319-321 18th Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 319-321 18th Avenue in the Central Richmond neighborhood is a two-story structure built in 1966 and currently owned by 319 18th Avenue LLC. The property has undergone several significant maintenance and upgrade projects over the past three decades, with the most recent being three window replacements in 2012 using energy-efficient Simonton vinyl windows.

Prior to this, similar window upgrades were completed in 2011 and 2007, maintaining energy efficiency standards with U-values around 0.4 to 0.67. The building's exterior maintenance history includes siding replacement in 1999, though records indicate some confusion about the roofing work, with projects listed from 1993 and 1995 showing as expired permits.

The building's recent administrative history includes a 2022 Rent Board case that required unit count verification and fee payment assistance, while other documented incidents such as a parking complaint in 2019 and an environmental health complaint in 2013 appear to be unrelated to building conditions or management. The property's maintenance record demonstrates regular upkeep of windows and external features over the years, with no recorded incidents that would significantly impact resident safety or comfort. The windows replaced throughout the years show a consistent pattern of energy efficiency improvements, though the status of some earlier permits warrants verification of completion.
