1439-1441 Oak St, San Francisco, CA 94117

The 1439-1441 Oak Street property is a two-story, four-unit multi-family residential building located in the Haight Ashbury neighborhood, built in 1909 and currently owned by Linh Viet Nguyen. The building has undergone several significant renovations and repairs in recent years, including a major 2021 remodel costing $727,876 that involved substantial updates to multiple units, a voluntary seismic retrofit in 2022, and upcoming roof replacement work with an estimated cost of $27,000 scheduled for late 2024. However, the property has faced recurring maintenance and safety issues, particularly regarding water damage and structural concerns.

A notable problem was reported in July 2023 involving water intrusion from a shower causing damage to the garage ceiling, which may have affected the building's structural integrity. Multiple active violations from 2018 remain unresolved, including issues with floor coverings, walkways, fire safety, heating systems, and interior surfaces, with some violations being referred for legal action. Other concerns include heating system problems in early 2023, unauthorized plumbing work in 2019, and multiple reports of water damage and mold issues between 2018-2019.

The building has received permits for various infrastructure improvements, including a storm drain replacement (2019), furnace replacement (2023), and electrical upgrades. Recent developments include tenant buyouts in late 2023 (two tenants) and early 2024 (one tenant) for $100,000 each, suggesting potential plans for further building modifications or redevelopment. Planning records indicate a proposal to reinstate a fourth dwelling unit and install new fire-rated windows, with previous approvals for significant horizontal additions and ADU construction, though some of these plans were withdrawn. The building has a documented history of maintenance issues requiring attention, with particular attention needed to address the outstanding violations and recurring water-related problems.
