Elevate Your Living Space with a Custom ADU
At Melton, we specialize in crafting exquisite living spaces that enhance the everyday and bring joy to the process. 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.
Common Questions About ADUs
How big can my ADU be?
According to the City of Boulder, attached ADUs can be up to 1,000 sq. ft. or half the size of the main house, whichever is smaller. Detached ADUs can be up to 800 sq. ft. Affordable ADUs and those associated with a designated historic property can take advantage of additional incentives such as larger size limits and reduced parking requirements.
Can I rent out my ADU?
Yes, ADUs can be rented out, providing a great opportunity for additional income. However, regulations vary, so we’ll guide you through any specific requirements.
What is the process for getting an ADU approved?
The process involves determining your zoning district and lot size, designing your ADU according to city guidelines, and submitting a detailed building permit application. We assist you at every step to ensure compliance and a smooth approval process.
Are there any special requirements for ADUs in historic districts?
Yes, properties in designated historic districts or those with individual landmark status may have different size limits and reduced parking requirements. We can help navigate these additional guidelines to ensure your ADU meets all necessary criteria.

FAQ: About ADUs in Colorado
Q: What does Colorado’s new ADU legislation mean for homeowners?
Recent statewide legislation, including HB 24-1152, supports homeowners who want to build Accessory Dwelling Units by reducing local restrictions and streamlining approvals. For Boulder County residents, this means it is easier to create legal, long-term housing options on your property. The new law encourages gentle density while maintaining neighborhood character, making ADUs a powerful tool for addressing Colorado’s housing shortage.
Q: How does an ADU increase property value?
An ADU adds functional living space that can serve as a rental, a home office, or a private suite for family. Because it offers flexible use and potential rental income, an ADU typically raises a home’s appraised value and resale appeal. In markets like Boulder, where buildable land is limited, an ADU can make a property stand out to both buyers and investors.
Q: What are the key design considerations for a successful ADU?
A great ADU balances independence with connection. This can include a full kitchen and bathroom, comfortable living areas, and plenty of natural light. Good design also ensures privacy between the main home and the ADU through thoughtful orientation, landscaping, and sound insulation. Energy efficiency, low-maintenance materials, and flexible layouts can make the unit more comfortable and sustainable.
Q: What are Boulder’s zoning rules for ADUs?
Most residential zones in Boulder allow one ADU per lot, but the specifics depend on lot size and location. Some neighborhoods have additional requirements for parking, setbacks, and building height, especially in historic districts. Working with an experienced design-build firm ensures your project aligns with local code from the start.
Q: Can I rent out my ADU in Boulder?
Yes. Homeowners are allowed to rent ADUs for long-term housing, and doing so can help offset mortgage costs while contributing to Boulder’s housing supply. Short-term rentals may be restricted based on zoning and licensing rules. We’ll review your options early in the process to ensure ccode ompliance and maximize value.
