1456 9th Ave, San Francisco, CA 94122

The property at 1456 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-story, three-unit multi-family residential building constructed in 1906 and currently owned by Henry Klein. The building's history over the past two decades has been marked by several significant issues and code violations, particularly related to deck and stair improvements. Between 2006 and 2012, multiple permits and violations were associated with deck work, including an initial $20,000 project to replace rear deck and stairs at the top floor and address tile work at various levels.

These improvements led to several Notices of Violation, primarily concerning unpermitted modifications, improper drainage, and non-compliant railing construction. One particularly notable complaint in 2006 indicated that new framing created an unauthorized solid wall/railing structure, while subsequent violations in 2011 and 2012 were addressed through final inspections and permit completions. More recently, from 2020 to 2024, the building has experienced recurring issues primarily related to parking violations, with multiple complaints about vehicles parking on the sidewalk or in restricted areas.

There have been three noise-related complaints in the past three years, with the most recent being a report of amplified sound filed in September 2024. The building's electrical infrastructure was notably updated in 2003, when underground service feeds were installed for five meters (two residential and two commercial) as part of a city-mandated improvement. While the building's major deck-related compliance issues were resolved through permits and inspections in the early 2010s, recent complaints have mostly been related to parking and noise disturbances rather than structural or safety concerns.
