2701-2703 21st St, San Francisco, CA 94110

The property at 2701-2703 21st Street in San Francisco's Inner Mission neighborhood is a three-story, multi-family residential building constructed in 1900, currently owned by Robert A. Imhoff.

The building has undergone significant renovations and safety improvements over the past several years, including the installation of a comprehensive fire sprinkler system in 2020 (completed at a cost of $20,000) and the recent replacement of three furnaces with new flues in September 2023. The most recent permits indicate work on the garage structure, with a revision approved in October 2024 to change from two garage doors to a single door, following the original 2017 permit approval to accommodate a parking machine and increase spaces to three for the existing three-unit building.

Historical records show several compliance issues that have since been addressed, including past problems with water intrusion affecting neighboring properties (2012), and multiple violations in 2007 related to lead paint hazards, broken windows, and weatherproofing issues, all of which were abated. There were also concerns about construction safety in 2015-2017, including complaints about unauthorized razor wire installation and potentially dangerous construction practices, though these complaints are noted as "Not Active." The building's recent history (2018-2023) shows a pattern of completing various improvements to modernize the building and address safety requirements, including multiple plumbing and electrical upgrades in September 2023, installation of a sprinkler monitoring system, and finalization of several previously issued permits. The property has generated routine 311 calls primarily concerning street cleaning and sidewalk maintenance in 2023-2024, but these are typical for the area and not directly related to building conditions.
