Medical space is the hardest tenant work there is — plumbing in every wall, air handling that has to meet code, and inspections regular offices never see. Here's an honest guide to cost, schedule, and process for practices building out in Northern Virginia.
A standard DC-area office fit-out runs roughly $130–$300 per square foot depending on grade. Medical space starts where office space ends. Published cost guides put medical and dental fit-outs broadly in the $200–$400+ per square foot range, and the reasons are structural, not cosmetic: sinks and med-gas rough-ins multiply plumbing runs; exam and procedure rooms need dedicated exhaust, filtration, and sometimes pressure relationships; lead shielding for imaging; emergency power for refrigerated storage; and casework built to be scrubbed daily for a decade.
Specialty drives the spread. A behavioral-health or telehealth suite can land near ordinary office numbers. A general practice or dental office with six operatories sits mid-band. Imaging, ambulatory surgery, and lab-adjacent space climb past it — if your program includes a lab component, read about our lab and cleanroom build-out work, because the mechanical logic is similar.
1. Jurisdiction matters. Fairfax County, Arlington, Alexandria, Loudoun, and Prince William each run their own plan review and inspections, and their timelines differ meaningfully. Fairfax offers expedited review programs for qualifying projects; Arlington's occupied-building logistics tend to be the tighter constraint. Whoever you hire should be able to tell you, before design is done, how your county sequences trade inspections — because that sequencing is your schedule.
2. The Virginia USBC governs, plus healthcare overlays. Your build-out is reviewed under the Virginia Uniform Statewide Building Code, and depending on what you do in the space — outpatient procedures, imaging, pharmacy storage — additional state licensure and radiation-safety requirements attach. These are design decisions with construction consequences: discovering a required pressure relationship after ductwork is installed is the expensive way to learn it.
3. Landlord TI allowances rarely cover medical scope. Allowances in the NoVA market are typically negotiated against office-grade build-outs. The delta between the allowance and a real medical fit-out budget is the number that should drive your lease negotiation — model it before you sign, not after.
For a typical 2,500–5,000 SF practice suite: design and engineering, 6–10 weeks; permitting, 4–10 weeks depending on county; construction, 12–20 weeks. Call it seven months to a year from signed lease to seeing patients, with specialty spaces on the long end. The single best schedule protection is complete MEP engineering before permit submission — medical projects that stall in plan review almost always stall on mechanical comments.
Ask three questions. First, who is actually managing the job — a project manager you've met, or a rotating cast? At OAK Builders, the principal runs the work: Sean Abadian, PMP, spent 15+ years managing federal construction — $133M across 37 projects for agencies including GSA and the Pentagon — where documentation, inspection readiness, and schedule discipline weren't optional. That's the standard we bring to a six-operatory dental suite in Fairfax.
Second, demand a line-item estimate on CSI divisions with explicit inclusions, exclusions, and unit prices for likely changes. Medical scope hides in the walls; a lump sum with no breakdown means you'll meet that scope later as change orders.
Third, ask how they handle occupied buildings. Most medical build-outs happen in occupied professional buildings with working practices next door. Phasing, after-hours work for noisy trades, and infection-control-minded dust containment should be priced in from day one — this is core to how we run tenant improvement work across our commercial services.
One more thing worth checking in older NoVA buildings: water. If the suite you're leasing has a history of leaks or sits below grade, resolve it before you put drywall and casework over it — our commercial waterproofing division investigates and fixes building-envelope problems so your build-out isn't ruined by someone else's deferred maintenance.
Plan on the $200–$400+ per square foot range for construction depending on specialty — behavioral health at the low end, dental and general practice mid-band, imaging and procedure-heavy suites above it. Furniture, medical equipment, cabling, and design fees are additional. Get a line-item estimate before you rely on any per-foot number.
Roughly seven months to a year for a typical suite: 6–10 weeks of design, 4–10 weeks of permitting depending on the county, and 12–20 weeks of construction. Complete MEP engineering before permit submission is the best way to protect the schedule.
Usually not fully. Allowances are typically set against office-grade construction, and medical scope — plumbing, HVAC, shielding, casework — runs well past it. Model the gap before signing the lease so it's a negotiating point instead of a surprise.
Yes. Permitting and inspection coordination across Fairfax, Arlington, Alexandria, Loudoun, Prince William, and the rest of the DMV is included in our general contracting scope, and we sequence the work around each county's inspection order.
