2835-2837 Octavia St, San Francisco, CA 94123

The three-unit residential building at 2835-2837 Octavia Street, located in San Francisco's Cow Hollow neighborhood, was constructed in 1922 and is currently undergoing significant modifications. The property has a documented history of construction work and violations that raise concerns about building safety and permit compliance. Most notably, there are **active violations** as of 2023 regarding unauthorized work beyond approved plans, including an **unauthorized third-level horizontal extension** and **mechanical work performed without permits**. Multiple complaints were filed in 2023 and 2024 alleging work was continuing despite posted work cessation notices, and concerns about construction height exceeding approved plans.

The building is also in the process of undergoing substantial safety improvements, including the installation of a **new fire sprinkler system** (completed in 2022) and electrical upgrades to 400-amp service with complete rewiring (2022). A **recent building complaint** from September 2024 describes the structure as having deteriorating construction and potential water intrusion issues, with reports of **black mold** and debris. The property has a history of addressing structural concerns, with foundation wall bolting work completed in 1995. Multiple 311 calls have been logged regarding parking violations and sidewalk cleaning issues near the property, though these are less relevant to building conditions.

Prior tenant buyout records show one unit received a buyout of $50,526.99 in 2019. The building's renovation history includes various permits for significant improvements, such as **mezzanine and roof deck modifications** (2023), kitchen and bathroom remodeling (2022), and an **expansive horizontal addition** (2018) that attempted to extend the building into the rear yard. The property has undergone multiple review processes, with several permits being issued, suspended, or otherwise modified throughout the construction period. The active construction violations, particularly regarding unauthorized height and extension modifications, appear to be the most pressing concerns based on the most recent complaints and enforcement actions.
