"He is seeing his private physician" for the injuries, he said.
The fire was reported at 11:34 a.m. at Nolte's secluded Bonsall Drive home. The electrical fire started in the living room, and Nolte smelled the smoke from an upstairs bedroom, said fire Inspector Frank Garrido.
The Sheriff's Department said Nolte broke a window to escape.
Garrido said he then grabbed a garden hose and tried to extinguish the fire.
It took firefighters about 26 minutes to douse the blaze, which damaged a portion of the home, Garrido said.
The fire caused about $3 million in total damage, half of it structural damage and half damage to the contents of the home, including "collectibles, artwork, the furniture," Garrido said.
Nolte's publicist, Arnold Robinson, said in an e-mail that there was no one was injured.
Nolte has appeared in such films as "The Prince of Tides," "Affliction," "Down and Out in Beverly Hills" and "Tropic Thunder."
