Accessory Dwelling Units

Elevate Your Living Space with a Custom ADU

At Melton Design Build, we specialize in crafting exquisite living spaces that enhance your lifestyle and add value to your property. With the passing of Colorado HB 24-1152, which supports the construction of Accessory Dwelling Units (ADUs), there’s never been a better time to consider adding an ADU to your Boulder home. These versatile units not only provide additional living space but also reflect a forward-thinking approach to modern living.

What is an ADU?

ADUs are compact, fully equipped living units located on the same lot as a primary residence. Also known as in-law suites, casitas, or carriage houses, they can be internal (like a basement apartment), attached (such as a converted garage), or detached (a standalone building). These units are perfect for expanding your living space, accommodating guests, or creating a private retreat. Learn more about ADUs and their configurations at Accessory Dwellings, a comprehensive resource for everything related to accessory dwelling units.

Why Build an ADU?

Enhanced Property Value: ADUs are an excellent investment, significantly boosting the value of your property with high-quality, additional living space.

Luxury Living: Whether it’s a guest house, a private office, or a space for your hobbies, an ADU offers the luxury of extra space tailored to your needs.

Sustainable Solutions: Building an ADU is a step towards sustainable living. These units are typically smaller and more energy-efficient, aligning with eco-friendly practices.

Versatile Space: ADUs offer flexible living arrangements, perfect for hosting family and friends, creating a serene workspace, or enjoying a personal sanctuary.

Aging in Place: ADUs are an ideal solution for aging in place, allowing homeowners to live comfortably in their own homes as they age. This approach provides a safe, accessible living environment for seniors while maintaining their independence. “People love their communities and neighborhoods,” says Shannon Guzman, senior strategic policy adviser at AARP. “Moving to a more affordable location can take them away from the people and places that enrich their lives. We have to rethink housing and find better solutions, like ADUs.”

Navigating Boulder’s Permitting Process

Building an ADU in Boulder requires careful navigation of local building codes and zoning regulations. The City of Boulder has long focused on the importance of allowing more ADUs to address housing needs. By increasing the saturation limit from 10% to 20% in 2019 and then removing it entirely in 2023, Boulder has made it easier for homeowners to add ADUs. These changes reduce market pressure, provide affordable housing options, and offer homeowners rental income opportunities. Boulder also provides a path for certifying existing illegal ADUs, which involves meeting current land use code standards and obtaining the necessary building permits to legalize the unit. These changes support higher density and better utilization of available space, addressing the city’s housing density problem, as Boulder cannot expand upwards and must focus on infill development​.

As Boulder’s premier design-build firm, we have a deep understanding of the local permitting process and established relationships with local authorities, ensuring a smooth, hassle-free experience for your ADU project.
