Considering the prospect of constructing an Accessory Dwelling Unit (ADU)? If you’re intrigued by the idea but have lingering questions about cost, timing, and square footage, you’re not alone. Let’s delve into these three frequently asked questions to provide you with clear insights.
1. How much does an ADU cost?
The cost of an ADU can vary depending on various factors, but let’s talk specifics. At Tiny Homes of Iowa, our pricing starts at an affordable $111,000 for a one-bedroom, one-bathroom unit. Need more space? We offer larger one bedroom and two-bedroom options starting at $150,000 and $188,000, respecctively. These prices encompass everything from site preparation to permits and final inspection, along with the fully installed unit complete with fixtures and appliances. Even ground preparation and foundation work are part of the package. For planning purposes, you can estimate around $250 per square foot to build a custom tiny home.
Following installation, it’s essential to consider additional fees such as home insurance and property taxes. The good news? Your primary home won’t undergo reassessment. Your property tax will be recalculated based on a blended assessment, resulting in a minimal annual increase, typically around 1 percent of the ADU’s value, while the base value of your existing primary dwelling remains unchanged.
2. What’s the maximum size for an ADU?
The maximum allowable size for an accessory dwelling unit varies by municipality in Iowa, each with its own regulations. For example, in Des Moines, one-bedroom ADUs can be up to 576 square feet, but not exceed 50% of the floor area of the primary house. In Johnston, the maximum size for a tiny home is capped at 1,600 square feet for a lot less than 1 acre.
Regulations can differ significantly between cities, but don’t worry. We’ve compiled regulations for numerous Iowa cities, or you can visit the Polk County Housing Trust Fund for additional info and specifics in your area. With our flexible floor plan options, many types of properties can accommodate a detached ADU, ensuring a tailored fit for various backyards.
3. How long does it take to build an ADU?
Thanks to regulatory changes over the last few years, the timeline for ADU construction has significantly shortened. The initial step involves obtaining approval from the local planning department, a process typically completed within 60 days. Following approval, our average build takes approximately six months to finish. Of course, individual project timelines may vary based on location and project scope.
