The building's own benchmarking filing
Energy performance
From the building's own filing under its city's benchmarking ordinance, latest of 2 years on record.

It is a self-reported figure, verified by the city only to the extent the ordinance requires.
Federal lease inventory — actual rent paid
Leases on public record
| Lease | Rentable sq ft | Annual rent | $/sq ft | Term | Options left |
|---|---|---|---|---|---|
| LDC00162 | 473,000 | $24,312,797 | $51.40 | Jul 2020 → Jul 2035 | 4 · 30yr |
From the General Services Administration's monthly lease inventory: the rent the federal government actually pays, the square feet behind it, the dates, and the renewal options remaining. A fully serviced lease includes services and utilities, so it is not comparable to a net rent. This is one tenant, not the market. Federal space is often fitted for a specific agency and leased on government terms, so treat it as a real, checkable data point rather than an asking rent for the building.

Sale history

Prices are the consideration recorded in Washington, DC's public property records. Where a qualification code exists it is the assessor's judgement of whether a transfer was arm's length; transfers without one appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.

Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.
