251-253 San Carlos St, San Francisco, CA 94110

This two-unit, two-story multi-family residential building, located at 251-253 San Carlos Street in the Inner Mission neighborhood, was built in 1900 and is currently owned by Katie J. Moore and Juan Soria. The property has undergone significant renovations and improvements over the past several years, with the most substantial work occurring between 2017 and 2020.

In 2018, a major remodel valued at $345,000 was completed, including updates to the second floor (kitchen, bathroom, bedroom, windows) and conversion of first floor storage into living space. The building underwent important safety improvements in 2020 with the installation of 1-hour rated fire walls between units. Additional enhancements include a solar panel installation (3.465 kW with battery storage) completed in 2022, complete rewiring in late 2019, and comprehensive plumbing upgrades including radiant floor heating and repiping of the unit in 2019-2020. The property has also seen consistent window improvements, with multiple projects replacing and upgrading windows between 2010 and 2012.

The building's recent history shows attention to both modernization and sustainability, with substantial investments in building systems and safety measures. A significant horizontal addition was proposed in 2017 to excavate the basement/first floor, though its current status is listed as "Filed." The property has experienced recurring neighborhood maintenance issues as evidenced by multiple 311 calls in recent years, primarily related to garbage and debris on the street and sidewalk, though these appear to be external community issues rather than building-specific problems. The most recent building improvements and maintenance work were successfully completed in 2022, with proper closures of various plumbing and electrical permits, indicating good compliance with local regulations. The building's planning records show proper approvals for the units' configuration and modifications, including the addition of usable square footage and deck modifications, with no reported planning code complaints.
