3237-3239 Judah St, San Francisco, CA 94122

The two-unit residential building at 3237-3239 Judah Street in San Francisco's Outer Sunset neighborhood, currently owned by the Diana Rosa Wong Trust, has undergone several significant improvements since its construction in 1950. The property has seen substantial window upgrades over the years, with recent replacements in 2017 (seven windows and one door) and 2004 (ten windows), demonstrating ongoing maintenance and improvements to the building's thermal performance.

In 2009, both units received high-efficiency furnace replacements, marking an important upgrade to the building's HVAC system. More recently, the property has embraced renewable energy technology with the installation of two solar systems in 2019-2020, the first consisting of 12 modules with a total capacity of 4.32 kW, and the second with 8 modules rated at 2.88 kW, suggesting the owner is committed to sustainable energy solutions. The building's maintenance history shows attention to both structural and environmental improvements, though there have been some maintenance issues noted in the 311 calls.

These include a collapsed sidewalk incident in 2020 requiring utility vault repairs, and various street-related concerns such as garbage, graffiti, and sign defacement between 2018 and 2023. While these exterior issues have been resolved, they suggest ongoing attention to the building's surroundings is necessary. The property's recent improvements, particularly the solar installations, indicate a focus on modernizing systems and reducing environmental impact, while the documented window and HVAC upgrades demonstrate regular maintenance of core building systems.
