354 Crescent Ave, San Francisco, CA 94110

354 Crescent Avenue is a two-story, three-unit multi-family residential building constructed in 1900, currently owned by 354 Crescent Holdings LLC. The property has undergone several significant modifications and faced multiple compliance issues in recent years. Most notably, there are active complaints regarding an unauthorized ground floor unit, with reports filed in September 2023 and September 2024, suggesting the building may contain more units than legally permitted.

The building's electrical and plumbing systems received substantial updates in 2019, including a 200-amp electrical panel upgrade and complete rewiring to replace knob-and-tube wiring, though this work was temporarily halted by a notice of violation in April 2019 for exceeding the scope of approved permits. The property has seen various improvements, including reroofing in 2022, kitchen remodeling, and bathroom renovations on the second floor, along with ongoing efforts to legalize a ground-level unit as a JADU, with a permit filed in November 2023. The building's maintenance history includes some exterior work, such as a withdrawn permit for front stair railing replacement in 2023.

Recent infrastructure concerns have been documented through 311 calls, including reports of collapsed sidewalks and garbage issues, though these were primarily street-level concerns rather than directly related to the building's condition. The property experienced one tenant buyout in March 2019, totaling $29,814.52 for one tenant. While there have been various complaints and violations, many have been addressed or resolved, though the current status of the illegal unit situation remains active and under review. The building's utility systems appear to have received necessary modern updates, though the historical legacy systems were clearly problematic, as evidenced by the 2019 violations and subsequent upgrades.
