4165-4167 20th St, San Francisco, CA 94114

The property at 4165-4167 20th Street is a 3-unit, 2-story multi-family residential building constructed in 1902 and currently owned by Morning Dew Properties LLC. The building has experienced several significant maintenance and safety issues over its history, with the most notable cluster of violations occurring in 2010 when multiple notices were issued and subsequently abated in May 2010. These violations included problems with interior surfaces such as water damage and damaged ceilings, security issues related to self-closing doors, fire safety concerns regarding flammable storage and missing fire extinguishers, and structural problems with handrails and a rear deck.

Earlier, in 2009, there was a concerning complaint about an allegedly illegal unit addition, unauthorized construction of back stairs, and general maintenance issues, though this was marked as not active by September 2009. The building has undergone several permitted improvements over the years, including a significant repair of fire damage in 1984, followed by various renovations including garage conversion attempts (which were ultimately cancelled), horizontal lightwell extension, and interior basement finish work in the mid-1980s. More recent maintenance work was performed in 2009 to address back stairs and deck issues, including railings and loose boards, though this was not directly related to the earlier violations.

While there have been numerous 311 calls in the area, particularly regarding parking violations and driveway blockages between 2021 and 2024, these are external issues not directly related to the building's internal conditions. The most recent parking enforcement actions occurred in late 2023, though all were closed as invalid due to incomplete reporting information. The building's violation record, while significant during the 2009-2010 period, shows no active violations since May 2010, suggesting that past issues have been addressed, though the age of the building and its history of various maintenance concerns warrant attention to ongoing upkeep needs.
