Hot Springs Homes and Their Attics
Railroad Boom Houses Along Bridge Street
Once the trains came, Hot Springs roughly doubled in size between 1902 and 1910, and by 1915 two lumber companies had opened to meet the demand for building materials. The 2009 historic district nomination describes two houses of that era on Bridge Street. One, from about 1890, is a story-and-a-half Queen Anne house shaped like a cross, with a paneled brick chimney at its center. The other is a bungalow of about 1920 with shed dormers front and back. Under a cross-shaped roof the attic can split into several arms that meet around the chimney. We check each arm. The opening around the chimney gets a metal cover sealed with high-heat caulk, and the insulation is held back from the brick.
Attic Insulation in Hot Springs
About 35 percent of Hot Springs' homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
The Local Climate
Hot Springs' center sits about 1,330 feet above sea level, under a mile from NOAA's Hot Springs station, the best match for Hot Springs. The station's 1991 to 2020 normals average about 3,800 heating and 1,270 cooling degree days a year, so at Hot Springs' station, heating needs outweigh cooling.
Readings change over short distances around Hot Springs: NOAA's Greeneville Experiment Station, TN, 15 miles away, averages about 4,170 heating degree days.
Homes by Age: What It Means for the Attic
With about 310 housing units in Hot Springs, read the figures as rough proportions.
Built from 1940 to 1969, about 30 percent of Hot Springs homes often have little insulation. From 1990 to 2009, about 20 percent of Hot Springs homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
About 60 percent of Hot Springs' housing units predate 1980; nearly all predate the state's 1978 insulation rule too.

Hot Springs Insulation FAQs
Does the Hot Springs Historic District cover the homes in town?
Only two of them. The district is the old business core along Bridge Street and South Andrews Avenue, mostly brick and stone storefronts, with just two houses and a church inside its lines. Being in a Register district is a matter of record, not a set of rules for owners paying their own way, as the state office explains. Madison County has no commission on the state's 2023 roster either.
What gets checked before insulating a Hot Springs house from the boom years?
Wiring, roof and vents. A house from the decades after 1882 may have been wired with porcelain knobs and tubes. Buried in insulation, that old system can turn into a fire hazard, ENERGY STAR cautions, so an electrician sees it first. Damp insulation is the roof's problem to solve before ours. And fans from the bath or kitchen must blow outside, not into the attic.
Could the old insulation in a Hot Springs attic be vermiculite?
It could: about 20 percent of Hot Springs' homes predate 1960. If a Hot Springs 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 Hot Springs need a permit?
Hot Springs Town Hall can say whether Madison County Inspections and Zoning, the town itself or another office handles permits in Hot Springs; ask before work starts.
