The 4-unit multi-family residential building at 3454-3458 18th Street in San Francisco's Inner Mission neighborhood is a 3-story TIC building constructed in 1910. The property has undergone several significant maintenance and improvement projects since 2005, including electrical upgrades such as the installation of photovoltaic panels in 2009 and substantial kitchen remodels in 2006-2015.

The most recent work, performed in 2016, involved bathroom renovations on the second floor including plumbing modifications and electrical work, with a documented cost of $15,000. Earlier improvements included the replacement of non-historic aluminum windows with wood windows featuring curved profiles in 2015, and substantial electrical system upgrades including the addition of three 60-amp subpanels. The building's maintenance record shows particular attention to safety and security, with a routine safety inspection conducted by Housing Inspection Services in 2015 and a resolution of several violations in 2000 related to sanitation and security requirements, all of which were abated by February 16, 2000.

A single fire-related incident was recorded in 2008 regarding blocked exits, but was determined to have no merit. The property has experienced ongoing exterior maintenance issues, as evidenced by multiple 311 calls throughout 2024 primarily related to graffiti on parking meters and street poles, which have all been resolved. An open issue remains regarding a sidewalk defect related to tree root lifting documented in September 2024.
