20 De Montfort Ave, San Francisco, CA 94112

The two-unit residential building at 20 De Montfort Avenue in Ingleside, owned by Zhou Jian Fei, is a two-story flats and duplex structure built in 1925. The property underwent significant renovations in 2004-2007, including a major vertical addition in 2004 that added approximately 800 square feet and a new unit, followed by various improvements including kitchen and bathroom remodels on the second floor, new furnaces and water heaters, and comprehensive electrical work in 2007.

The building's infrastructure improvements during this period included new electrical systems with extensive lighting and appliance installations, and plumbing upgrades for two bathrooms and kitchens. In recent months, there have been multiple reports of garbage and debris issues near the property, with ten incidents documented between October 2024 and January 2025, primarily involving abandoned furniture and loose debris, though most of these cases were resolved promptly, with at least one noted as requiring no work.

From a safety perspective, the building experienced three minor fire-related incidents in the past, including a gas leak, a smoke scare, and a good intent call, none of which resulted in civilian injuries. A compliance action was recorded in 1985 to address inspection report requirements, and the most recent open case from January 2025 regarding garbage and debris remains in progress.
