The decision comes after a week of protests against systemic racism and police brutality.
Prompted by the death of African-American George Floyd in police custody, the US capital unanimously voted for new measures to policing.
The emergency legislation prohibits the use of neck restraints, similar to the actions used against Floyd.
The vote also commands the release of names and images from officers’ body cameras, following “an officer-involved death or the serious use of force”.
The decision also places new restrictions on Metropolitan Police hiring procedures.
Police will be unable to hire people with a documented history of police misconduct and limits have been introduced on expressions of non-deadly force.
Robert White, a district council member said: “There’s no question whatsoever about whether we have to significantly reform our policing. The only question is whether we and our policing leadership are ready to step up to that challenge.”
Speaking in a statement read by the council’s chairman, Phil Mendelson, Mayor Muriel Bowser believed the legislation was a positive change but decisions should be influenced by the public.
DC police chief Peter Newsham told a news conference police had already introduced several reforms in the past two decades.
Mr Newsham explained he would consult with Charles Allen, the council member who introduced the legislation, to discuss any concerns.
Trump had initially enlisted thousands of troops and federal law enforcement to control outbreaks of looting and violence.
The President tweeted four days ago: “they will be going home but can quickly return if needed.”
Researchers believe these protests were the most sweeping and sustained in the country’s history.
Washington, DC’s Metropolitan Police Department has a history of being under review for excessive force.
In 2001, the US Justice Department revealed the Metropolitan Police Department had shown cases of use of excessive force alongside other issues.
The revelation sparked federal oversight of the department.
A move that led to the appointment of an independent monitor, until 2012.
