Is it legal for condo owners to be allowed to know who your bonding agency is?

It is unclear from your question whether you are a prospective tenant or a prospective vendor.

A condominium owner who rents out a unit has a certain obligation to the community in terms of vetting a tenant.

Some governing documents require that an owner produce details about a tenant, including but not limited to

  • A credit check
  • A background check
  • References from other landlords
  • And so forth

If you are a vendor proposing services to an association, it's reasonable that the association require proof of your insurance, bond, and license. The association may be required by its governing documents to only hire vendors with these proofs.
