The Jefferson was purchased in June 2005 by DC CAP Hotelier, a New York-based real estate firm.
Loews managed the hotel until July 2005, after which the owners hired Kor Hotel Group, a Los Angeles-based manager of luxury hotels, as the hotel's new overseer.
By now, The Jefferson had 32 suites, and had created about 2,500 square feet (230 m²) of meeting space.
This space was divided among five rooms, which had occupancy limits ranging from 15 to 150 people.

Kor Hotel Group began a major redesign of the hotel in 2005, and The Jefferson closed in March 2007 to begin its overhaul.
During the renovations, the building's skylight was uncovered for the first time in decades, and the lobby's dropped ceiling was removed to expose the original barrel vault.
Many of the building's structural elements were repaired, strengthened, and upgraded, and the HVAC and mechanical systems gutted and replaced.
The hotel was expected to reopen on September 1, 2008, but much more structural deterioration had occurred than was anticipated and the hotel did not reopen until August 2009.
Renovated guest bathrooms now featured television screens embedded in the mirrors and deep "soaker" bathtubs, while guest living and sleeping spaces now featured individualized custom drapes and custom-designed beds covered in European linens featuring images of Jefferson's Virginia home, Monticello.
The overall feel of guest-rooms was meant to reflect a Paris apartment.
The hotel cocktail lounge was completely remodeled as well, and now featured an orange colored bar countertop of molded glass embedded with optical fibers that made it glow.
The hotel retained its Federalist interior design style in its public spaces, including the unique antique furniture, artwork, and displays of Jefferson-signed documents.
New amenities included a butler assigned to each guest-room, and room service trays containing microchips that alerted staff whenever the tray was deposited in a hallway.
The cost of the renovation was not disclosed.

The Jefferson continued to emphasize its discretion and private nature after the 2008–2009 renovation.

The hotel increased its prices after the renovation by about $100 ($119 in 2019 dollars) a night.
Off-season standard guest-room rates ran from $380 ($453 in 2019 dollars) to $450 ($536 in 2019 dollars) a night, while height-of-season rates ranged from $450 ($536 in 2019 dollars) to $650 ($775 in 2019 dollars).
Suites went for $850 ($1,013 in 2019 dollars) a night.
The new prices made The Jefferson one of Washington's priciest hotels, alongside the Four Seasons and The Ritz-Carlton.
