Plenty of parking in the back which could be leased out to an expanding landscaping company, or winter storage for boats, RV's, etc.

I am looking at purchasing a duplex in Indianapolis, Indiana that has a garage that has been converted to a storage area.

In at least one rural Idaho County, Butte County, their policy is that tenant’s items cannot leave their county and since there is no licensed and bonded storage facility, a landlord has to pay for a lockable pod to be transported into the county by a moving company!

I'm in a county jurisdiction that uses the IRC (International Residential Code).But we also have two RV's, a Tiny Home and a detached Studio that will eventually each draw unwanted attention and require either a license as a storage facility or permitting as a campground. 

Safe as long as the load (appliance/outlet/device) doesn’t have some special code requirement (like a bathroom outlet for example that must have its own breaker)2- some breakers (not many) allow two circuits to be directly connected in which case you wouldn’t have to change anything (but the inspector prob checked for that already)3- add a double Pole breaker (if panel is compatible) or another single pole breaker if there are empty slots available in the panel.4- if there are no slots available for additional breakers, and the double tapped circuits require them to have their own breaker then you will either have to replace the panel to one that has more spaces.

"The basement laundry and storage area is dusty".

Create a nice flyer, brochure, or other marketing device that includes an offer of a referral fee.

Typically, I will sign a storage agreement with the park that has a list of required repairs to bring the homes up to "park standards"(see below).

Ways to increase rent could be adding storage, covered parking, fencing may or may not work.
