FAQ

What is an ADU?

An ADU, or accessory dwelling unit, is a self-contained living space on the same property as a single-family home. It can be attached, detached, a garage conversion, or even an internal unit like a basement suite.

How much does it cost to build an ADU in my backyard?

The cost of building an ADU in your backyard depends on size, design, permits, and features like bathrooms or kitchens. Backyard ADUs and custom units typically start in the low six figures.

Can I convert my garage into an ADU?

Yes — garage conversions are a popular and cost-effective way to add an ADU. Whether it's a 2-car garage ADU conversion or a detached garage, we handle everything from design to permitting.

What types of ADUs do you build?

We build all ADU types: attached, detached, junior ADUs, internal units, and garage conversions. Whether you're looking for a one-bedroom ADU or something compact like a small ADU, we’ve got you covered.

Do ADUs add value to my home?

Yes — a well-designed ADU adds significant value, whether you're looking to generate rental income, house family, or boost resale value. They’re a smart long-term investment.

How long does it take to build an ADU?

Most ADUs take 4–9 months from start to finish depending on the type (e.g., attached ADU vs. garage conversion) and the permit process in your city.

What are the ADU regulations in Colorado?

Before you start, it’s crucial to understand the local rules for accessory dwelling units. Colorado’s Department of Local Affairs (DOLA) provides a comprehensive guide outlining requirements for zoning, permitting, size limits, and utility connections for ADUs.
