45-47 Dearborn St, San Francisco, CA 94110

The property at 45-47 Dearborn Street is a 2-story, 4-unit multi-family residential building constructed in 1911, currently owned by the E.S. Martin Family 2002 Revocable Trust. The building has undergone several significant renovations and repairs over the years, with the most recent major work being a roofing project in 2020 that included complete removal and replacement with new modified bitumen membrane at a cost of $4,700.

Of particular note, the property underwent a significant legal and structural transition in 2007 when an illegal unit, complete with kitchen and bath, was removed from the basement/garage level, along with associated dry rot repairs at the rear stairs, totaling $18,000 in permitted work. This followed multiple complaints and violations between 2002-2007 regarding unauthorized dwelling units, safety concerns, and building code violations. The building's maintenance history includes window replacements in 2003 (installing 9 new vinyl windows) and various repairs in response to housing violations.

In 2011, several safety and maintenance issues were addressed, including repairs to cracked exterior stair treads, peeling paint, gas utility shutoff requirements, and weatherproofing of siding. While there have been multiple 311 calls regarding the property's exterior conditions between 2021-2024, these primarily relate to street cleaning issues outside the building rather than building-specific problems. The most recent building-specific issue was a lead paint notification in 2011, which is no longer active. The property appears to have been maintained in compliance with building codes since the major 2007 renovation, with no recent building violations or complaints recorded.
