136-138 San Carlos St, San Francisco, CA 94110

The property at 136-138 San Carlos Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission district. Built in 1909, the building has undergone several significant renovations and faced multiple regulatory challenges over the past decade. Most notably, between 2010-2013, the building experienced a period of unpermitted construction that resulted in multiple Notices of Violation, including unauthorized electrical and plumbing work, window replacements, deck renovations, and interior upgrades.

These violations were ultimately abated by June 2019. The building has undergone several major improvements since 2011, including a complete electrical system upgrade with new panels and meters, plumbing system improvements including new heaters and water service, and various interior and exterior renovations. Recent maintenance work includes reroofing in 2022 (cost: $16,000) and electrical upgrades in the laundry area the same year.

The building's maintenance history shows attention to major systems including plumbing, electrical, and HVAC, with most recent improvements focusing on building envelope and internal systems. The property's location in the Inner Mission has experienced numerous street cleaning and emergency sanitation calls in recent years, particularly in 2023-2024, though these external issues are typical for the neighborhood and not directly related to the building's condition or management. The building's historical challenges with code compliance and unpermitted work appear to have been resolved, with all major violations abated and subsequent improvements properly permitted.
