Garage conversion, zoning

[Hunter Broschinsky]

Hey guys! I've finally recouped some capital after buying my first home and am looking to use it to convert my 420 square foot garage into a small studio apartment ( 1 bedroom, 1 bath, kitchenette). My contractor is telling me that I don't have to get it permitted as a ADU but only livable space. Not really sure if that's true or not. Im also considering to get it permitted as a short term rental but have some questions. My zoning code is RS so I thought I could have a short term rental as long as I lived on the property (which I am this is my primary residence). When I check out airbnb there is nothing near my house, I live about 12 minutes east of the ocean, it seems like the only places available are in the downtown district.
