3677-3681 21st St, San Francisco, CA 94114

The three-unit residential building at 3677-3681 21st Street in the Eureka Valley/Dolores Heights neighborhood is a three-story flats and duplex structure built in 1900, currently owned by Raymond F Clark Properties. The property has undergone several significant improvements over the past two decades, with the most recent major renovation occurring in 2020 when eight windows in the front of the building were replaced with energy-efficient wooden clad casement windows at a cost of $60,000. The building has faced various maintenance challenges, particularly in the early 2000s, when multiple building violations were documented in 2002-2005 related to structural issues with stairs, decks, and safety concerns such as egress obstruction and security devices.

These violations were ultimately resolved, with most being abated by December 2005. The property's maintenance history shows attention to both structural integrity and systems upgrades, including a 2017 sewer repair, a 2014 catch basin installation, and plumbing work in 2008 for water line replacement. Several fire alarm incidents have been recorded over the years, though all were found to be false alarms or unintentional activations with no civilian injuries reported.

Recent maintenance records from 2024 indicate ongoing attention to exterior upkeep, with multiple service requests related to street lighting and sidewalk cleaning. The building's historical records reveal a pattern of addressing both routine maintenance and major repairs, with particular focus on addressing safety concerns and improving energy efficiency. The property has experienced periodic issues with exterior stairs and decks, as evidenced by multiple repair permits and violations, though these have been consistently addressed through proper channels. While the most recent violations and complaints were resolved over 13 years ago, and the building has received various infrastructure improvements, it's worth noting that the property has experienced some routine maintenance challenges as evidenced by multiple garbage and debris reports in recent months, though these appear to be primarily related to street-level issues rather than building-specific concerns.
