Housing and Building Standards North Carolina 3 Minutes Read ยท published March 01, 2026 Flag of North Carolina

In Concord, North Carolina builders adding an accessory dwelling unit (ADU) must meet local permitting and the applicable building and energy codes at plan review and inspection. This guide summarizes the permitting pathway, typical energy-related checklist items, enforcement contacts, and practical steps to prepare an ADU for approval under the city and state building regimes. It is intended for contractors, architects, and developers working in Concord who need to align construction and energy compliance before permit issuance and final inspection.

Overview of ADU Energy Requirements

ADU projects in Concord are reviewed under the local permitting process and applicable state building codes for energy efficiency. Energy compliance generally includes insulation, HVAC equipment sizing and efficiency, fenestration U-values, and verified blower-door or duct testing when required by the controlling energy standard at plan review and inspection. Specific testing or prescriptive requirements depend on the edition of the State Building Code and any local amendments applied at the time of permitting. For local permitting and inspection procedures contact the Building Inspections Division City of Concord Building Inspections[1].

Key Steps for Builders

  1. Confirm applicable code edition and energy standard early with the Building Inspections plan review team.
  2. Prepare energy compliance documentation: REScheck/COMcheck or equivalent forms, mechanical schedules, insulation specs, and window ratings.
  3. Coordinate HVAC sizing and installation to match energy calculations and include combustion safety where applicable.
  4. Schedule required inspections (insulation, HVAC, blower door, final) through the City of Concord permit portal or inspection line.
  5. Retain test reports and field verification documents for final approval.
Confirm the edition of the State Building Code referenced on your permit before submitting energy compliance documents.
