Thanks to all who sent links to the Washington Post update:
“The District’s Zoning Commission gave final approval Monday night to new regulations governing the “pop-up” homes sprouting up in some of the city’s gentrifying neighborhoods, reducing the maximum height of single-family rowhouses to 35 feet from 40 feet.
The new regulations affect only neighborhoods in the city’s “R-4” zone — which includes some of the city’s most vibrant residential areas, such as Capitol Hill, Adams Morgan and Columbia Heights. The regulations go into effect immediately.”
