1647-1649 Golden Gate Ave, San Francisco, CA 94115

The property at 1647-1649 Golden Gate Ave is a two-unit, two-story multi-family residential building located in the Alamo Square neighborhood, built in 1900 and currently owned by Ernst Southern Lvg Tr. The building has undergone several significant maintenance and improvement projects over the years, with the most recent being a substantial electrical upgrade in April 2024 to a 400-amp underground dual-meter service, demonstrating commitment to modernization.

Noteworthy improvements include a solar panel installation in 2020 (9.36 kW), a complete reroofing project in 2016 costing $53,780, and various repairs to address wood rot issues in the deck (2009) and bathroom (2003). Historical records indicate past structural concerns, with termite repairs to the rear stairs and decks in 1987 and earlier issues with dry rot and decayed stairs requiring attention.

The building's maintenance history shows regular attention to safety and infrastructure, though there was a notable incident in 1997 involving flooding between units and an extended power outage that required intervention from Housing Inspection Services. Recent 311 calls between 2023-2025 have primarily concerned external issues such as parking violations, garbage management, and sidewalk maintenance, with no building-specific complaints recorded in this period. The property appears to be maintained to current standards, with recent improvements focusing on sustainability (solar installation) and modernization (electrical upgrade), though there have been recurring issues with waste receptacle management in 2023 and several parking enforcement actions.
