413-417 Duncan St, San Francisco, CA 94131

The three-unit, three-story multi-family residential building at 413-417 Duncan Street in Noe Valley, owned by Catherine Daly and Greg Kelly, has undergone significant renovations since its construction in 1900. The most substantial work occurred between 2008-2013, including a major remodel and horizontal addition to the front building (July 2008), electrical rewiring (2013), and various unit-specific upgrades including kitchen and bathroom remodels in unit #5 (2011).

Of particular note is an ongoing concern regarding scaffolding, with active complaints filed in 2020 and 2023 about rusty, unsafe scaffolding that has remained in place for an extended period beyond the typical duration for such structures. These complaints highlight safety concerns about the long-term presence of scaffolding.

The building's maintenance history includes various plumbing and electrical upgrades, with heating system installations in 2009/2010 and multiple unit renovations between 2008-2021. A building violation from 2001 was filed regarding unpermitted remodeling of the ground floor, though this was abated within weeks. Recent 311 calls from 2022-2025 primarily relate to parking enforcement issues around the property, including multiple citations for vehicles blocking driveways or parking on sidewalks, along with some tree maintenance concerns that have been officially resolved.
