The Hunter Mill District, which includes Reston, is one of Fairfax County's three busiest areas for new housing development, according to the county's 2025 Demographics Report. The same data shows median home values reaching $752,378 and average apartment rents hitting $2,092 a month.
The report, published in June by the county's Department of Management and Budget, tallies 5,800 housing units in the development-plan stage countywide, 3,100 with approved plans, 2,650 under construction and 2,200 with permits issued but construction not yet underway. Hunter Mill, Providence and Dranesville districts account for the largest shares of that pipeline, though the report does not publish district-level unit counts.
The scale of activity around the Wiehle-Reston East Metro station offers a ground-level view of what those numbers look like. Comstock's Reston Station development spans nearly 90 acres and includes the 28-story JW Marriott Hotel and Residences tower that opened in September 2025, two BLVD-branded apartment high-rises with more than 400 units each and office towers housing Google, ICF International and CARFAX. The JW Marriott Residences recorded nearly $90 million in condominium sales since opening, including more than $12 million in the first quarter of 2026, according to Comstock.
Costs keep rising
Those county-level figures track with broader market pressure. The Northern Virginia Association of Realtors reported a median sold price of $812,012 across the region in May 2026, up 2.9% from a year earlier. Homes sold in an average of 15 days, and months of supply stood at 1.93, compared to 4.5 months nationally.
"Until inventory returns to more balanced conditions, competition will remain a defining feature of our local housing market," said Christina Rice, president-elect of the Northern Virginia Association of Realtors and an agent with Pearson Smith Realty.
Median household income in Fairfax County reached $154,545 in 2024, among the highest in the Washington region. But the gap between incomes and home prices helps explain another trend in the data.
More people leaving than arriving
More than 76,000 people filed tax returns from a new address outside Fairfax County in 2023, according to IRS migration data. Virginia Realtors' analysis attributed the outflow primarily to housing costs and affordability concerns.
The county's overall population still grew slightly, reaching an estimated 1,199,700 in 2025, an increase of about 3,200 from 2024. That 0.3% growth rate is far below the pace Fairfax experienced in the 1980s and 1990s.
