442 Union St, San Francisco, CA 94133

The 5-unit, 2-story multi-family residential building at 442 Union Street in Telegraph Hill, built in 1907 and currently owned by Theodore Kroeber & Candace Cr, has undergone several significant improvements to enhance safety and maintain its structure over the years. Most notably, the building completed a mandatory soft-story retrofit in 2016 at a cost of $40,000, bringing it into compliance with seismic safety requirements under SFBC Chapter 34B.

The property has seen two major window replacement projects, first in 2005 (30 windows replaced with white vinyl) and again in 2010 (31 windows replaced with wood clad windows by Milgard). Historical records show a deck and residential remodeling project was completed in 1985. The building's maintenance history includes some concerning incidents, such as an unpermitted remodeling of the lobby and rear room reported in 2013, though this complaint was quickly abated.

The property has maintained regular inspections through Housing Inspection Services in 2002 and 2005, both of which were resolved without noted violations. More recently, there have been multiple instances of street cleaning issues reported via 311 calls between 2018 and 2024, primarily related to loose garbage and cleaning needs on the sidewalk areas around the building, though all these reports have been closed and resolved through proper channels. The most recent significant building permit activity includes street space permits issued in 2015, 2016, and 2019, with one of these related to a valid street space permit with good path of travel in 2019.
