Building a fence in Westminster, CO, involves more than choosing a design—it requires navigating zoning regulations, permit processes, HOA guidelines, and site-specific 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 Westminster?
Yes—in Westminster, 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 Westminster Municipal Code, safety standards, and neighborhood aesthetics.
✅ Permit Application Process
Homeowners or contractors can apply for a permit through Westminster’s Online Permitting Portal. Homeowners doing their own work must submit a complete application, including a site plan. For rental properties, a letter of permission from the property owner may be required if the work is not performed by the homeowner.
⌛ How Long Does It Take to Get a Permit?
Standard fence permits are typically processed within 5–10 business days. Projects in Planned Unit Developments (PUDs), floodplains, or requiring variances may take 2–4 weeks due to additional reviews. Contact the Building Division at 303-658-2075 or buildingpermits@cityofwestminster.us 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
Westminster enforces specific height and placement rules under the Westminster Municipal Code (Section 11-4-27) 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 standard heights (e.g., 8 feet for noise mitigation along arterial streets) require a variance or special approval. Visibility triangles at intersections or driveways limit fences to 3 feet to ensure safe sightlines. Check zoning with Westminster’s Interactive Zoning Map.
🔀 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 safety.
- Public Rights-of-Way: Fences adjacent to public rights-of-way (e.g., streets, sidewalks) must have the finished side facing outward.
- Easements: Fences in utility easements are subject to removal if access is needed. Contact the Planning Division at 303-658-2092 to confirm easement locations.
- Floodplains: Fences in floodplains require a Floodplain Development Permit, reviewed by the Public Works and Utilities Department.
- Pool Fencing: Pools require fences with self-closing, self-latching gates at least 4 feet high, per safety regulations.

🛠 Choosing Fence Materials & Construction Tips
Selecting materials that comply with Westminster’s codes and withstand its climate (snow, wind, sun) is crucial.
✅ Allowed Materials in Most Areas
- Cedar or redwood (durable, natural wood)
- Vinyl privacy fences (low maintenance)
- Composite materials (e.g., Trex, eco-friendly)
- Wrought iron or ornamental metal (ideal for decorative areas)
- Chain-link (allowed in side/back yards, often restricted in front yards)
🚫 Restricted or Prohibited Materials
- Barbed wire or electrically charged fences in residential zones
- Chicken wire, plywood, or other non-durable materials visible from public streets
- Hazardous or non-standard materials not meeting structural requirements
🔧 Best-Build Practices
- Post Depth: Set posts 24–30 inches deep (below the frost line) in concrete to prevent shifting in freeze-thaw cycles.
- Fasteners: Use galvanized or exterior-grade screws/nails to resist rust.
- Spacing: Ensure proper spacing for rails and pickets to allow airflow and drainage, especially for wood fences.
- Vinyl/Composite: Reinforce posts with steel and ensure a level base to prevent warping.
- Maintenance: Fences must be structurally sound, with no leaning or missing pickets, to avoid code violations.
🧰 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 Westminster 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: $50–$150, based on project valuation
- Prep Work: Removing old fences, grading, or stump removal may add $3–$5 per foot
Gate Costs:
- Side gate: $150–$400
- Driveway gate: $400–$1,500+, especially with automation
⚠️ 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 plywood visible from streets 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 Westminster homeowner installed a 7-foot fence without a permit, unaware of the city’s requirement for all fences. The city issued a violation notice, requiring a permit and adjustments to meet visibility triangle rules. Denco Fence secured the permit, redesigned the fence to comply, and completed the project, avoiding fines.
🧩 Westminster Variance & Exceptions
Need a taller fence (e.g., 8 feet for noise mitigation) or non-standard design? Apply for a variance through Westminster’s Board of Adjustment. Requirements include:
- Demonstrating a unique hardship (e.g., traffic noise or privacy needs)
- Proving no negative impact on neighbors
- Attending a public hearing to address concerns
Contact the Planning Division at 303-658-2092 for details.
🏡 Dealing with HOAs & Neighborhood Rules
HOAs in Westminster may impose stricter rules than city codes, including:
- Height and material restrictions
- Color or design standards
- Setback requirements
- Approval from architectural committees (may take 15–30 days)
Obtain written HOA approval before construction, even if your fence complies with city regulations. Check covenants with the Jefferson County Clerk or Adams County Clerk.
🤝 Westminster’s Good Neighbor Tips
Colorado’s Good Neighbor Fence Law promotes cooperation:
- Notify neighbors in writing before building on shared property lines, detailing plans (location, materials, costs).
