ADU costs in the Triangle vary depending on the type of build and site conditions. A garage conversion is usually the most affordable option, typically ranging from $60,000 to $130,000 since the existing structure reduces new construction. A detached ADU built from the ground up often ranges from $180,000 to $300,000+, depending on size, utilities, site work, and finish level. Above-garage ADUs typically start around $120,000+, particularly if structural reinforcement is required. These ranges reflect typical material and labor costs in the Raleigh–Cary area, but every property is different. The best way to determine an accurate cost is through a consultation with our team.
