Looking for an experienced ADU builder Winterset homeowners can trust? Tiny Homes of Iowa designs and builds custom accessory dwelling units across Madison County, blending modern comfort with the historic charm that makes Winterset so special. From the courthouse on the town square to the covered bridges in the countryside, this is a place where roots run deep, and an ADU lets your family put down a few more.
What Is an ADU?
An accessory dwelling unit (ADU) is a small, fully independent home built on the same lot as your existing house. It has its own kitchen, bathroom, sleeping area, and entrance. People call them backyard cottages, granny flats, or tiny homes, but they all serve the same purpose: adding flexible, comfortable living space without buying new land.
Our floor plans range from a cozy 475 square foot Studio+ to a roomy 816 square foot two-bedroom. You can explore the full lineup on our floor plans page to picture what fits your property and your family.
Why Build an ADU in Winterset
Winterset offers something many Iowa towns cannot match: historic character paired with generous lot sizes. Larger yards give an ADU builder Winterset families work with plenty of room to place a well-designed cottage without crowding the main home.
People here choose ADUs for several practical reasons:
- Housing aging parents close by while keeping everyone independent.
- Multigenerational living that gives adult children or relatives their own space.
- Rental income, especially with steady tourism drawn by the Bridges of Madison County and the John Wayne Birthplace.
- Added property value on lots near the beloved historic town square.
Visitors come to Winterset year-round, which makes a thoughtfully built ADU a smart long-term investment. Whether you want extra family space or a flexible guest stay, we handle the details so you can enjoy the result.
SF-592: ADUs Are Now Allowed By Right
A new Iowa state law, SF-592, allows ADUs by right in every city and county in Iowa, including Winterset and the rest of Madison County. That means you no longer need special approval just to be allowed to build one. This is a major change that removes one of the biggest hurdles homeowners used to face.
One important note: setback requirements still apply. Your ADU has to sit a certain distance from property lines, which is exactly where Winterset’s larger lots become an advantage. As your ADU builder Winterset neighbors rely on, we map out setbacks early so your design fits the rules from day one.
