633 Oak St, San Francisco, CA 94117

The three-story, six-unit multi-family residential building at 633 Oak Street in Hayes Valley, built in 1908, has undergone several significant renovations and faced multiple safety-related issues in recent years. Most notably, in May 2023, the property filed for a mandatory fire alarm system installation to comply with San Francisco Fire Code requirements for non-sprinklered buildings, which is still in the filed status. The building experienced substantial work disruptions in early 2021 when multiple building violations were recorded, including issues with unauthorized renovation work in Unit 4, problems with mold/mildew, window repairs, and damaged ceilings, though these violations were abated by March 2022.

Between 2017 and 2021, several units (including Units 4, 5, and 6) underwent permitted renovations, including kitchen and bathroom updates, with associated plumbing and electrical work. The property has addressed its soft-story seismic safety requirements, with work completed and a Certificate of Final Completion issued. Multiple street space permits were issued between late 2019 and 2020, suggesting some exterior or public space-related work was conducted.

The building's maintenance history includes attention to various infrastructure elements, with recent 311 calls primarily related to street cleaning and sidewalk maintenance external to the building's direct management. Three separate Zoning Verification requests have been processed for the address between 2016 and 2018, indicating interest in confirming zoning-related details for the property. While the building's recent renovation activity suggests ongoing maintenance and upgrading efforts, the property has experienced periodic issues with building systems and weathered multiple violation processes, particularly during the 2021 period, before these were resolved through subsequent improvements and system upgrades.
