1801 9th Ave, San Francisco, CA 94122

The two-unit residential building at 1801 9th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1923, currently owned by the Gracia Family Trust. The building has undergone several significant improvements over the past two decades, including foundation work in 2015 involving the voluntary replacement of 32 feet of concrete footing at a cost of $26,000, plumbing work for a gas houseline extension in 2010, and the installation of a Ufer ground electrical system in 2015.

A building complaint was filed in April 2020 regarding extensive cement coverage of side yards, with approximately 720 square feet covered on the north side, though this complaint is currently listed as not active. The most recent and concerning incident on record was a gas leak (natural gas or LPG) situation, though no civilian injuries were reported.

The property has experienced recurring issues with illegal parking, particularly sidewalk blocking and driveway obstructions, with multiple identical complaints documented throughout 2023-2024, though many of these were either not validated or unable to be responded to by parking enforcement. There were also some municipal service calls related to sidewalk maintenance, including a missing side sewer vent cover incident in September 2022 which was resolved, and street cleaning issues addressed by Recology in 2022 and 2020. The building's permit and violation history suggests ongoing maintenance and infrastructure upgrades, particularly regarding safety systems like gas lines and electrical grounding, though the nature and extent of the cement coverage issue reported in 2020 remains unclear from the available records.
