923-925 Filbert St, San Francisco, CA 94133

The two-unit residential building at 923-925 Filbert Street in Russian Hill, owned by the Howard W & Helen F Eng Trust, has undergone significant renovations and improvements since 2022, with the most recent work focusing on safety and energy efficiency. In 2024, permits were issued for voluntary lateral strengthening of the ground floor and crawl space, demonstrating a commitment to structural integrity.

The property has seen substantial window improvements, with multiple replacement projects totaling over $60,000, including recent permits in 2023-2025 for front window and general window replacements with improved energy efficiency ratings. A notable compliance issue arose in 2023 when unpermitted window installations triggered a building violation, though this was abated by December 2023 through proper legalization processes. The building has received comprehensive modernizations, including a significant kitchen remodel in 2022 ($50,000) with associated plumbing and electrical upgrades, installation of new central furnaces for both units, and significant insulation improvements to enhance energy efficiency.

The property has also had its electrical systems upgraded, with new subpanels installed in 2023. While there have been several parking-related complaints in the vicinity between 2019-2023, these primarily concerned public street parking issues rather than building-related concerns. The most recent building-related permits and improvements focus on energy efficiency and structural safety, indicating ongoing maintenance and upgrading of the property to meet modern standards.
