The two-unit residential building at 3784-3786 20th Street in Mission Dolores, owned by Eli Merritt and Rosana Castri, is a two-story flats and duplex structure built in 1908. The property has undergone several significant renovations and repairs over the years, with major work concentrated around 2022. Of particular note is a fire incident that occurred in June 2022, which caused structural damage to the top floor of the upper unit, affecting ceilings and walls in both upper bedrooms, though the lower unit remained undamaged. This incident led to subsequent repairs including fireplace replacement, window work, and the installation of new metal chimney systems in late 2022, with the chimney work costing $15,000. The building has maintained regular updates to its systems, with a complete electrical upgrade including a new 150-amp service in 2006, and more recent gas line installations and tests in 2023. Plumbing infrastructure has also been addressed, with a complete sewer line and house trap replacement in 2013. Recent 311 calls have primarily concerned external issues such as graffiti and waste management around the property, with one notable sewage backup incident reported in 2021. The building's maintenance history shows regular upkeep and improvements, including a significant kitchen remodel for both units in 2001, rear dormer addition in 2012, and various safety-related upgrades to stairs and railings. The most recent electrical work in early 2023 involved updates to bedroom and living room systems, suggesting active maintenance of building infrastructure.

How 3784-3786 20Th St's risk score is calculated

What the score means for you
Grade A–B — Low risk
DBI rarely finds violations here. Strong maintenance history and a clean complaint record.
