18 Arleta Ave, San Francisco, CA 94134

The property at 18 Arleta Ave in Visitacion Valley is a two-unit, one-story multi-family residential building constructed in 1906, currently owned by the Liang/cheng Family Trust. The building's history reveals several significant events related to its maintenance and compliance with housing codes.

Most notably, in 2008, the property experienced a compliance issue when an unauthorized doorway was added to the front porch, resulting in a notice of violation (NOV) that was subsequently addressed through permitted work to remove and replace the wall, window, and door at a cost of $5,000. A more serious set of issues emerged in 1997, when multiple housing violations were reported including inadequate heating, roof leaks causing interior damage, plumbing issues, broken windows, and a malfunctioning garage door, though these were resolved by 1999 through various repairs including drainage and stair work, and garage improvements completed in 1999, as well as an approved reroofing project from 1998.

Recent activity around the property has primarily consisted of external maintenance matters, with numerous 311 calls recorded between October 2024 and January 2025, mostly related to graffiti on transit shelters, sidewalk debris, and one reported sidewalk defect. While these recent incidents are more related to neighborhood conditions than specific building issues, they indicate ongoing environmental maintenance needs in the immediate vicinity. The most recent building-related complaint dates back to 1997-1999, suggesting that no significant internal building violations or complaints have been recorded in the past 24+ years, which may indicate improved building maintenance standards in recent years, though this should be interpreted with caution considering the age of the building and its documented history.
