457 Detroit St, San Francisco, CA 94112

The 4-unit, 2-story multi-family residential building at 457 Detroit St, currently owned by Bernal Heights Housing Corp and constructed in 1950, has experienced several significant maintenance and safety issues in recent years. The most pressing concerns include a major fire incident in 2021 that resulted in substantial damage to unit #407, requiring extensive repairs to bedrooms, kitchen, bathroom, and window replacement, along with subsequent mold issues and heater malfunctions reported throughout the building.

The common area stairs underwent reconstruction in 2023 following a complaint, including updates to meet current safety standards, while 2022 saw multiple infrastructure improvements including reroofing, fire damage repairs, and heating system upgrades. The building has a history of maintenance challenges, with plumbing issues including a sewer lateral replacement in 2018, and electrical concerns such as a transformer failure affecting the entire building in 2018.

Several fire safety violations were recorded in 2016-2017 regarding exit obstructions and fire extinguisher maintenance, though these were subsequently corrected. Recent complaints include non-conforming windows issues in 2022 and kitchen vent problems in 2023, with multiple 311 calls primarily related to parking violations recorded in late 2024. The property has undergone various improvements over the years, including window replacements, utility modifications, and several routine maintenance updates, though the frequency of complaints suggests ongoing tenant concerns about building conditions and maintenance responsiveness.
