Herndon is replacing its aging office parks with housing faster than it has in decades. Almost none of that housing can be bought. The town's own development list adds up to about 2,400 new homes either under construction or in review. Roughly one in eight is a unit someone could own, and only four are detached lots.
If you're comparing Herndon with other Silver Line towns, this changes what a search here looks like. New supply in Herndon mostly means renters moving in near the station. For buyers, the market will keep running on the same older houses and townhomes it has always relied on.
Counting the pipeline by who can own it
The Town of Herndon's development activity page lists every residential project under construction or in review. Sorted by ownership type, it looks like this:
| Project | Status on Town list | Rental apartments | For-sale units |
|---|---|---|---|
| Nell at 555 Herndon Parkway | Under construction | 399 | 0 |
| 575 Herndon Parkway | In review, council-approved April 28, 2026 | 525 | 0 |
| 535 Herndon Parkway | Draft plan under staff review | 400 | 0 |
| 13100 & 13150 Worldgate Drive | In review | 401 | 49 townhomes, 52 stacked condos |
| 250 Exchange Place | In review, council-approved June 23, 2026 | 400 | 62 stacked units |
| Park Place, 1155 Herndon Parkway | Under construction | 0 | 85 townhouses, 56 stacked condos |
| 801 Crestview | Draft site plan | 0 | 4 single-family lots |
| Total | 2,125 | 308 |
The for-sale total depends partly on which document you read. The Town's current page counts 85 townhouses at Park Place, but the 2023 architectural review presentation and FFXnow's October 2023 coverage described 55. With the lower figure, the for-sale count drops to about 278. Either way, the ratio barely changes.
Where the for-sale units actually are, and when they arrive
The ownership units are spread across three office-park sites. None of them has a published price, and only one has a construction start date.
- Park Place, behind H Mart. Stanley Martin is turning the Herndon Corporate Center office buildings at 1145–1175 Herndon Parkway into townhouses and stacked condos. The Town lists the project as under construction. The approved plan says phasing will depend on market conditions, and it gives no sales launch or completion date.
- Worldgate Drive. Council approved the plan to replace the vacant Worldgate offices on March 26, 2024, according to FFXnow. Two years later, the Town still lists it as in review, with no public delivery timeline. The apartment count has also changed. FFXnow reported 359 apartments in 2024, and the Town now lists 401 alongside the 49 townhomes and 52 stacked condos.
- 250 Exchange Place, the Van Buren Office Park. Rooney Properties won a unanimous zoning approval on June 23, 2026, to replace five office buildings on about 9.4 acres. The plan has three phases. Phase one covers demolition, new public streets and utility relocation. The stacked townhouses come next, then the 400-unit apartment building. A land use attorney for the owner told FFXnow that construction could start in 2027.
The rental side is moving faster. Nell at 555, right by the Herndon Metro station, was rising in May 2026. Its developer projected first move-ins in early 2027 and completion in late spring 2027, per FFXnow.
Every new ownership unit in this pipeline is attached. The only detached homes are four lots from a single re-subdivision on Crestview.
The houses already here aren't being replaced
The Town hired the consulting firm TPMA to study its housing, and the study was presented to council on February 17, 2026. It found that Herndon's housing is mostly single-family houses and one-unit townhomes. More than 70% of all units were built between 1970 and 2000, and fewer than 20% were built after 2000.
The study looked at the 3,700-plus units in the full residential pipeline and concluded that Herndon will have enough homes overall to meet demand for the next five and 10 years. It also found that the new supply leans heavily toward market-rate rental apartments. FFXnow quoted the report directly:
"While Herndon's existing housing stock has a majority of for-sale housing, there may be a mismatch in supply and demand in future years. Addressing this mismatch means identifying housing types and available land that would lend opportunities to meeting this demand."
Put that next to the age profile and you get a clear picture for anyone who wants to own a detached house or a traditional townhome in Herndon. The homes available to them were mostly built 25 to 55 years ago, and almost nothing new in that format is planned. The study notes that the town's housing is older than both Fairfax County's and Virginia's overall, and that "older homes have increased needs for major maintenance and repairs, renovations, and upgrades."
In practice, a Herndon home search is often a comparison of how and when each house was updated. Two colonials built a few years apart in the 1980s can be priced very differently depending on which one already has its big-ticket work done. Home inspections and seller disclosures matter more here because new construction isn't around to set a standard of comparison.
The regional numbers point the same direction
We couldn't find a verified Herndon-only sales figure for August or September 2026. The latest Northern Virginia regional release from the Northern Virginia Association of Realtors, published September 14, shows the same split happening across the wider market.
In August 2026, regional detached listings fell 8.5% from a year earlier, from 1,091 to 998. Attached inventory jumped 39.7%, from 1,384 to 1,934 listings. Condo listings rose 44.8% and townhome listings 29.9%. Detached homes dropped from about 28% of available inventory to about 21%. The regional median sold price was $765,000 in August, up 2.0% year over year, and homes averaged 26 days on market, unchanged from August 2025.
Herndon's pipeline is a local version of that pattern. Condo and townhome buyers across the region already have more listings to choose from. Over the next few years, Herndon will add more attached and stacked ownership units to that side of the market. Detached buyers get no new supply at all, in Herndon or across the region.
What this changes in a Herndon search
The impact depends on what kind of home you're shopping for.
- Detached homes. The supply is fixed at what's already built, and almost all of it dates from 1970 to 2000. In August 2026, detached listings were shrinking across Northern Virginia. Nothing in Herndon's pipeline adds to this category beyond four lots.
- Townhomes and condos. Resale inventory is the only option today. New stacked and townhouse units at Park Place, Worldgate and Exchange Place will follow, but none has a published price, and the Exchange Place schedule points to a 2027 start.
- Near-Metro living. The blocks closest to the station are being built as apartments. The 575 Herndon Parkway project will also deliver the eastern half of a planned promenade linking the Metro station to Herndon Parkway. The other half depends on later work at 593 Herndon Parkway.
For an owner thinking about selling a detached home, the same numbers look different. A shrinking regional pool of detached listings and no new detached construction in town mean less competition from comparable houses. Condition and presentation then decide where in the price range a particular house lands. We covered how that plays out in our earlier guide to buying a home in Herndon near the tech corridor and our piece on living near the Silver Line in Herndon.
The downtown parcel is still in court
The one downtown site that might have changed this picture is on hold. The nearly five-acre parcel at the northeast corner of Elden and Center streets was transferred to Comstock under a plan for apartments, an arts center, retail and a parking garage. Comstock withdrew from the project in December 2024. The Town then sued to get the land back.
In an opinion dated September 17, 2026, a Fairfax County Circuit Court judge ruled that the Town is not entitled to have the property returned. Comstock keeps control for now and has said it is still willing to work with officials on a mixed-use project. The Town filed objections on September 29 and says it is preserving its options, including an appeal, according to FFXnow's report.
A few common questions
Is Park Place selling now? The Town lists Park Place as under construction. We haven't found a published price range or sales launch date, and the approved plan ties phasing to market conditions.
Does the new apartment supply affect home prices in town? The town's housing study frames the new apartments as rental supply, separate from the for-sale market. It projects enough homes overall but a possible mismatch for ownership housing in future years.
Why are the new for-sale units stacked or attached? They're going on former office-park land along Herndon Parkway and Worldgate Drive, where each plan pairs a large apartment building with a smaller group of townhouse or stacked units.
If you're deciding between a 1980s Herndon colonial and waiting for a stacked townhouse along Herndon Parkway, I can pull recent comparable sales for the specific streets you're considering and help you compare an older home's update history against what's still on the drawing board. If you already own here, a home valuation will show where your house sits in a market where detached supply isn't growing. Reach out to Anthony C Ford, and Contact Anthony Anytime.
