Summary
In unincorporated Boone County, Indiana, fences under six feet do not need an improvement location permit under Boone County Code § 157.140(C).

(C) Fences under six feet in height shall not require an improvement location permit.
Full Breakdown
Fences are listed among the accessory structures the county permits in every zoning district, and § 157.021(C) allows them to be installed in any required yard, including front yards, without an improvement location permit (ILP). Section 157.140(C) sets the six-foot threshold: fences at or above six feet fall outside that exemption and require an ILP from the Area Plan Commission Director, along with the filing fee listed in the chapter's Appendix A. On corner lots, § 156.072(J)(1) requires every secondary subdivision plat to carry a restrictive covenant prohibiting any fence, wall, hedge, tree or shrub planting between three and 12 feet above the street from standing inside the triangular area formed by the street right-of-way lines and a line connecting points 40 feet from the intersection of the street lines (measured from the extended right-of-way lines at a rounded corner).
Pools carry their own fence rule: § 157.021(F)(3) requires in-ground swimming pools to have a five-foot-high fence around the pool area or a mechanical pool cover. The Director of the Area Plan Commission administers and enforces these standards, with appeals running to the Board of Zoning Appeals under § 157.160.
Violations & Fines
Starting construction on a fence requiring an ILP before obtaining one triggers an early-bird fee under the fee schedule per § 157.165(B)(1), and the owner, tenant or anyone assisting in the violation can each be charged separately. General zoning violations, including a sight-triangle obstruction, carry civil penalties of not more than $500 per day under § 157.165(C), and the APC or BZA can sue for an injunction to force removal under § 157.165(A).
