1283 40th Ave, San Francisco, CA 94122

The 4-unit, 2-story multi-family residential building at 1283 40th Avenue in the Outer Sunset, owned by Zeng Ty Ying & Chen Sung Yi, has been in operation since 1957 and has experienced several notable events over its history. The building underwent two routine inspections by Housing Inspection Services in 2000 and 2009, with the 2009 inspection revealing multiple violations including egress obstructions, security issues with rear door locks, and concerns regarding water heaters and exit signs. All of these violations were eventually abated by October 2009.

Two significant permit-related issues occurred in 2011, with unpermitted construction work and unauthorized conversion of the garage into a small business, though these complaints were quickly resolved. A routine inspection was conducted in 2018, and the building appears to have remained free of major violations since then. Recent activity around the property has primarily involved external issues, with multiple 311 calls between August 2024 and January 2025 regarding abandoned furniture and debris on the street, though these were not building-specific issues.

A sewer-related incident was reported and resolved in December 2024. The building's history shows a pattern of maintaining compliance with housing regulations after addressing past violations, with no fire-related civilian injuries recorded in the building's history. The most recent concerns have been primarily related to street cleaning and parking, rather than building safety or habitability issues.
