Augrented Insights Report

The Dea Family Trust owns this two-unit, two-story multi-family residential building located at 505 21st Avenue in the Central Richmond neighborhood. Built in 1922, this flats and duplex-style property has undergone at least one documented improvement - the installation of aluminum windows in 1988, which was completed successfully.

The building's recent history shows a pattern of parking-related issues in the vicinity, particularly concerning vehicles parking on the sidewalk. Three separate incidents have been recorded between late 2019 and 2021, with two cases of sidewalk parking in late 2019 and late 2020, and one case of driveway blocking in April 2021.

The 2020 sidewalk parking incident resulted in a citation, while the 2019 incident was marked as "Unable to Locate" when enforcement officers responded. The most recent parking issue in April 2021 was resolved through officer intervention, suggesting that while these parking matters have required attention, they have generally been addressed through appropriate enforcement channels.
