Habsburg has lived in Salzburg, Austria, since 1981, and resides in Casa Austria, formerly called Villa Swoboda, in Anif, near the city of Salzburg.
On 31 January 1993 in Mariazell, he married Baroness Francesca Thyssen-Bornemisza (born 7 June 1958 in Lausanne), the only daughter of Baron Hans Heinrich Thyssen-Bornemisza de Kászon, a European industrialist, and his third wife, the fashion model Fiona Frances Elaine Campbell-Walter.
The marriage received the dynastic authorization of Karl's father, as head of the House of Habsburg, despite objections from some members of the family inasmuch as the bride, although a baroness in the nobility of pre-republican Hungary and Transylvania, did not descend in the canonically legitimate male line from a family of dynastic (ruling or formerly ruling or mediatised) status, as does his younger brother Georg's wife.

In July 1998 an Austrian court fined Karl von Habsburg 180,000 schillings ($14,300); he had failed to declare immediately to customs officials that he had an antique diadem in his luggage when he crossed the border from Switzerland in July 1996.
The diadem belonged to his wife who intended to wear it at a wedding ceremony.
After 10 years of marriage, the couple separated in 2003.

Karl and Francesca have three children:
Eleonore Maria del Pilar Iona Christina Jelena (born 28 February 1994 in Salzburg).
Married civilly to Jérôme d'Ambrosio on 20 July 2020.

Ferdinand Zvonimir Maria Balthus Keith Michael Otto Antal Bahnam Leonhard (born 21 June 1997 in Salzburg).

Gloria Maria Bogdana Paloma Regina Fiona Gabriela (born 15 October 1999 in Salzburg), her godmother is Gloria, Princess of Thurn and Taxis.

Habsburg said in an interview about private life in the 21st century: "If you don't deliver results, you won't get any further.
There are no inherited laurels to rest on.
And I don't see anyone in my family who has a problem with that."
Regarding the racing profession of his son Ferdinand: "I'm pretty relaxed now.
When I think about how often I took him to the hospital with broken bones after a kart race!"

In March 2020, during the COVID-19 pandemic, he tested positive for the virus.
Habsburg said he felt good and fearless and was self-isolated at home.
He was the first royal person and head of a royal house to contract the virus.
Habsburg was officially declared healthy after almost three weeks of quarantine. "
However, the situation makes it necessary to stay at home.
It is the best way to curb the spread of the virus," he said. "
One must now bear responsibility in freedom, to take care of ourselves and thus of our fellow human beings".
After his illness, Karl von Habsburg encouraged everyone to follow the official protective measures strictly, and asked survivors of the disease to donate blood plasma.
