Airbnb said it would build off previous action taken to curb social unrest following Charlottesville riots in 2017.
Steps include measures to flag those booking under bogus names and fake accounts.
"Members of hate groups are never welcome on Airbnb and we have previously taken action to remove these individuals from the Airbnb community," reads the new safety plan.
The city's hotels have also taken extra security measures and vetting of bookings ahead of next week, though some details are being kept private.
Hilton's DC properties including Capital Hilton, a hotel neighbouring the Mall and White House, are reviewing group bookings.
"We don't get into the specifics of our security posture publicly, but the preparation is always well informed and mindful of current events," Nigel Glennie, spokesperson for Hilton Hotels & Resorts told USA Today.
"The teams at these hotels are very experienced and have a long history of successfully managing through major public events."
Wyndham Hotels & Resorts, another large accommodation provider in Washington, says have also responded to curb the actions of potential trouble makers. The chain have a number of franchised hotels around downtown Washington, which will be used by those attending next Wednesday's inauguration.
"We have provided our hotels with additional security measures to consider, and we are encouraging them to follow guidance from local authorities," Rob Myers of Wyndham told USA Today.
