Spear Tower's 6th Floor Gets $8M Office Buildout Permit

Spear Tower at One Market Plaza, also addressed as 55 Spear St, drew a $7,997,440 permit for a full-floor office buildout on its 6th floor, filed with San Francisco’s Department of Building Inspection on Oct. 23, 2026.

The filing, permit 202610239807, covers new open offices, meeting rooms and break rooms. Structural work is limited to anchoring phone booths and partial-height walls. It is filed under parcel 3713/007 as an over-the-counter alterations permit, and its status is listed as filed.

Why it matters

An $8 million spend on a single floor is a concrete bet on occupied office space in the Financial District, not a vacancy-rate estimate. For contractors and interiors firms, it is a full-floor job in one of the city’s marquee towers. For brokers, it is a sign that money is still going into finished floors at One Market Plaza.

The numbers

The permit lands four months after Willkie Farr & Gallagher announced a 12-year lease for about 35,000 square feet at Spear Tower, according to the firm’s June 30, 2026 release. That lease starts Feb. 1, 2027. The release names Elecor Properties as the building’s owner.

The permit does not say whether the 6th floor is Willkie’s space, another tenant’s, or a spec suite. DBI permit records carry no occupant field, so the work is logged to the building rather than to a named company.

What’s next

Work on a filed permit cannot pass key stages until DBI signs off on inspections. Whether the 6th floor belongs to a named occupant should show up in the permit’s contractor and inspection history on DBI’s tracking site, or in a lease announcement from the building’s owner or a tenant.
