Work can't begin at the jobsite until permits are issued, so Kevin takes Janet to meet the Concord building commissioner, John Minty, to see what potential roadblocks she's facing in trying to turn an accessory building into a full-time residence. Then Kevin meets local architect Holly Cratsley to see a new home she designed to look like an old home, and an accompanying timber frame barn. Meanwhile, with flashlights, ladders, and archival photographs, Norm and preservation architect Leonard Baum reconstruct the architectural history of the project house, learning that the building started out as a one-story chicken coop with a hip roof, and that it is needed older than the zoning law itself - a finding that's essentual to moving forward with the town.
