5268-5270 Mission St, San Francisco, CA 94112

The two-unit, two-story multi-family residential building at 5268 Mission Street, owned by Danilo & Marleny Posadas, was constructed in 1924 and has a mixed-use classification that includes street-level retail. The property has undergone several significant maintenance and improvement projects, including the installation of a solar panel system in 2014 consisting of 10 residential roof-mounted solar PV inverters with a total rating of 3.1 kW.

In 2000-2001, there was a notable enforcement issue when unauthorized construction of a two-story addition approximately 8' x 14' on the rear of the building led to a violation complaint that was eventually resolved through proper permitting and completion of repairs to address dry-rot on the deck at a cost of $1,500. Of particular concern are the recent and recurring sewer issues documented through 311 calls, with seven reported sewage backup incidents between 2021 and 2024, including multiple incidents from the 4-inch sewer vent.

The most recent occurrences were recorded in September 2024, when there were sewage discharge issues from both a manhole cover and a side sewer vent. Additionally, there were two reports of abandoned furniture on the property in August 2024 that required cleanup. The building has a history of being responsive to necessary repairs and upgrades, as evidenced by the solar panel installation and the resolution of the 2000-2001 construction violation, but the persistent sewer issues suggest an ongoing infrastructure challenge that has required multiple interventions by city utility services over several years.
