| Building Permit (Room Addition) | Any building addition requires a building permit (handout 671 "permit required" list). Zoning: must meet the district principal-building setbacks / coverage / height (§ 3). A project in a mapped floodplain is governed by the county Stormwater Management Ordinance + FEMA (the Flood_Hazard_Areas_2026 overlay). | Kendall County Planning, Building & Zoning (PBZ) |
| Building Permit (Basement / Interior Remodel) | An interior remodel / basement finish requires a building permit (handout 671 lists Remodeling). No exterior zoning change; egress/energy per the adopted IRC (Ch. 8). Electrical / plumbing / mechanical sub-permits are county-filed as scope requires. | Kendall County Planning, Building & Zoning (PBZ) |
| Building Permit (Deck) | Any deck requires a building permit (deck is on the handout 671 "permit required" list). An attached deck is a permitted obstruction in side/rear yards only (§ 4:05.B); a detached deck beyond that must meet the district principal setbacks (§ 3). An attached deck built with a new house is bundled into the house fee (§ 8-46(b)(1)). | Kendall County Planning, Building & Zoning (PBZ) |
| Building Permit (Detached Garage) | A detached garage requires a building permit (accessory structure). Zoning: § 4:05.C accessory placement (>=5 ft side/rear, A-1 >=10 ft; >=10 ft from the main building) + the § 4:05.E rear-yard height limits by district; footprint <=70% of the principal in R-5/R-6/R-7 (§ 4:05.F). | Kendall County Planning, Building & Zoning (PBZ) |

How to use this Kendall County, IL page
Illinois has no single statewide residential building code — municipalities (many home-rule) adopt and enforce their own codes. Statewide minimums include the Illinois Plumbing Code (IDPH, licensed plumbers required), the Illinois Energy Conservation Code, and the Illinois Accessibility Code. Zoning, signs, fences, and right-of-way permits are entirely local.
- Start with the parcel location. County authority can differ inside the same county depending on whether the site is in an incorporated city, village, town, or unincorporated area.
- Use this page as a readiness checklist before any phone calls so you can submit complete, accurate information to the right office.
- Flag overlays early—shoreland, floodplain, roads, drainage, septic, and access approvals can add extra approvals that are easy to miss.
- Gather owner information, a rough site plan, and project scope details before contacting agencies.
- Validate the final office list with Permit Check once your parcel and project context are captured.
