About Landis and Its Homes
Landis was incorporated on March 7, 1901, by farm families along the railroad, and a cotton mill with its own depot and cotton siding soon employed many of its people. Little has been published about its older houses, and most of its homes came much later.
Landis, in Rowan County, grew from 3,712 people in 2020 to 3,885 in 2025 (Census Bureau estimates), on 3.4 square miles. That makes Landis the third-largest town in Rowan County.
Landis has about 1,770 housing units, 3 percent of Rowan County's; about 86 percent of the town's households own their home.

Attic Insulation in Landis
If the joists show above the insulation in a Landis attic, ENERGY STAR says to add more insulation.
The Local Climate
Landis' center sits about 870 feet above sea level, 9 miles from NOAA's Concord station, the best match for Landis. The station's 1991 to 2020 normals average about 3,290 heating and 1,760 cooling degree days a year, so at Landis' station, heating needs outweigh cooling.
Landis sits about 150 feet above the station, so expect slightly colder winters. Readings change over short distances around Landis: NOAA's Salisbury 9 WNW station, 11 miles away, averages about 3,760 heating degree days.
Homes by Age: What It Means for the Attic
About 93 percent of Landis housing units are detached single-family houses. With about 1,770 housing units in Landis, read the figures as rough proportions.
Built from 1970 to 1989, about 10 percent of Landis homes may hold settled fiberglass; check its depth against the joists. In 2010 or later, about 25 percent of Landis homes went up; check their air sealing as well as the depth.

Landis Insulation FAQs
Could a historic listing restrict changes to my Landis house?
No. Search the state's National Register rows for Rowan County and Landis does not come up, nor does any listing just outside it. The town also lacks a preservation commission of its own on the 2023 state roster. The old post office, jail and railroad depot that Landis plans to show in its new park are town projects. So insulating or air sealing your private house here involves no historic review.
Why is the bonus room over our Landis garage never comfortable?
Two likely culprits are air slipping through the floor under it and through the low side walls beside it. This page's housing numbers show the town is mostly newer than 1970. Where a bedroom or bonus room sits on top of a garage, Building America guidance makes the floor between them airtight. The insulation there is held snug to the subfloor. The spaces behind that room's knee walls are on ENERGY STAR's list of leak spots too. We seal and fill both, and we insulate garages as well.
Does attic insulation in Landis need a permit?
Landis Town Hall can say whether Rowan County Building Inspections, the town itself or another office handles permits in Landis; ask before work starts.
