BUILDING ADUs IN CENTENNIAL
Centennial is a suburban community in Arapahoe County known for its larger lot sizes and family-oriented neighborhoods. As HB24-1152 takes full effect, Centennial homeowners now have the green light to build ADUs on their properties.
Growing ADU interest in Centennial is driven by homeowners looking for rental income, multigenerational living solutions, and long-term property value increases. The city's larger lots — especially in established neighborhoods — provide ample space for detached backyard ADUs.

TYPES OF ADUs IN CENTENNIAL
Centennial's larger suburban lots are ideal for detached backyard ADUs, which offer the highest rental value and most privacy. Many homes also have full basements suitable for conversion. Attached additions work well for properties with limited yard space.
