Kendall County, IL Building Safety: Building Inspections (2026)

Kendall County Code § 8-33 sets the ground rules for every inspection required under the Building Code: the owner or contractor must request the designated inspection at least 48 hours in advance, keep an approved set of building plans on the job site, and have a representative of the property owner present, or the inspection fails. Sections 8-34 through 8-45 then lay out twelve sequential stages: a site inspection at permit application to confirm zoning, floodplain and stormwater compliance (§ 8-34); footing (§ 8-35) and foundation wall (§ 8-36) inspections before concrete is poured; a backfill inspection at least seven days after concrete is poured, which also requires an as-built survey before framing begins (§ 8-37); an electrical service inspection before the utility energizes the site (§ 8-38); framing and wiring inspection once the structure is framed, roofed and rough-wired but before insulation goes in (§ 8-39); underfloor and rough plumbing inspections (§§ 8-40, 8-41); insulation and slab inspections (§§ 8-42, 8-43); a final plumbing inspection during the occupancy inspection (§ 8-44); and the final or occupancy permit inspection itself under § 8-45, which requires heating, lighting, water and sanitary hookups, gutters, downspouts, steps, handrails, porches and exterior finish to be complete, plus final approval of well, septic and site development permits before a certificate of occupancy is released. Missing an inspection or building past a failed stage is treated like any other Building Code violation under Section 8-22.
