Building Permits

Building Permit Application Form Completed Online

Building Permit applications are completed online. Please go to Online Permit Applications; enter the information directly into the County’s Permitting System.

Once the application is completed online, the customer’s information is entered directly into the County’s permitting system. In addition, customers can upload building plans for review via our ePlan online application system.

Revisions and applications for blocks of Building Permits that include more than four case numbers will continue to be accepted for processing using the appropriate forms (i.e., Application for Building Plan Examination and Permit, Transmittal, Sign Permit Application and/or Volume Form). If you have questions about the process, please call 301-636-2050.

Building Permit Applications and Plans are not accepted through the mail. Building 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 301-636-2050. 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.
