Schaumburg, IL Building Safety: Building Permits (2026)

4, any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building, or to install, alter, remove, convert, or replace an electrical, gas, mechanical, or plumbing system, must first apply to the community development department for a permit. The code exempts alterations, additions, replacements, or repairs valued under five hundred dollars that also meet chapter 154's size and location rules, or that cover less than one hundred square feet of siding or roofing or sixteen linear feet of fence, so long as the work isn't life-safety related and skips mechanical, electrical, plumbing, or fire alarm work; it also exempts routine decorating and single fixture, door, or window replacements that don't touch wiring, plumbing, or structure.

1 fixes how long a permit stays valid: one year for most residential work, one hundred eighty days for single-family sheds, fences, reroofs, porches, patios, driveways, sidewalks, decks, pools, siding, and detached garages, and two years for commercial and industrial permits. 3 requires plans sealed by a licensed Illinois architect or structural engineer whenever the cost or structural scope exceeds ten thousand dollars, a ten-thousand-dollar security bond or letter of credit for new single-family construction, and a refuse and recycling plan diverting at least thirty-five percent of construction debris, though single-family homes are excused from the thirty-five percent figure if they document what they recycled.
