1412 Lyon St, San Francisco, CA 94115

The 1412 Lyon Street property is a three-unit multi-family residential building located in Lower Pacific Heights, constructed in 1900 and currently owned by the Joelson Family 2009 Trust. The building has undergone several significant renovations and improvements over the past two decades, with the most recent major work being completed in 2006-2007, which included an interior remodel of the top unit (1412-C) with kitchen and living area updates, and electrical system improvements including the installation of new circuits and lighting.

The property has a history of addressing structural and safety concerns, with notable work completed in 2003-2004 focused on replacing rear stairs, decks, and addressing foundation issues, although this period was marked by some construction management challenges that resulted in building permit suspensions and violations being filed in March 2003 regarding unauthorized modifications to the deck configuration, new siding, doorway, and window installation work. These violations were ultimately abated by April 2004. The building's permit history shows consistent maintenance and upgrading of both interior and exterior elements, including window replacements in 2004 and various electrical system enhancements.

Several planning records indicate past proposals for additional modifications, including variances for front setback, minimum lot width, and rear yard requirements, though most of these have been marked as closed or withdrawn. The most recent building-related activity recorded was an abandoned vehicle complaint from November 2023, which was promptly resolved by city authorities. A routine housing inspection conducted in 2008 shows compliance with housing standards, and while there was an "illegal unit" complaint filed in 1996, this was resolved in 1997 and does not appear to be related to the current building configuration.
