3664-3666 18th St, San Francisco, CA 94110

The three-story multi-family residential building at 3664-3666 18th Street in Mission Dolores, owned by Raul & Denise Arriaza, was constructed in 1908 and contains 4 units. The property has experienced multiple significant issues over the past several decades, with the most serious incident occurring in September 2020 when the building sustained fire damage related to the electrical main panel on the ground floor, affecting wall studs and floor joists. Repairs included fire-damaged siding replacement and ceiling repairs, with electrical service upgrades completed simultaneously.

The building has a history of maintenance challenges, including a 2018 violation for failing to comply with soft story requirements, which was resolved in early 2020. In 2004-2006, the property underwent multiple repairs following a series of violations related to handrails, window frames, siding, lead paint hazards, and other building maintenance issues, all of which were eventually abated. More recent concerns include a broken front door security issue in 2022 and various 311 calls for street cleaning and maintenance matters, though these are more related to the building's exterior surroundings rather than the structure itself.

The building's maintenance history shows a pattern of addressing violations and completing necessary repairs, though some issues have recurred over time, such as door security problems. While many historical compliance issues have been resolved, the recent fire damage in 2020 and ongoing electrical-related complaints indicate that some systems may require continued monitoring. The property has also had periodic concerns about exterior maintenance, including peeling paint in 2011 and various exterior-related complaints, though most have been addressed through proper permits and repairs. The building's electrical service was upgraded to a 200-amp overhead system with multiple meters in 2020, suggesting modernization efforts have been made to improve infrastructure where necessary.
