In today’s competitive real estate market, homeowners are increasingly turning to Accessory Dwelling Units (ADUs) as a smart way to boost property value, generate rental income, and create flexible living spaces.

Whether you’re in Denver, Boulder, Fort Collins, or anywhere in the Colorado Front Range, our team of architects, engineers, and builders is here to guide you through every step of the process.

What Are Accessory Dwelling Units (ADUs)?

An Accessory Dwelling Unit (ADU) is a secondary, self-contained living space located on the same property as a primary residence.

These compact yet complete homes include their own entrance, kitchen, bathroom, and sleeping areas, making them ideal for a variety of uses. Commonly referred to as granny flats, in-law units, or backyard cottages, ADUs are versatile and practical solutions for homeowners looking to maximize their property’s potential.

Why Build an ADU?

Adding an ADU to your property offers a wide range of benefits, making it a worthwhile investment for homeowners in the Colorado Front Range.

1. Increase Property Value: ADUs can boost your property value by 20-30% on average. These units are highly desirable for buyers, offering additional living space and income potential.

2. Generate Rental Income: ADUs are an excellent source of passive income. Many homeowners rent out their ADUs to long-term tenants or as short-term vacation rentals, often earning enough to offset mortgage payments or other expenses.

3. Flexible Living Solutions: ADUs provide versatile housing options for:

  • Aging parents or in-laws (multigenerational living)
  • Adult children transitioning to independence
  • Guests or extended family members
  • Home offices or creative studios

4. Sustainable and Efficient Land Use: ADUs make efficient use of existing residential land, reducing urban sprawl and preserving green spaces. Their smaller size also means lower energy consumption, making them an eco-friendly housing option.

The ADU Construction Process: Colorado ADU builder's Approach

Building an ADU can feel overwhelming, but with Level Design Build, the process is straightforward and stress-free. Here’s how we bring your ADU vision to life:

Step 1: Initial Consultation

We’ll discuss your goals, budget, and property specifics to determine the best approach for your ADU.

Step 2: Design and Planning

Our in-house design team will create a custom plan that maximizes space, functionality, and aesthetics while adhering to local regulations.

Step 3: Permitting

We’ll handle all the necessary permits and approvals, navigating the complexities of local zoning laws on your behalf.

Step 4: Construction

Our skilled builders will bring your ADU to life, ensuring high-quality craftsmanship and attention to detail.

Step 5: Final Inspection and Handover

Once construction is complete, we’ll ensure your ADU meets all safety and quality standards before handing over the keys.

As contractors, we work closely with our engineers to ensure that the project’s design and structural requirements align perfectly with the building process.

Our engineering team ensures that all aspects of the renovation meet local, state, and federal regulations, while our contractors ensure these requirements are implemented on-site. Whether you’re concerned about fire safety, ADA compliance, or other legal requirements, we’ve got you covered.

Customer Reviews

Great experience with The Level team! They were on time, responsive, professional and got it done. They did great work and were finished on time. Would definitely recommend to anyone looking for this type of work.
Eric Corff
Level Design Build helped stabilize my deck supports which were failing due to erosion on a steep slope. We worked with Level Engineering to do the initial inspection and to draw the structural plans. Level Design Build then worked with our structural engineer to make changes to the plans to help make the final design more affordable and constructible.
Will St. Charles​

The LDB Difference

Comprehensive In-House Expertise: Unlike other firms, we offer in-house architectural, civil, and structural design services. This means quicker turnaround times, seamless coordination, and unparalleled attention to detail throughout every phase of your project.

Personal touch: Most general contractors are “paper GCs,” meaning that they subcontract all of the actual work out to other, unaffiliated entities and make their money on the mark up of those subcontracts and project management/oversight, costing you more money and headache. Our in-house team allows us to better control quality, construction costs, and schedule.

Access to Top Talent: As a part of the Level family, we’re backed by a team of over 50 architects and engineers from our sister company, Level Engineering and Inspections. With this wealth of expertise at our disposal, we ensure that every aspect of your project is meticulously planned and executed to perfection.

Flexibility and Agility: Our rare blend of experience and capabilities allows us to move swiftly and adapt to changing needs. Whether it’s making design changes on the fly or navigating complex permitting and compliance requirements, we’re equipped to handle it all with ease.

The Perfect Size: We’re big enough to tackle complex, challenging projects, yet small enough to offer personalized attention and competitive pricing. No matter the size or scope of your project, you can trust us to deliver exceptional results.
