249-251 Duncan St, San Francisco, CA 94131

The property at 249-251 Duncan Street is a two-unit, two-story multi-family residential building located in Noe Valley, built in 1900 and currently owned by Kundig Sylvia Revoc Tr. The building has undergone several significant improvements and maintenance work over the past few decades, with the most recent major building upgrades being the replacement of two windows in 2023 and the installation of a new furnace with metal ducts in 2022.

The property has seen consistent updates to its windows over the years, with window replacements recorded in 1996, 1995, and most recently in 2023. Other notable improvements include a sewer line replacement in 2015, kitchen remodeling in 2009 (including new cabinets, appliances, and a sliding door), and various interior upgrades such as plaster wall replacement with sheetrock in 1997. The building's maintenance history shows attention to structural integrity and resident comfort, including termite repairs in 1995, bathroom renovations in 1993, and a reroofing project in 1995.

However, there has been a significant pattern of driveway access issues recently, with ten recorded incidents of driveway blocking between August and December 2024, resulting in multiple citations being issued. While these parking enforcement actions indicate ongoing challenges with driveway access, they do not directly reflect on the building's internal conditions or management. The property appears to have received regular maintenance and upgrades over the years, with particular attention paid to energy efficiency improvements, as evidenced by the use of wood composite windows with low U-factors in recent updates.
