3660-3664 16th St, San Francisco, CA 94114

The property at 3660-3664 16th Street is a two-story multi-family residential building located in the Duboce Triangle neighborhood, containing three units and built in 1900. The building has undergone several significant renovations and faced various maintenance challenges over the past two decades. Most recently, in April 2024, major interior renovations were proposed for units 3660 (including new bathrooms, bedroom modifications, and kitchen work) and 3662 (including bathroom and kitchen renovations), though these permits are currently in "Filed" status.

The building has had recurring moisture-related issues, including documented mold problems in 2014 (affecting multiple units), and more recently in 2022 with water damage and mold identification work costing $2,000. The property has a history of structural and maintenance concerns, including the replacement of damaged shingles in 2022 (costing $27,000), repairs to the front stair landing in 2017, and replacement of the rear wood stairway in 2015 (both required to address safety concerns). Previous building violations from 2001 and 2004 related to lead paint concerns, stair repair requirements, and security issues were all resolved by March 2004.

There were also several maintenance-related complaints between 2014-2015, including reports of rot-damaged exterior elements, bathroom mold, and garage issues. While many historical violations have been addressed, the most recent developments suggest ongoing investment in unit improvements, with particular attention to addressing past water-related issues through current renovations. The property's age and history indicate regular maintenance challenges typical of historic buildings, though recent permitting activity shows continued investment in improvements.
