829-833 Vallejo St, San Francisco, CA 94133

The 4-unit multi-family residential building at 829-833 Vallejo Street in North Beach, owned by Kenneth K W Szeto, is a three-story flats and duplex structure dating back to 1908. The building has undergone several significant improvements, most notably a comprehensive solar panel installation project in 2013 that included multiple phases with a total output capacity of 8.5 kW, along with electrical upgrades to support the system. Roofing work has been a recurring theme in the building's maintenance history, with major projects completed in 1998 and 2013, while a proposed window replacement in 2016 was cancelled.

The property experienced a rodent and insect infestation issue in April 2019 that warranted involvement from the Department of Public Health's Environmental Health division. The building's external environment has faced various challenges, including recurring issues with loose garbage in the vicinity, with multiple reports between 2019 and 2022. There was a documented incident of graffiti on the building in October 2016, which was addressed within days.

Parking-related complaints were recorded in 2018, and street cleaning concerns were raised in 2016 regarding an overflowing city garbage can. A smoke detector malfunction was recorded as a fire incident, though there were no civilian injuries reported. The property's maintenance record shows regular upkeep of essential systems, particularly focusing on sustainable energy improvements through the installation of solar panels, while also addressing basic residential infrastructure needs such as roofing and window maintenance.
