About Bunn and Its Homes
Bunn took shape after about 1909 beside a rail line the Montgomery Lumber Company ran up from Spring Hope, and it was chartered in 1913. Its houses have hardly been written about, so what an attic needs here comes from looking at that one house.
Bunn, in Franklin County, grew from 334 people in 2020 to 391 in 2025 (Census Bureau estimates), on 0.54 square miles.

Bunn Insulation FAQs
Is my Bunn house on any historic list?
None that the state keeps. The National Register has nothing inside the town limits, and the one listing nearby, the Baker Farm, is recorded as outside them. Franklin County appears on the 2023 commission roster with just one entry, the Louisburg commission. The county's 2015 survey rechecked old sites here, but a survey adds no rules. So nothing historic stands in the way of attic work.
We are fixing up an older house in Bunn. When should the attic be done?
After the wiring and the roof, and after any new ceiling lights go in. The town itself notes that its old homes are being renovated. If the house still has knob-and-tube wiring, ENERGY STAR says it must be dealt with before insulation touches it, and damp insulation means the roof needs fixing first. New wiring and light fixtures leave holes in the ceiling, so we seal those from above. Recessed lights need an IC rating, or a 3-inch clearance from insulation.
Does attic insulation in Bunn need a permit?
Bunn Town Hall can say whether Franklin County Building Inspections, the town itself or another office handles permits in Bunn; ask before work starts.
