The city council specified in a statement that the passage
had been done "on an emergency basis (pending passage of permanent legislation)."
The bill will symbolically rename
the stretch of Wisconsin Avenue in front of the embassy to 1 Boris Nemtsov Plaza, adding that name to the street sign.
Nemtsov was shot and killed on a bridge near the Kremlin in February 2015, while walking home with his girlfriend.
Kremlin spokesman Dmitry Peskov suggested the street name change further illustrated division between the US and Russia.
"I would probably have left this without comment, stressing only that it is up to the city authorities at the time but at a time when the state of bilateral relations between our two countries still leaves much to be desired, to put it mildly," he said.
A proposal to rename the street after Nemtsov was first brought up by Sens. Marco Rubio, R-Florida, and Chris Coons, D-Delaware, in Congress, but they were unsuccessful.
This isn't the first time a Russian Embassy's address has been honorarily renamed. In 1987, street signs outside the then-Soviet Embassy were changed
to include the moniker of Andrei Sakharov, a Soviet human rights activist who had been placed under internal exile.
Andrei Sakharov Plaza encompassed the one-block area that is now where the Russian ambassador's residence stands.
