A $1 revision permit filed July 23 at 455 Market Street covers the replacement of the tower's firefighters smoke control panel. The original authorization it references, PA# 202412116639, exists as a sparse stub in the DBI Permit Tracking System but is otherwise absent from publicly accessible permit databases.

On July 23, San Francisco's Department of Building Inspection issued an over-the-counter alterations permit for 455 Market Street — permit 202607235462, estimated cost: one dollar. The work described: replace the existing fan and damper control panel in the tower's Fire Command Center with a new firefighters smoke control panel, integrated into the building's existing management system, with "all other work remaining." The parent permit identified in the description, PA# 202412116639, appears in DBI's Permit Tracking System with only a received date (as of January 29, 2025) and a plans revision number, but no address, description, or scope, and it does not appear in DataSF's Building Permits dataset or SF Planning's Property Information Map.

The $1 figure is a routine feature of how DBI logs revision permits. When a contractor amends a previously approved filing rather than opening a new one, the revision posts at nominal cost — the real dollar value and full scope already captured under the original authorization. That original is identified in the permit description as PA# 202412116639, a number whose format suggests a December 2024 filing date.

A search of DBI's Permit Tracking System for PA# 202412116639 reveals a record with a received date of January 29, 2025, and Plans Revision No. 1, but it lacks an address, description, or scope. DataSF's Building Permits dataset and SF Planning's Property Information Map, however, return nothing for this permit number. The adjacent permit number, 202412116638, also exists in DBI's system as an even sparser entry, with no received date. Fire-life-safety sub-permits can live in separate DBI categories that don't fully sync with what public datasets surface; DBI accepts formal records requests, capped at six per person per day, which is the direct path to the original file.

The pattern wasn't confined to one address. Permit 202607104842 — a $1 OTC alteration at 1 Market Street, issued July 10 — follows the same shape: a revision to a prior approval, nominal cost, the actual scope somewhere earlier in the chain. Two blocks east, 525 Market Street filed an alterations permit the same week, 202607205299, with a stated cost of $2,668,000 — that one reads plainly in the dataset.

455 Market's permit records existing and proposed use identically as office. The Fire Command Center is interior work; no scaffolding, no visible posting from the street. What's being swapped out is the panel a building crew would reach for if smoke started moving through the floors — the sort of infrastructure that won't announce itself from the sidewalk, whether the authorization behind it surfaces fully in a public database or not.
