Summary
The Kane County Zoning Ordinance sets no separate political-sign rule. Signs in residential and farming districts are limited to specific permitted types and small sizes. Content-based limits are unenforceable under the First Amendment, so a yard sign meeting size and setback standards is allowed.
Sign, one, not larger than twenty (20) square feet in area, pertaining to the sale, lease, or identification of the premises upon which it is located or the sale of farm products produced thereon.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-17: Code current through: Ord. 26-183, passed 4-14-2026).
Full Breakdown
Kane County regulates signs district-by-district in Chapter 25 rather than with a stand-alone political-sign ordinance. In the farming and residential districts the permitted on-site signs are limited (for example, one sign not larger than 20 square feet pertaining to sale, lease, or identification of the premises), and all signs must meet established setback provisions. Because Reed v. Town of Gilbert bars content-based sign restrictions, a residential political yard sign that complies with the applicable size and setback standards is permitted. There is no county permit for an ordinary residential yard sign; municipal rules apply inside cities.
Violations & Fines
Signs exceeding size limits, placed in the right-of-way, or violating setbacks may be removed by the county and cited as zoning violations.
