Which dept oversees Permit Sonoma aka PRMD

Dear friends and neighbors, Would some kind souls please share with me which department oversees Permit Sonoma aka PRMD? And how to make a complaint against them? Supervisor, Lynda Hopkins' office has "tried" to speak on my behalf, but I can read between the lines that I'm not a big enough fish for the supervisor's office to risk rupturing it's relationship with PRMD.Feel free to post here or send me a private message. Thank you in advance for your help.
