983-989 Capp St, San Francisco, CA 94110

Located in San Francisco's Inner Mission district, 983-989 Capp Street is a historically significant 2-story, 4-unit multi-family residential building constructed in 1910 and currently owned by Capp Street Properties LLC. The property has undergone substantial recent development, most notably in 2019-2023, when three additional dwelling units (ADUs) were successfully added - two to the front building and one to the rear structure.

This expansion was accompanied by important safety upgrades, including a voluntary seismic soft-story retrofit completed in 2019, and comprehensive fire safety improvements including new sprinkler systems installed in 2022-2023 with associated water service upgrades costing over $16,000. The building's history includes several notable events between 2003 and 2005, when it faced multiple fire safety violations that were subsequently resolved by August 2003, including issues with fire extinguisher maintenance, combustible storage, and egress obstructions.

More recent improvements include a 400-amp electrical system upgrade in 2022 to support the additional units, and ongoing maintenance of various building systems including plumbing and electrical infrastructure. The property has experienced recent encampment-related issues in the surrounding area (2022), though these were external to the building itself and have since been resolved. All current building permits and inspections show "Complete" or "Issued" status, indicating that the most recent improvements have been properly permitted and approved.
