Which entity must associations register with annually?

Associations in Nevada are required to register annually with the Office of the Ombudsman for Common-Interest Communities and Condominium Hotels. This office serves as a resource for homeowners and associations, providing oversight, education, and support related to the governance of common-interest communities. Registering with the Ombudsman helps ensure that associations are following the state's laws and regulations, promoting transparency and accountability within the community management structure.

The other entities listed deal with different aspects of business and regulation but do not specifically pertain to the annual registration of homeowners associations. The Department of Business and Industry oversees various sectors but is not specifically focused on homeowners associations. The Financial Institutions Division primarily regulates financial entities and not community associations. The Nevada Housing Authority is involved in housing programs and policies but does not handle the registration of homeowners associations. Thus, the correct choice reflects the specific legal requirement for associations to maintain compliance with community regulations in Nevada.
