Summary
Nearly any construction, alteration, or system work on a building in unincorporated Rock Island County needs a permit first. Section 150.01(A)(1) requires an owner or authorized agent to apply to the Director of Zoning and Building and get the permit before construction, alteration, demolition, or an electrical, mechanical, or plumbing change begins.
(1) Permit required. Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert, or replace any electrical, mechanical, or plumbing system, the installation of which is regulated by codes adopted by the county, or to cause any such work to be done, shall first make an application to the Director of Zoning and Building and obtain the required permit.

Full Breakdown
01(A)(1), the county's threshold "Permit required" clause, covers essentially any building work: anyone who intends to "construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building or structure," or to touch an electrical, mechanical, or plumbing system regulated by the county's adopted codes, must first apply to the Director of Zoning and Building and obtain the permit before starting. 22. 01(A)(3), post a $10,000 compliance bond before the office of Zoning and Building Safety will issue permits to them. 01(A)(4) before registering.
Violations & Fines
Starting work before the permit issues triggers a penalty fee equal to the full permit cost for the entire project, not just the unpermitted portion, under §§ 150.16(G), 150.17(E), and 150.99(B)(2). A second unpermitted start within a five-year rolling period escalates to the stop-work and referral powers in § 150.16(H): the Building Official can shut down that job and any other project the same contractor holds in the county, and refer the matter for § 150.99 fines of $25 to $1,000 per day.
