The footprint on the block
Permits were filed on 7 August 2026 for the office-to-housing conversion of 150 Hayes Street. Emerald Fund and SDG are jointly responsible for the application. The converted building would carry 104 apartments, one fewer than the first announcement.
The site occupies Hayes Street between Polk Street and Van Ness Avenue. Those two named streets end the block.
The structure dates to 1968. The application converts it and adds one story of 15,530 square feet. The existing footprint stays.
Two ends, one walk
A walking route that uses Hayes Street leaves the block at Polk Street or at Van Ness Avenue and rejoins Hayes beyond the site. A guide sets the direction from the block geometry and confirms it with the applicant in writing before the group departs.
No detour notice has been published for this address. State that limit to the client.
Record the confirmation in the trip file. The apartment count moved by one unit between the announcement and the filing, and a filed permit can change scope.
Coach staging
The record carries no contractor and no construction start. A coach operator cannot book a staging side from a filing.
Put three questions to Emerald Fund and SDG in one message: the staging side, the hours of work, and the notice period before any curb restriction.
One message covers the walking product too. A group that arrives by coach and continues on foot needs one answer for both.
City Hall on the route
The source places future residents one block from City Hall and two blocks from the Civic Center BART station.
An itinerary built on that measure holds a civic stop and a transit stop inside one short leg. A group that leaves Civic Center BART reaches the block on foot. A group that ends at City Hall ends one block away.
Publish the measure the source gives. A walk time in minutes is the operator's estimate, and the trip file labels it as one.
What the record leaves open
The filing gives no construction start, no completion date, no contractor, no architect and no cost. Unit sizes, tenure and rent level are unstated. So are ground-floor commercial space and any hotel component.
Each gap changes an itinerary. A ground-floor outlet would give a group a stop. A published start date would give the operator a season to route around.
The rest of the campus
150 Hayes Street was one of four properties around Van Ness Avenue and Hayes Street that formed the vacated California State Automobile Association campus. The other three are housing: 101 Polk Street, 150 Van Ness Avenue and 100 Van Ness Avenue.
The source calls 100 Van Ness the biggest office-to-housing conversion in the city's history. Emerald Fund developed all three.
The new housing shares amenities with 101 Polk Street, per J.K. Dineen in the San Francisco Chronicle as cited. That list is the existing fitness centre and a new co-working space.
Set a review date
The count moved once already. Give the guide briefing a review date and put an owner on the operations side.
