1307 Kansas St, San Francisco, CA 94107

The two-unit residential building at 1307 Kansas Street in Potrero Hill, owned by Jane K Hamataka, is a two-story flats and duplex structure built in 1923. The building's maintenance and permit history shows relatively minimal major interventions, with the most significant recent infrastructure update being completed in May 2022 when the building underwent a 5-inch house trap and lateral replacement, while an earlier vinyl siding installation from 1990 is now expired.

The property has experienced three documented fire incidents, though none resulted in civilian injuries: a system malfunction, a lock-in situation, and an unintentional fire classified as "other." The property has seen a notable volume of municipal service calls in 2024-2025, with the majority relating to street conditions and parking enforcement rather than issues directly affecting the building itself. These include multiple reports of abandoned furniture and electronics (August 2024), two instances of sidewalk parking (October 2024), and various street maintenance requests including graffiti removal and a bent traffic sign.

The most recent municipal service call relates to a paint shop request in January 2025. While these external issues have been generally resolved, they suggest the building is located in an area experiencing some neighborhood maintenance challenges, though these issues are primarily street-related rather than building-specific.
