The three-unit residential building at 471-473 Frederick Street, owned by Jonathan L. Alba, is a three-story flats and duplex structure built in 1908 in the Parnassus/Ashbury Heights neighborhood. The property has undergone several significant renovations and improvements over the years, with the most recent major work being a furnace replacement in 2018 and bathroom renovations in Unit #473 completed in 2014.

Earlier improvements include window replacements in 2013 (61 windows), kitchen and bathroom remodels in 2014, and electrical system upgrades including a 60-amp subpanel installation. The building has experienced some maintenance challenges, particularly documented in a 2011 routine inspection that resulted in multiple active violations, including issues with guardrails, garbage receptacle placement, and various repair requirements. While many of these violations were previously addressed between 2003-2004, the 2011 inspection noted similar concerns regarding stairs, storage, and necessary permits.

The property has a history of 311 calls in 2024 primarily related to street cleaning and parking issues near the property, suggesting ongoing management of public space maintenance requirements. The building's permit history shows regular maintenance and improvements, though some plumbing and electrical permits from 2014-2016 expired, requiring renewals or amendments to complete the work. In 2020, there was an issued permit for street space usage, and the property has undergone various routine inspections by Housing Inspection Services over the years.
