The three-unit, two-story multi-family residential building at 3736-3738 20th Street in Mission Dolores, constructed in 1907, has undergone several significant improvements and faced various maintenance challenges over its history. Most recently, in 2023 and 2024, the property saw electrical upgrades including the installation of a car charger and new lighting on the back stairs, along with completed plumbing work on the house trap and sewer lateral. A major renovation project in 2021-2022 included the construction of new decks on multiple floors, rebuilding of rear stairs, and lower-level modifications, demonstrating the owners' commitment to maintaining and upgrading the property.

The building has faced multiple safety-related issues in its history, particularly in the early 2000s. These included violations related to fire safety and egress requirements, such as obstructed exits and combustible storage issues, though all were resolved by February 2003. A complaint in 2011 about a removed fire escape ladder was addressed in 2012, and concerns about an allegedly illegal unit and access issues were investigated and resolved in 2012.

More recent maintenance history shows regular upkeep, including reroofing in 2016 and the installation of solar panels in the same year. The property has experienced occasional maintenance issues typical of older buildings, with 311 calls in recent years addressing matters like graffiti removal and rodent/insect infestation. The extensive permit and violation history shows a pattern of addressing safety concerns promptly when they arise, with all major violations from the early 2000s being resolved. Recent improvements focus on modernization and sustainability, including solar installation and electric vehicle charging infrastructure, suggesting active management and investment in the property's future.
