About Dobson and Its Homes
Dobson was made the Surry County seat in the early 1850s and incorporated in 1891, and its 1916 courthouse is the only National Register building in town. Published surveys say almost nothing about Dobson's houses, so advice for an attic here starts from the age and build of that particular house.
Dobson, in Surry County, grew from 1,464 people in 2020 to 1,474 in 2025 (Census Bureau estimates), on 2.03 square miles. That makes Dobson the third-largest town in Surry County.
Dobson has about 660 housing units, 2 percent of Surry County's; about 49 percent of the town's households own their home.

Attic Insulation in Dobson
About 30 percent of Dobson's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
From 1990 to 2009, about 35 percent of Dobson homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Dobson's center sits about 1,260 feet above sea level, 8 miles from NOAA's Mount Airy 2 W station, the best match for Dobson. The station's 1991 to 2020 normals average about 4,410 heating and 970 cooling degree days a year, so at Dobson's station, heating needs outweigh cooling.
Dobson sits about 200 feet above the station, so expect slightly colder winters.
Homes by Age: What It Means for the Attic
About 58 percent of Dobson housing units are detached single-family houses.
Built from 1970 to 1989, about 30 percent of Dobson homes may hold settled fiberglass; check its depth against the joists.
About 50 percent of Dobson's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 39 percent of Dobson units sit in buildings of two or more homes, where the attic is often shared. Renters hold about 51 percent of Dobson's occupied homes, so many attic decisions rest with landlords.

Dobson Insulation FAQs
Is my house in Dobson listed on a historic register?
Not that the state records show. The one National Register listing inside the town limits is the Surry County Courthouse, built in 1916. A listed two-story frame house with 1799 painted on its chimney stands outside town, in the Fisher River bottom. Surry County has a single preservation commission on the state's 2023 list, and it serves Mount Airy. Historic status puts no hurdle in front of insulating a private home here.
What needs checking before insulation goes into one of the older houses in Dobson?
The wiring and the roof, first. ENERGY STAR cautions that knob-and-tube wiring, used in houses wired before about 1930, can become a fire hazard where insulation lies against it. An electrician has to inspect and correct it before any insulation goes near it. Insulation that is damp or matted, or stained by water, points to a leaking roof, and a roofer repairs that before we start. A town that was incorporated in 1891 can have houses old enough for either problem.
Could the old insulation in a Dobson attic be vermiculite?
It could: about 20 percent of Dobson's homes predate 1960. If a Dobson 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 Dobson need a permit?
Dobson Town Hall can say whether Surry County Inspections, the town itself or another office handles permits in Dobson; ask before work starts.
