1171-1175 De Haro St, San Francisco, CA 94107

The three-unit residential building at 1171-1175 De Haro St in Potrero Hill, owned by Sandra Coplon and built in 1906, has undergone several significant improvements and maintenance work over the last two decades. Most recently, in 2023, the property received substantial electrical upgrades including the installation of a solar PV system (5.655 kW) and relocation of the main electrical panel to improve safety and efficiency.

The building has maintained a regular schedule of necessary repairs, including a roofing project in 2021 costing $16,400, and significant structural work in 2018 addressing dry rot on entry stairs and concrete patio renovations. Historical records show attention to basic infrastructure maintenance, including window replacements in 2004 and house trap work in 2009. The property has experienced some maintenance challenges, particularly with sewer systems, having recorded two sewage backup incidents in September 2011, and service requests in 2018 related to sewer issues.

Security improvements were mandated in 2010 when entry door viewers were required, but this violation was promptly abated within one month. The building's maintenance history shows regular upkeep, with all recent permits and repairs completed to proper standards, though some past issues such as the 2018 repair work and the 2020 water leak required attention. The property's electrical system has received particular focus in recent years, with multiple permits related to panel relocation and solar installation, suggesting proactive modernization efforts by the ownership.
