Many municipalities have recently extended residence restrictions for sex offenders beyond the provisions of state law, although the efficacy of these measures in reducing recidivism has not been empirically established. This study used arrest histories in Jacksonville, Florida, to assess the effects of a recently expanded municipal 2,500-foot residence restriction ordinance on sex crimes and sex offense recidivism. Using a quasiexperimental design, pre- and posttest measures of recidivism were compared, and no significant differences in citywide sex crimes or recidivist sex crimes were found. In addition, time-series analysis revealed no significant differences in sex crime trends over time when compared with nonsex crimes from the same offender sample. After controlling for several demographic factors, individual-level multivariate results indicate that the timing of the residence restriction policy was not associated with a meaningful change in sex crime arrests or sex offender recidivism after the policy implementation date, suggesting that the residence restriction did not achieve its intended goal of reducing recidivism.
