Denver ADU Builder & Custom Residential Construction

Thoughtfully Built Spaces Designed for the Way You Live

Denver's ADU Specialists

At L&D Construction, we specialize in Accessory Dwelling Units (ADUs), custom homes, and residential construction projects throughout metro Denver. With more than 70 ADUs completed across the city, we understand the unique zoning, permitting, and construction considerations that come with building in Denver's established neighborhoods.

What is an Accessory Dwelling UNit?

You may have heard ADUs called by many different names, including carriage houses, backyard cottages, granny flats, in-law suites, casitas, garden suites, garage apartments, or secondary dwelling units. Regardless of the name, an ADU is a smaller, independent residential living space located on the same property as a primary home. These versatile structures are becoming increasingly popular as homeowners look for ways to maximize their property's potential while creating flexible living options.

The possibilities are endless

Whether you're creating space for aging parents, generating rental income, accommodating multigenerational living, building a home office, or planning for future flexibility, an ADU can provide a smart long-term solution. Our team helps homeowners navigate every phase of the process, from feasibility and design through permitting and construction, with thoughtful planning, clear communication, and quality craftsmanship built to last.

Paving the way in alternative housing solutions

As Denver continues to address housing needs and neighborhood growth, the city has expanded opportunities for homeowners interested in building ADUs. Recent zoning changes have made it possible for more property owners to add secondary living spaces than ever before, creating new opportunities for families and investors alike.

Built on Relationships

"L&D helped elevate then design of our ADU through smart details that aligned with code requirements and practical refinements that made a real difference. We had complete trust in L&D to get the build right, and they followed through by meeting their timeline, communicating clearly, and being responsive whenever questions or changes came up. Their input on functional touches improved how the space actually works day to day, adding flexibility without overcomplicating anything.

What we appreciated most was their ability to think through how the space would be used over time. The finished ADU feels efficient, adaptable, and well executed. We’re extremely happy with the result and would confidently recommend L&D to anyone considering an ADU."
