- All-in cost ranges for detached, attached, and garage-conversion ADUs across Charlotte, the Triangle, the Triad, coastal NC, and the mountains.
- Municipal ADU rules — Charlotte's allowance, Raleigh's pilot program, and the home-rule landscape elsewhere.
- Line-item breakdown: design, permits, site work, foundation, framing, MEP, finishes, utility upgrades.
- Coastal wind-zone requirements where applicable.
- Realistic schedules — including the rapid-growth-metro permit-office bottlenecks.
- Red flags in contractor bids and the questions that separate a real number from a placeholder.
- Financing options homeowners actually qualify for — HELOC, cash-out refi, NC-specific programs.
Sample insight
Detached new-construction ADUs in North Carolina typically run $180–$320 per square foot all-in in 2026, with Charlotte and the Triangle commonly $220–$380 once rapid-growth-metro permit-office timelines and labor competition are accounted for. Most homeowners under-budget by 12–20% due to overlooked utility upgrades and the multi-week metro permit reality. (Estimate based on 2024–2025 North Carolina permit and bid data.)
