421-435 Buena Vista Ave, San Francisco, CA 94117

This 11-unit, single-story multi-family residential building located at 421-435 Buena Vista Avenue in the Buena Vista Park neighborhood was built in 1942 and has undergone several significant improvements and maintenance work over the past few years. Most notably, the building has been actively maintained with recent work including the installation of a mini-split system in 2025 (cost: $9,000), repair of a collapsed facade and awning due to dry rot in 2023 ($4,250), and multiple reroofing projects between 2019-2021 totaling over $60,000.

The property has also seen substantial system upgrades, including electrical improvements with the installation of solar PV, EV charger, and 100-amp service upgrade in 2021, along with plumbing upgrades including replacement of galvanized water lines with copper and installation of a tankless water heater in 2019. The building has a history of addressing various maintenance and compliance issues, including a complete soft-story retrofit for seismic safety, which is now complete.

Past violations from 2002 related to fire safety equipment and other building maintenance issues were resolved promptly, and there was a deck replacement compliance issue in 2004 that was also addressed. Recent complaints and service calls have primarily involved external issues such as graffiti removal and park-related concerns, rather than structural or safety problems with the building itself. The property has undergone several cosmetic and functional improvements over the years, including kitchen and bathroom remodels, window replacements, and the conversion of one bedroom into two compliant bedrooms with proper egress, demonstrating ongoing investment in maintaining and upgrading the building's systems and living spaces.
