This 1941 Noe Valley duplex, owned by Sergio & Angela Fontana, has undergone several significant improvements and faced various challenges over recent years. Most notably, the building has experienced persistent maintenance issues, with a recent July 2024 complaint highlighting concerns about inadequate insulation leading to noise disturbances between units. Previous violations from 2018 included multiple safety and maintenance concerns that were subsequently addressed, such as plumbing issues, electrical code violations, and concerns about mold in the bathroom.

The property has seen regular upgrades, including a complete reroofing in 2020 (cost: $20,400), window replacements in 2019, and HVAC improvements with two furnace replacements and water heater installations. Security enhancements were implemented in 2018 with the installation of security cameras, though these initially triggered compliance issues due to lack of proper electrical permits. The building's systems have been more recently updated, including new washer and dryer installations in 2020, though the property continues to show some age-related wear with reports of cracked tiles, peeling paint, and various maintenance needs being reported through the years.

The duplex has a documented history of addressing both routine maintenance and more significant upgrades, including various plumbing improvements (notably a sewer line replacement in 2012), electrical corrections completed in 2018, and multiple building code compliance updates. While many past violations have been resolved, as evidenced by their "not active" status, the most recent tenant complaint regarding noise insulation from July 2024 suggests ongoing concerns about building envelope performance. The property has experienced multiple parking-related issues in the surrounding area, as documented in 311 calls, though these are unrelated to the building's internal conditions. Overall, the duplex has received regular maintenance and improvements over the years, with particular attention to compliance issues following the 2018 violations, though some building systems still show age-related characteristics typical of a structure built in 1941.
