New Fence Installation in Byers, CO

New fence installation in Byers starts with a question a lot of suburban fence jobs skip: is the parcel zoned agricultural. Arapahoe County’s fence rules exempt most agricultural-zoned land from the standard height and setback requirements, and a large share of Byers properties sit in exactly that kind of zoning, so the first step on every Byers fence project is confirming the parcel’s zone district before quoting height or material.

A County Fence Permit Is Required Before Work Starts

Arapahoe County requires a fence permit from the Public Works and Development Building Division before anyone erects, constructs, enlarges, alters, or moves a fence anywhere in the county, including Byers. The rule applies to any fence enclosing a lot, or enclosing more than 15% of a zone lot’s area, and permit fees are set by the Board of County Commissioners and paid before the permit is issued.

We confirm the parcel’s zone district as the first step, because that answer determines which set of rules actually applies to the fence being planned.

Agricultural Zoning Changes the Rules for Many Byers Parcels

Fences on land zoned A-E, A-1, or RR-A are excluded from most of the county’s standard fence requirements as long as the land is used for agricultural purposes and the fence is kept properly maintained. That covers a real share of Byers-area properties, especially larger rural parcels with livestock, hay ground, or working outbuildings.

That exemption isn’t total, though. Corner-lot sight-triangle rules and the county’s general maintenance and nuisance-abatement authority still apply even on agricultural-zoned land, so an ag-exempt fence still has to stay clear of a corner sight line and still has to be kept in good repair.

Standard Height Limits Apply Outside the Ag Exemption

Where the standard rules do apply, front-yard fences generally can’t exceed 3 feet, and side- or rear-yard fences can be any of the county’s fence classes but can’t exceed 6 feet, not counting hedges. A side-yard fence can’t extend past the lot’s front building line, or the neighbor’s front building line, whichever is closer to the rear lot line, unless a 16-foot minimum sight-distance triangle is provided along with an 8-foot setback from the side corner property line.

Corner lots carry an additional rule: nothing over 3 feet tall, including a fence, sign, or plant growth, is allowed inside a 30-foot sight triangle measured from where the front and side lot lines meet.

Materials Fall Into Six Defined Classes

The county’s code defines six fence classes: Class 1 Masonry, Class 2 Ornamental Iron, Class 3 Chain Link with wire at least one-eighth inch in diameter, Class 4 Wood Picket that’s more than half open, Class 5 Solid at less than half open, and Class 6 Hedge made of living plant material. Barbed wire and electrified fencing are prohibited in most residential contexts, but are allowed on land zoned A-E, A-1, RR-A, RR-B, and a handful of other agricultural or industrial categories, provided any electrified sections are posted and, where required, built to specific height and construction standards above grade.

Given how many Byers properties fall into agricultural zoning, barbed wire around pasture or livestock areas is a real option there in a way it isn’t in a typical subdivision, and we account for that in the material conversation from the start.

Retaining Walls and Pool Barriers Follow Separate Rules

Any retaining wall built as part of a fence project that exceeds 4 feet in height, measured from finished grade on the low side, has to be designed by a Colorado-licensed structural engineer, with the engineer’s seal on the plans submitted for the fence permit. Retaining walls inside a 30-foot sight triangle can’t exceed 3 feet regardless of the engineering.

Where a fence is meant to enclose a pool, the barrier has to comply with the 2021 International Swimming Pool and Spa Code as adopted by the county, and it has to be in place, inspected, and approved before the pool can be filled with water. That’s a separate approval track from the general fence permit, and we plan for both when a pool is part of the project.

Utility Locates Matter More on Larger Rural Lots

Before any post hole gets dug, we request a utility locate through Colorado 811 so buried lines get marked ahead of excavation. On a Byers parcel with a well, septic system, or irrigation line running across the yard, a locate ticket for public utilities doesn’t necessarily catch every private line, so we also walk the fence route with the homeowner to identify anything that wouldn’t show up on a standard locate.

Long fence runs across open rural ground make this step more important, not less, since a single missed line can affect hundreds of feet of layout instead of a small suburban yard.

How We Sequence a Byers Fence Project

The sequence starts with confirming the parcel’s zone district and whether the agricultural exemption applies, then filing the county fence permit with the applicable class, height, and setback details for that zoning. Before digging, we request a Colorado 811 locate and walk the route for private utilities, wells, and septic lines that a public locate wouldn’t catch.

Post installation follows the approved layout, with corner sight-triangle clearances and any required setbacks maintained from the first post to the last. Gates, bracing, and any barbed-wire or electrified sections are finished to the county’s construction standards, and the completed fence is left in a condition that satisfies the county’s ongoing maintenance requirement.

Common Questions

Does every fence in Byers need a county permit?
In general, yes. Arapahoe County requires a fence permit before erecting, enlarging, altering, or moving a fence anywhere in the county, including Byers, for any fence enclosing a lot or more than 15% of a zone lot’s area.

Do agricultural properties in Byers still need to follow the standard fence height rules?
Not entirely. Fences on land zoned A-E, A-1, or RR-A and used for agricultural purposes are excluded from most standard height and setback rules, though corner-lot sight-triangle rules and maintenance requirements still apply.

How tall can a backyard fence be in Byers outside the agricultural exemption?
Where standard rules apply, side- and rear-yard fences generally can’t exceed 6 feet (not counting hedges), and front-yard fences generally can’t exceed 3 feet, with additional setback rules near corners.

Is barbed wire allowed on a Byers property?
It can be, on land zoned A-E, A-1, RR-A, RR-B, and certain other agricultural or industrial categories, subject to posting and construction requirements. It’s generally not allowed in standard residential zoning.
