431-433 12th Ave, San Francisco, CA 94118

The two-unit residential building at 431-433 12th Avenue in San Francisco's Inner Richmond district is a 2-story flats and duplex structure built in 1922, currently owned by Lisa Wong. The property has undergone significant recent improvements, with substantial interior renovations completed in 2023 including work on the kitchen, dining room, living room, bedrooms, bathroom, and powder room, following an earlier bathroom and kitchen upgrade in late 2022 that involved tile, cabinets, and countertops improvements, with a reported cost of $70,000.

Historical records show earlier improvements from the late 1980s, including aluminum window installation in 1988 and termite repairs in 1989, though the latter permit expired. The building's maintenance history shows attention to infrastructure needs, particularly during the 2012 addressing of a lifted sidewalk defect, which was resolved through proper inspections and repairs.

Recent years have been marked by several parking-related incidents near the property, with multiple 311 calls regarding driveway blocking and abandoned vehicles between 2019 and 2024, though these were external matters not directly related to the building's condition or management. The most recent parking enforcement call in November 2024 was unable to locate the vehicle in question. The property has no recorded tenant buyouts, and the building's recent renovation history suggests ongoing investment in maintaining and updating the property for current standards.
