The property at 164-166 21st Avenue is a two-unit, two-story multi-family residential building constructed in 1921, currently owned by the Jerry Lou Revocable Living Trust. In 2012, the building underwent significant improvements totaling $45,000, including kitchen and bathroom remodels in both units, furnace replacements, window upgrades, and new flooring. This renovation work was accompanied by corresponding electrical and plumbing upgrades, including the installation of various modern appliances and fixtures.

During this period, there was a brief building complaint regarding unauthorized deck construction in March 2012, though this was resolved within four days. The building has seen several notable improvements since 2012, including the installation of a 3.84 kW solar panel system in 2017 and a smaller 1.416 kW system in 2012, demonstrating a commitment to sustainable energy. Recent maintenance and safety concerns have been minimal, though there was a roofing drainage issue reported in March 2019 that remains marked as not active in the system.

The property has experienced some periodic issues with driveway blocking, particularly in 2019-2022, with multiple citations issued for this infraction. Additionally, there was a reported incident of mold and water leaks in 2011, since which no similar complaints have been recorded. Of particular note, there was one documented gas leak incident (412 Gas leak) with no civilian injuries. The building's permit history suggests regular maintenance and upgrading of systems, with no major violations or safety concerns recorded in recent years.
