If you are searching for an ADU builder Grimes homeowners can trust, you are in the right place. Grimes is one of the fastest growing communities in the north metro, and that growth has created a real opportunity. Larger lots, newer subdivisions, and steady demand for flexible living space make this a perfect setting for an accessory dwelling unit. As an experienced ADU builder Grimes families rely on, we handle design, permitting, financing guidance, and construction so you can focus on the future, not the paperwork.
What Is an ADU?
An accessory dwelling unit (also called a tiny home, granny flat, or backyard cottage) is a fully independent living space built on the same property as your main house. It has its own kitchen, bathroom, and entrance. Our floor plans range from a cozy 475 sq ft Studio+ to a spacious 816 sq ft two-bedroom layout. You can explore options on our floor plans page to picture what fits your yard and your goals.
Why Build an ADU in Grimes?
Grimes is defined by rapid suburban growth and the kind of larger lots that give homeowners room to build. The rapidly expanding north-metro neighborhoods often include generous backyards and side yards that are ideal for a thoughtfully placed ADU. Common reasons our Grimes clients reach out include:
- Housing aging parents close by while keeping everyone independent.
- Creating a private space for adult children or guests.
- Earning rental income in a high demand growth corridor.
- Adding lasting value to a property in an appreciating market.

The SF-592 By-Right Law
Iowa made building an ADU much simpler. Under the state law known as SF-592, ADUs are now allowed by right in every city and county in Iowa, including Grimes. That means you no longer need special approval just to be allowed to build one. Setback requirements still apply, so your ADU must sit a certain distance from property lines, but the days of fighting for permission are largely behind you. You can read more about how ADUs support housing options through the U.S. Department of Housing and Urban Development.
As a local ADU builder Grimes homeowners turn to, we make sure your design respects setbacks and local rules from day one, so there are no surprises down the road.
Permit Timeline and Cost
One of the most reassuring parts of building in Iowa is how straightforward the permit process can be. An ADU building permit in Iowa typically takes about 3 days to 2 weeks to be issued. Costs are modest too, usually ranging from a few hundred dollars up to a couple thousand dollars depending on the city. We handle the application details for you, which keeps the process smooth and stress free.
