1140-1144 Leavenworth St, San Francisco, CA 94109

The property at 1140-1144 Leavenworth Street is a three-unit, three-story multi-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1911 and currently owned by Leung Kam Lun & Windy Ngan, this flats and duplex-style building has undergone significant recent renovations to improve tenant living conditions.

In late 2020 and early 2021, substantial upgrades were completed, including the replacement of old lath and plaster with sheetrock, kitchen and bathroom remodels, electrical system improvements on the third floor, and the addition of new lighting and outlets throughout. A new washer and dryer was also installed during this renovation period, with all work properly permitted and completed at a cost of approximately $49,000. The building's maintenance history shows attention to code compliance, with records indicating multiple routine housing inspections between 1999 and 2010, and the resolution of several previous violations from 2002 related to inadequate lighting in the rear passageway and lack of a utility shut-off tool, which were promptly abated within two weeks.

The property has maintained an active response to building upkeep and safety requirements, as demonstrated by the 1986 permits for code compliance work. Recent external environment issues near the property have been documented through multiple 311 calls between 2021 and 2024, primarily related to street cleaning and parking violations, though these incidents were generally addressed promptly by city services. The most recent building improvements and consistent resolution of past violations suggest a proactive management approach to building maintenance and tenant safety, with no active building violations currently on record.
