Permits & inspections in Montgomery County

The paperwork is the part most contractors gloss over.

A finished basement needs a building permit and, in almost every case, electrical, plumbing and mechanical permits alongside it. Two code requirements decide whether the space is legal: any room used for sleeping needs proper emergency egress, and habitable space needs a minimum finished ceiling height. The framing and rough-in inspection has to pass before insulation and drywall — get that wrong and the drywall comes back off.

Your Kensington permit goes through the Montgomery County Department of Permitting Services. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.

What we find in Kensington homes

The house decides half the scope.

Kensington's core is small early-20th-century housing — bungalows and Victorians on tight lots. Kitchens and baths in these homes are usually the original footprint, which is why most projects here become layout changes rather than swaps, and why the permit set is larger than homeowners expect.

Can I put a bedroom in my finished basement?

Only with proper emergency egress — that means a code-compliant egress window and window well, or a walkout. It is the single most common reason a basement bedroom fails inspection or gets flagged at resale. We settle it during design, before framing, because retrofitting egress into finished walls is expensive.
