20-22 Santa Marina St, San Francisco, CA 94110

The property at 20-22 Santa Marina Street in Bernal Heights is a two-story, multi-family residential building constructed in 1900, containing three units and currently owned by Hsieh Chia-hui. The building has undergone significant work and improvements over recent years, including major renovation projects in 2019 that encompassed electrical upgrades, plumbing improvements, and interior remodeling of the main house. These improvements included the installation of three heaters, rewiring of kitchens and bathrooms, and various structural updates such as new exterior siding, windows, and insulation, with a total cost exceeding $20,000 in 2019 alone.

Recent activity has focused on addressing the rear deck and studio addition configuration between the two addresses. Most notably, in 2025, there were plans (currently in Triage status) to demolish the existing two-story rear yard deck, combine the two addresses, and create a one-story studio addition to replace the existing 20 Santa Marina structure, along with adding a bedroom to 22 Santa Marina. This followed a period of work through 2024 that included verifying building use as two dwelling units and addressing a historical Notice of Violation from 2002 related to unpermitted deck construction.

The 2002 violation, which highlighted safety concerns about an unpermitted 10-foot high deck, was formally abated in August 2024. The property has experienced several typical neighborhood issues documented through 311 calls, primarily regarding parking violations and one instance of graffiti, though these are not directly related to building conditions. The extensive permit and violation history suggests active management of the property with ongoing improvements and compliance efforts, particularly focused on resolving historical deck-related issues and upgrading building systems.
