1219-1221 3rd Ave, San Francisco, CA 94122

The two-unit residential building at 1219-1221 3rd Avenue in San Francisco's Inner Sunset neighborhood, constructed in 1908, has undergone several significant maintenance and improvement projects over the past decade and a half. Most notably, in June 2024, the property completed a sewer line replacement project extending from the building's foundation to the house trap, marking the most recent major infrastructure upgrade.

The building received a comprehensive reroofing in December 2008, costing approximately $21,310, and the installation of a solar power system that same year, consisting of 14 roof-mounted PV modules with a total capacity of 2.9 kW. Prior to these improvements, in October 2010, there was temporary street space usage for scaffolding, though the specific nature of this work is not detailed in the records.

The property's maintenance history shows attention to essential systems, with the sewer line replacement indicating proactive infrastructure upkeep, though it's worth noting this represents the most recent significant plumbing work on record as of October 2023. The building's documented improvements suggest regular maintenance and upgrades to both the roofing and electrical systems, with the solar installation representing an environmentally-friendly modernization of the property. The ownership of the building is registered to Robert C Gardner and Martha R, though no additional details about the owners' specific involvement in these improvements are provided in the records.
