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. This eliminates the need for customers to bring paper plans to our offices for many types of permits.

Use of ePlan is mandatory for the case types listed above with asterisks (*).  Site/Road Permit applications and plans are not accepted at DPIE through the mail.  Site/Road Applications and Plans may be submitted in person at 9400 Peppercorn Place, 1st Floor, 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.

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