House arrest was expanded in October 1984 to control facility population and to promote offenders' successful return to society. Placements per month were 222 in the first year and 237 in the second year; population by the end of year two was about 1,400. Misconduct terminations decreased from 45 percent to 40 percent, while new arrest terminations increased from 6 percent to 14 percent. The number of DUI offenders increased and the number of sex offenders decreased because of eligibility criteria changes. Offenders with burglary, larceny, forgery, unauthorized vehicle use, and escape charges fared worse than the overall rate, while offenders with DUI, drug, robbery, and assault charges fared better. Success on house arrest increased with age and decreased as security levels from which offenders were referred increased. Ninety percent of first-year participants had not been reincarcerated a year and a half after house arrest. Increases in offenses committed under house arrest made the project unpopular with district attorneys, law enforcement, and the public. House arrestees did no worse or better than offenders discharged without participating in house arrest, but State costs for house arrestee supervision were $1,400 per year, compared to $12,000 per year for housing inmates in community treatment centers. 19 tables and 1 figure.
