But the limits allow for mechanical equipment rooms and non-habitable enclosures on many rooftops, which can increase the maximum by up to 18.5 feet. In his conversations with Issa, Gray has proposed allowing that extra space to be used as “living space.”
“It wouldn’t actually raise the height limit but could add a floor to a lot of buildings, which could substantially grow the population as well as the tax income of the city,” Gray said.
The mayor’s stance will likely prompt a backlash from some civic groups and preservationists, who have long sought to protect city views.
“We hold these national monuments as a treasure to be viewed and enjoyed and respected by people from all over the world and, for that reason, the current height limitations ought to be maintained. Period,” said William P. Lightfoot, a former D.C. Council member. “One story will block somebody’s view, and that is wrong.”
But as the District’s healthy real estate market continues to heat up, land is becoming scare, pushing development farther east along New York Avenue and into once-residential neighborhoods.
After the CityCenterDC mixed-use project near Chinatown and the new convention center hotel are completed over the next two years, there will be no additional buildable land in the core of downtown, according to the Downtown Business Improvement District.
With some federal restrictions likely to remain in place and city planners adamant they, too, care about preserving the sight-lines to the monuments, few expect that congressional action to loosen the rules would lead to the District turning into Manhattan.
“The Washington Monument is 550 feet high; whether a building is 130 feet or 140 feet probably is not going to make much of a difference,” said Eric Colbert, an architect with six projects on 14th Street NW, an area he predicts will be built out in two to three years.
Instead of vast changes to building heights, architects and builders said, tweaking the restrictions would free up a bit more space to allow them to experiment with design. In the suburbs, for example, most buildings are constructed with at least 9-foot ceilings but they are kept to about 8.5 feet in the District, said Shalom Baranes, an architect whose firm is working on the CityCenter DC project.
“If you raise the limits . . . what you would see is buildings getting just a little thinner as they go up,” Baranes said. “You would get a little bit more light and a little bit more space between them.”
If the city would also boost density rules, Baranes said about 100 office workers could be added to each additional floor. Residential buildings could house up to 40 additional residents per floor, he said.
The added population combined with higher ceilings could be a boon for city efforts to entice more retail stores to downtown, said Tom Wilbur, a vice president at Akridge development company.
Noting there are 20-story buildings in Rosslyn and Crystal City, Issa questioned why taller buildings are not allowed near New York Avenue NE or as part of the redevelopment of the campus of St. Elizabeths Hospital in Southeast — a change that could cause property values to skyrocket.
“We have an architectural interest in the nation’s capital, but it’s a pretty small area that we are really interested in,” said Issa, referring to Congress. “When you get to the edges of the city, you have to ask yourself: What harm would it be if those buildings were taller?”
Though any congressional action on the height limit could get tangled up on Capitol Hill for years, Issa believes there may be a window to start the debate this summer or fall, when Congress will be looking for nonpartisan issues to take up in an election year.
“If the mayor and Ms. Norton and I can all agree on it, my suspicion is we can get the president to agree on it,” Issa said.
Witold Rybczynski, a professor of urbanism at the University of Pennsylvania who has studied the District’s height limits, cautioned that carving out too many exceptions or segregating certain areas for taller buildings could quickly disrupt the city’s modest scale.
“It always starts incrementally, and then 10 years later they come back and do it again,” Rybczynski said. “It really is a slippery slope. The iron-cladness of D.C.’s law, because Congress controls it, is what makes it such an exceptional city.”
