3630 20th St, San Francisco, CA 94110

The property at 3630 20th Street is a two-unit, one-story multi-family residential building located in the Mission Dolores neighborhood, owned by the Bailey Family Trust. Built in 1906, this flats and duplex structure has undergone several significant maintenance and improvement projects over the past two decades. Most notably, in 2015 the building received an $22,338 window replacement project, followed by a similar window upgrade in 2011 costing $5,451, with both installations meeting modern energy efficiency standards (U-valve ratings of <.32 and 0.30, respectively).

Earlier maintenance work included a roofing project from 1999, though this permit has since expired. The property has also required multiple street space permits from 2018, with four separate permits issued between July and October of that year, each with a nominal cost of $1.00. Recent incidents and maintenance records from 2022 to 2024 indicate some ongoing challenges with the property's immediate surroundings, particularly concerning street cleanliness and graffiti.

In late 2024, there were two documented instances of non-offensive graffiti on the residential building, though these were inspected and resulted in posted notices. The building's exterior environment has experienced recurring issues with loose garbage, as evidenced by multiple street cleaning calls between 2022 and 2024. A notable infrastructure issue occurred in June 2022 with a sewage backup involving a 4-inch sewer vent, though this was promptly addressed by Public Utilities Commission Sewer Operations. The property has maintained compliance with necessary permits and inspections, and while recent years have shown some external cleanliness challenges, these have generally been addressed through municipal services.
