ESA Letter and HOA Pet Registration Fee

[Graham Watts]

My tenant has provided my property management company with an ESA letter from a counselor that verifies the need for an emotional support animal. 

My property management company says that this means we cannot charge any additional pet fees (one time up front pet fee). They also said my HOA cannot charge the tenant the DNA pet registration fee that they require all dog owners to pay.

Is it accurate that the tenant cannot be charged a one time pet fee, and that the HOA cannot force the tenant to pay for and compete the DNA registration process?
