How long might review take?
N/A; the county application says the applicant will be contacted when the permit is ready but publishes no standard review timeline.

The department contacts the applicant when the permit is ready; call 815-895-7188 for inspection coordination.
Which codes and exemptions should I review?
The Community Development Department interprets and enforces DeKalb County's Unified Comprehensive Plan, Zoning Ordinance, Subdivision Regulations, building codes, and Stormwater Management Regulations. The reviewed county materials do not state a current 2026 International Building Code edition. The county's zoning instructions identify fences and walls, off-street parking/loading areas, home occupations and miscellaneous zoning uses, agricultural structures, and residential accessory structures under 120 square feet without utilities as requiring a Zoning Permit; no broad minor/cosmetic exemption list was identified.
