What to do with 1500 sq foot duplex sitting on 17000 sq foot lot

[Kelsey Vander Meulen]

I have about 10000 square feet that is currently empty on a listing I'm considering purchasing. I'm brainstorming ways that I can most effectively use this empty space... The lot is zoned as R2 and currently only has 2 units on it....

RV/boat parking came to mind. Does anyone know how I would go about doing this? Is this legal? How would I advertise the space

I was also considering buying a few tiny homes and placing them on the empty portions of the lot. Does anyone have any experience doing this?
