1475 Church St, San Francisco, CA 94131

The three-story, five-unit apartment building at 1475 Church Street in Noe Valley, constructed in 1926, has undergone several significant modifications and improvements over the past decade. Most notably, between 2018-2024, the property underwent substantial changes related to an accessory dwelling unit (ADU) project, including voluntary lateral strengthening work, seismic improvements, and a new sprinkler system installation. However, this ADU project has generated some ongoing compliance issues, with an active violation filed in July 2021 regarding an unauthorized second bedroom, improper sprinkler system installation, and missing plumbing permits for the kitchen and bathroom.

The building has also seen major infrastructure upgrades, including a 200-amp electrical service upgrade in 2019, new fire alarm system installation in 2021, and plumbing improvements including sewer pipe replacement in 2009. The property has experienced three fire-related incidents since 2021, though none involved civilian injuries or actual fires, including one carbon monoxide incident. Recent construction activity includes a September 2024 revision related to shear wall retention, following a pattern of modifications to correct previous construction issues.

Historical records show regular housing inspections and one tenant buyout in 2015. The building's maintenance history includes addressing various minor issues such as sidewalk defects and sign problems, with most recent service calls indicating routine municipal service needs rather than urgent building concerns. While many improvements have been made to the building's safety systems, including smoke detectors and fire sprinklers, the active violation regarding the ADU modifications remains a significant outstanding issue.
