Alexandria, Virginia can now say its office vacancy rate is 18.8 percent, down from 21.6 percent a year earlier, and better than Northern Virginia’s 20.1 percent. That is a real sentence, it is accurate, and it will appear in every economic development deck the city produces for the next twelve months.
Here is the other real sentence from the same report. Over the first half of 2026 Alexandria posted negative net absorption of 160,400 square feet, meaning tenants gave back considerably more space than they took, across an inventory of about eighteen million square feet. The wider region absorbed a positive 302,274 square feet over the same period.
So the vacancy rate improved while occupancy fell. Both numbers come from the Alexandria Economic Development Partnership’s own mid-year report. Neither is spun. They simply measure different things, and the difference is the whole article.
The explanation is in the denominator. A vacancy rate is empty space divided by total space, and you can improve it either by filling space or by deleting space from the count. Alexandria has been doing the second. Construction has started on converting the long-vacant Victory Center at 5001 Eisenhower Avenue into housing, which removes obsolete floorplate from the office inventory entirely. The other major factor was retaining the National Science Foundation, which moved in May into a 386,600 square foot building previously occupied by the Patent and Trademark Office.
There is a further detail that matters for anyone actually deciding where to put a business. Most of the year-on-year improvement had already landed by January, when the rate stood at 18.9 percent. In six months it has moved a tenth of a point.
And the submarkets disagree violently with each other. Old Town and Old Town North, the largest submarket at around 7.5 million square feet, was the only one where vacancy rose, hitting 15.5 percent and giving back 102,789 square feet, the weakest showing in the city. Carlyle has the highest vacancy at 27.7 percent, improved from 29.1. The West End came down to 16.9 percent and was the only submarket to add occupied space, at 14,157 square feet. Potomac Yard registered zero vacancy across 908,527 square feet.
Zero and 27.7 percent, in the same city, in the same report, averaging to a number that describes neither of them.
Now, coffee, because this is the single most expensive mistake in siting a shop.
Nobody opens a cafe in a city. They open it on a corner. The catchment of a coffee shop is measured in walking minutes, and a person working in Potomac Yard will never buy a flat white in Carlyle, because it is not lunch, it is a trip. A citywide vacancy figure tells you approximately nothing about whether the forty desks nearest your door are occupied on a Tuesday, and the forty desks nearest your door are your entire business.
Which is why the Old Town number should worry anyone trading there far more than the headline should reassure them. That is the submarket with the largest inventory, the most established street trade, and the only vacancy line moving the wrong way. Meanwhile the West End, quietly, was the only place in the city where more people showed up to work than left.
Keeping the National Science Foundation was genuinely good work, and 386,600 square feet of retained federal tenancy is a serious win for the city’s tax base and for every business within walking distance of that building.
The rate went down because a building stopped being an office.
Nobody opens on an average.
