How it works
From first call to move-in.
This is the typical Irontown Modular process. Foundation and site work run alongside the factory build, and a project manager is assigned to your project.
Talk it through
Tell us about your lot, your household and how you want the ADU to work. Is it a guest house, a home office, a place for family or a small primary home? We'll talk through access, utilities and the practical questions early, before you spend on design.
Pick a plan
Choose from the 10 Irontown plans we sell. Each is available in several finishes. We'll compare layouts with your lot and how you want to use the space, then confirm the plan and finish direction.
Feasibility on your lot and approvals
We review your lot for access, setbacks, utilities, slope and local requirements. The city or county makes the approval decision, and we do not promise an outcome. We coordinate the application with you and Irontown and tell you what we see before you commit.
State approvals for the modular design are handled by Irontown as part of their process.
Factory build and delivery
While foundation and site work happen on your lot, your modules are built indoors at Irontown's Utah factory. When the modules and your site are ready, they ship to you. A project manager is assigned to your project.
Set and finish
Modules are set on your lot and the finish work is completed. Stoneward stays your local point of contact through the final walkthrough and closeout.

Questions
Honest answers, before you start.
What is a modular ADU?
A modular ADU is an accessory dwelling unit built as one or more modules indoors at a factory, then shipped and set on your lot. The site work, foundation and finish work happen locally. Irontown Modular builds the modules in Utah.
Do I need permits?
Almost always, yes. An ADU is a dwelling, and your city or county will have requirements for zoning, setbacks, utilities, inspections and the building permit. The exact path depends on where you live.
Stoneward helps you identify and coordinate the approvals, but the jurisdiction makes the decision. We do not promise an approval outcome.
Can it go on my lot?
Sometimes. Access for delivery, setbacks, utilities, slope, drainage and local rules all affect whether a plan works. We start with a lot review and will tell you if a standard plan looks like a stretch. A site visit may be needed before anyone can answer with confidence.
How do I get pricing?
Request pricing and tell us your plan, city and lot situation. We'll put together a written quote that lays out the scope. Pricing and delivery are confirmed in that quote, not on this website.
What finishes are available?
Each Irontown plan is available in several finishes. We'll walk through the options with you and confirm your selections in the written quote.
