Process Overview

Once the application is completed online, the customer’s information is entered directly into the County’s permitting system. After the permit case has been processed, customers can upload site/road plans for review via our ePlan online application.

Use of ePlan is mandatory for the case types listed above with asterisks (*).  Site/Road Permit applications and plans are not accepted through the mail.  Site/Road Applications and Plans may be left in the drop box in front of DPIE Headquarters at 9400 Peppercorn Place, Largo, MD 20774 and/or through our electronic plan (ePlan) review process.  For questions pertaining to the ePlan review and submission process, please e-mail us at or call 301-636-2060.  For instructions on using our ePlan system, please view the User Guides at the bottom of this page or visit the ePlan page for additional information.

Revisions to previously issued permits may also be processed using ePlan. Please review Techno-gram 002-2020 for further guidance on processing permit revisions.
