It could be many years until the city breaks ground on a planned eight-story affordable housing development at 101 Hyde St., where the Tenderloin's derelict post office resided until late this spring. But change is already underway at the corner of Golden Gate and Hyde.

Yesterday afternoon, Hoodline tipster Darwin B. spotted crews painting over the colorful hummingbird mural that's long graced the building's Hyde and Golden Gate facades.

By 4:30pm, the entire building was awash in black and orange paint, presumably a nod to tonight's Giants playoff appearance.

Per the development plans approved by the city this summer, Shorenstein Residential purchased the one-story building for roughly $12.5 million and gifted it to the Mayor's Office of Housing (MOH) to build 85 units of affordable housing—in return for the right to build a 100 percent market-rate development with 304 units at Market and Jones, which could break ground before year's end.

Shorenstein also agreed to hand over $5.5 million for the MOH to conduct pre-construction work, and $1 million for a nonprofit to re-activate the building in the interim. There's no word yet on when 101 Hyde will reopen to the public—in the form of a food hall, as the Chronicle has reported.
