Building an ADU is a major project, and the final bill depends on a few key things. Site prep is a big factor; if your land is sloped or needs extensive utility connections, costs go up. The materials you choose—from siding to kitchen finishes—also change the math significantly. Whether you’re building a detached unit or converting an existing garage shifts the permit requirements and structural work needed. We provide exact pricing confirmed free on the call.

Iowa doesn't have statewide ADU laws, so regulations are set at the local level, including in Des Moines. This means you need to check the specific ordinances for your city or county. Factors like minimum lot size, parking requirements, and owner occupancy rules can vary. A local ADU specialist will be familiar with Des Moines' zoning code. They can confirm what's permissible on your property.
Yes, prefab or modular ADUs are an option for Des Moines homeowners. These units are built off-site and then assembled on your foundation. This can sometimes speed up the construction timeline. You'll still need to ensure the prefab model complies with Des Moines building codes and zoning. A specialized contractor can advise on the best prefab solutions.
