984-988 Jackson St, San Francisco, CA 94133

The five-story multi-family residential building at 984-988 Jackson Street in Nob Hill, owned by Ivar Leif Hofvedt & Dolores, was constructed in 1907 and contains three residential units. The most significant recent improvement was completed in 2025, involving the installation of three separate radiant heating systems with domestic hot water production. This was preceded by electrical work in early 2025 for the penthouse addition, which expanded the top floor apartment with a new structure containing three bedrooms and two bathrooms, totaling 1,100 square feet.

The building has undergone substantial safety upgrades, including comprehensive fire safety system installations in 2008, featuring a full fire sprinkler system, underground fire line, and an addressable fire alarm system with multiple detectors and horns. The property has maintained active compliance with building codes and safety requirements, with recent plumbing work in 2025 adding roof drains and improving drainage systems. Historical records show the building underwent significant electrical upgrades between 2005-2007, including installation of a 240-amp service with four meters for all three units.

There were some concerns raised in 2016 regarding an unpermitted shed construction in the backyard area, though this complaint is now classified as not active. The building's maintenance record is generally positive, with most permit work being completed and inspected satisfactorily. The property has experienced minimal recent issues, with most 311 calls relating to sidewalk maintenance and street cleaning rather than building-specific problems. A single smoke-related incident was recorded with no civilian injuries reported.
