04 / ADUs

A second home,
in your backyard.

North Carolina’s 2025 ADU rules opened doors. We build detached cottages, in-law suites, and rental units that meet code, look like they belong, and start earning back from day one.

Design concept — a detached backyard cottage ADU at golden hour, similar to the ADUs we build

Four reasons our clients build them.

01

Rental income

Camp Lejeune's housing demand never stops. A 600 sq ft ADU can rent $1,200–$1,800/mo. Pays itself off in 6-10 years.

02

Aging parents

A separate door, private kitchen, no stairs. Family close but not in your living room.

03

Adult child returning

Or pre-empting their return. Privacy on both sides; built-in for the next chapter.

04

Home office

A real one. With a real wall between you and the rest of the household.
