172 Landers St, San Francisco, CA 94114

The two-unit residential building at 172 Landers Street in Mission Dolores, owned by Jennifer Lachman, is a two-story flats and duplex structure built in 1900. The property has undergone several significant improvements over the years, including a complete reroofing in 1997 and replacement of plaster with sheetrock in the same year.

Currently, there are two major proposed construction projects under review that would significantly update the building, including exterior additions to both units, new rear decks and stairs, window replacements, skylights installation, new front entry steps and gate, as well as substantial interior remodeling of both units, featuring kitchen renovations and the addition of new rooms and facilities. The building's record includes some concerning historical issues, such as an active building complaint from 1994 regarding unauthorized changes to construction plans that affected ventilation and stair access, though this appears to be an isolated incident from nearly three decades ago. More recently, in December 2020, there was a fire complaint about blocked exits, which was promptly corrected within a week.

The property has experienced several maintenance and public space issues in the surrounding area, as evidenced by multiple 311 calls between 2023 and 2025, including incidents of human waste, debris, and various street cleaning matters. Two notable concerns involved blocked driveways by vehicles in July 2023, though both were resolved through parking enforcement. The most recent 311 call, from January 2025, reports the presence of graffiti, which remains unresolved as of now.
