About Saluda and Its Homes
Saluda, chartered in 1881 at the top of the Saluda Grade, became a summer resort for families from Charleston, Columbia and New Orleans soon after the first train arrived in 1878. Saludians built mostly east of the tracks, while summer visitors put up seasonal houses to the west.
Saluda, in Polk County, grew from 631 people in 2020 to 671 in 2025 (Census Bureau estimates), on 1.56 square miles.
Saluda has about 540 housing units; about 84 percent of the city's households own their home.

Saluda Homes and Their Attics
Boarding Houses That Became Saluda Homes
Many of Saluda's larger summer homes and boarding houses were built in the Queen Anne style, a 2005 nomination notes. A local builder made a trade of roomy houses for wealthy visitors. During the Depression some hotels, inns and boarding houses burned, came down or were turned into private homes, and after the war the town settled into a quieter residential life. A big house converted that way may have attic rooms finished long after it was built, as one listed inn did in the 1970s. Rooms like that sit against sloped ceilings and short side walls, where air slips into the cold corners behind them. Those corners get sealed and insulated along with any open attic above.
Attic Insulation in Saluda
If the joists show above the insulation in a Saluda attic, ENERGY STAR says to add more insulation.
The Local Climate
Saluda's center sits about 2,090 feet above sea level, 9 miles from NOAA's Hendersonville 1 NE station, the best match for Saluda. The station's 1991 to 2020 normals average about 4,170 heating and 900 cooling degree days a year, so at Saluda's station, heating needs outweigh cooling.
Readings change over short distances around Saluda: NOAA's Asheville Regional Airport station, 17 miles away, averages about 3,840 heating degree days.
Homes by Age: What It Means for the Attic
Some 91 percent of Saluda housing units are detached single-family houses.
Built from 1970 to 1989, about 15 percent of Saluda homes may hold settled fiberglass; check its depth against the joists. From 1990 to 2009, about 25 percent of Saluda homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
About 65 percent of Saluda's housing units predate 1980; nearly all predate the state's 1978 insulation rule too.

Saluda Insulation FAQs
Was my old Saluda summer house built to be lived in all winter?
Not necessarily. Saluda was a summer resort. Some people lived here all year, but the town filled up each summer. Visitors built seasonal houses west of the railroad. A house meant for July may never have had insulation put in for January, or it may have been brought up to date by a later owner. Before starting, the crew goes over the depth across every part of the ceiling, the wiring, and any sign of a roof leak with you.
Does the Saluda Main Street Historic District include my house?
Very likely not. The district listed in 1996 runs along Main Street between Cullipher and Carolina streets. Its nomination describes mostly commercial buildings, with two church buildings, a government building, a small park and the tracks. The residential hills around it lie outside. National Register status puts no limits on a private owner paying for work, the state preservation office explains, and the city lists a Planning Board but no preservation commission among its boards.
Could the old insulation in a Saluda attic be vermiculite?
It could: about 50 percent of Saluda's homes predate 1960. If a Saluda 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 Saluda need a permit?
Saluda City Hall can say whether Polk County Building & Fire Inspections, the city itself or another office handles permits in Saluda; ask before work starts.
