Build Your ADU in Twin Falls With Expert Guidance at Every Step
We don't bid your project — we walk you through feasibility and design, then introduce you to a licensed contractor for permitting and construction, so you never feel lost. The Magic Valley's ADU planning team.
We're the Solution, Not Just Another Quote
Most homeowners don't search “ADU contractor” because they want a bid. They search because they're stuck on questions like:
- ✓“Is my lot even eligible for an ADU?”
- ✓“How big can I build — 500 sq ft? 1,200?”
- ✓“Should I convert my garage or build a detached unit?”
- ✓“HELOC or construction loan — what makes sense?”
- ✓“What permits do I need in Twin Falls?”
- ✓“What mistakes will cost me thousands?”
We answer every one of those questions — then guide you from first conversation to an introduction to a licensed contractor who builds it.

ADU Planning, Then a Licensed Contractor
We handle planning, feasibility and design. The licensed contractor we work with handles the drawings, the permits, and the construction through the final inspection walkthrough.
Feasibility Check
We assess your lot, zoning, setbacks, and utility access to determine exactly what you can build — before you spend a dime on design.

An accessory dwelling unit isn't just extra space — it's a financial asset and a lifestyle upgrade.
A permitted ADU is appraised as a separate income-producing unit — and its projected rent can even help you qualify for financing. Homes with ADUs have sold for more (FHFA), though that partly reflects where ADUs get built, so we lead with the income you can count on.
Twin Falls area rental demand is strong. A well-designed ADU generates consistent monthly income that offsets your construction costs.
Aging parents, adult children, home office, guest suite, or rental unit — your ADU adapts to your life as needs change.
Run the Numbers on Your ADU
What if your ADU paid for itself? Our interactive calculator lets you plug in real numbers — your construction cost, expected rent, interest rate, and loan term — and see exactly what your monthly payment looks like.
Then flip the switch: apply all your rental income to the principal and watch your payoff timeline shrink by years. It's the “aha moment” that turns an idea into a plan.

Idaho Law Is on Your Side
Idaho Senate Bill 1354 (effective July 1, 2026) requires larger Idaho cities — including Twin Falls — to allow at least one ADU per single-family lot. And Idaho House Bill 166 (2023) stops HOAs from banning an internal ADU on an owner-occupied homestead. Twin Falls already permits ADUs under its Uniform Development Code, so if you own your home here, the path to building is clearer than ever.
