The Charlotte market
Charlotte does not issue its own trade permits: Mecklenburg County Code Enforcement (part of LUESA) does, and it requires separate permits for building, electrical, heating, air conditioning and plumbing work. NC-licensed trade contractors get instant online permits through Trade Internet Permitting, and the plumbing contractor is the primary contractor for electric water heater change-outs. Owner-occupants may pull homeowner permits only if they personally do the work, and trade work not tied to a building permit must be submitted in person. Fees sit in the LUESA Fee Ordinance, which could not be retrieved; sub-permits for equipment change-outs on one- and two-family homes are charged at 50% of the primary trade fee. Contractors can request inspections as soon as work is done. Heat pumps are common here, providing main heat in 38% of North Carolina homes per EIA. Concord, Gastonia and the South Carolina counties use other offices.
Gas heats water in only 22% of North Carolina homes, so a gas tankless unit often means a new gas line, and an electric tankless unit means a big circuit. Either way the job reaches beyond plumbing. Ask the installer to list the gas or electrical work as separate items so the heater price stays clear. Then ask what flow rate the unit delivers in winter, when the water coming in from the street is colder.
