Should you buy before Fairfax’s New Coppermine Commons townhomes add supply?
Not for that reason alone. Fairfax County’s Board of Supervisors unanimously approved the rezoning on August 25, 2026, to replace the Coppermine Commons III office building with 98 townhomes near Innovation Center Metro. Fairfax’s New Coppermine Commons is a real addition to the area, but no delivery date or pricing has been confirmed, so a purchase today should rest on the home and your timeline, not a guess about future supply.
Key Takeaways
- Fairfax County approved 98 townhomes at 13851 Sunrise Valley Drive on August 25, 2026: 40 conventional townhomes and 58 stacked townhomes.
- Twelve of the 98 homes, about 12.5%, are designated affordable for households earning 60% or less of area median income.
- Fairfax County had 2,326 active listings on September 30, up 36% from a year earlier, so buyers already have more choice than last year.
- Homes that closed in Fairfax County in September spent an average of 26 days between listing and ratified contract.
- The approval history flagged sidewalk gaps and missing ADA-compliant curb ramps, so walk the real route to the station before you pay for “near Metro.”
What does Fairfax’s New Coppermine Commons approval actually change for buyers?
It adds a future batch of new attached homes in the McNair area south of Herndon, on a site that is an office redevelopment rather than open land. It does not, by itself, change what the homes around it are worth tomorrow. Here is what the reporting confirms, per FFXnow’s coverage of the approval.

Just as important is what I haven’t seen confirmed: a construction start, a delivery date, floor plans, square footage, parking, HOA terms, or pricing. Until those exist, anyone telling you exactly how this project will move nearby prices is guessing.
Why does the 40 conventional and 58 stacked mix matter?
More than half the homes (58 of 98) are stacked townhomes, so this isn’t a copy of the multilevel, conventional townhouse communities many buyers picture in Herndon. Stacked and conventional units live differently. Layout, stairs, parking arrangements, and monthly fees can all vary.
When I help a buyer compare a new stacked unit with an established conventional townhouse, I line up the layouts side by side and look at how the home functions day to day. A price per square foot alone won’t tell you that.
Will the 12 affordable homes be for sale or for rent?
The reporting I’ve seen doesn’t settle that. If you think you might qualify, that is worth confirming early, and I can point you toward the right county records.
What happened with the sidewalk and pedestrian concerns?
The Planning Commission delayed consideration in early July 2026 after county transportation staff raised concerns.
“Addressed in the plan” is not the same as “built and walkable.” I haven’t seen a construction schedule or confirmation that every pedestrian improvement is in place, which is why I tell buyers to verify the route themselves.
How does it compare with McNair, Herndon, and established neighborhoods near Innovation Center Metro?
Compare them on property and location attributes: housing type, age, layout, walking route to the station, and fees. You can’t compare them on price yet, because the new homes have no announced price. The project’s own site is near Innovation Center Metro, but the sources I have don’t give a verified walking distance or travel time.
What should you check on any home that says “near Metro”?
I walk these routes with my clients. Do it at the time of day you’d actually commute:
- The walking route to Innovation Center Metro. Are the sidewalks continuous? Are the crossings and curb ramps usable?
- Bus stops and retail. Check how far they are on foot, not as the crow flies.
- Sunrise Valley Drive. Look at how you’d cross it, how fast traffic moves, and where you’d actually walk.
- The home itself. Look at layout, stairs, storage, parking, and how much outdoor space comes with it.
- The monthly picture. Ask for HOA terms in writing so you can compare against an established community’s fees.
I covered the broader trade-offs in Is It Worth Buying Near Metro?, and the same logic applies here. Metro proximity is only worth paying for if the walk is something you’d actually do.
Will the new townhomes hurt nearby resale values?
Nobody can say that yet. Resale values depend on condition, layout, location, and what else is for sale when you list. A single 98-unit project is one factor, and it arrives on an unknown schedule. The countywide data below shows the broader backdrop, but it doesn’t isolate McNair, Herndon, or Innovation Center attached-home inventory, so don’t use it to predict this project’s effect.
Should you buy now or wait for the Coppermine Commons townhomes?
Buy now if you find a home that fits your budget, commute, and plans. Wait only if the new stacked layout is what you want, and even then, don’t count on a bargain, because pricing hasn’t been announced. Supply is already rising across the county, which gives you more leverage today than a year ago.

Those are the most recent figures available, from FFXnow’s September 2026 market report. They’re countywide, so they tell you the market is giving buyers more options. They don’t tell you what a McNair townhouse will sell for. For the broader question of timing, I’d read Wondering If You Should Still Buy a Home Right Now? alongside this.
When does waiting make sense?
- You specifically want a new-construction stacked layout and your current housing is flexible.
- You’d qualify for an affordable unit and want to confirm the program details first.
- Your must-haves aren’t being met by what’s on the market today.
When does buying now make more sense?
- You’ve found a home you’d be happy in for years, and the walking route and fees check out.
- Your lease or sale timeline is already pushing you.
- You want a conventional multilevel layout, which only 40 of these 98 homes will offer.
If you’re also weighing resale homes in other parts of the county, my post on what buyers want in western Fairfax homes shows how I think about features that hold up over time.
Fairfax’s New Coppermine Commons is worth tracking, not worth panicking over. Your best move is a side-by-side comparison of two or three real homes, with the walking route tested and the monthly fees in writing. That’s exactly what I do for buyers before we write an offer, and I’ll pull the Fairfax County records on this project for you. Schedule a consultation and we’ll compare your options.

FAQ
When will the 98 Coppermine Commons townhomes be built and available to buy?
No delivery date has been confirmed in the reporting I’ve seen. The rezoning was approved August 25, 2026, but construction phasing and sales timing would come from the developer and Fairfax County’s development records. Don’t plan a move around a date nobody has published.
How close will the new townhomes be to Innovation Center Metro?
They’re near the station, but I don’t have a verified walking distance or travel time. Walk the route yourself to judge it. The approval history included sidewalk-connectivity and curb-ramp concerns, so the actual route matters.
Are the new homes conventional townhouses or stacked townhouses?
Both. The plan includes 40 conventional townhomes and 58 stacked townhomes.
Will the 12 affordable homes be for sale or rent?
That should be verified in the approval documents. Twelve homes (about 12.5% of the project) are designated for households earning 60% or less of area median income, but the available reporting doesn’t establish the final sale or rental structure.
Will additional townhouse developments be approved nearby?
I can’t predict that. Each rezoning goes through Fairfax County’s own review, as this one did, with its own transportation and design questions. If a specific parcel near you matters to your decision, I can help you look up its status in county records.
