4323 20th St, San Francisco, CA 94114

4323 20th Street is a 4-story, 12-unit multi-family residential building constructed in 1966, currently owned by the Farmas Family 2006 Trust and classified as an Apartment building with 5 to 14 units. The property has undergone several significant improvements over the years, most notably completing a mandatory soft-story retrofit in 2016 at a cost of $150,000, achieving compliance with San Francisco's seismic safety requirements.

The building's maintenance history shows attention to both structural and safety concerns, with multiple fire safety inspections and corrections made between 2013 and 2019 addressing issues with alarm systems, extinguishers, and exit maintenance. A substantial cluster of building violations was documented in September 2006, including problems with weatherproofing, fire escape ladders, guardrails, stairs, electrical outlets, and lead paint hazards, though all were abated by November 2006. Recent activity at the property includes a current active complaint filed in November 2022 regarding common areas, and multiple 311 calls in 2024 concerning garbage and debris issues, with several cases involving furniture removal from the vicinity.

A proposed development currently under review at the adjacent address (4327 20th St) seeks to replace a retaining wall/garden bed with a two-car garage and rooftop deck. The building's historical permits show various maintenance work, including window and patio door replacement in 1998 (permit expired) and reroofing in 1993 (permit expired), while street space permits were issued in 2016. The property's records indicate regular attention to fire safety systems, with most violations marked as "Condition Corrected," though the pattern of violations suggests a period of considerable maintenance challenges in the mid-2000s.
