How long does a building permit take in North Carolina? Days by office and type of work, 2026

How long a building permit takes in North Carolina depends less on the state than on the office. Each city and county runs its own review, and their records show the spread: over the last 12 months a new house was typically permitted five days after the application in Gaston County, 20 days in unincorporated Wake County and 46 days in Raleigh. Smaller jobs move faster, and most electrical, plumbing and HVAC permits are issued within a day or two. Here is what nine offices' own records show, job by job, and what state law says an office has to do.

New homes: days from application to permit, by office

The median is the typical wait: half of permits took less, half took more. The other columns show the slow end, which matters more for scheduling a crew, and how many permits came through within three weeks, close to the 15 business days state law gives an office for its first review.

The fast offices issue four out of five new-home permits inside three weeks. In Raleigh, Cary, Asheville and Guilford County's office it's one in five or fewer. Asheville's slow end is long partly because some of its records are opened well before the plans are complete, so its median is the better guide there.

Remodels, additions, decks, pools and roofs

Smaller jobs move faster almost everywhere, but not by the same amount. An addition often waits as long as a new house or longer, because it gets a structural plan review; a reroof or a remodel with no structural change is often quicker.

Trade permits: usually a day or two

A standalone electrical, plumbing or HVAC permit needs no plan review in most offices, and it shows. The median electrical permit was issued in one day in Gaston, Guilford, Onslow and New Hanover counties and in Cary, three days in Wake County's office and four in Morrisville; HVAC permits took one or two days in most of the same offices. In Gaston and Guilford counties more than 40% of electrical, plumbing and HVAC permits were issued the day they were applied for. Raleigh and Asheville are the exceptions, at around four weeks for the electrical permits in their records.

What North Carolina law requires of permit offices

For one- and two-family homes, a local government that reviews residential plans must complete its initial review within 15 business days of getting the plans, at the same time as any other state, federal and local approvals the project needs. If the review isn't done within 20 business days, the office refunds 10% of the permit application fee for each business day of delay, up to 10 business days (G.S. 160D-1110(b)).

For commercial and multifamily projects with plans sealed by an engineer or architect, G.S. 160D-1110.1 sets out a faster path. The office must offer a pre-submittal meeting within five business days of a request, decide on a complete application within 45 days unless the applicant agrees otherwise (with up to 10 more days after it receives requested changes), and, if it doesn't, the applicant may hire a certified engineer or architect for a third-party review. The office then has three business days to issue the permit and must refund or waive the plan review and permit fees. Applicants who held a pre-submittal meeting can also ask for at-risk permits to start the foundation, and then the structure, before every approval is in.

Those deadlines time the office's review, not the whole wait. The application-to-issue days in the tables above include the time plans spend with the applicant for corrections, and the time a permit waits on zoning or other sign-offs, so an office can meet the statutory deadline and still show a median of six weeks.

Is it getting faster?

In the slower offices, yes. Compared with the 12 months before, the median new-home wait fell from 107 to 67 days in Asheville, from 105 to 77 in Guilford County's office and from 55 to 46 in Raleigh. It rose in two of the faster ones: from 16 to 20 days in Wake County's office and from 9 to 14 in Onslow County, where it has crept up quarter by quarter since 2024. Gaston County has held at five or six days throughout.

Why one permit takes longer than another

• Plan corrections. When a reviewer sends comments, the clock usually keeps running until revised plans come back, so a slow response adds directly to the wait.
• Other approvals. A permit can wait on zoning, a driveway or utility connection, a septic permit from the county health department, or an approved erosion and sedimentation control plan, which state law requires before a permit for land-disturbing work (G.S. 160D-1110(e)).
• Incomplete applications. Missing plot plans, energy forms, truss drawings or the lien agent designation for jobs of $40,000 or more send an application back before review starts.
• The kind of work. New buildings and additions get a structural plan review; trade permits and like-for-like replacements usually don't.
• The office and the season. Workload varies, and the same builder can wait a week in one county and six in the next.

How to get a building permit faster

• Check first whether you need one. Work costing $40,000 or less on a house, farm building or commercial building needs no building permit unless it involves load-bearing structure, added plumbing, electrical or HVAC work, or added roofing, among other exceptions (G.S. 160D-1110(c)).
• Send a complete application, with every form the office lists, and answer review comments the same day if you can.
• On a commercial or multifamily job with sealed plans, ask for the pre-submittal meeting the law guarantees, and consider at-risk foundation and structure permits.
• If a commercial review runs past the 45-day deadline, the third-party review route under G.S. 160D-1110.1 is open to you.
• Plan around the office's median, and allow for its slowest 10% when you promise a start date.

Once you have it: how long a permit lasts

A North Carolina building permit expires six months after it's issued if the work hasn't started, or sooner if a local ordinance sets a shorter time, and it expires if work stops for 12 months (G.S. 160D-1111). After that, a new permit is needed before work continues. At the other end, a new house still needs its final inspections and a certificate of occupancy before anyone moves in.

How the numbers were counted

Permits issued in the 12 months to October 23, 2026, counting the days from the application date each office records to the date it issued the permit; the comparison year is the 12 months before. Gaps of more than two years are left out as data errors, and a type of work needs at least 20 permits in an office to get a figure. The same figures, updated nightly, are in TarSignal's permit wait-time tool.

Offices are left out when their records can't support the measure: Mecklenburg, Durham, Brunswick, Johnston, Union, Alamance, Cabarrus and Garner record no application date, and Apex, Fuquay-Varina and Wake Forest show most permits, even new homes, as issued the day they were applied for. An earlier version of this article listed the City of Greensboro; its permits are entered after plan review, under a separate plan review record, so they show as issued almost the day they were entered, and it's no longer included.
