19-21 Liberty St, San Francisco, CA 94110

This two-unit residential building, located at 19-21 Liberty Street in Eureka Valley/Dolores Heights, is a 2-story flats and duplex structure built in 1900, currently owned by Salomon Ari & Yamamoto Yori. The building has undergone several significant improvements over the past decade, including a major foundation upgrade in 2016 that replaced unreinforced brick masonry with reinforced concrete at the east wall ($30,000), a comprehensive renovation in 2018 of unit 21 including kitchen and bathroom remodeling, window replacements, and floor refinishing ($20,000). Recent improvements include a completed roof replacement in 2022 ($7,000) and the installation of a solar panel system in the same year (10.27 kW with 26 panels).

However, there are currently unresolved construction issues stemming from 2022 involving unauthorized modifications to the rear deck and stair system for unit 21, which led to an active building violation notice. The violation involves several safety concerns, including the adjacent window requiring tempered glazing, improper water heater enclosure, and an unpermitted structural frame wall on the property line, with a director's hearing scheduled for February 2024. The property has a history of maintenance and improvements, including electrical upgrades such as the transition from overhead to underground service in 2004 (200 amp) and various plumbing modifications.

While the building has received numerous permits for repairs and renovations, the ongoing violation regarding the rear deck construction raises significant safety and compliance concerns. The surrounding area has experienced typical urban issues as documented in 311 calls, including tree maintenance needs, encampment reports, and street cleaning matters, though these are more reflective of neighborhood conditions rather than building-specific issues. Recent planning applications submitted for 21 Liberty Street propose rebuilding rear egress stairs to code and creating new spaces in the rear carriage house, indicating ongoing development considerations for the property.
