Attached vs. Detached ADU: Which Do You Need?
Not sure which ADU type fits your property? Whether you're converting existing space or building new, understanding the scope helps you plan your budget and timeline with precision.
Attached ADU
This uses existing space you already have, a basement, garage, or an addition tied into your current home. No new foundation means faster timelines and lower cost.
What We Handle:
- Basement or garage conversion
- Egress windows & separate entrance
- Kitchenette or full kitchen install
- City permitting & code compliance
Perfect for: Smaller lots, faster turnaround, or lower upfront investment.
Detached ADU
A fully standalone structure in your backyard, built from a new foundation up. More investment, but complete separation from the main house.
What We Handle:
- New foundation & full structure
- Independent utility connections
- Full kitchen, bath, and living space
- Design matched to your main home
Perfect for: Larger lots, long-term rental income, or true multigenerational independence.
Real Rental Income, Real Multigenerational Living
Whether it's aging parents, an adult child, or a long-term tenant, an ADU gives your family real flexibility without sacrificing privacy. It's one of the most practical ways to add both usable space and long-term equity to your property.
From a basement conversion to a brand new detached unit, a Pro-Worx ADU is built to be code-compliant, rental-ready, and designed to genuinely fit how your family actually lives.

Utah passed SB284 in 2025, a statewide law taking effect October 1, 2026, requiring most cities to allow at least one internal or attached ADU on qualifying single-family lots.
If your city previously restricted or outright banned ADUs, that's changing. An unused basement or garage isn't just wasted space anymore, it's a genuine opportunity to add rental income or a private space for family.
At Pro-Worx Construction, we don't just convert space. We handle the specific permitting, egress, and code requirements that make an ADU actually legal and rentable in your city.
"A converted basement adds space. A properly permitted ADU adds real income and flexibility. We build for both, done right the first time."
Cities can still set reasonable standards on size, parking, and design, so we confirm your specific city's current ADU ordinance before finalizing any plan, from egress windows to separate utility metering.
Is Building an ADU a Smart Investment in Utah?
According to Harvard's Joint Center for Housing Studies, adding an accessory dwelling unit can raise a property's value by roughly 20%, on top of any rental income the unit generates directly.
The math is straightforward: a legal, permitted ADU is functional living space that both appraisers and buyers recognize as real value, not just extra square footage. Combined with monthly rental income or reduced housing costs for extended family, an ADU is one of the few home projects that can pay for itself over time.

- ~20% property value increase
- Direct rental income potential
- Ideal for: Rental Income & Multigenerational Living

"For Utah homeowners, the benefits go beyond the appraisal. We help families create real independence for aging parents or adult children, or a legitimate rental unit, without the cost of buying a second property."

An unused basement, garage, or backyard isn't just wasted space, it's untapped rental income or a private space for family. If that square footage sits unused, you're leaving real value on the table.

Private space for aging parents or adult children, without losing your own home's privacy.
