Arlington, for tenants.

The paradox, stated plainly

Arlington's four major corridors were the only submarkets in Northern Virginia asking more than $40 per square foot. They also carry the highest vacancy in the region. Both things are true at once, and most tenants only find out about the first one.

Rosslyn — $44.73 per square foot, 21.7 percent vacancy. The highest asking rent in Northern Virginia, and the tightest of the Arlington corridors. Views, Metro, and a short hop to Georgetown.

Ballston — $41.89 per square foot, 29.6 percent vacancy. Nearly a third empty at a rate almost five dollars above the regional average.

National Landing — $41.29 per square foot, 25.7 percent vacancy. Also carrying the highest sublease availability rate in the region at 3.58 percent, which is a second, quieter layer of supply.

Clarendon, Courthouse and Virginia Square — $40.62 per square foot, 34.2 percent vacancy. A third of the space is empty and the asking rate is still four dollars above the Northern Virginia average of $36.99.

A landlord asking $40 in a building that is a third empty is not pricing from strength. He is holding a face rate for the comparables and paying for occupancy in the concession package, where nobody publishes it. That is the whole opportunity in Arlington, and it does not show up in an asking rent.

Why the rate holds anyway

Two forces keep Arlington's asking rents high while the space sits.

The first is flight to quality. Tenants are concentrating in the best buildings and leaving the secondary stock behind, which drags vacancy up without dragging the quoted rate down — the good space is genuinely competitive and the rest is genuinely not. Northern Virginia's Class A average rose to $38.21 per square foot from $36.55 a year earlier while overall vacancy stayed high.

The second is that tenants have been looking west. Reston and Herndon have dominated recent leasing activity, and the Dulles corridor is where the defense and technology demand has concentrated. Arlington is not losing to a cheaper Arlington; it is losing to Fairfax County.

For a tenant who actually wants to be in Arlington — and for a law firm, an association, or anyone whose work touches the federal government, Arlington is often the right answer — that combination is favourable. You are negotiating in a market where the competition for your tenancy is real and the published rate is a fiction. Contractors should read our lease playbook for government contractors before touring.

The supply is being removed, not filled

Arlington's vacancy is improving in part because office buildings are being taken out of the inventory rather than leased.

Roughly 2.61 million square feet of office in the Rosslyn to Ballston corridor has been approved for conversion. A working example: 3601 Wilson Boulevard, a 121,200 square foot office building one block from Virginia Square Metro, is being converted by Gilbane Development into the Renley, 94 apartments with ground floor retail. Construction started in June 2026 with delivery expected in April 2027.

Two consequences for a tenant. First, the vacancy figure you are quoted is being flattered by demolition and conversion, so it overstates how much genuine choice you have. Second, and more immediately: if your building is a plausible conversion candidate, your renewal negotiation is not really about rent. It is about whether ownership intends to keep operating the building at all.

Signs your building is on that list: built in the 1970s or 1980s, a floor plate that would suit apartments, a Metro-proximate site worth more than the improvements, an owner who has stopped investing in common areas, and neighbours whose leases are not being renewed. Ask directly. An owner with no conversion plans says so immediately.

What to actually negotiate here

In a market at 30 percent vacancy with rates that will not move, the face rate is the wrong thing to fight about. Push on everything else.

The concession package. Free rent and tenant improvement dollars are where a landlord in a third-empty building can move without marking down every comparable in his own asset. This is where the money is.

Term flexibility. Termination rights, contraction options and expansion rights are cheaper to obtain in a soft market than in a tight one, and they are worth more over ten years than a dollar or two of rent.

The base year and the gross-up. Arlington buildings running well below full occupancy are exactly the case where an ungrossed-up base year quietly costs you money as the building fills.

A direct answer on ownership's plans. In a corridor with 2.61 million square feet of approved conversions, this is a real diligence item rather than a theoretical one.

What this means for a tenant searching now

Arlington is the most expensive place to lease in Northern Virginia on paper and one of the most negotiable in practice. The gap between those two statements is where a tenant representative earns the fee.

If you are comparing Arlington against Reston or Tysons on asking rent alone, you will conclude Arlington is unaffordable and you will probably be wrong. Compare on net effective rent, with the concession package priced in, and the ranking frequently reverses.
