445-447 42nd Ave, San Francisco, CA 94121

The 445-447 42nd Avenue property in San Francisco's Outer Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1947, currently owned by the Arriola Family Trust. The building has experienced ongoing maintenance challenges in recent years, with particularly concerning water damage issues emerging in 2020, 2021, and most recently in April 2024, including reports of water intrusion, mold, leaking ceilings, and problems with windows and door thresholds. A significant maintenance history includes dry rot repairs completed in 2016 (costing $3,000) and the legalization of previously unpermitted spaces in 2004, which involved proper permitting for a garden/tool room and bathroom (cost: $5,000).

The property has faced multiple building violations, most notably in 2018 when there were issues with rat infestation, floor covering problems, and interior surface concerns, though these violations were subsequently abated in October 2018. Additional maintenance history shows some infrastructure attention, including reroofing work from 1990, though this permit is now expired. The building's recent history includes various 311 calls related to external issues, such as sewer discharge (resolved December 2024) and street lighting problems (resolved August 2024).

Several of the 311 calls from 2024 have been parking-related, including reported violations of driveway blocking and sidewalk parking. Of particular note is the ongoing pavement defect reported in August 2023, which remains open. The property has experienced recurring maintenance challenges, particularly regarding water-related issues, with multiple tenant complaints about inadequate repairs and persistent problems, suggesting ongoing difficulties in addressing basic building maintenance needs. The building's documented history shows a pattern of reactive rather than preventative maintenance, with multiple instances of tenants needing to file complaints to prompt repairs, particularly regarding water-related issues and interior surface concerns.
