How long does a home addition take in Fort Myer?
Natalie’s answer
“A home addition in Fort Myer typically takes 6 to 16 months end to end, with a median of around 11 months, covering everything from the first design conversation through permitting with Arlington County to the final day of construction, not just the time crews are on site.”
A home addition in Fort Myertypically runs 6 to 16 months from start to finish, with a median of around 11 months, figures drawn from 159 completed MOSS addition projects across the DMV region. That span covers three distinct phases: design and selections (usually 2 to 3 months),permitting and approvals (roughly 1 to 2 months), and on-site construction (often 3 to 10 months depending on scope). The build itself, while the most visible part, is only one chapter of the full timeline.
Where your project lands within that range depends on several factors specific to Fort Myer and Arlington County. A straightforward single-story bump-out moves faster than a two-story addition requiring structural engineering, new foundation work, or significant mechanical rerouting. Arlington County's Building Department typically processes standard residential permits in 5 to 10 business days, but if your home sits near Maywood or Aurora Highlands, neighborhoods with historic district oversight, exterior modifications may require an additional architectural review layer that extends the approval window. Long-lead materials like custom cabinetry and specialty windows can add weeks if not ordered early, and older housing stock common to the Fort Myer area sometimes surfaces surprises, outdated wiring, older plumbing configurations, or subfloor conditions, that require adjustment once walls open up.
MOSS's design-build model is specifically structured to compress the schedule wherever possible. Because our design and construction teams work as one unit, permit-ready drawings are submitted earlier in the process than a traditional architect-then-contractor approach allows. We also identify and order long-lead materials during the design phase so they arrive on-site in step with construction rather than creating mid-project delays. That coordination, combined with deep familiarity with Arlington County's submittal requirements, keeps your project moving efficiently from the first conversation through the final walkthrough.
