Summary
In unincorporated Weld County, a fence under six feet tall isn't a regulated "Structure" at all, so it can go right up to the property line with no zoning review. Once a fence reaches six feet, County Code Section 24-1-40 reclassifies it as a Structure, which then must sit behind the same front, side and rear setback lines Chapter 23 sets for your zone district.
Structure: Anything that is built, constructed or erected, an edifice or building of any kind, or any piece of work artificially built up or composed of parts joined together in some definite manner, but not including fences or walls used as fences less than six (6) feet in height, poles, lines, cables or distribution facilities of public utilities. Structures shall comply with requirements set forth in Chapter 23 of this Code, including required zoning setbacks and offsets and shall be installed in accordance with the building requirements set forth in Chapter 29 of this Code.
Subdivider or developer: Any person, firm, partnership, joint venture, association or corporation who shall participate as owner, promoter, developer or sales agent in the planning, platting, development, promotion, sale or lease of a subdivision. See also applicant.

Full Breakdown
Weld County's subdivision definitions chapter, Section 24-1-40, draws the line at six feet. The Code defines "Structure" as anything built or erected "but not including fences or walls used as fences less than six (6) feet in height." That carve-out means a four-foot picket fence, a five-foot livestock fence, or any fencing shorter than six feet along a property line in the unincorporated county isn't subject to the zoning setbacks in Chapter 23 at all: no minimum distance from the front, side or rear lot line applies to it.
Cross six feet, though, and the fence becomes a "Structure" under the same section, and the Code is explicit that Structures "shall comply with requirements set forth in Chapter 23 of this Code, including required zoning setbacks and offsets." Practically, a six-foot-plus fence, wall or masonry screen has to respect whatever front, side and rear yard setback distances apply to your zone district under Chapter 23, Article III, the same as a shed or detached garage would. The Department of Planning Services administers those setback distances by zone district, and each district (Agricultural, Residential, Commercial, Industrial and the overlay districts) carries its own bulk-requirement table.
The six-foot threshold does double duty: it also ties the fence into the building requirements of Chapter 29, since Section 24-1-40 says Structures must be "installed in accordance with the building requirements set forth in Chapter 29 of this Code." A fence at or above six feet still doesn't need a building permit, fences are exempt work under Section 29-2-20(G), but it does need to sit inside the applicable zoning setback.
Violations & Fines
Building a six-foot or taller fence inside the required Chapter 23 setback is a zoning violation the Department of Planning Services can enforce administratively, typically by ordering the fence relocated or shortened below six feet to fall outside the Structure definition. Because Section 107.3.1.1 requires a Planning Services zoning-compliance sign-off before any other County permit is released, an unresolved fence-setback violation can hold up building permits for other work on the same parcel until it's corrected.
