1335-1339 Oak St, San Francisco, CA 94117

The three-unit residential building at 1335-1339 Oak Street, located in the Haight Ashbury neighborhood, is a 1912 three-story flats and duplex structure owned by the Fuentes Kyskan Family Trust. The property has undergone several significant improvements in recent years, with the most substantial renovation occurring in 2016-2017, including a comprehensive upper flat remodel valued at $68,000 featuring kitchen and bathroom updates, new lighting, wall alterations, and heating unit replacements. During the same period, the building received energy-efficient upgrades with the installation of 10 windows on the front facade, meeting modern U-factor standards, and improvements to the electrical system including a 200-amp service upgrade.

Safety improvements were also implemented, including the installation of exhaust fans in bathrooms, new gas fireplace, and compliance with fire safety requirements such as handrail installation to meet building code requirements. The building's maintenance and upgrades demonstrate regular upkeep, with earlier work including a complete reroofing project in 2015. Historical records show that the building faced several code violations in September 2010 related to fire safety, gas utility requirements, and plumbing issues, but these were all resolved by November 2010 through appropriate corrective actions.

The property has been subject to routine housing inspections throughout its history, with all identified issues being addressed promptly. Recent external environment reports from 2024 indicate ongoing urban challenges in the surrounding area, including encampments and park rule violations, though these issues are part of the broader neighborhood context rather than building-specific concerns. The building's permit history shows consistent investment in maintenance and improvements, with particular attention paid to maintaining historical accuracy through the use of appropriate materials and design features.
