Residential Alterations Permit & Inspection Process
A permit is required prior to reconstruction or renovation to an existing structure other than a repair. A permit is not required for painting, wallpapering, replacing a faucet, installing countertops, installing hardwood floors or tiles or carpeting if no structural changes are performed. Reconstruction includes partial demolition (that does not require a demolition permit) and rebuilding a structure or building.
If your construction project includes both alteration and addition to the structure you will receive an Add/Alter permit.
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.

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 and 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 will be reviewed through our Fast Track program, which can result in a permit in three to five days.
Please refer to our list of guidelines for information that must be included on your plans.
Please refer to our fee schedule for information regarding fees associated with this permit application process.
Homeowners may apply for the alteration 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 Maryland Home Improvement Commission (MHIC) license to obtain a permit.
