Smarter Living Starts with Accessory Dwelling Unit Service

At Empirical Construction we help homeowners find smarter ways to live, earn, and grow their family space. Accessory dwelling units (ADUs) make it easy to add value to your home, whether you're welcoming in-laws, earning rental income, or creating room for a growing family. Our team handles everything from planning to final build, making the process smooth and stress-free.

What is an Accessory Dwelling Unit (ADU)?

An accessory dwelling unit (ADU) is a smaller, independent residential structure located on the same lot as a primary single-family home. It includes essential living features like a kitchen, bathroom, and sleeping area, making it a fully functional secondary dwelling unit. ADUs come in many forms, such as detached backyard cottages, attached suites, garage conversions, or even basement apartments.

While the concept may sound simple, building an ADU unit requires careful planning, design, and permitting. That’s why working with a local ADU contractor near me is crucial. A contractor who understands your city’s zoning laws, permit processes, and building codes can help you avoid delays, ensure compliance, and bring your project to life efficiently and legally.

What You Need to Know About ADU?

An accessory dwelling unit is a small, self-contained home located on the same lot as a single-family home. Also known as in-law units, accessory apartments, or secondary units, ADUs typically include a kitchen, bathroom, and a sleeping area. They can be attached to the main house, detached in the backyard, or even built over a garage.

These compact homes are ideal for relatives, tenants, or aging parents. With options like Junior Accessory Dwelling Units and manufactured homes, they make excellent use of your existing property without the cost of a full home addition. If you are searching for home addition contractors near me, it is worth exploring if an ADU is the right fit for your space.

Why Denver Homeowners Are Adding Accessory Dwelling Units?

As housing prices rise and space becomes more valuable, ADU housing is gaining momentum across Denver. The city’s Plus One ADU Program and recent changes in zoning code and building code requirements have made it easier for homeowners to add accessory dwelling units to their lots.

According to the National Association of Home Builders, homes with ADUs can increase property value by up to 35%. That’s because these units help offset mortgage payments, support multigenerational families, and offer flexible space for work or guests.

However, navigating zoning regulations, building permits, and building and safety requirements is not an easy task. That’s why working with a local ADU contractor near me, like Empirical Construction, ensures your project meets every standard, especially the California Building Code updates adopted by Denver's Department of Building and Safety.
