341-343 Lexington St, San Francisco, CA 94110

The property at 341-343 Lexington Street, a two-story multi-family residential building constructed in 1900, consists of four units and is currently owned by Peter Dana Porras. Recent significant improvements include substantial electrical upgrades in early 2024, with new wiring, removal of knob and tube systems, and installation of new sub-panels throughout all units. Plumbing infrastructure has been significantly updated, with permits issued in March 2024 for extensive work including kitchen and laundry facilities, and the removal of inactive water supply lines.

The building has undergone several important structural and safety improvements in recent years, including insulation work in early 2024, voluntary structural strengthening in 2022, and a complete roof replacement in 2014. The building's history reveals some concerning patterns of maintenance issues and code violations, particularly in the early 2000s. A cluster of violations was documented in late 2003, including problems with stairs, handrails, fire safety systems, and plumbing, though these were all abated by May 2004.

More recent complaints in 2014 and 2023 regarding unpermitted work and code compliance issues were also resolved. Of particular note are two complaints from 2015 concerning missing smoke alarms and various unit maintenance issues, which were addressed and closed. The property has maintained regular maintenance patterns in recent years, with multiple substantial improvements made to address older building systems. While some 311 calls regarding the property have been logged, mostly relating to street cleaning and maintenance matters, these do not appear to reflect significant building-specific issues.
