What a building permit costs in North Carolina
Two parts: the local permit fee, and from 2027 the state fee on top of it.
The local fee is set by the city or county that issues the permit, and it's most of the cost. Offices price homes mostly by square footage and commercial work by construction cost, and they differ on trade work: Wake County issues one permit per residential project that covers all the trades, while Greensboro has each licensed contractor pay for their own electrical, mechanical or plumbing permit. Most offices also charge for plan review and re-inspections, and double the fee when work starts before the permit is issued.
The state fee is new. Session Law 2026-41 adds a State Building Code regulatory fee (G.S. 95-281) to every building permit issued from January 1, 2027: $100 for buildings under the NC Building Code, $25 under the NC Residential Code, and $10 for other work. The permit office collects it with its own fees and sends it to the state Department of Labor each quarter. What the new fee adds up to for contractors.

Work that doesn't need a permit: the $40,000 rule
G.S. 160D-1110(c) exempts a lot of smaller work from building permits, and so from both fees.
In North Carolina, construction, repair or alteration costing $40,000 or less in a single-family home, farm building or commercial building doesn't need a building permit, as long as it's done to the State Building Code, unless it involves any of these:
- Adding, repairing or replacing load-bearing structures. Replacing windows, doors, siding, and porch or deck pickets, railings, stair treads and decking is still exempt.
- Adding or changing the design of plumbing. Replacements that don't change size or capacity are exempt.
- Adding, replacing or redesigning heating, air-conditioning or electrical wiring, devices or equipment, other than like-for-like electrical devices and light fixtures.
- Materials the State Building Code doesn't allow.
- Adding roofing. Replacing a roof is exempt.
- Anything the NC Fire Code covers.
Separate trade permits still apply to most HVAC, electrical and plumbing work, and a city or county can't require more than one building permit for a gas or electrical appliance replacement by a licensed contractor (G.S. 160D-1110(d)).

Permit fees: common questions
- How much does a building permit cost in North Carolina?
- Each city or county permit office sets its own fees, usually by square footage for homes and by construction cost for commercial work, and some charge for electrical, mechanical and plumbing permits separately. From January 1, 2027, every building permit also carries a state fee on top: $100 for work under the NC Building Code, $25 under the NC Residential Code, and $10 for other work.
- Is there a state building permit fee calculator for North Carolina?
- The state doesn't publish one, because local fees differ by office. This page calculates the new state fee for a job or a year of permits, and links to each permit office's own fee schedule or calculator for the local part.
- What is the NC State Building Code regulatory fee?
- A fee created by the 2026 state budget (Session Law 2026-41) in G.S. 95-281. Local governments collect it with each building permit, in addition to their own fees, and send it to the Department of Labor every quarter. It pays for the new Building Codes and Interpretations Bureau, which runs the Building Code Council and Residential Code Council.
- When does the new state permit fee start?
- January 1, 2027. It applies to permits issued from that date; permits issued before it don't carry the fee.
- Who pays the state permit fee?
- The law says each building permit applicant pays it: usually the contractor, or the homeowner who pulls their own permit. The permit office collects it with its own fees.
- Are trade permits charged $10 or $25?
- Not settled yet. A stand-alone electrical, mechanical or plumbing permit reads most naturally as "other work" at $10, which is how this calculator counts it by default. An office could instead count a trade permit on a new house or commercial building as part of that building, at $25 or $100. The calculator lets you price it either way.
- Do I need a building permit for work under $40,000 in North Carolina?
- Often not. Under G.S. 160D-1110(c), work costing $40,000 or less in a single-family home, farm building or commercial building doesn't need a building permit, unless it adds, repairs or replaces load-bearing structures, adds or redesigns plumbing, adds, replaces or redesigns heating, air-conditioning or electrical systems (other than like-for-like fixtures and devices), uses materials the code doesn't allow, adds roofing (replacing a roof is exempt), or involves the Fire Code.
