Do I need a permit for a bathroom renovation in Kensington?
Natalie’s answer
“Most bathroom renovations in Kensington require a permit through Montgomery County's Department of Permitting Services when they involve electrical, plumbing, structural, or mechanical work, while purely cosmetic updates like repainting or swapping fixtures typically do not; MOSS handles the entire permitting process as part of its design-build service.”
In Kensington, most bathroom renovationsdo require permits through Montgomery County's Department of Permitting Services. Work that triggers a permit includes any structural changes (moving or removing walls), electrical upgrades or new circuits, plumbing alterations (relocating fixtures, adding drains or supply lines), gas line work, mechanical ventilation changes, and modifications affecting egress. Purely cosmetic updates, swapping out a vanity mirror, repainting, or replacing a faucet in place, generally do not require a permit. Montgomery County's standard review timeline runs 10 to 15 business days for an initial plan review, with the fullprocess from complete submission to permit issuance typically spanning 20 to 30 business days.
As part of MOSS's design-buildprocess, we handle every step of the permitting process on your behalf. Our team prepares the scaled drawings and assembles the documentation required for submission to Montgomery County's Department of Permitting Services, files the application, responds to any reviewer comments, and schedules all required inspections at the appropriate stages of construction. You never have to navigate the permit office or track down forms, that coordination is built into how we work.
Permitting protects you in two important ways: it ensures the finished work meets current safety codes, and it keeps your home's records clean for any future sale or refinancing. If your property falls within Kensington's Historic District, exterior alterations also require review by the Historic Preservation Commission, and MOSS's experience working with similar districts across Montgomery County means we know how to present proposals that satisfy preservation guidelines without compromising your design goals. If your neighborhood has an active homeowners association with an architectural review committee, we recommend identifying those requirements early, and we'll factor that process into our project timeline as well.
