The League of American Bicyclists released the 2015 Bicycle Friendly Businesses list and two local "businesses" made the list: The Architect of the Capitol and Kevin H Posey, The Biking Realtor Coldwell Banker Residential of Alexandria. [Also A-1 Cycling in Manassas, but that's pretty far out]. All of these businesses are now bronze.
It's kind of odd to award the AOC a designation since the Capitol itself is somewhat not bicycle friendly, though that may be due to the Capitol Police or the Sergeant-At-Arms. For example, there still isn't a CaBi station anywhere on Capitol grounds, even though there were plans to add one near the Capitol South Metro as far back as 2012.
There is one at Penn and 3rd, but that's outside the Capitol grounds.
In addition, barriers erected after 9-11 have made the Capitol grounds less bike friendly, and many of those impacts have not been addressed.
