Homeowner not responding to tenant violation of bylaws

our bylaws state that no commercial vehicles are allowed to park in the development (unless it's in their garage). Our PM has sent several letters to the homeowner asking them to have their tenant park their commerical vehicles (with several ladders on top) in the garage or outside the development.

The homeowner has not responded.

My question is, can the Association ask the PM to send a letter directly to the tenants since the homeowner has not responded after several letters. The homeowner is currently being fined for the violation.

thank you,

Maureen
