500-504 Hickory St, San Francisco, CA 94102

The property at 500-504 Hickory Street is a two-story, multi-family residential building constructed in 1900 in Hayes Valley, currently owned by Nicholas W. Keyes. The building underwent significant modifications between 2014-2016, including adding a new dwelling unit to convert from R-3 to R-2 occupancy.

During this period, the property was fully equipped with a new NFPA 13 fire sprinkler system with 46 heads, completed window replacements in Unit 504, and various interior improvements including bathroom and kitchen renovations. While the sprinkler system installation initially triggered a complaint in 2015 about unpermitted work, this was ultimately resolved. Multiple permits were issued for plumbing work, including sewer line additions and water heater installations, though several permits from 2014 expired without final inspection. Recent activity in 2022-2023 has primarily involved parking-related issues outside the property, with multiple citations for vehicles blocking driveways and parking on sidewalks, though these are not directly related to the building's condition or maintenance.

The most recent building-related activity includes two garbage and debris cases from December 2024. A planning record indicates a proposed project for front wall modifications and parking improvements, though this appears to be informational and not directly linked to current permits or complaints. The building's permit history demonstrates significant investment in safety systems and modernization, though the presence of expired permits suggests some oversight in final inspection processes. The property has maintained compliance with major safety upgrades, particularly through the comprehensive fire sprinkler system installation, which has apparently been accepted despite the initial complaint.
