Understanding Additional Dwelling Units (ADUs)
Northern Colorado is buzzing with fresh ideas about how and where to live. For many, the additional dwelling unit stands out as the most flexible path. An ADU gives you options—host your parents, rent to a student, or carve out a home office—all on your property. These structures fit right into our neighborhoods, adding value and comfort while keeping family, flexibility, and smart investments at the core.
Common Types of Additional Dwelling Units in Colorado
In Fort Collins, Loveland, and Greeley, homeowners have a variety of ways to add an ADU. The most popular types bring their own benefits and style:
- Detached ADUs A detached ADU is a stand-alone small home in your backyard. Think of a snug cottage, modern studio, or tiny home. These units feel like a private getaway, perfect for renters, aging parents, or young adults starting out. Detached ADUs give the main house its space, while the new unit enjoys its own entrance, yard, and utilities.
- Attached ADUs Rather than building a separate structure, an attached ADU connects directly to your main home. Space is smartly added on, either to the side, back, or even over a garage. This makes an attached unit great for smaller lots or tighter budgets. Family members can stay close but still enjoy privacy.
- Garage Conversions Many Colorado homes have spacious garages just waiting to be transformed. By converting a garage into an additional dwelling unit, homeowners tap into space that’s already there. These units are cozy, cost-effective, and can be upgraded with energy-saving options like the passive house standard.
- Basement ADUs Basement spaces often sit idle except for storage or the occasional workout. When finished as an ADU, they bring new life to unused square footage. Basement ADUs are popular for home remodel projects since they typically require less exterior work. They make ideal rentals or living quarters for family.
Each ADU type offers its own inspiration, which custom home builders or a design & build expert can turn into a dream project.
Why Northern Colorado Homeowners Choose ADUs
People in Northern Colorado don’t just see ADUs as extra space. They see solutions to real needs. Here’s what drives homeowners to build:
- Extra Income Renting out an ADU is one of the fastest ways to boost your monthly earnings. With university students in Fort Collins and a growing rental market across Loveland and Greeley, many homeowners see steady demand.
- Family Flexibility Multi-generational living is back. An additional dwelling unit gives you breathing room when family visits, provides a safe spot for aging parents, or supports adult kids who aren’t ready for their own house just yet.
- Increasing Property Value Building an ADU is a smart move for future resale. Home buyers are drawn to houses with income-ready spaces, flexible layouts, and modern updates from trusted home builders in Northern Colorado.
- Supporting Local Housing ADUs help ease the housing crunch. By adding affordable, attractive units in established neighborhoods, homeowners support local growth and provide options for people who want to stay in their community.

- Set Clear Timelines Custom home builder teams will lay out a basic schedule, but delays can crop up. Plan extra weeks for permit review, utility connections, or bad weather.
- Stay in Close Contact with Contractors Frequent updates keep surprises to a minimum. Create a shared calendar or use a project app to check progress, share documents, and ask questions.
- Anticipate Common Delays Some delays are out of your hands, like city inspection backlogs, utility company schedules, or material shortages. Stay flexible and talk with your builder about workarounds if timing shifts.
