Does North Carolina's $40,000 permit exemption apply to your project?
Under North Carolina General Statute 160D-1110(c), no building permit is required for work costing $40,000 or less on a single-family residence, farm building, or commercial building, as long as it does not add or redesign load-bearing structure, plumbing, HVAC, or electrical systems, add new roofing, use materials the code does not allow, or trigger the North Carolina Fire Code. Like-for-like replacement generally stays exempt. The work must still meet the North Carolina State Building Code.

Often exempt
- Interior painting, finishes, and cosmetic updates
- Flooring and tile that is not structural
- Cabinet and countertop replacement

Not covered by this exemption
- Adding, repairing, or replacing load-bearing structure
- Adding plumbing or changing its design, size, or capacity
- Adding or redesigning HVAC or electrical wiring, devices, or equipment
- Adding new roofing (beyond replacing an existing roof)
- Materials the North Carolina State Building Code does not allow
- Any work the North Carolina Fire Code applies to
- Any project costing $40,000 or more
- Duplexes, townhouses, and other multifamily buildings (not named in this exemption)
Falling outside this exemption does not always mean a permit is required for every item, and falling inside it never removes the building code. Like-for-like replacement is generally still exempt, while additions and design changes are not. Because local rules vary, confirm the specific work with your city or county permitting department.
Frequently asked questions
- Does the $40,000 exemption mean I never need a permit for work under $40,000?
- No. The exemption is limited. It waives the state building permit for work costing $40,000 or less on a single-family residence, farm building, or commercial building, but only when the work does not add or redesign load-bearing structure, plumbing, HVAC, or electrical systems, add new roofing, use materials the code does not allow, or trigger the North Carolina Fire Code. Like-for-like replacement is generally still exempt; additions and design changes are not.
- Does the exemption cover duplexes or townhouses?
- The N.C.G.S. 160D-1110(c) exemption names a single-family residence, farm building, or commercial building. It does not list two-family dwellings (duplexes) or townhouses, so do not rely on it for those. Confirm with your local permitting department.
- If I am exempt from the permit, am I exempt from the building code?
- No. The exemption removes the permit, not the code. The work must still be done in accordance with the current North Carolina State Building Code, and licensed-trade requirements can still apply.
- Is roof replacement covered?
- Replacing an existing roof (a re-roof) is generally exempt under the $40,000 rule, along with a small portion of roof deck. Adding new roofing where there was none is a carve-out that still needs a permit.
- Can I act as my own contractor on my home in North Carolina?
- Often yes. Under the owner exemption to North Carolina's general-contractor licensing law (G.S. 87-1 and 87-14), a homeowner can act as their own general contractor on a residence they own and intend to occupy. Selling or renting it within 12 months can forfeit the exemption. You still must pull any required permits and pass inspections.
- Where does the $40,000 exemption come from?
- It is set by North Carolina General Statute 160D-1110(c), which raised the threshold to $40,000 effective October 1, 2023.
