3218-3220 17th St, San Francisco, CA 94110

The two-unit residential building at 3218-3220 17th Street in the Inner Mission, constructed in 1908 and currently owned by Adam Gelling, has undergone significant modifications over the years, with the most recent being the installation of a 13-d fire sprinkler system in 2024, which is currently being implemented with a cost of approximately $32,877. The building has experienced several major renovation phases, including substantial bathroom and kitchen remodeling work in 2005-2006 (totaling over $95,000), garage improvements including fire code upgrades in 2009, and a noteworthy attempt at a condo conversion in 2013 that addressed historical building lines and added non-load bearing walls and a bathroom to the first floor open space behind the garage (costing $40,000).

Infrastructure improvements include a new 200-amp electrical service installation in 2003, water heater replacements including the most recent installation in August 2023, and various plumbing and electrical upgrades throughout the building's history. The property has maintained a relatively active permit history, with most recent work focusing on safety upgrades such as the fire sprinkler system installation.

The building's external environment has experienced various maintenance challenges in 2024, including multiple reports of graffiti and sidewalk cleanliness issues, though these have been addressed promptly by city services. A construction-related sidewalk blockage complaint from 2000 was resolved within two days. The current permit status indicates ongoing safety improvements, with a recommencement of previously approved work scheduled for 2025 (valued at $20,000), demonstrating continued investment in the building's infrastructure and compliance with safety standards.
