resources webpage. The training documents cover topics such as resubmitting a file and creating a main contact/company account to enable company-wide access to permits in progress.

Can’t find the help you need? Submit requests for specific training documents to be created and posted to our website by emailing ESD@Maricopa.gov.
