Which floors show activity
Floors 5-7 show no business on record — 3 unbroken floors, the longest such stretch here. Also quiet: 2-3. That is where the public record shows nobody, in blocks — a place to start asking, not a listing.

Floors are read from suite numbers on Seattle / King County business records (suite 4900 → floor 49). A floor with no record is not necessarily vacant — it may be mechanical, occupied by the owner, or let to a business whose receipt carries no suite. Receipts also lag reality by months. This shows where the public record places businesses, not a rent roll or an availability report. A stretch of quiet floors is not contiguous space for rent — it is contiguous silence in the record, which is the closest thing the public record has to that question and worth exactly what it costs to check.
The building's own benchmarking filing
Energy performance
From the building's own filing under its city's benchmarking ordinance. An ENERGY STAR score of 75 or above means the building outperforms three quarters of comparable buildings nationally. It is a self-reported figure, verified by the city only to the extent the ordinance requires.

Sale history
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|

Prices are the consideration recorded in Seattle / King County'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.

Data provenance — public records only
- Seattle / King County — King County Assessor bulk extracts and Seattle open data. Washington law restricts commercial use of lists of individuals, so this metro is built without personal names by design: the county's name-stripped account file provides mailing addresses (portfolios group by mailing cluster, unnamed), sales show price and date but never buyer or seller, and tenants are business licence trade names.
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.
