The addresses for more than 1,000 state-licensed care facilities for vulnerable people in California matched addresses on the state sex offender registry, according to a newly released audit.

State Auditor Elaine M. Howle said the California Department of Social Services failed to check the sex offender registry even after her office advised it to do so in 2008.

The facilities matching the registry of sex offenders included foster homes, group homes and day-care facilities for children, as well as facilities for adults with special needs and the elderly.

The auditor informed state regulators of the 1,000 sex offender hits in July. Investigations are now complete and the state said eight licenses have been revoked or suspended and regulators issued 31 orders barring individuals from licensed facilities.

The audit was ordered earlier this year at the request of state Assemblyman Henry Perea (D-Fresno). The audit was also intended to compile data on deaths of children who were under the oversight of child protective services.

The Los Angeles County Board of Supervisors balked at subpoenas for information and hired outside lawyers to fight the inquiry. The auditor's office has vowed to continue to press the county for records and to issue a second report in the coming months.

For the record, 3:04 p.m. Oct. 27: An earlier version of this article incorrectly said more than 1,000 sex-offender addresses matched the addresses for foster homes and group homes. That account was based on a summary of the report provided to journalists by the state auditor. In reality, the sex offender matches included a wider group of state-licensed facilities, including day-care facilities for children and providers for the elderly and adults with special needs. Additionally, the state auditor said that regulators issued 36 orders barring individuals from licensed facilities. The true number is 31, according to the California Department of Social Services.
