322 Duncan St, San Francisco, CA 94131

322 Duncan Street is a two-story multi-family residential building located in Noe Valley, constructed in 1890 and currently owned by Duncan Partners LLC. The property underwent significant transformation in 2009-2011 when a major renovation project was carried out, involving the addition of a new unit and the construction of a third story to the existing structure, along with a new two-car garage at street level.

This substantial renovation, costing over $500,000, was completed in accordance with building permits and included associated plumbing and electrical work. While the project was mostly executed according to approved plans, there was a brief building complaint filed in September 2011 by a neighboring resident regarding potential light blockage, though this complaint was promptly abated within two days.

The building's maintenance history includes a complete reroofing in 1996 and installation of a door opener in 2012. In recent years, there have been minimal issues reported, with only three 311 calls since 2013: one regarding flooding/sewer issues in 2013, another about illegal postings in 2021, and a parking-related complaint in 2019 that was ultimately deemed invalid due to incomplete reporting information. The property's development history shows proper adherence to planning processes, with multiple records indicating the project's approval status, including CEQA clearance and various permit approvals for the third-story addition and unit conversion.
