What is effective through 2019 regarding certificate endorsements according to NRS 489.551?

The correct answer is that endorsement of certificates is required, as stated in NRS 489.551. This regulation emphasizes the importance of maintaining competency and credibility within the manufactured housing industry. Certificate endorsements serve to validate that individuals are continually meeting industry standards, which is vital for ensuring quality and professionalism among licensed individuals.

Having a system in place for endorsing certificates helps to ensure that all licensed professionals are updated on current regulations, practices, and skills necessary to operate effectively in the field. This requirement helps to protect consumers by ensuring that those involved in the sale, installation, and management of manufactured homes remain qualified and educated about existing laws and best practices.

In contrast, transferring owners needing additional training, licensed dealers submitting a report, and property tax clearance being mandatory are related concepts but do not specifically address the requirement for certificate endorsements as stated in the question. These alternatives may also reflect important regulations concerning the broader context of manufactured housing but are not directly connected to the endorsement of certificates through 2019 as specified in the relevant statute.
