Lansing Homes and Their Attics
Story and a Half Bungalows on the Valley Slopes
The 2011 nomination for the Lansing Historic District counts bungalows of the 1920s and 1930s as the majority of its houses. Its inventory lists about ten houses of one and a half stories, most of them with dormers. Upstairs, those rooms are tucked partly into the roof, with short knee walls along the sides. ENERGY STAR's list of attic leak spots includes the open framing behind and beneath knee walls. An Iowa state training text adds that the wedge of attic behind a knee wall is often leaky. Those side attics get sealed and insulated along with the attic over the ceiling.

Lansing Insulation FAQs
Will the Lansing Historic District listing restrict insulating my house?
No. Lansing's district, listed in 2011, takes in houses as well as stores and covers many of the buildings inside the town limits. A National Register listing by itself does not restrict a private owner who maintains or changes a property with private money, according to the State Historic Preservation Office. The office's 2023 roster lists no preservation commission for Ashe County, so insulating and air sealing need no district approval.
My Lansing bungalow has an interior brick chimney. What happens around it in the attic?
It gets sealed and fenced off, never buried. The district inventory describes interior brick chimneys in a number of the town's older houses. Where the brick passes through the attic floor, the opening is covered with sheet aluminum and sealed with caulk rated for high heat. A metal collar then holds loose insulation back from the brick by the 2 inches that codes usually ask for, according to ENERGY STAR.
Does attic insulation in Lansing need a permit?
Lansing Town Hall can say whether Ashe County Building Inspections, the town itself or another office handles permits in Lansing; ask before work starts.
