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 |
|---|---|---|---|---|---|
| LDC00775 | 48,598 | $2,247,620 | $46.25 | Feb 2025 → Jan 2040 | — |
| LDC00776 | 8,872 | $395,314 | $44.56 | Feb 2025 → Jan 2040 | — |
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
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|

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.
