About Lake Santeetlah and Its Homes

Lake Santeetlah Insulation FAQs
Was my 1960s cabin at Lake Santeetlah built with attic insulation?
Nobody required it. The town's own history says the early cottages of the 1960s were simple, and that homes built from the 1990s on were much larger. A cabin from the resort's first years predates the 1978 state rule that tied new houses to insulation standards, so nothing required its builder to insulate it. The later, larger houses were begun after that rule took effect. With either, the depth gets a tape measure on the morning of the job, before anything is blown in.
Is anything in Lake Santeetlah on the National Register?
Not in the town itself. The dam, powerhouse and works that made the lake are listed together as the Santeetlah Hydroelectric Development, but the state places them near Robbinsville rather than in Lake Santeetlah. The state's 2023 roster shows no preservation commission in Graham County. Your attic is therefore your own call. What decides the work is how your house was built and what is up there now.
Does attic insulation in Lake Santeetlah need a permit?
Lake Santeetlah Town Hall can say whether Graham County Building Inspections, the town itself or another office handles permits in Lake Santeetlah; ask before work starts.
