Home Additions in Wheaton
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.

- A written, line-item scope for your Wheaton project before anyone swings a hammer
- Permits pulled through the Montgomery County Department of Permitting Services under MHIC #111971
- One project manager from demolition to final walkthrough
Two fields and one question. A specialist calls you back to confirm a time.
The paperwork is the part most contractors gloss over.
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 Wheaton 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.
Wheaton is unincorporated Montgomery County, so Montgomery County Department of Permitting Services handles the permit, the plan review and every inspection — there is no separate Wheaton authority. Electrical is its own permit under county rules and has to be pulled by a licensed master electrician, which is the step most often missed on a basement or kitchen job.
The house decides half the scope.
Wheaton is dominated by 1940s–1960s brick ramblers and split-levels on regular lots — a genuinely good stock to work with, because the framing is sound and the layouts take a rear addition or a basement suite well. The recurring issues are original 100 amp service, ductwork sized for the house as built rather than as extended, and basements with no egress window, which is the single thing that decides whether a lower-level bedroom is legal.

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.

What should I expect in a Wheaton home?
Wheaton is dominated by 1940s–1960s brick ramblers and split-levels on regular lots — a genuinely good stock to work with, because the framing is sound and the layouts take a rear addition or a basement suite well. The recurring issues are original 100 amp service, ductwork sized for the house as built rather than as extended, and basements with no egress window, which is the single thing that decides whether a lower-level bedroom is legal.
What does home additions cost in Wheaton?
Most Wheaton 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.
Is the Wheaton walkthrough and estimate free?
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.
How long does an addition actually take?
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.
