Kirkland enforces zoning violations, including oversized retaining walls, through the general civil enforcement chapter, KMC 1.12.045. Fines run $100 per day for days 1 through 15 of noncompliance, $250 per day for days 16 through 30, and $500 per day from day 31 onward, capped at $50,000 per violation. A modification decision by the Planning Official may be appealed under Process I, KZC 145.60 through 145.110, within the appeal window set by that chapter.

Height Limits

Fences in Kirkland can be up to 6 feet tall almost anywhere on a lot, but not within 15 feet of a street curb unless a survey fixes the property line, and single-family or middle housing fences in the required front yard along a neighborhood access or collector street are capped at 3.5 feet, under KZC 115.40(1).

Key details: General fence height cap: 6 feet. Front yard cap (collector streets): 3.5 feet. Setback from street curb: 15 feet unless surveyed. Fences over 6 ft: barred from setback yards. Arterial-adjacent cap: 3.5 ft within 3 ft of line.

An oversized or misplaced fence is a zoning violation the Planning and Building Department enforces under KMC Chapter 1.12. The city can issue a notice and order requiring the fence be lowered or relocated, and unresolved violations draw civil fines starting at $100 per day, escalating to $500 per day after 30 days, capped at $50,000 per violation under KMC 1.12.045.

Material Restrictions

Barbed wire is barred in Kirkland except when it tops a fence or wall that's already at least 6 feet tall, and free-standing electrified fences are banned outright except to contain large domestic animals, under KZC 115.40(2)-(3). Any permitted electric fence needs UL-listed components, must sit 18 inches inside a wood fence, and needs warning signs every 15 feet.

Key details: Barbed wire: only atop a fence/wall 6+ ft. Electrified fences: banned except large domestic animals. Electric fence components: must be UL/agency listed. Wood fence offset: 18 inches inside. Warning signs: 36 sq in, every 15 ft.

A barbed wire fence under six feet, or an unauthorized electrified fence, is a zoning violation the Planning and Building Department enforces under KMC Chapter 1.12. The city can order the fence removed or brought into compliance, and unresolved violations draw civil fines of $100 to $500 per day of noncompliance, capped at $50,000 per violation under KMC 1.12.045.

This is one of the stricter rules in Kirkland's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Kirkland's fence regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Kirkland is broadly strict or permissive.

These rules come from Kirkland's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
