BUILDING ADUs IN HIGHLANDS RANCH
Highlands Ranch is an unincorporated community in Douglas County known for its master-planned neighborhoods, large lots, and high-income demographics. While Highlands Ranch is HOA-heavy, Colorado's HB24-1152 prohibits HOAs from banning ADU construction outright — they can apply reasonable design standards but cannot stop you from building.
ADU demand in Highlands Ranch is driven primarily by multigenerational living — parents building units for aging family members or adult children. The community's large lot sizes are well-suited to detached backyard ADUs that maintain privacy and property aesthetics.
303 Construction has experience building in Douglas County and navigating HOA design requirements. We ensure your ADU meets both county building codes and HOA architectural standards while maximizing your investment.
TYPES OF ADUs IN HIGHLANDS RANCH
Highlands Ranch's large lots are ideal for detached backyard ADUs. Many homes also have full basements suitable for conversion. HOAs can set design standards but cannot prohibit ADU construction under HB24-1152. Attached additions work well for maintaining seamless property aesthetics.
