475-477 30th Ave, San Francisco, CA 94121

The 475-477 30th Avenue property is a four-story, two-unit multi-family residential building constructed in 2003, owned by Angela N. Lam. The building was completed with modern safety features including a comprehensive fire sprinkler system installed throughout the structure at a cost of $12,000 in 2003, with subsequent backflow prevention work completed in 2017.

The original construction phase included the installation of essential systems such as new furnaces, water heaters, and electrical infrastructure including a 250-amp service panel. Several building improvements have been attempted over the years, including a cancelled 2019 permit for window replacement and previously expired permits for various interior modifications in 2002-2003, such as partitioning a playroom and exercise room. The property has experienced periodic maintenance and environmental issues typical of urban settings, including multiple noise complaints related to amplified sound in 2020, though these were summarized as informational reports.

Recent municipal service interactions include closed cases for garbage-related issues in 2024, with previous incidents of litter and street cleaning matters recorded in 2009-2010. The building's facade and window maintenance appears to have been addressed through planning records, with documentation showing repairs to leaks, window replacement, and siding work completed in accordance with 2019 specifications. While there have been various service calls to the address, they primarily reflect routine urban maintenance concerns rather than building-specific issues, and no significant safety or regulatory violations have been recorded.
