Here's my story around your question.
I'm in Mendocino County, and host in my home where I'm a permanent full time resident. In order to become legal (with my use permit and business license), I submitted the blueprints and permits for my home, well & septic, plus current photographs of my home, property, parking, surrounding area, and stating my case why I should be approved. This went to the Planning and Zoning department in the form of packets, one for each Planning Commissioner and for the staff Planners who did the initial work. Before the public hearing, the various health and safety agencies investigated and signed off on my location. This included septic, well, parking, fire safety at the house and evacuation plans; neighborhood safety and noise, road and driveway conditions. There were also fees for processing the application.
The public hearing went well, the planning commissioners had excellent questions, mostly about health & safety concerns, including plumbing, building maintenance, roads, fire, evacuation. As hosts we are intrinsically responsible for those things. After the Planning Commission approval was the approval of the County Supervisors, and my consent to the terms of the County Ordinance. We were given quiet hours, limit of number of guests & cars, no events or amplified music, no fires or open flames, no camping, no RV's, and the requirement of having business insurance for fire and public liability. Once my permit was issued, I received a license to post showing that I was required to collect TOT and submit it to the County, to be posted where guests can read it.
The process took about 6 months after I assembled my packets. The cost was about $5,000. It was an excellent learning experience. All the rules and regulations are appropriate. Public health and safety are paramount, as are community and neighborhood relations. The powers that be were supportive, and clearly wanted me to succeed. It was not at all adversarial.
Best of luck to you!
