877-879 De Haro St, San Francisco, CA 94107

The three-unit multi-family residential building at 877-879 De Haro St in Potrero Hill, owned by Gerald J & Tricia A Probert, has undergone significant improvements and faced several maintenance challenges since its construction in 1925. Most recently, in 2023, the property received substantial upgrades with the installation of three solar photovoltaic systems, including a 5.525 kW system in July and a smaller 2.55 kW system in April, reflecting the owners' commitment to sustainable energy.

The building's recent maintenance history shows attention to basic upkeep, including a complete reroofing project in 2022 costing $8,000. The property has experienced several infrastructure issues over the years, with the most pressing current concerns being a collapsed sidewalk reported in June 2022 and tree roots lifting the sidewalk reported in January 2021, both of which remain open cases with the Department of Public Works. Historical records from the late 1990s show multiple renovation projects, including interior remodels, furnace installation, and deck construction, suggesting significant past investment in building improvements.

Planning records indicate previous attempts to legalize an existing second dwelling unit without necessary parking, and there was a resolved issue regarding illegal short-term rentals at 879 De Haro St. The building's utility infrastructure has received attention, with multiple electrical and plumbing permits issued in the 1990s, though some permits from that period expired. Recent infrastructure issues have included two separate streetlight problems in 2017 (one flickering and one burnt out) and a flooding incident related to street sewer systems.
