279-281 Collingwood St, San Francisco, CA 94114

The two-unit residential building at 279-281 Collingwood Street, owned by Happy Happy Homes LLC, is a two-story flats and duplex structure built in 1910 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant renovations over the past two decades, with the most recent major work occurring between 2015-2016, including kitchen and bathroom remodels in the main units and the removal of an illegal kitchen from the basement space to restore it as laundry.

These improvements encompassed ceiling work, lighting upgrades, and plumbing updates, with costs totaling approximately $34,500. The building's HVAC system was upgraded with furnace and duct replacements in 2016 and 2018, and there have been three separate roofing projects completed between 1995-1998, indicating regular maintenance of major systems. The property has experienced some neighborhood maintenance challenges, as evidenced by multiple 311 calls in recent years, including several reports of garbage and debris on or near the property between 2020-2024, though these were generally street-related issues rather than direct building concerns.

There was one instance of hazardous materials (glass) reported in March 2021, which was resolved. The building's renovation history shows proper attention to building code compliance, including an official process to remove an illegal kitchen, though there were some address correction issues in 2016 that required multiple permits to resolve. The most recent building-related activity appears to be from 2018, with no major permits or renovations on record since then, though this may simply reflect the completion of major work rather than any problems with the building itself.
