The Raleigh market
The City of Raleigh lists replacing existing equipment, such as a water heater or HVAC unit, among projects that need a permit but no plans; installing new equipment requires a plot plan. The FY27 fee guide sets a $124 minimum trade permit fee per trade and applies it to any fee not separately listed, which likely covers a stand-alone replacement. A homeowner acting as their own contractor can use the Owner Exemption Affidavit, which covers building, electrical, mechanical and plumbing, but must occupy the home for 12 months afterward and attend every required inspection. Otherwise an NC-licensed contractor pulls the permit. DOE puts Wake County in mixed-humid climate zone 4A, and EIA's 2020 survey found 62% of North Carolina homes heat with electricity and 38% with a central heat pump.
About 84% of North Carolina homes have central air, and zone 4A summers are long and humid. Ask whether your current outdoor unit is a heat pump. Many local systems are, and replacing one with an AC-only unit means losing heat. An oversized unit cools fast and leaves rooms clammy, so ask for a load calculation and a matched coil.
