312-322 Baker St, San Francisco, CA 94117

The 12-unit, 3-story multi-family residential building at 312-322 Baker Street in Park North, owned by 312 Baker 14 LLC, has undergone significant upgrades and renovations since its construction in 1905. Most notably, the building completed a mandatory soft-story seismic retrofit (Tier 4) with a $140,000 investment in 2019, demonstrating structural improvement compliance. Recent safety enhancements include a $48,000 fire alarm system upgrade in 2023, installing wireless low-frequency sounders in sleeping areas and replacing existing systems in common areas.

Major unit renovations have occurred between 2018-2021, including comprehensive updates to multiple apartments (notably Units 320B and 314B), featuring kitchen and bathroom rehabilitations, additional bathrooms, and laundry facilities. These improvements were accompanied by necessary electrical and plumbing upgrades to bring systems up to current codes. The building has a documented history of addressing safety and maintenance issues, though recent concerns worth noting include routine inspections revealing past violations in 2019 related to water damage and flooding affecting interior surfaces.

While these violations were subsequently abated, they highlight historical maintenance challenges. The building's fire safety systems have experienced periodic compliance checks, with multiple fire extinguisher violations noted between 2016-2019, though all were corrected promptly. The property has maintained regular routine inspections by Housing Inspection Services since 2000, with the most recent occurring in August 2023 showing "Not Active" status. Recent 311 calls from 2025 suggest ongoing issues with external cleanliness and maintenance in the immediate vicinity, though these relate more to street-level conditions rather than building-specific concerns.
