An addition is the one project where zoning can stop you before design starts. We are a licensed contractor in Maryland (MHIC #111971) — we pull the permits through the Montgomery County Department of Permitting Services, coordinate the licensed trades, and hand you a written line-item scope before demolition starts.
An addition starts with zoning, not construction: setbacks, lot coverage and height limits get reviewed before a building permit is issued, and in some neighborhoods there is a stormwater or historic review on top. Then come the footing and foundation inspections, which have to pass before backfill. This is the longest-lead permit of any project we do, and it is why we start the paperwork while the design is still being drawn.
Your Germantown 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.
Germantown is Montgomery County jurisdiction throughout and, unlike the county's outer edges, it is almost entirely on public water and sewer — so septic capacity is not the constraint here. The constraint is the HOA: nearly every neighborhood has architectural review for exterior work, and it runs on its own calendar alongside the county permit.
Germantown is one of the newest large-scale housing stocks in the county — mostly 1980s through 2000s single-family, townhome and duplex construction. That has a specific consequence worth knowing: builders in that era commonly roughed in a basement bath and left the space unfinished, so a Germantown basement finish is often cheaper per square foot than the same job in an older house, because the plumbing stub, the egress and the ceiling height are frequently already there. We confirm what is actually stubbed at the walkthrough rather than assuming it.

Most Germantown projects land in the $180 – $340 / sq ft range. That is a planning range for Montgomery County, not a quote — your written price comes after a free on-site walkthrough.
Yes. The walkthrough and the written scope are free and yours to keep whether or not you hire us. There is no design fee and no consultation invoice.
The build is rarely the long part — permitting and zoning review are. Expect the approval phase to run in parallel with final design, and expect us to give you a schedule that names the permit milestone rather than hiding it. We will tell you at the walkthrough if your lot has a setback or coverage problem, because that changes the whole conversation.
