Taylorsville, in Alexander County, grew from 2,298 people in 2020 to 2,333 in 2025 (Census Bureau estimates), on 2.4 square miles.
Taylorsville has about 1,040 housing units, 6 percent of Alexander County's; about 54 percent of the town's households own their home.

Taylorsville Homes and Their Attics
Dormered Bungalows and Revival Cottages
A 2023 survey by the State Historic Preservation Office found that the bungalow flourished in Taylorsville in the 1910s and 1920s, and that many frame examples remain, some with shingled dormers. From the late 1930s on, the Period Revival cottage took hold: one story, often brick, with a steep front-gabled entrance. Where a bungalow's dormer lights a room, that room is tucked into the roof, with short walls on each side and wedges of unheated attic behind them. ENERGY STAR counts the areas behind and below knee walls among the usual leak points. We seal and insulate those wedges as well as the attic over the ceiling.
Ranch Houses of the Furniture Years
The same survey dates the town's early ranch houses to about 1951 and 1952 and says the form went on to become prolific here. Most houses of the postwar years were one or one and a half stories. Furniture plants opened in the late 1950s, and new streets such as Northwood Park followed in the 1960s and 1970s. As the housing figures on this page show, about half of the homes here predate 1970. A ranch roof is low-pitched, so there is little height where it meets the outside walls, and that is where attic insulation tends to run thin. Baffles over the soffit vents keep air moving above the new layer.
Attic Insulation in Taylorsville
About 40 percent of Taylorsville's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1940 to 1969, about 40 percent of Taylorsville homes often have little insulation.
The Local Climate
Taylorsville's center sits about 1,240 feet above sea level, under a mile from NOAA's Taylorsville station, the best match for Taylorsville. The station's 1991 to 2020 normals average about 3,690 heating and 1,260 cooling degree days a year, so at Taylorsville's station, heating needs outweigh cooling.
Homes by Age: What It Means for the Attic
About 58 percent of Taylorsville housing units are detached single-family houses, about 10 percent mobile homes.
Built from 1970 to 1989, about 30 percent of Taylorsville homes may hold settled fiberglass; check its depth against the joists.
About 55 percent of Taylorsville's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 28 percent of Taylorsville units sit in buildings of two or more homes, where the attic is often shared.

Taylorsville Insulation FAQs
Is my Taylorsville home covered by the downtown historic district?
Very likely not. The district, added to the National Register in 2024, is drawn around the stores, offices, churches and public buildings near the courthouse. And a National Register listing, the state preservation office explains, leaves an owner free to repair or alter the house when the money is their own. Alexander County had no local preservation commission on the state's roster as of 2023. Sealing and insulating an attic is indoor work in any case.
Is my house near the old Taylorsville Cotton Mill a former mill house?
It could be. The cotton mill opened in 1907, and the 2023 survey says the mill company laid out and sold lots on Highland Avenue, Prohibition Avenue and Baptist Street, northwest of the mill. Two small one-story houses in that area, with side gables, front porches and rear ells, were standing before 1924 and may date from that time. The small mill village east of the mill on the 1924 map is gone. A rear ell often has its own low attic, so we check it separately.
Could a house from Taylorsville's early electric years have knob-and-tube wiring?
Yes. The 2023 survey notes that the town first got electricity in 1917, when the owners of the Alspaugh Cotton Mill built a hydroelectric plant. That puts the first wired houses squarely in the knob-and-tube era, which ENERGY STAR places before 1930. Insulation packed around that kind of wiring is a fire risk. In a house from the 1910s or 1920s, an electrician looks at the wiring before we add anything, and any live run is left uncovered.
Could the old insulation in a Taylorsville attic be vermiculite?
It could: about 30 percent of Taylorsville's homes predate 1960. If a Taylorsville attic holds a pebble-like gray-brown or silver-gold fill, leave it undisturbed: the EPA says vermiculite may contain asbestos.
Does attic insulation in Taylorsville need a permit?
Taylorsville Town Hall can say whether Alexander County Building Inspections, the town itself or another office handles permits in Taylorsville; ask before work starts.
