An addition is the one project where zoning can stop you before design starts. We are a licensed contractor in Virginia (Class A #2705183185) — we pull the permits through the City of Alexandria Department of Code Administration, 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 Alexandria permit goes through the City of Alexandria Department of Code Administration. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.
Alexandria is an independent city with its own permit office, and Old Town's Board of Architectural Review must approve exterior changes in the historic district — materials and windows included. That review runs on its own calendar, so for anything visible from the street it goes first, not last.
Old Town is 18th- and 19th-century masonry and frame rowhouses; outside it, Alexandria is largely mid-century and newer. The rowhouses are party-wall construction, which changes how structural work, plumbing stacks and ventilation all get handled.

Most Alexandria projects land in the $180 – $340 / sq ft range. That is a planning range for City of Alexandria, 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.
