Inmate Mail Policy

Inmates are permitted to send and receive unlimited letters each day in order to maintain communications with their legal representatives, families, friends, business associates, and government authorities. Two categories of mail are defined as:

  1. Regular Correspondence - Communication to or from inmates through letters. Incoming mail is inspected to prevent the following:
    • Transmission of contraband, i.e. drugs or any other prohibited materials or substances into the facility.
    • Escape plans.
    • Criminal conspiracies.
    • Any other type of threat or compromise to the over-all security of the facility and/or the safety of staff and inmates.

  2. Legal or Special Correspondence - Mail between an inmate and:
    • All state and federal elected officials.
    • All state and federal officials appointed by the Governor or the President of the United States.

    • All state and federal judges and courts.
    • An attorney at law registered with a state bar association.
    • The State Corrections Standards Authority.

    Incoming legal mail is opened and inspected in front of the inmate.  Outgoing legal mail may be inspected in the presence of the inmate then sealed and processed with other outgoing mail.

  • Narcotics, marijuana, handcuff keys, hacksaw blades, postage stamps, stickers, etc.
  • Pictures or Polaroid photographs depicting nudity, gang graffiti and/or groups raised decorative stickers, personal checks, etc.
