Catawba Homes and Their Attics
Kitchen Ells Behind the 1870s Houses
The 1986 nomination for the Catawba Historic District dates the town's oldest houses to the early 1870s. They were generally two stories tall and a single room deep, with chimneys on the gable ends and a kitchen wing of one or two stories at the back. Where a rear wing like that has a roof of its own, the space above its ceiling is a separate attic. It may hold a different depth of insulation from the main house, or nothing. Each space gets measured, and both are brought up to an even depth with no thin patches.

Catawba Insulation FAQs
Do I need approval to insulate an attic in the Catawba Historic District?
Not for the insulation. Catawba's district went on the National Register in 1986. According to the State Historic Preservation Office, being listed places no limits on an owner who spends private money on a private house. Hickory's commission is the only one in Catawba County on the state's 2023 roster, so no local district review applies in town as far as those records show. Insulating and sealing an attic happen indoors in any case.
Could an older Catawba house still have its first wiring in the attic?
It could, so the wiring is looked at before anything else. The district's houses range from the early 1870s through the 1920s, so any of them may first have been wired before 1930. Knob-and-tube, the wiring of that era, is a fire hazard in ENERGY STAR's view wherever insulation touches it. An electrician sorts out any old wiring first. Any run of live knob-and-tube stays exposed, with no insulation laid over it.
Does attic insulation in Catawba need a permit?
Catawba Town Hall can say whether Catawba County Building Services, the town itself or another office handles permits in Catawba; ask before work starts.
