About Locust and Its Homes

Locust, on the western side of Stanly County, began in the late 1860s as a crossroads stop on the old Charlotte Road, with a post office called Locust Level from 1869. The name lost its second word in 1894, and the town still sits where routes to Charlotte, Albemarle, Concord and Monroe meet.

Locust, in Stanly County, grew from 4,858 people in 2020 to 6,120 in 2025 (Census Bureau estimates), on 8.22 square miles. That makes Locust the second-largest town in Stanly County.

Locust has about 2,300 housing units; 87 percent of the city's households own their home.

Locust Homes and Their Attics

A Crossroads Town of Mostly Newer Houses

Locust was incorporated in 1905, the Gazetteer records, but for a long stretch it hardly functioned as a town government. Its post office closed in 1919 and did not reopen until 1955. Housing came later still: going by the census estimate on this page, most homes in town were built after 1969. A bedroom or game room set above an attached garage deserves a close look at the floor that divides them. Building America advises air sealing that floor and keeping its insulation pressed tight to the subfloor, so garage air stays out of the room above. We insulate garages too.

Attic Insulation in Locust

About 15 percent of Locust's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.

In 2010 or later, about 45 percent of Locust homes went up; check their air sealing as well as the depth.

The Local Climate

Locust's center sits about 720 feet above sea level, 14 miles from NOAA's Concord station, the best match for Locust. The station's 1991 to 2020 normals average about 3,290 heating and 1,760 cooling degree days a year, so at Locust's station, heating needs outweigh cooling.

Homes by Age: What It Means for the Attic

Some 85 percent of Locust housing units are detached single-family houses.

From 1990 to 2009, about 20 percent of Locust 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 Locust's housing units predate 1980; nearly all predate the state's 1978 insulation rule too.

Locust Insulation FAQs

Are any houses in Locust on a historic register?

None, according to the state. The State Historic Preservation Office's National Register roster shows no property in Locust or its vicinity. On the office's 2023 list of local preservation commissions, Stanly County's only entry is Albemarle's, which does not reach this town. No historic body, then, weighs in on attic jobs within Locust.

Why does the upstairs room under the roof in my Locust house run hot?

One common cause is the side attic behind its walls. Where a second-floor room is tucked under the roof slope, short knee walls separate it from wedge-shaped attic spaces at the sides. ENERGY STAR names the hollows behind and beneath knee walls as typical leak points. An Iowa state training text for home repair crews says that triangle of attic is frequently leaky. So the side spaces get sealed and insulated along with the main attic overhead.

Does attic insulation in Locust need a permit?

Locust City Hall can say whether Stanly County Central Permitting, the city itself or another office handles permits in Locust; ask before work starts.
