270 11th Ave, San Francisco, CA 94118

The two-unit residential building at 270 11th Avenue in the Inner Richmond, owned by Lei Shu Ru, is a two-story flats and duplex structure constructed in 1906. The most significant recent work on the property occurred in 2009, when extensive renovations were undertaken including the conversion of an existing bedroom into a master bathroom, addition of a new master closet, installation of two new bathrooms, reconfiguration of storage rooms on the first floor, and important dryrot repairs to the rear staircase.

This comprehensive renovation was properly documented through building, plumbing, and electrical permits, with the electrical work totaling a substantial 200-amp service upgrade that included extensive new circuitry, lighting, and fan installations throughout the modified spaces. The building's maintenance record shows minimal issues over the past decade, with only one documented 311 call in October 2012 regarding loose garbage on the street or sidewalk, which was promptly resolved by the Department of Public Works.

Given the age of the building and the scope of the 2009 renovations, the property appears to have been well-maintained in recent years, with no recorded building code violations or safety concerns emerging from the available data. The previously completed structural and systems upgrades from 2009 suggest that the building has received significant modernization, particularly in terms of bathroom facilities and electrical infrastructure.
