451-457 Locust St, San Francisco, CA 94118

The 4-unit, 2-story multi-family residential building at 451-457 Locust Street in Presidio Heights, built in 1924 and currently owned by Locust Property LLC, has undergone significant renovations and faced several noteworthy issues over the past several years. Most recently, in 2023, the front staircase was replaced with concrete due to deterioration, following a pattern of stair-related work in 2022 which had been previously withdrawn. The building has seen substantial maintenance and upgrades, including a garage renovation in late 2022 with new lighting and an electrical panel, a comprehensive unit remodeling project in 2022 involving sheets rock, insulation, electrical, and plumbing work, and multiple kitchen and bathroom renovations between 2021-2022 with coordinated electrical panel upgrades and lighting installations.

The property has experienced several concerning incidents, most notably in early 2022 when unpermitted structural modifications to the garage resulted in a building violation related to support pillar removal, though this was eventually abated in September 2023. Other issues include complaints about electrical problems and construction work being performed outside permitted hours in 2021, as well as concerns about lead paint chips during unpermitted work in early 2022. The building has a history of maintenance needs, including water intrusion repairs in 2022 and multiple instances of flooding impacting a unit's entry door. While there have been several fire department responses, these have primarily been for false alarms or unintentional system activations, with no reported civilian injuries.

The property has recently experienced multiple reports of garbage overflow issues in early 2025, though these are more related to external waste management concerns rather than building conditions. The extensive permit history shows regular investment in building maintenance and upgrades, with particular focus on addressing structural, electrical, and plumbing improvements. The property has undergone significant modernization efforts, including the installation of new systems and infrastructure improvements to meet current codes and resident needs, though some past work was performed without proper permits, leading to violations that have since been addressed. The building's documented history suggests active management with a pattern of responding to both maintenance needs and compliance requirements, though some recent waste management issues have emerged as a recurring concern.
