3663-3665 19th St, San Francisco, CA 94110

The property at 3663-3665 19th Street is a two-story multi-family residential building constructed in 1908, currently owned by 3663 19th Avenue LLC, containing three units in the Mission Dolores neighborhood. The building has undergone significant renovations and improvements between 2020-2021, including a voluntary ground floor lateral upgrade with new perimeter foundation completed in 2020 at a cost of $76,000, and revisions to the rear cottage involving roof dormers, interior reconfigurations, and bathroom expansions completed in 2021.

These improvements included comprehensive updates to various systems, with electrical upgrades featuring new wiring, a 200-amp service, and four meters; plumbing improvements comprising multiple bathroom installations, kitchen updates, and HVAC systems; and structural enhancements such as foundation work and lateral stabilization to comply with modern building standards. The property has had its share of maintenance issues as documented through 311 calls, primarily relating to parking violations and occasional graffiti, though these are external to the building itself. Notably, a tenant buyout occurred in January 2020 involving five tenants with a compensation of $100,000.

The building's most recent construction-related activity appears to be from 2021, with all major permits showing completed or withdrawn statuses. The property has been actively maintained with regular updates to its infrastructure, though it's worth noting that certain proposed improvements, such as the addition of two ground floor accessory dwelling units in 2020, were withdrawn. The building's renovation history suggests a significant investment in modernizing the structure and improving its safety and habitability through foundation upgrades, electrical modernization, and comprehensive interior improvements across multiple levels.
