1339-1341 27th Ave, San Francisco, CA 94122

The two-unit residential building at 1339-1341 27th Avenue in the Central Sunset neighborhood, owned by Nancy E. Lewis, has undergone several significant upgrades and maintenance work since its construction in 1949. Most recently, in 2022, the building received a new furnace installation, following a previous HVAC upgrade in 2018.

The property has seen substantial interior improvements, including a comprehensive bathroom and kitchen remodel in 2018 ($50,000), window replacements in 2021, and multiple electrical upgrades corresponding to these renovations. Structural safety has been addressed with a voluntary garage reinforcement project in 2010 that included the installation of additional anchor bolts, clips, and plywood sheathing. The building's maintenance history shows attention to basic infrastructure, including reroofing work completed in 2011. While there was a period of concern in 2017 with fire complaints regarding hoarding and blocked exits, these were investigated and found to have no merit.

More recently, in 2021, there were incidents including a sewage backup and reports of garbage management issues, though these were resolved. The property has generally maintained active upkeep through various permits and improvements, suggesting regular maintenance by the owner. Automated systems like motion-sensor lighting and modern HVAC controls indicate a trend towards energy efficiency improvements. The building's permit history demonstrates a pattern of regular updates to both systems and aesthetics, with particular attention paid to safety features such as egress-compliant windows.
