House Arrest/Home Detention
In this program, an inmate with at least 30 days remaining on his/her sentence (15 actual days ½ - time credits) is allowed to remain at or return home under intensive supervision and monitoring.  An electronic device mounted on the individual's ankle allows EMP Staff to supervise the inmate closely at all times. The inmate can continue to live at home, maintain employment, attend school, or vocational programs and participate in treatment.  Frequent field contacts are made by EMP Staff along with random home searches and drug/alcohol testing. The inmate must have prior approval from EMP Staff to leave home for any reason.  The inmate's daily schedule must be approved by the EMP Staff. Participants are also subject to surveillance at any time. If the inmate is away from home or work without permission, tests positive for illegal drugs, or becomes a risk to the community, the inmate can be returned to jail.

If accepted, there is a $50 initial deposit payable within three (3) days of starting EMP and a per day rate for each day to be served.  The initial deposit will be applied toward your total EMP cost.  The per day rate is determined by a sliding scale which is based on your income – (sliding scale chart below).

(hourly earning rate)
Per Day Rate
 $0.00 – $24.99
 $25.00 – $39.99
 $40.00 & Over

For an inmate requiring a higher level of supervision while on EMP, other devices are available such as continuous alcohol monitoring and Global Positioning System (GPS) monitoring. Alcohol use is monitored by a breathalyzer or a transdermal device attached to the ankle. With GPS, a transmitter is also attached to the ankle of the inmate. The GPS transmitter sends a signal to a GPS satellite and transmits data using a cellular network. A GPS transmitter tracks an inmate’s movement 24 hours a day. 

All applicants will be screened by the Probation department for eligibility. The following factors will make an applicant ineligible:

  • Court order prohibits EMP or Early Release Programs
  • PC 1170(h) or PRCS cases
  • Sentence with less than 15 actual days remaining
  • Outstanding warrants, a detainer, probation, parole or immigration holds
  • Pending new charge
  • Excessive criminal history and/or prison priors
  • Does not have a verifiable residence in Santa Clara County

Cases involving crimes of a violent or sexal nature are typically ineligible for EMP, but will be screened on a case by case basis.

Court recommended EMP commitments will receive a great deal of consideration when screened for acceptance, but may still be rejected, especially if there are significant safety concerns.
