Accessory dwelling units (ADUs) offer an incredible opportunity to expand your living space without changing your address. These versatile structures provide the extra square footage you crave while adding significant value to your property.
For homeowners in Denver, Highlands Ranch, and Littleton, an ADU represents more than just a construction project. It represents a lifestyle upgrade. Below, our beginner’s guide to accessory dwelling units will explain to homeowners the types of ADUs, their benefits, regulations in Denver, and more.
Understanding the Accessory Dwelling Unit
An ADU is a secondary residential unit on the same lot as a primary single-family home. Others may also refer to these structures as granny flats, carriage houses, or backyard cottages. Regardless of the name, they all provide an independent living area with a kitchen, bathroom, and sleeping quarters. Unlike a simple room addition, an ADU functions as a fully self-sufficient home.
Types of ADUs
There are three primary categories of ADUs you can consider for your property. The first and often most desirable option is a detached ADU. This is a standalone structure built separately from the main house, usually in the backyard or above a detached garage. This option provides the greatest privacy for both the primary homeowners and the unit’s occupants.
The second option is an attached ADU. This structure connects directly to the main house, sharing a wall. This is an excellent choice if you have ample side yard space or want to build an addition that functions independently from the rest of the home.
Finally, there are also internal ADUs. These ADUs involve converting an existing space within your home, such as a basement or an attic, into a separate living unit. This is a very cost-effective route, as the structure already exists and requires only interior renovations to meet code and comfort standards.
Unlocking the Benefits for Denver Homeowners
Building an ADU is a significant investment, but it offers substantial returns. Building an ADU or transforming a part of your home into an ADU can boost your property value, serve as an additional source of income, and make your property more habitable for multi-generational living.
Property Value
The most immediate benefit of an ADU is the increase in your property value. In the competitive Denver real estate market, homes with ADUs are highly sought after. They offer a unique level of versatility that standard single-family homes cannot match. By adding legal, livable square footage, you instantly boost your property’s equity.
Income Source
Beyond equity, an ADU serves as a powerful income generator. The demand for rental housing in Denver and many popular home markets continues to rise, and a well-designed carriage house or basement apartment can provide a steady stream of passive income. This financial boost can help offset mortgage payments or fund other lifestyle goals.
Multi-generational Living
For many of our clients at A2Z Builders, the primary motivation is family. We specialize in family-focused designs because we understand that life changes. An ADU offers the perfect solution for multi-generational living. It provides a safe, accessible home for aging parents who want to maintain their independence while staying close to their grandchildren.
Conversely, it can serve as a launchpad for recent college graduates returning home who need their own space. It can even transform into a dedicated home office, an art studio, or a guest suite for visiting friends. The flexibility this space provides allows your home to adapt to your needs rather than forcing you to adapt to your home.
Navigating Regulations and Zoning in Denver
One of the first questions homeowners ask involves the legality and logistics of building an ADU. The city of Denver recognizes the need for diverse housing options and has taken steps to make ADUs more accessible, but navigating the zoning code remains complex. Generally, the city considers lot size, the structure’s position on the lot, and building height when approving permits. There are strict guidelines regarding how much of their backyard homeowners can cover with structures to maintain the character and openness of neighborhoods.
Securing the necessary permits is a critical step in the process. This involves submitting architectural plans that comply with all local building codes, safety standards, and zoning laws. While this might sound daunting, working with an experienced partner makes all the difference. At A2Z Builders, we handle the complexities of the permitting process for you.
Designing a Space That Fits Your Life
Designing an ADU is an exciting, creative challenge. Because these units are typically smaller than a standard home, every square inch matters. Smart and careful design creates a space that feels open, airy, and functional.
ADU Aesthetic Design Considerations
Aesthetics play a huge role in the success of your project. A well-designed ADU should not look like an afterthought. It should complement your existing home’s architecture and blend seamlessly with your landscape.
At A2Z Builders, our goal is to create a cohesive look that enhances your property’s overall appeal. We consider exterior materials, rooflines, and window styles that echo the character of your main house while giving the ADU its own distinct charm.
ADU Functionality Considerations
Practicality is just as important as beauty. We work with you to understand precisely how you want to use the space.
If it is for an aging parent, we prioritize accessibility features like no-step entries and wider doorways. For rentals, we focus on durable finishes and low-maintenance materials. By tailoring the design to your specific needs, we ensure the final result is a perfect fit for your family.
Construction and Costs
With a final design and approved permits in hand, construction can begin. Choosing the right builder is key to a smooth building process and high-quality results. With over 16 years of experience as house building contractors, A2Z Builders delivers premium craftsmanship using top-quality materials that stand the test of time. We prioritize transparency, quality, and communication to make your journey as seamless as possible.
Cost and timeline are critical factors in any project. ADU pricing varies by size, type, and finishes, with detached new construction typically costing more than basement conversions due to the foundation, framing, and utility connections. To keep you informed, we provide detailed estimates upfront, so you know exactly where your budget is going. Throughout the build, we update you at every step so there are no surprises.
