What Is an ADU?
An ADU (accessory dwelling unit) is a smaller, fully independent home built on the same lot as your main house. People also call them tiny homes, in-law suites, or backyard cottages. Each one has its own kitchen, bathroom, and living space. Our floor plans range from a cozy 475 sq ft Studio+ up to a roomy 816 sq ft two-bedroom, so there is an option for almost any yard and budget.
Families across Coralville use ADUs to house aging parents, create multigenerational living arrangements, generate rental income, or simply add long-term value to their property. You can browse our floor plans to picture what might fit your lot.
Why Build an ADU in Coralville?
Coralville’s location next to Iowa City makes it one of the most dynamic rental and residential markets in eastern Iowa. With the Iowa River Landing drawing shopping, dining, and entertainment, and the University of Iowa just minutes away, demand for quality housing here stays strong year round. An ADU can offer steady rental income or a private place for family to stay close.
For families who love the outdoors, properties near Coralville Lake offer a perfect setting for a guest cottage or weekend retreat. Whatever your goal, working with a dedicated ADU builder Coralville residents recommend means your project fits both your land and the local character.
The SF-592 By-Right Law
Building an ADU in Iowa is easier than ever thanks to a new state law. SF-592 allows ADUs by right in every city and county in Iowa, including Coralville. That means homeowners no longer need special approval just to be allowed to build one. Keep in mind that setback requirements still apply, so your ADU has to sit a certain distance from property lines. Our team knows how to plan around those rules, and we take that worry off your plate.
You can learn more about how accessory dwelling units support housing options from the U.S. Department of Housing and Urban Development, a trusted federal resource.
Permits: Timeline and Cost
Many Coralville homeowners are surprised by how quick the permit process can be. An ADU building permit in Iowa typically takes about 3 days to 2 weeks to be issued. The cost usually ranges from a few hundred dollars up to a couple thousand dollars, depending on the city. As your ADU builder Coralville families rely on, we prepare and submit your paperwork for you, so you are not stuck deciphering local requirements alone.
Pricing and Financing
Every project is different, so we speak in honest ranges rather than one-size-fits-all numbers. Your final investment depends on the floor plan, finishes, site prep, and utility connections. Visit our pricing page to understand the factors involved, and review your financing options to see what monthly payments might look like.
