Amending the Height of Buildings Act of 1910

, officially titled To amend the Act entitled An Act to regulate the height of buildings in the District of Columbia to clarify the rules of the District of Columbia regarding human occupancy of penthouses above the top story of the building upon which the penthouse is placed, is a United States Public Law that amends the Height of Buildings Act of 1910 in order to allow some penthouses to be built on the tops of buildings in District of Columbia.

Background
Current DC code allow things like air conditioners to be up to 18.6 feet taller than the roof of the building they are on. This bill would increase the height limit to 20 feet, tall enough to allow structures that humans can inhabit. The United States Congress started limiting the height of all buildings in DC in 1899. These height restrictions allow major monuments to be visible from a distance.

The change made by the bill was recommended by a study conducted by the National Capital Planning Commission and the D.C. Office of Planning.

The Congressional Budget Office (CBO) estimates that enacting H.R. 4192 would have no effect on the federal budget. The legislation would amend the Height of Buildings Act of 1910, which limits the height of buildings in District of Columbia The legislation would allow human occupancy of certain building penthouses that are currently limited to mechanical uses (such as climate control or elevators). Enacting the bill would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply.

H.R. 4192 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would impose no costs on state, local, or tribal governments.

Debate and discussion
D.C.'s delegate to Congress, Eleanor Holmes Norton (D) supported this bill, saying that "this bill is not a mandate directing the city to make any changes to penthouses or to its existing comprehensive plan or local zoning laws more generally."

Rep. Darrell Issa (R-CA) said that he favored the bill, acknowledging that "the District of Columbia has a unique visual requirement. We should not, cannot and will not obstruct the Mall and major parts of this historic city," but argued that this bill would not disrupt the skyline.

D.C. Mayor Vincent C. Gray was in favor of having greater options for building penthouses.
