1925-1927 Lyon St, San Francisco, CA 94115

The property at 1925-1927 Lyon Street is a two-unit, two-story multi-family residential building constructed in 1923, currently owned by 1925-1927 Lyon Street LLC. The building has experienced several significant maintenance and code compliance issues over the past decades, with the most concerning period occurring between 2008-2010 when multiple violation notices were issued regarding unpermitted construction work, including electrical and plumbing installations, and hazardous conditions. These violations included improperly installed plumbing fixtures, a tankless water heater, electrical wiring work, and various appliances installed without permits.

While many of these violations were eventually addressed through permits and corrections, they indicate a period of substantial maintenance challenges. More recent history shows ongoing concerns with the property, including a mold complaint in 2017, and repeated issues with unpermitted short-term rentals, with violations recorded in 2011 and subsequently. The building's maintenance history shows some structural and systems upgrades, including completed kitchen and window renovations in the early 2000s, and a failed foundation upgrade and remodel project proposed in 2007 valued at $250,000.

The property has also been subject to various parking enforcement actions in recent years, primarily related to driveway blocking incidents recorded between 2019-2023. Most concerningly, there are two recent fire code violation notices from October 2021 and November 2024, though the specific nature of these violations requires further investigation. The building's historical records indicate a pattern of deferred maintenance and compliance issues, though many of these have been addressed through subsequent permits and corrections.
