212 Frederick St, San Francisco, CA 94117

The two-unit, two-story multi-family residential building at 212 Frederick Street in the Haight Ashbury neighborhood, owned by David C & Inge Borgstedt Ne, was constructed in 1900 and has undergone several significant infrastructure improvements over the past two decades. Most notably, between late 2014 and early 2015, the building received comprehensive HVAC system upgrades including flexible ductwork replacement, furnace installation with new flue, and electrical supply work, totaling approximately $8,430 for the ductwork alone.

Earlier major work included a roof replacement with composition shingles in 2002, and a foundation retrofit in 2001 which was valued at $15,000, though this permit eventually expired. The property has experienced substantial parking enforcement issues in recent months, particularly from November 2024 through January 2025, with ten separate incidents of blocked driveways reported and various enforcement actions taken, including issued citations and towing requests.

The only other service-related incident in this period was a December 2024 report of loose garbage and debris, though this was determined to require no work. The building's recent maintenance history demonstrates attention to critical systems infrastructure, particularly HVAC improvements which were successfully completed, though the foundation retrofit permit from 2001 is noteworthy for its expired status despite being a significant structural improvement.
