Authorities are now working to determine what may have caused the four-bedroom, four bath home to go up in smoke.
Several reports said the circuit court judge had received death threats over the past few weeks following her decision to prevent the state from handing over sensitive voter registration documents to the federal government.
Trump's Department of Justice had requested South Carolina officials turn over the personal data of more than 3.3 million voters, including names, addresses, birth dates, driver's license numbers and the last four digits of their Social Security numbers.

South Carolina Circuit Court Judge Diane Goodstein issued a decisive ruling against the Trump administration last month
The decision put Goodstein at odds with both the Trump administration and South Carolina GOP Governor Henry McMaster, who filed an emergency petition to appeal the lawsuit and the temporary restraining order on September 5.
There is no suggestion of any MAGA link to the fire, but Democrat Congressman Daniel Goldman took to X to slam Trump's Deputy Chief of Staff Stephen Miller for 'doxxing' judges.
'Stephen Miller and MAGA-world have been doxxing and threatening judges who rule against Trump, including Judge Goodstein,' Goldman wrote.
'Today, someone committed arson on the Judge’s home, severely injuring her husband and son. Will Trump speak out against the extreme right that did this??'
Miller was quick to respond, branding Goldman's suggestion 'deeply warped and vile.'
Diane Goodstein, 69, was out walking on the beach when the suspected arson attack happened - just weeks after she had issued a decisive ruling against the Trump administration.
