The actress Felicity Huffman reported to a minimum-security federal prison camp in the San Francisco Bay Area on Tuesday to begin serving a 14-day sentence for her role in the college admissions scandal, according to a representative for Ms. Huffman.

The Federal Correction Institution in Dublin, Calif., about 40 miles east of San Francisco, consists of a low-security facility housing 1,052 female inmates, and an adjacent minimum-security satellite camp with 175 more female inmates, now including Ms. Huffman.

The camp is based in an old prison facility, but like most federal minimum-security camps, it allows the inmates considerable freedom. Security is so low, in fact, that inmates have sometimes walked right out of the camp, though such incidents are rare. The cells are left unlocked, according to a Bureau of Prisons official who spoke on the condition of anonymity because the official was not authorized to speak publicly. The camp houses many white-collar criminals, but also holds gang members and drug couriers, including some who are serving multiyear sentences, the official said.

A Bureau of Prisons office in Grand Prairie, Texas, generally makes decisions about where federal inmates will be housed. At the request of Ms. Huffman’s lawyer, the judge who sentenced Ms. Huffman recommended that she be designated for “a facility commensurate with her security level closest to Dublin, California.”
