Weld County, CO Fence Regulations: Fence Permit Requirements (2026)

When Weld County adopted the 2024 International Building Code by Ordinance 2026-05, it amended IBC Section 105.2, "Work exempt from permit," to add a local exemption list. Item 2 on that list reads simply "Fences, other than swimming pool barriers," placed alongside other minor work the County doesn't require paperwork for: small tool sheds under 200 square feet, oil and gas facility equipment, public utility towers, re-roofing and residing, and freestanding signs under ten feet.

The exemption applies without regard to fence height, material or location on the lot: a four-foot picket fence and an eight-foot livestock fence both skip the building-permit process under this list. That's a separate question from whether the fence has to sit behind a zoning setback; a fence six feet or taller is still treated as a "Structure" under Section 24-1-40 and has to meet Chapter 23's setback requirements, it just doesn't need a Building Department permit application to do it.

The one carve-out is a fence built as a swimming pool barrier. Because pool enclosures are safety devices regulated under the International Swimming Pool and Spa Code adopted at Section 29-2-95, a barrier fence around a pool falls back under the normal permit requirement rather than the general fence exemption.
