Residential Accessory Structures Permit & Inspection Process
A permit is required prior to the construction or modification of any accessory structure or building. These structures or buildings are located on the same lot, are detached from the dwelling and their use is related to the use of the dwelling.
Accessory structures or buildings include but are not limited to: detached garages, sheds, barns, gazebos, pool houses, portable storage and sea containers.
An accessory structure or building on a residential lot must be in the rear yard.
If your project includes an accessory dwelling unit (ADU) such as accessory apartment, granny pod, backyard cottage or carriage house, among others, please read the applicable requirements.

A permit is required prior to construction of an accessory structure.
If a code violation is reported at your property, an inspector will order appropriate corrective action which may include obtaining a permit.
In many circumstances, electrical, mechanical, public right-of-way, well, septic, and/or fire protection permits are required to complete the project. You will also need to make sure that your project conforms to Zoning requirements.
Many of the subdivision and developments in Montgomery County have private deed restrictions and covenants regulating construction. The County does not enforce covenants and deed restrictions. You may obtain information from your homeowner’s or civic association. You may also need a permit or other permission if you live a Montgomery County municipality that requires it.
Eligible applications may be reviewed through our Fast Track program, which may take three to five days.
Please refer to our fee schedule for information regarding fees associated with this permit application type.
Homeowners may apply for the building permit in their own name; however, if a contractor is to perform the work, DPS strongly suggests that the contractor be listed on the permit as the party responsible for the work. A contractor must have a Montgomery County New Home Builder’s (BC) license to obtain a permit.
Please see our list of required inspections associated with this permit application type.
