The property at 3332-3334 21st Street is a two-unit, two-story multi-family residential building constructed in 1900 and currently owned by Jeffrey A. and Joanna G. Sacks.

The building has undergone several significant maintenance and improvement projects over the years, with the most recent being a substantial $35,000 reroofing work permitted in June 2024. Historical records show regular maintenance of essential systems, including a water heater replacement in 2008, two electrical service upgrades (200-amp in 2004 and 100-amp in 2006), and various structural improvements in 1988 such as beam replacements and the removal of a column in the recreation room. Notably, there was an incident of an illegal conversion complaint in 1994 regarding occupancy exceeding legal limits, though this was resolved within two months.

Recent activity around the property has included multiple 311 calls in 2024 regarding street maintenance issues such as garbage and debris, including reports of human waste. There have been several tree-related incidents reported between 2020 and 2021, including damaged trees and landscaping issues that were subsequently resolved. The building's safety systems appear to be functioning properly, with only one minor fire department response recorded in relation to a carbon monoxide detector activation that turned out to be a false alarm with no CO detected. The property's maintenance record shows regular upkeep, with the most recent permits indicating ongoing investment in building maintenance and infrastructure.
