A lawyer for the 32-year-old supervisor asked for more time to review the police report before entering a plea. Attorney Chris Andrian said he just received the report in court.
"It's my job now to look at it and see what it is," Andrian said.
No settlement offer has been extended, he said, but negotiations were expected involving the prosecutor and woman's attorney before the next hearing Dec. 13.
"It would be fair to say that over a period of time we'll go into discussions," Andrian said.
The woman's lawyer, Rosanne T. Darling, said her client is still dealing with the aftermath of what she called a frightening experience.
"There's a lot she has to live with now," Darling said outside court.
Darling said no civil lawsuit is planned at this point.
Carrillo declined to comment as he left the court. His parents and girlfriend were among supporters who attended the arraignment.
The lesser charge means his political career is no longer immediately threatened. If he had been charged with and convicted of a felony, he would have been removed from office.
The Board of Supervisors has been pressed by some of his critics to take action, including possibly a censure of Carrillo.
Chairman David Rabbitt said Friday that supervisors would simply have to let the legal process play out.
"I don't see this as a distraction," he said. "The potential charges were of such greater magnitude. Nothing would have been one extreme. This was slightly uphill from nothing, to be honest."
However, some of Carrillo's sharpest critics have continued to vow action on a recall effort. They said they would meet soon to discuss next steps.
If convicted of peeking, Carrillo faces up to six months in jail and a $1,000 fine, Hunt said.
Local rules prohibit a person charged with peering into an inhabited building from participating in a first-time offender program leading to a dismissal.
But Carrillo could end up settling for a different charge that would result in an alternative sentence that avoids jail time.
He was arrested in his west Santa Rosa neighborhood July 13 on suspicion of prowling, a misdemeanor, and burglary, a felony.
Santa Rosa officers responding to a pair of early morning 911 calls from the woman found Carrillo nearby in just his socks and underwear and carrying a cellphone.
Her bedroom window screen was torn, police said. The woman told investigators she awoke to the sound of rustling blinds and saw a man, later identified as Carrillo, standing outside the window.
In her second 911 call, she said the person knocked on her door, identified himself as a neighbor and ran away.
Carrillo was arrested when he could not offer an explanation for his behavior, police said. Investigators have repeatedly said they think Carrillo intended some type of sexual assault.
After posting bail, he reportedly checked in to an alcohol treatment facility, where he said he remained for five weeks.
On his return to the Board of Supervisors Aug. 20, he apologized and described a longtime problem with binge drinking.
While not detailing his specific actions, he suggested his behavior had undermined the woman's "absolute right to enjoy the peace and quiet of her home."
