134-136 19th Ave, San Francisco, CA 94121

The two-unit residential building located at 134-136 19th Avenue in the Lake-Presidio neighborhood is a two-story flats and duplex structure built in 1922, currently owned by House Trust. The property has undergone several significant improvements over the years, with the most recent major upgrade occurring in October 2022, when the electrical system was modernized with the installation of new 200-amp meters and subpanels.

In 2021, there were preparations for new playground construction in the area, as indicated by pre-construction meetings for recreation equipment installation. The building faced a notable structural issue in late 2003 when a dangerous retaining wall failure was reported, leaning towards an adjacent property and prompting building violations and abatement proceedings. This issue was resolved by February 2004 following the proper permitting and completion of retaining wall replacement work costing $3,000.

Other improvements include vinyl window installations in 1996 and vinyl siding improvements in 2005. Recent maintenance records from 2023-2024 indicate various routine urban maintenance matters in the vicinity, such as graffiti removal, structural maintenance, and cleaning operations, all of which have been resolved. The property's historical permit records show regular upkeep and infrastructure upgrades consistent with maintaining a duplex of its age, and there have been no active building violations in recent years.
