Cal. Penal Code § 4485

Moneys in the fund may be available for the construction, reconstruction, remodeling, and replacement of county jail facilities, including, but not limited to, separate facilities for care of mentally ill inmates and persons arrested because of intoxication, and the performance of deferred maintenance on county jail facilities except that up to twenty million dollars ($20,000,000) of the money in the fund shall be available for the construction, reconstruction, remodeling, and replacement of county juvenile facilities, and the performance of deferred maintenance on county juvenile facilities. However, deferred maintenance for jails and juvenile facilities shall only include items with a useful life of at least 10 years. Expenditure shall be made only if county matching funds of 25 percent are provided as determined by the Legislature, except that this requirement may be modified or waived by the Legislature where it determines that it is necessary to facilitate the expeditious and equitable construction of state and local correctional facilities.
