919-921 Cortland Ave, San Francisco, CA 94110

The two-unit, 1939 multi-family residential building at 919-921 Cortland Ave in Bernal Heights, owned by 919 Partners LLC, has undergone significant commercial and infrastructure changes, particularly related to its restaurant space. Originally a pizza restaurant, the property underwent extensive renovations in 2014-2015 to convert to a full-service family-style diner, including substantial kitchen equipment upgrades, plumbing work, electrical installations, and fire system improvements, with associated costs exceeding $150,000.

Notable infrastructure work included a complete sewer line replacement in 2014, for which the concrete slab was temporarily removed, and subsequent fire safety system installations. The building has experienced recurring sewer system issues, with documented sewage backup incidents from the side sewer vent in September 2024 and January 2025. These incidents, though recent, follow a pattern of sewer-related work at the property, including multiple permits for repairs and replacements between 2013-2014.

The property has also faced maintenance challenges in recent years, including graffiti incidents, a sidewalk defect resolution in 2020, and multiple shared space-related issues reported in 2023-2024. Two fire complaints related to shared spaces were filed in December 2022 and closed in January 2023, though they were deferred. The building's systems were previously upgraded in 2005 with a 200-amp service and underground conversion, indicating attention to infrastructure improvements when necessary.
