COEUR D'ALENE, Idaho (AP) — Northern Idaho authorities say a 600-square-foot treehouse featured on a cable program about treehouses lacks a building permit.

The Coeur d'Alene Press reports in a story on Tuesday that treehouse owner Paul Buttars failed to respond within 45 days to a violation notice sent by Kootenai County officials. The DIY Network's "The Treehouse Guys" in June featured the treehouse that's 30 feet off the ground and supported by three Douglas firs.

County officials sent the violation notice the day after the program ran. Buttars says he plans to use the treehouse for lunch breaks and dinners for his zip-line tour company. Buttars has a conditional use permit for the zip-line, but county officials could revoke the permit if the treehouse isn't brought into compliance.
