This is in an attractive suburb with highly ranked schools and a brand new hospital 1.5 miles away.

so yes you want to look for something where and what are trying to attract ?

Once the family members with disabilities or who are sixty-two (62) years of age or older, or any other family member, no longer reside(s) in the premises on a permanent basis, or the title is transferred, the property owner shall notify the zoning official in writing, and the accessory family dwelling unit shall no longer be permitted, unless there is a subsequent, valid application.As you can see, it's really all up to the zoning department of that city or town, and my guess is that if your proposed use doesn't meet the above, they will not approve it.It doesn't really sound like they're talking about an entirely separate structure, so if that's true then the question about getting bank financing for such construction would be moot, but it's possible I'm reading the above wrong.As far as whether you can build on the empty small lot in general, you'd want to look up the zone of the lot on the assessor page and then look up the Permitted Uses section of the Cranston zoning ordinance to see what can be built there and Zoning Districts Designated to see if your lot meets the minimum lot size to build something.

You might find that the site will be classified as an "attractive nuisance", so be sure to follow the rule of the town and insurer so you don't get sued if a bunch of drunk teenagers get hurt in there.Good luck!

Construction, design, development, etc).

@Rob Shah to echo what @Mark Ainley said, there just aren't many areas where the buildings are designed to be rentals.

Or worse, leave the house abandoned which would attract far worse energy.

The whole foundation system is modular and installs in 1 day.We do meet state and city requirements and have approvals in Sonoma, Marin, and a few other counties as well as working to get approval for a primary dwelling in Mill Valley and Fairfax.The structure can be disassembled and moved easily because of how it's designed but it's far too big to be considered "mobile". 

House has great valley/mountain views, is close to national park and other attractions, and is on a half acre lot with much potential to develop in the future for additional outdoor amenities. 

If the springs somehow busted, the locking mechanism on the chain and the gears of the motor would hold the door in place - the springs ease the weight, they don't hold it, the lock is designed to hold the weight without the springs.
