1164-1166 Filbert St, San Francisco, CA 94109

The three-story multi-family residential building at 1164-1166 Filbert Street in Russian Hill, constructed in 1988, is a two-unit flats and duplex property currently owned by the Patricia Dinner Revocable Trust. The building has undergone several significant renovations and upgrades over the past three decades, with the most recent major improvements occurring between 2015-2018, including a substantial $500,000 interior remodel of the kitchen, laundry, and closet on the second level, installation of a solar power system with 12 PV modules, and a battery backup system with Tesla Powerwall technology. In 2016, the building underwent important safety upgrades, including reinforcement and replacement of the south balconies on level 3 with a 20-inch reduction in depth, and the removal and replacement of finishes in the powder room.

The property has maintained its systems through regular updates, including three furnace changes (one on each floor in 2011), fireplace installations (2021 and 2016), and various plumbing and electrical improvements. The building's maintenance history shows attention to both structural integrity and modernization, with earlier improvements including bathroom remodels (2002), kitchen/dining room renovations (1993), and various balcony-related enhancements. A noise complaint related to construction work was filed in 2016, though it is noted as not currently active.

The property has experienced recurring issues with driveway blocking, particularly in early 2020, resulting in multiple citations, though these appear to have been resolved. A sidewalk defect caused by tree roots was reported in 2019 and remains listed as open/accepted. The building's permitted modifications have generally received appropriate approvals, with notable projects including a deck installation and kitchen enlargement variance, though some proposals, such as building a 3-car garage at the front of the lot, were disapproved. The property's comprehensive renovation history suggests ongoing investment in maintenance and improvement, with particular emphasis on sustainability and modern conveniences in recent years.
