309-311 Cornwall St, San Francisco, CA 94118

The property at 309-311 Cornwall St in the Inner Richmond is a 2-story multi-family residential building constructed in 1923, currently owned by the Woo Revocable Trust and containing 3 units. The building's maintenance history shows significant attention to infrastructure, with a complete sewer line replacement in January 2014 due to tree root damage, a street space permit issued in 2014, and a reroofing project completed in 2010 at a cost of $9,500.

An important safety-related installation of a fire sprinkler system in the basement was permitted in 1990, though that permit has since expired. Recent service calls indicate ongoing challenges with the property's immediate environment, particularly concerning sewer infrastructure, with a sewage back-up incident reported in December 2024. The building has experienced recurring issues with illegal parking and driveway blocking, with multiple enforcement actions recorded between 2022 and 2024, including citations and attempts at towing obstructive vehicles.

Street and sidewalk cleanliness has been a maintained focus, with several general cleaning interventions documented in 2022-2024, along with the resolution of a defaced parking sign in June 2023. A routine housing inspection was conducted in August 2003, though no active issues were noted from that inspection. The property's documented history reveals a pattern of addressing essential infrastructure needs while contending with ongoing neighborhood parking and street maintenance challenges.
