What key update took place in the issuance of certificates starting in 2020?

The correct response highlights a significant change in the conditions under which certificates are issued, reflecting adjustments made to align with evolving regulatory requirements or industry standards. This may imply stricter criteria for qualification, modifications in the renewal process, or updated compliance measures that applicants must meet. Such changes are crucial for ensuring that all licensees adhere to current laws and practices, which can enhance the overall integrity and safety in the manufactured housing sector.

Understanding the context around this update is important as it showcases the state's commitment to maintaining high standards within the industry. It indicates proactive measures to address potential gaps or challenges that may have emerged prior to 2020, fostering a more responsible and well-regulated environment for manufactured housing.

In contrast, the other options focus on aspects that, while relevant to the broader context of certificates, do not align with the key update reflected in the question. Increased fees pertain to financial aspects rather than conditions. The transition to digital certificates signifies a technological advancement rather than a change in rules. New training requirements address educational standards but do not specifically pertain to the conditions surrounding the issuance of certificates.
