California Business And Professions Code Section 7210.7

The board may authorize schools licensed by the board or instructors employed by those schools to provide home training in the use of guide dogs. If a school desires to provide home training in the use of guide dogs, it shall apply to the board and provide the board with a written plan and procedure for conducting that home training, which shall be approved by the board prior to conducting any home training. Schools providing home training in the use of guide dogs shall, annually, provide the board with the names and addresses of those persons who are receiving home training and shall include those persons who have received home training from the school subsequent to the last report filed with the board. The guide dog user, as a condition of receiving home training, shall have completed a formal in-residence training program from a school licensed by the board to provide guide dog training, or from a school recognized by another state to provide guide dog training. The requirement for a formal in-residence training program from a school licensed by the board may be waived by the school when that requirement imposes an undue hardship on the guide dog user. Home training, as provided in this section, shall consist of not less than 20 hours of training. This section shall only apply to those schools that are licensed by the board to furnish guide dogs and to train persons to use guide dogs, who desire to provide home training in the use of guide dogs, and who apply to the board for approval to provide that home training.
