The original Royal Street mansion occupied by LaLaurie did not survive. The mansion, located on the corner of Governor Nicholls Street (formerly known as Hospital Street), commonly referred to as the LaLaurie or Haunted House, is not the same building inhabited by LaLaurie. When she acquired the property in 1831 from Edmond Soniat du Fossat, a house was already under construction and finished for LaLaurie. This house was burned by the mob in 1834 and remained in a ruined state for at least another four years. It was then rebuilt by Pierre Trastour after 1838 and assumed the appearance that it has today. Over the following decades, it was used as a public high school, a conservatory of music, an apartment building, a refuge for young delinquents, a bar, a furniture store, and a luxury apartment building.

The dwelling had a third floor and rear building added later in the 19th century, and the rear building on Governor Nicholls Street, which had only one floor until a second one was added in the 20th century, was remodeled in the 1970s when the second-floor interior of the building was done over by Koch and Wilson, architects. At three stories high, it was described in 1928 as "the highest building for squares around," with the result that "from the cupola on the roof one may look out over the Vieux Carré and see the Mississippi in its crescent before Jackson Square."

The entrance to the building bears iron grillwork, and the door is carved with an image of "Phoebus in his chariot, and with wreaths of flowers and depicting garlands in bas-relief." Inside, the vestibule is floored in black and white marble, and a curved mahogany-railed staircase runs the full three stories of the building. The second floor holds three large drawing rooms connected by ornamented sliding doors, whose walls are decorated with plaster rosettes, carved woodwork, black marble mantelpieces, and fluted pilasters.

In April 2007, actor Nicolas Cage bought the house for a sum of $3.45 million. The mortgage documents were arranged in such a way that Cage's name did not appear on them. On November 13, 2009, the property, then valued at $3.5 million, was listed for auction as a result of foreclosure and purchased by Regions Financial Corporation for $2.3 million. The property last changed hands in 2010 when it was purchased by current owner Michael Whalen for $2.1 million (~$2.87 million in 2023).

For almost 200 years, there have been reports of paranormal activity coming from this house. It shouldn't surprise many that many hauntings are attributed to the slaves that Madame LaLaurie kept on the property. There is a room in the LaLaurie Mansion where slaves were often kept, and reports of moaning coming from that room are common. Phantom footsteps echo through the house with regularity. Many people who have stood near the house have reported feeling as if they were taken over by negative energy.
