UCSF continues expansion into Dogpatch

Updated: Jul 6, 2021

UCSF continues its expansion into the Dogpatch Historic District with the development of the 36,000 sq. ft. CalSteam property at 777 Minnesota Street


UCSF has now determined what they intend to do with their 777 Mariposa property (large full-block warehouse once housing CalSteam plumbing wholesale), bordered by Indiana, Minnesota, and the UCSF Tidelands Dormitory to the south.

In the 2015, the Dogpatch Community Task Force was formed to handle the negotiation of "cushioning". This was at term UCSF used for the payment of a one-time grant to the Dogpatch community in lieu of the lost tax and impact fee revenue that all other developers pay to make capital improvements and support amenities like Esprit Park, 22nd St. Caltrain Station, Staircase at 22nd up to Potrero and The Dogpatch Hub. (UCSF also took money from this pot for the traffic light at 18th and Minnesota, to the community's dismay).

Attached are documents from the DCTF effort-including a City Budget office tally of what we the community loses in supportive taxes and fees when a University takes up over 4 acres of property. For even more information, below is a great article about the amount of encroachment UCSF has made into the Dogpatch community, despite having an entire campus to develop.

Here is the 2016 Chronicle article that outlines the acquisition and the neighborhood's objection to further expansion:

Current Message from UCSF about their 777 Mariposa Street plans:

"Construction to renovate 777 Mariposa Street for use by Thermo Fisher Scientific Inc. is scheduled to begin the week of June 28, 2021. The building interior will be renovated, rooftop mechanical equipment installed, and the exterior of the building modified to include a new entrance on Mariposa Street. Construction is expected to continue through Summer 2022.

Construction activity is scheduled to begin with contractor mobilization and site set up. The adjacent sidewalks on Mariposa and Minnesota will remain open.

Interior demolition and preparation for renovation will be isolated inside the building and is not expected to be noisy. Materials will be removed via Indiana Street.

Work hours are:

Weekdays: 7 a.m. – 5 p.m. with noisy work after 8 a.m.

We apologize for any inconvenience this may cause.

Construction projects are dynamic, and activities often change. UCSF strives to share what we know with as much advance notice as possible.

Thermo Fisher Scientific, the world leader in serving science, and UCSF have formed a strategic alliance to accelerate the development and manufacturing of cell-based therapies. 777 Mariposa will serve as a state-of-the-art cell therapy development, manufacturing, and collaboration center operated by Thermo Fisher. The site will offer clinical and commercial cGMP cell therapy manufacturing services, along with associated technology development support, to UCSF and other partners.
