Hey Steve,
Just wanted to jump on here and let you know what happened in our situation with JeffCo. We looked for a property specifically for Airbnb purposes. Before closing, we sent the property to JeffCo to confirm it would meet all requirements. About three months after closing on the property, they reached out as we were about halfway through the process of registering as an Airbnb and informed us that the septic tank was too small for an Airbnb (they knew the size of the septic tank when they confirmed the property would pass). After all of that, we decided to push on and launch our Airbnb. Two things happened.
The market in Conifer was just not enough to cash flow. Cleaning fees and maintenance were through the roof due to it being so remote. We lost a lot of money in the first year.
The property finally stabilized in the second year, but then someone reported us and we got a cease and desist in the mail from JeffCo for not having the license. They gave us two weeks to shut down our property. Thankfully, the market had shifted and we rented it for one full year to a tenant that needed a finished property.
All that to say, run your math and see what the difference would be between renting on Airbnb (you may not have cleaning and maintenance fees if you're doing it yourself) and renting to either medium or long-term tenants. Once we rented long term, the property started cash flowing significantly more per month.
I hope this helps you in running your business without the government trying to shut you down. One last thing: I believe because you are not on a full acre, you cannot get the permit (rules might have changed; please check to confirm!). With that in mind, if you choose to fly under the radar, I would not contact JeffCo at all and I would be very careful about posting outside photos of your Airbnb. That way, no one will know where it is actually located.
Sorry you're even having to go through such a terrible process. I would try your best to stay clear of JeffCo unless you're sure you're going to get the permit. They have no idea what they're doing, and it's obviously a very un-American group of people who have been chosen to work there. Sad to see rules like this pop up in our backyard.
Best of luck!
