Initial analysis

The property at 609-613 Fell Street in Hayes Valley is a two-story multi-family residential building containing three units, constructed in 1875 and currently owned by Sammy Lai and Lena Choy. The building has undergone several significant maintenance and compliance issues over the years, with the most recent substantial work being the $75,000 permeation grouting project initiated in 2019. In 2017-2018, the property faced serious compliance challenges related to unpermitted construction work in the rear yard, which involved concrete and wood retaining walls with fencing systems between 6 to 11 feet high. This resulted in multiple housing code violations including concerns about fire safety, egress obstruction, and general maintenance. The violation case was eventually closed in March 2018 after the owners completed required repairs and complied with a $10,000 notice of violation to address fence repair and parking area concrete replacement.

The building has a history of various maintenance and safety issues, particularly in the 2008-2010 period when multiple violations were recorded concerning interior maintenance, security, heating systems, and plumbing. Recent activity includes a routine safety inspection in 2022 (currently active) and there have been several 311 calls regarding the property, most recently in 2024 for excessive noise and a water leak. The property's maintenance history shows a pattern of addressing required repairs, though these have often followed code violations or complaints. The building's permit history indicates ongoing efforts to maintain and improve the property, with the most recent significant work being the permeation grouting project intended to address potential structural or foundation concerns. The property has also had various 311 calls regarding street conditions, illegal postings, and waste removal in the vicinity, suggesting ongoing attention to exterior maintenance and neighborhood concerns.
