Summary

In Bonneville County's residential zones, no fence, wall or hedge over 3 feet tall is allowed within 15 feet of the front lot line, and corner lots keep a 40-foot clear-view triangle from any sight obstruction over 3 feet.

These county ordinances apply to unincorporated areas of Bonneville County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

FENCES AND CONTROLS FOR SIGHT OBSTRUCTION.

(A) In all residential zones, no fence, wall, hedge or other sight obscuring object or structure which is more than three feet in height shall be constructed or allowed to exist above said height within 15 feet of the front lot line.

Full Breakdown

062 sets the front-yard fence height limit: in all residential zones, no fence, wall, hedge or other sight-obscuring object or structure taller than 3 feet can be built or allowed to stand within 15 feet of the front lot line. Subsection (B) makes clear this rule doesn't authorize any structure, shrub, hedge or sight-obscuring object to violate any other part of the zoning chapter, so it works as a floor, not a substitute for other height or setback limits. 031: in any zone requiring a front yard, no obstruction over 3 feet can be placed on a corner lot within the triangular area formed by the street property lines and a line connecting points 40 feet from the intersection of those street lines.

That triangle rule carries two carve-outs: a reasonable number of trees pruned to at least 7 feet above curb or grade (or higher, whichever gives an unobstructed view), and pumps at gasoline service stations. 062 for all other front-yard fencing.

Violations & Fines

Erecting or maintaining a fence, wall or hedge over 3 feet tall within 15 feet of the front lot line, or placing any sight obstruction over 3 feet inside a corner lot's 40-foot visibility triangle, violates §§ 156.062 and 156.031. Violations of § 156.031 carry the penalty referenced at § 156.999: a $100 fine as an infraction, with each day of the obstruction counted as a separate offense.

Frequently Asked Questions

How tall can my front fence be in Bonneville County?
No more than 3 feet within 15 feet of the front lot line in residential zones, per § 156.062. Fences farther back from the front line, or in the side and rear yards, aren't capped by this particular section.
What is the corner-lot sight triangle rule?
Section 156.031 bars any obstruction over 3 feet within the triangular area formed by the street property lines and a line connecting points 40 feet from the street intersection, so drivers can see around the corner.
Can I plant a tall hedge on a corner lot?
Only if it's pruned to at least 7 feet above curb or grade, or high enough to leave an unobstructed view, whichever is greater; § 156.031 exempts trees maintained that way from the 3-foot corner sight-triangle limit.
