CA AB1520

Removes the privacy exemption for utility usage data of industrial, institutional, and commercial water customers, requiring local agencies to disclose their water usage rates upon request.

Maintains the privacy exemption for residential utility customers' names, credit histories, utility usage data, home addresses, and telephone numbers, with specified exceptions for authorized family members, government officials, law enforcement, and other limited circumstances.

Adds a new exception allowing disclosure of residential utility customer information when the local agency determines the customer has violated utility usage policies or holds elected/appointed official status with authority over utility policies.

Includes legislative findings that public interest in disclosing industrial, institutional, and commercial water usage rates outweighs privacy interests, distinguishing these commercial users from residential customers.

Specifies that no state reimbursement is required for this mandate as it falls within constitutional requirements for public access to local agency writings.
