1135-1139 Guerrero St, San Francisco, CA 94110

The 6-unit multi-family residential building at 1135-1139 Guerrero St in Noe Valley, owned by Renka Prop LLC, has undergone several significant improvements and faced various challenges since its construction in 1906. Most notably, the building completed its mandatory soft-story retrofit in 2019 (Tier 3) at a cost of $68,000, which was necessary to improve structural safety. Recent developments include pending approvals for converting two first-floor units into ADUs, with associated improvements to add bedrooms, kitchens, and bathrooms, as indicated in permits filed in September 2022.

The property has experienced recurring maintenance issues requiring attention, particularly in 2018-2019 when multiple violations were documented, including blocked exits, heating system problems, and plumbing concerns. These issues were generally addressed through permits for water heater installations, duct work modifications, and other repairs totaling substantial costs. Recent electrical work included upgrading systems and installing new equipment, with the most recent notable work being the installation of a concrete-encased electrode in 2022.

The building's history also shows regular maintenance of common areas, though there have been occasional concerns about garbage collection and stairway cleaning, as noted in 2019 complaints. While there have been fire safety violations in past years related to alarm systems and exits, these have been addressed through various corrective actions. The property's management has generally responded to maintenance and safety issues as they arise, as evidenced by the completion of numerous permits and correction of violations.
