Summary
Weld County does not require a building permit to put up a fence in the unincorporated county. Section 29-2-20(G) lists fences as work exempt from permit, with one exception: a fence that serves as a swimming pool barrier still needs one, since pool safety barriers are regulated separately.
Amend Section 105.2 Work exempt from permit, to edit and/or insert the following items: Building:1.One-story detached accessory buildings, provided that:a.The floor area does not exceed two hundred (200) square feet.b.The accessory building is used as a tool and storage shed, playhouse or similar use.2.Fences, other than swimming pool barriers.

Full Breakdown
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.
Violations & Fines
Skipping the barrier permit on a new pool fence is what actually draws enforcement here, not building an ordinary yard fence. The Weld County Building Department can issue a stop-work order and withhold final approval on the pool itself until the required barrier permit and inspection are completed, since Section 105.2 pulls pool barriers out of the general fence exemption.
