About Newport and Its Homes
Newport, first called Bells Corners, grew up on the Newport River and was incorporated in 1866, its center having shifted north to meet the railroad that came through in 1857. For all that history, the bulk of its homes date from 1970 on.
Newport, in Carteret County, grew from 4,344 people in 2020 to 4,500 in 2025 (Census Bureau estimates), on 7.69 square miles. That makes Newport the third-largest town in Carteret County.
Newport has about 1,850 housing units, 4 percent of Carteret County's; about 61 percent of the town's households own their home.

Newport Homes and Their Attics
Story-and-a-Half Houses With Bedrooms Upstairs
The county's 2012 architectural survey found that in Newport Township the old way of building barely changed after the Civil War. The common house stayed one and a half stories, with a shed-roofed porch across the front and bedrooms in the attic that grew taller over the years. The survey even calls one house in town, built in 1907, unusual because it has no attic story at all. In a house with rooms under the roof, the cold edge is more than one ceiling. The low side spaces behind the knee walls leak air, and so do open floor cavities beneath them, so both are sealed and insulated along with the attic overhead.
Attic Insulation in Newport
About 15 percent of Newport's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1970 to 1989, about 35 percent of Newport homes may hold settled fiberglass; check its depth against the joists.
The Local Climate
Newport's center sits about 20 feet above sea level, 1 mile from NOAA's Newport/Morehead City Weather Office station, the best match for Newport. The station's 1991 to 2020 normals average about 2,780 heating and 1,710 cooling degree days a year, so at Newport's station, heating needs outweigh cooling.
Readings change over short distances around Newport: NOAA's Morehead City 2 WNW station, 8 miles away, averages about 2,480 heating degree days. The state energy code marks Carteret County warm and humid.
Homes by Age: What It Means for the Attic
Some 66 percent of Newport housing units are detached single-family houses.
From 1990 to 2009, about 30 percent of Newport homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
About 20 percent of Newport's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 28 percent of Newport units sit in buildings of two or more homes, where the attic is often shared.

Newport Insulation FAQs
After Florence's rain, how would I know if my Newport attic got wet?
Look above any ceiling stain from that storm. The National Weather Service office in Newport measured 25.20 inches of rain from Hurricane Florence in 2018, and its review put the town among the hardest-hit places. Insulation that is damp or stained marks a roof leak, and ENERGY STAR says that leak gets fixed before any insulation work. Then we vacuum out what was spoiled and blow in fresh insulation.
Is any building in Newport protected as historic?
Not by any listing the state keeps. Newport has no property on the National Register roll, and in the state's 2023 directory of preservation boards Carteret County's lone entry is Beaufort's. The 2012 county survey did record older buildings in town, among them a two-story Greek Revival house near the old depot site and a Primitive Baptist church of about 1885. So attic insulation and sealing here face no historic review.
Does attic insulation in Newport need a permit?
Newport Town Hall can say whether Carteret County Planning & Development, the town itself or another office handles permits in Newport; ask before work starts.
