Quick Answers

The questions we get most.

More questions? Call us: (401) 484-8079

Zoning
Does my backyard qualify?
Most Rhode Island residential lots qualify. We need roughly 13×30 feet of clear space plus standard setbacks (usually 5–10 feet from property lines). RI law now requires municipalities to allow ADUs by right. We confirm everything free at your site assessment.
Financing
How do I finance the $140,000?
Most clients use a HELOC against their existing home equity. With RI median home values at $520,000, most homeowners have $175,000+ available. Personal loans and cash work too. We don’t require a specific lender.
Financing
What’s the payment schedule?
Four milestone payments: 30% at contract signing · 30% at framing · 30% at rough-ins · 10% at Certificate of Occupancy. You never pay for work that hasn’t been done.
Build
Who handles the permits?
We do — every single one. Building, electrical, plumbing, mechanical, zoning compliance. We file everything the day the contract is signed and manage every inspection through Certificate of Occupancy. You make zero calls to the town.
Build
What does “turnkey” mean exactly?
When we hand you the key, the unit is complete — kitchen installed, bathroom finished, flooring down, HVAC running, lights on, CO in hand. The only things left for you are furnishings and finding a tenant.
Value
Does the ADU add value to my property?
Yes — significantly. A permitted, CO-issued ADU with rental history is appraised as income-producing real estate. RI multi-family homes command a $75,000–$150,000 premium over comparable single-family homes. Your ADU creates that same dynamic on your existing lot.
Income
How fast will I find a tenant?
Rhode Island rental vacancy is under 3% — among the lowest in New England. Most clients have a tenant lined up before CO is even issued. A brand-new, fully appointed 1BR/1BA in a private backyard setting commands premium rent and rents fast.
Use
Can I use it for a family member?
Absolutely. Many clients build for an elderly parent, adult child, or in-law. There’s no requirement to rent it out. You can use it as family housing and convert to a rental at any point — the unit is fully permitted and legally habitable either way.
