About seven months from building permit to final inspection, with the permit itself taking roughly three weeks before that. We pulled New Hanover County’s own permit records on October 31, 2026: of the 1,015 new single family homes the county finaled this year, the median took 218 days from permit issue to final, which is 7.2 months.
Buyers ask this question for one of two reasons. Either they are deciding between a spec home that is nearly done and a house they would start from scratch, or they have a lease ending and need to know whether the math works. Both deserve a real number rather than a builder’s best case.
So here is the local record rather than a national average. New Hanover County publishes its building permits with application, issue and final inspection dates, and that lets us measure how long houses here actually take.
What the local permit record shows
Querying the county’s building permit service on October 31, 2026, we found 1,065 permits coded as a new single family residence with a final inspection date in 2026, 1,015 of them with usable issue and final dates. The median was 218 days from permit issue to final, about 7.2 months. The mean was 252 days, which tells you the slow ones are slower than the fast ones are fast.
The spread matters more than the middle. A quarter of those homes finaled within 142 days, under five months. A quarter took more than 328 days. And 21 percent, better than one in five, took longer than a year. If you are planning a move around a build, you are planning around that tail and not around the median.
Two more numbers from the same data. Getting the permit itself took a median of 20 days from application to issue in 2026, which is quick by the standards of most growing counties. And the picture is improving: homes the county finaled in 2025 took a median of 242 days, about 8.0 months, so this year’s 218 days is roughly three and a half weeks faster.

How does that compare to the rest of the country?
Favorably. The National Association of Home Builders’ analysis of the Census Bureau’s Survey of Construction, published September 8, 2026, put the 2025 national average at 1.4 months from authorization to start and 7.4 months from start to completion, for 8.8 months in total. The South Atlantic division, which includes North Carolina, was the fastest in the country at 7.6 months from authorization all the way to completion, against 13.5 months in New England.
Our county median of 7.2 months from permit to final sits right in that range, which is a useful sanity check on both numbers. It also means that if a builder tells you nine or ten months, they are not padding. They may be telling you about a custom house, a difficult lot, or a trade schedule they do not control.
What the timeline costs you at today’s rates
This is where a seven month build turns from a scheduling question into a money question. The 30-year fixed averaged 7.24 percent for the week ending October 29, 2026, down from 7.32 percent the week before, and a rate lock on a house that is not framed yet is a different product from a lock on a resale closing in 30 days. Ask for extended lock pricing in writing before you sign, and ask what happens if the build runs past it. We wrote about the mechanics in our post on what happens to your rate lock when closing gets delayed.
The builder incentive is tied to the same clock. As of October 17, 2026, Mungo Homes was offering a 2-1 buydown at 3.49 percent in year one, 4.49 in year two and 5.49 for years three through thirty on eligible homes through its lender, or up to $20,000 in savings instead, and Logan Homes was offering a rate as low as 5.75 percent or up to $5,000 toward buyer fees on its first time buyer package, or $20,000 use-as-you-choose on select homes. Those terms change monthly, and an incentive you qualified for in November is not guaranteed to exist when a June delivery finally closes. Our new construction pages track the current terms, and our mortgage update has the weekly rate.
If the schedule is what you are worried about, the honest alternative is a spec home that is already under roof. You give up choices and you often pay a little more for the finishes someone else picked, and you get a delivery date you can plan a lease around. We laid out that trade in spec home or build to order.
Three caveats on our own numbers, because they matter. First, these are permits issued by New Hanover County, which handles the unincorporated county and the areas it serves rather than every address inside the City of Wilmington, and Brunswick and Pender counties run their own systems with their own queues. Second, the clock we measured starts at permit issue, and your clock starts when you sign. On a build-to-order you can spend weeks on plan selection, lot release and design center decisions before anyone applies for a permit, and on a lot that still needs roads, water and sewer you can spend months. Third, a final inspection is not a closing: your closing follows the certificate of occupancy, and the two can be days or weeks apart. Add to all of that the fact that one in five of these homes took more than a year, and the right way to use the 7.2 month median is as a planning number, not a promise. Do not give notice on a lease against it.
Related questions people also ask
How long does it take to build a house in New Hanover County?
The median was 218 days, about 7.2 months, from building permit issue to final inspection among the 1,015 new single family homes New Hanover County finaled between January 2 and October 29, 2026. A quarter were done inside 142 days and a quarter took more than 328 days, so the range around that median is wide. Getting the permit added a median of 20 days before the clock even started, and time spent choosing a plan or developing a lot comes before that.
Is buying a spec home faster than building to order?
Almost always, because the permit, the site work and usually the framing are already behind it. A spec home that is under roof can close in the same timeframe as a resale, in our experience usually 30 to 60 days, which is why buyers with a lease ending tend to end up in one. The trade is choice: you take the floor plan, the lot and the finishes the builder already selected, and you lose the ability to change them. Price the incentive on each option, because builders often push harder on standing inventory.
What delays new construction around Wilmington the most?
In our experience the common causes are trade scheduling, inspection sequencing and weather, in that order, with hurricane season able to stop exterior work for days at a time in late summer. Lot readiness is the other big one: a home on a lot that still needs roads, water and sewer waits on infrastructure rather than on the builder’s crews. None of that shows up in a permit database, which is one reason we tell buyers to ask a builder for their last three actual delivery dates rather than their average.
Before you sign a build contract, get three things in writing: the builder’s estimated substantial completion date, what happens to your rate lock and incentive if that date moves, and the last three homes they actually delivered in that community with their start and closing dates. Those three answers will tell you more than any average will. We are glad to sit down with a specific builder’s contract and go through it with you line by line.
