489-491 Guerrero St, San Francisco, CA 94110

The property at 489-491 Guerrero Street is a two-story, three-unit multi-family residential building located in the Mission Dolores neighborhood, constructed in 1906 and currently owned by the John E Wai 1981 Living Trust. The building's most significant documented issues occurred in January 2010, when multiple housing code violations were filed, including problems with windows, water damage, mold/mildew, deteriorated siding, and lead paint concerns. These violations, which encompassed both interior surfaces and building sections, were officially abated by August 2012 following a director's hearing on May 6, 2010.

Earlier repair attempts were documented in 1986 with permits for sheetrock work, though one permit was cancelled. More recently, the property has experienced several infrastructure-related issues, with three sewer/water incidents reported on September 28, 2024, involving a flooding situation, sewage backup, and water leak from a main line. The building's immediate surroundings have shown continuing maintenance needs, including a collapsed sidewalk (reported October 2022) and recurring issues with garbage receptacle management (multiple incidents from 2021-2023).

While there were previous plans under consideration for establishing a small self-service restaurant at this address, these proposals are now listed as closed in the planning records. The property's recent history suggests ongoing challenges with both building systems and exterior maintenance, with particular attention needed to address recurring sewer-related issues as of 2024. The resolution of the 2010 housing violations demonstrates that significant interior maintenance issues were addressed, though no building permits for major renovations or repairs appear in the recent history.
