Project Overview

This joint venture wants to build big at 530 Sansome Street in San Francisco. They’re talking about a total of roughly 649,500 square feet of space.

Here’s how it breaks down: about 230,100 square feet for a hotel, 342,000 square feet for offices, and 7,400 square feet for retail and restaurants. The hotel would take up floors four through fifteen, offering around 200 rooms.

Offices would fill floors 16 through 41, with amenities for employees on the 16th and 17th floors. At the bottom, a three-story podium would anchor the tower, using thick fluted metal panels for a sturdy look.

Skidmore, Owings & Merrill (SOM) is handling the design. They’re known for sleek, glassy towers, and this one’s no exception.

The tower will have a gentle taper and seven setbacks as it rises, which should soften its impact on the skyline and open up more views. Pastel-green metal panels will set off the exterior, giving it a fresh, modern vibe.

They’re also including a dedicated fire station right in the development, which city officials and nearby districts have noticed. It’s a nod to public safety that ties the project more closely to the neighborhood.

Executives say groundbreaking could happen as soon as this year, though there’s no official timeline yet. The partners call it an investment in San Francisco’s future, with Class-A office space, a high-end hotel, and a new firehouse for Jackson Square and downtown.

Design and amenities

41-story structure at 574 feet tall, with hotel and office space plus a mixed-use podium.
Hotel component on floors 4–15, about 200 rooms.
Office component from floors 16–41, with amenities on floors 16–17.
Retail and dining at the ground level, totaling ~7,400 square feet for locals and visitors alike.
Parking and cycling options include 74 car spaces and 104 bike stalls, which feels right for the Bay Area’s transit-minded crowd.
Iconic design by SOM, featuring a gentle taper, seven setbacks, and pastel-green metal panels on a solid three-story podium.

If you live in Marin County, this project’s bold look and luxe amenities might feel like a sign of the Bay Area bouncing back. It also highlights the never-ending need for good transit between San Francisco and North Bay spots like Mill Valley, Tiburon, San Rafael, and Novato.

Regional context and Marin impact

Even though the tower technically belongs to San Francisco, its influence definitely stretches into Marin County’s economic world. Downtown San Francisco’s resurgence has shaped jobs and commuting for years, pulling workers from Sausalito, Larkspur, Corte Madera, and honestly, plenty of other Marin towns.

A big-name hotel and new Class-A offices in Jackson Square could tighten business connections across the region. Marin-based companies that depend on SF headquarters might find it easier to host visiting professionals or send folks to Bay Area meetings and conferences.

If you’re a Marin resident who commutes to San Francisco or works with SF firms, you might notice some changes. Think shifts in housing demand, tweaks to transit priorities, and maybe even a new vibe in local hospitality.

Marin towns like San Rafael, Novato, Mill Valley, Sausalito, and Tiburon keep an eye on the Bay Area market. The 530 Sansome project really highlights how important sustainable design, good transit, and actual urban planning have become.

The timeline for all this? Still a bit up in the air. But the development fits into a bigger Bay Area trend where mixed-use projects are starting to shape how Marin communities think about growth, housing, and working together across the bay.
