439-441 11th Ave, San Francisco, CA 94118

The two-unit residential building at 439-441 11th Avenue in San Francisco's Inner Richmond district is a two-story flats and duplex structure built in 1927, currently owned by Elizabeth Jensen and Pet Sung. The property has undergone several significant renovations in recent years, with the most recent work completed in July 2023 including a bathroom remodel costing approximately $35,732.

Prior improvements include substantial kitchen and bathroom renovations in 2019 ($39,783) where electrical systems were brought up to code, and earlier 2018 upgrades that included electrical work with new circuitry installation and the addition of dedicated circuits. The building's maintenance history shows attention to basic infrastructure, with multiple roofing projects documented in 1989 and 2005, though the 2005 permit is now expired. The property has a history of building violations from January 2002, when multiple issues were documented including mold/mildew on walls, plumbing and electrical violations, and security concerns, though all these violations were abated by February 25, 2002.

A recent complaint was filed in November 2024 regarding potentially unpermitted construction work involving cement removal and replacement in the basement/garage area, though this case has been marked as not active. Historical property issues have included reports of inadequate heat, lighting problems in common areas, and appliance concerns, though these appear to have been addressed through subsequent renovations and repairs. The building's more recent history shows consistent maintenance and upgrading of facilities, particularly focusing on modernizing bathrooms and kitchens while addressing electrical infrastructure needs.
