20 Broderick St, San Francisco, CA 94117

The 2-unit multi-family residential building at 20 Broderick Street in Buena Vista Park, owned by Thomas B & Monica P Casey F, has undergone several significant events since its construction in 1912. Most notably, the building experienced a serious balcony collapse in July 2021 (complaint #202180366), which prompted emergency responses and required subsequent remediation.

This incident led to multiple building violations for repairs needed to walls, ceilings, doors, and water damage, along with mold/mildew issues, though these were all abated by July 2022. The property has seen consistent maintenance and improvements, including balcony replacement in 2021 ($4,000), sewer line replacement in 2017, garage electrical work in 2023, and various historical updates such as window replacements (1997) and reroofing (1990).

A recent investigation in 2024 confirmed a potentially unauthorized short-term rental violation that resulted in an upheld appeal with pending penalties. The building's maintenance record shows attention to infrastructure, with street space permits obtained in 2000 and 2017, though there was an expired permit from 1990. The property has had recurring parking-related issues in the vicinity, with multiple 311 calls regarding sidewalk parking between 2020 and 2025, indicating ongoing challenges with parking enforcement in the area.
