1000-1022 Filbert St, San Francisco, CA 94133

The 7-unit, 3-story multi-family residential building at 1000-1022 Filbert Street in Russian Hill is owned by Knight Family LLC and was constructed in 1912. The property has undergone significant improvements in recent years, most notably in 2020-2021, when two new accessory dwelling units (ADUs) were added (one in each building), and extensive renovations were completed including unit remodels, fire safety upgrades, and utility improvements. The building received a new fire sprinkler system, an upgraded 400-amp electrical service, new roofing, and multiple unit improvements such as bathroom additions, laundry facilities, and HVAC replacements.

A roof deck installation in 2021 triggered a building complaint about unauthorized work, though this was relatively quickly resolved. The property has a history of building code compliance issues that appear to have been addressed. In 2014, multiple violations were recorded, including problems with fire safety equipment, plumbing, electrical systems, and building maintenance, though all were abated by August 2014. Similar compliance concerns were noted in 2015 regarding unpermitted work and missing inspections, which were later resolved.

The building's systems have been significantly upgraded in recent years, with completed work including a new sprinkler monitoring system, furnace installations, plumbing updates, and electrical improvements. A Tier 4 soft-story retrofit was also completed, demonstrating compliance with seismic safety requirements. Recent 311 calls largely relate to street cleaning and parking issues, with one sewage backup incident reported and resolved in 2022. The building's most recent permit activity in early 2024 suggests continued maintenance and system updates are ongoing, particularly regarding plumbing systems.
