Home Projects: When Do You Need a Permit?


Spring is in the air, and many homeowners may be planning home improvements and renovations in the coming weeks and months.

Montgomery County Department of Permitting Services (DPS) staff members are available to answer questions about when a permit is needed and when you do not need a permit for home projects.

In Montgomery County, a permit is not required for caulking, painting, wallpapering, replacing a faucet, installing countertops, installing flooring, replacing siding, replacing the roof covering, and replacing window screens.

A permit is generally required prior to reconstruction or renovation to an existing structure other than a repair. For example, permits are required when installing an accessory structure, deck, fence (unless it replaces a permitted fence in the same location, is the same height and same materials), gazebo, swimming pool and shed.

DPS also provides guidance on its Residential Alterations webpage to help customers know when they may need a permit. Other resources to check online are posted on the DPS Homeowners webpage. If you live in a municipality or homeowners association, be sure and check the specific bylaws and regulations.

DPS staff members are available to answer questions about when a permit is needed and when one is not necessary. Questions can be directed by calling the County's call center at 311 (if outside the County, call 240-777-0311). The call center can make connections with DPS staff. Residents or business representatives also can stop by DPS offices at 2425 Reedie Drive (seventh floor) in Wheaton from 7:30 a.m.-4 p.m. Monday-Friday. No appointment is necessary.
