Which codes and exemptions should I review?
The American Legal Publishing page linked from the official county site identifies the 2023 Grundy County Code as current, including Title 6 Building Regulations and Title 8 Unified Development Code. The cited permit chapter applies to buildings and structures outside municipal limits; no separate 2026 edition was identified. A permit is required in advance for buildings, structures, plumbing, and electrical work outside municipal limits when erected, installed, altered, converted, remodeled, structurally repaired, moved, or changed. Plans may be waived for minor alterations without structural changes and residential accessory buildings not over 700 square feet when adequately described, but the code does not state that the work is permit-exempt.
