549 Corbett Ave, San Francisco, CA 94114

The 6-unit, 3-story apartment building at 549 Corbett Avenue in Twin Peaks, owned by MCCW LLC and constructed in 1957, has undergone several significant improvements and repairs over the past few decades. Most notably, the building completed a mandatory seismic retrofit in 2017 to address soft-story vulnerabilities, as well as a comprehensive furnace replacement project that same year.

In 2016, the property faced compliance issues regarding unauthorized work, including deck replacements and drainage modifications, which were subsequently addressed through proper permitting, including repairs to deck dry rot. Earlier maintenance includes a 2010 handrail installation to resolve a violation, and various infrastructure improvements such as roof replacement (1997), concrete garage floor replacement (1986), and fence repairs (1995). The building has a documented history of addressing safety and code compliance issues, including multiple building violations from 2002-2010 related to handrails, security viewers, and fire safety requirements, all of which were brought into compliance.

Recent 311 calls (2020-2023) primarily consist of routine street maintenance issues such as graffiti removal and general cleaning, though one call in 2018 regarding sewer issues was investigated and found to have no problems. The property has maintained active compliance with housing inspections, with the most recent routine inspection occurring in 2017, and has successfully completed all mandatory safety improvements, including the soft-story retrofit classified as Tier 3 with Certificate of Final Completion issued. The building's maintenance record shows regular attention to both building systems and safety requirements, though there have been some instances of work being performed without proper permits, which were subsequently addressed through appropriate channels.
