Building a fence in Commerce City, CO, involves more than choosing a design—it requires navigating zoning regulations, permit processes, HOA guidelines, and site conditions. Whether you’re installing a privacy fence, enhancing your front yard, or securing a pool, this guide walks you through every step to ensure your fence is compliant, durable, and aesthetically pleasing. Let Denco Fence handle the details for a stress-free experience.
🏡 Do You Need a Fence Permit in Commerce City?
Yes—in Commerce City, all fences require a building permit, regardless of height, whether they are new, replacements, or repairs. This applies to residential, commercial, and industrial properties to ensure compliance with the Land Development Code (LDC), safety standards, and neighborhood aesthetics.
✅ Permit Application Process
Homeowners or contractors can apply for a permit through Commerce City’s eTRAKiT Permitting Portal. Homeowners doing their own work on their primary residence don’t need a contractor’s license but must submit a complete application, including a site plan. For rental properties, a letter of permission from the property owner may be required.
⌛ How Long Does It Take to Get a Permit?
Standard fence permits are typically processed within 3–7 business days. Projects in Planned Unit Developments (PUDs), floodplains, or requiring height exceptions may take 2–4 weeks due to additional reviews. Contact the Building Safety Division at 303-289-3790 or buildingpermits@c3gov.com for assistance.
⚠️ What Happens If You Skip the Permit?
Building without a required permit can result in:
- Fines or code violation notices
- Mandatory fence removal or modification
- Complications during property sales or inspections
📏 Fence Height & Placement Rules
Commerce City enforces specific height and placement rules under the Land Development Code to maintain safety, visibility, and neighborhood aesthetics.
🧱 Height Limits by Location
-
Front Yard: Maximum height of 4 feet
-
Back Yard: Maximum height of 6 feet
-
Side Yard: Maximum height of 6 feet
-
Corner Lot: Maximum height of 3 feet (within visibility triangles)
Note: Fences exceeding 6 feet require a height exception processed through the Planning Division. Fences in front yards must be at least 50% open (e.g., open rail or picket) and no taller than 4 feet. Visibility triangles at intersections or driveways limit fences to 3 feet. Check zoning with the eTRAKiT Portal.
🔀 Shared Property Lines
You may build directly on a shared property line with your neighbor’s written consent, per Colorado’s Good Neighbor Fence Law (Colo. Rev. Stat. 35-46-112). Without consent, the fence must be within your property line, typically with a 1–2 foot setback. Written notification of fence plans (dimensions, materials, costs) with a 30-day response period is recommended to avoid disputes.
🚧 Special Considerations
- Retaining Walls: Fences on retaining walls count toward total height and may require engineering review if exceeding 6 feet.
- Visibility Triangles: Fences over 3 feet are prohibited in visibility triangles at intersections, driveways, or alleys to ensure safe sightlines.
- Public Rights-of-Way: Fences along streets or sidewalks must have the finished side facing outward and be set back to avoid encroachment.
- Easements: Fences in utility easements are subject to removal if access is needed. Contact the Planning Division at 303-227-8777 to confirm easement locations.
- Floodplains: Fences in floodplains require a Floodplain Development Permit, reviewed by the Public Works Engineering Division.
- Pool Fencing: Pools require fences with self-closing, self-latching gates at least 4 feet high, per safety regulations.

- Wait for Approval: Standard permits take 3–7 business days; complex reviews may take 2–4 weeks.

🛠 Choosing Fence Materials & Construction Tips
Selecting materials that comply with Commerce City’s codes and withstand its climate (snow, wind, sun) is essential.
✅ Allowed Materials in Most Areas
- Open rail, split rail, separated picket, chain-link, or wrought iron (approved for front yards)
- Wood or vinyl privacy fences (side/back yards)
- Composite materials (e.g., Trex, eco-friendly)
- Solid masonry base (max 2 feet) with decorative open-style material above
🚫 Restricted or Prohibited Materials
- Barbed wire or metal picket prongs (allowed only in agricultural/industrial zones with warning signs and setbacks)
- Chicken wire, corrugated metal, fabric, fiberboard, plywood, or tarps
- Opaque fences in front yards without a principal structure
🔧 Best-Build Practices
- Post Depth: Set posts 24–30 inches deep (below the frost line) in concrete to prevent shifting.
- Fasteners: Use galvanized or exterior-grade screws/nails to resist rust.
- Spacing: Ensure minimum 2-inch picket spacing for open-style fences in front yards.
- Vinyl/Composite: Reinforce posts with steel and ensure a level base to prevent warping.
- Construction Site: Surround open excavation sites with a 6-foot fence to prevent unauthorized access.
🧰 Material Maintenance Tips
- Wood: Seal or stain every 2–3 years to prevent rot and UV damage.
- Vinyl: Clean regularly to avoid discoloration; avoid extreme heat exposure.
- Composite: Higher cost but minimal upkeep and eco-friendly.
- Wrought Iron: Apply rust-resistant coatings to extend lifespan.
💰 Cost Breakdown & Gate Pricing
Fence costs in Commerce City vary based on materials, labor, and site conditions:
- Labor: ~50% of total project cost
- Materials: Wood and vinyl are cost-effective; composite and wrought iron are pricier
- Permit Fees: $23.50 for projects valued at $500 or less, plus 4.5% use tax on materials; higher fees for larger projects
- Prep Work: Removing old fences, grading, or stump removal may add $3–$5 per foot

⚠️ Avoid These Common Fence Mistakes
Avoid these pitfalls to save time, money, and headaches:
- Skipping 811: Digging without marking utilities is illegal and dangerous.
- Ignoring Property Lines: Confirm boundaries with a survey to avoid disputes.
- Exceeding Height Limits: A 6-foot fence in the front yard or over 3 feet in visibility triangles violates code.
- Using Prohibited Materials: Barbed wire or opaque fences in front yards will trigger violations.
- Building in Easements: Fences in utility easements may need removal.
- Neglecting Pool Safety: Pools require self-closing, self-latching gates at least 4 feet high.
🏠 Real-World Example
A Commerce City homeowner installed a 7-foot chain-link fence in their front yard without a permit, unaware of the city’s permit requirement and 50% open rule for front yards. The city issued a violation notice. Denco Fence secured the permit, redesigned the fence with an open-rail style, and completed the project, avoiding fines.
🧩 Commerce City Variance & Exceptions
Need a taller fence (e.g., over 6 feet) or non-standard design? Apply for a height exception through the Planning Division. Requirements include:
- Demonstrating a unique hardship (e.g., privacy or safety needs)
- Proving no negative impact on neighbors
- Submitting a traditional height exception application, processed as an administrative review
Contact the Planning Division at 303-227-8777 or planning@c3gov.com.
