1343-1345 Guerrero St, San Francisco, CA 94110

The property at 1343-1345 Guerrero Street is a three-story, two-unit multi-family residential building located in Noe Valley, constructed in 1884. The building has undergone significant structural and system improvements over the past decade, with the most substantial work occurring between 2017-2018 when foundation improvements were made, including lower slab modifications and replacement of deteriorated brick walls with new wood stud walls. Prior to this, in 2016, an unused chimney was removed and replaced with a skylight installation.

The property has seen comprehensive electrical system upgrades in 2011, including rewiring of both units with new lighting, appliance, and safety feature installations, as well as plumbing improvements during the same period, including the installation of tankless water heaters and new HVAC systems. The building's maintenance history shows attention to regulatory compliance, with work done to address findings from physical inspection reports in 2013, including electrical, plumbing, and general building improvements. A brief period of unauthorized remodeling work without permits was reported in 2010, though this violation was resolved within a few months.

More recently, there have been several maintenance-related 311 calls, primarily concerning street cleaning and tree management issues, though these are external to the building itself. The property's historical records also indicate a completed condo conversion process, transitioning both units to individual ownership status. The building's systems have been regularly updated and maintained, with particular attention paid to safety features such as smoke detectors and modern appliance installation throughout the years.
