I marked location of retention wall in original picture.

This house is currently a 2/1 but with the additional 480 sqft of living space (main bath, dinning, walk-in closet).

This would qualify even if the portion used for investment is a part of the main living space, because even though it's being used for investment it still qualifies as your primary residence.

Examples to kick it off: adding solar panels, vending machines, advertising space, allowing credit card rent payments w/ fee. 

If the space is big enough you could even add washer/ dryer. 

This includes 436 residential units (recently reduced from original plans of 460), a 5-story hotel, and 2 million square feet of commercial space, which has already been approved by the county.

So the camera is facing the tenants assigned parking space and it happens to get the other tenant unit in it as the same time?

The space is big enough for a bed, has a window, etc. 

I'm a licensed builder and have been actively building and renovating homes as my primary occupation while dabbling in the RE space buying properties, fixing them up and flipping/holding.

City of Destin has map marked out with restrictions, you should be able to find it easily with a quick google search.
