Understanding Longmont's Fence Regulations
Before you start planning your fence build, it's crucial to familiarize yourself with the City of Longmont's specific codes and zoning requirements. Adhering to these rules from the start prevents costly corrections and ensures your new fence is compliant.
Height and Location Rules: The regulations differ significantly based on where your fence will be located on your property 1.
- Front Yards: Fences cannot exceed 42 inches (3.5 feet) in height. Furthermore, they must be at least 50% "open" or transparent-meaning solid privacy fences are not permitted in front yards 1 2.
- Rear and Side Yards: For standard residential lots, solid privacy fences are allowed up to a maximum height of 6 feet (72 inches) 1.
- Greenways and Special Areas: Properties adjacent to greenways or drainage corridors are subject to stricter rules, such as a maximum height of 48 inches for primary greenways. Always check the specific requirements for your property 1 2.
Other Key Requirements:
- Finished Side: The smooth, "finished" side of the fence must face outward toward public areas and neighboring properties 1.
- Prohibited Materials: Chain-link or woven-wire fences are generally prohibited in front yards, except for temporary construction fencing 1.
- Property Lines: Your fence must be built entirely within your property lines. Encroaching on a neighbor's property or a public easement can lead to disputes and required removal.
A Guide to Fence Materials for Longmont Homes
Choosing the right material is a balance of aesthetics, budget, maintenance, and function. Longmont's climate, with its sunny days, seasonal snow, and potential for hail, should influence your decision.
Privacy Fence Options
These styles are ideal for backyards, creating secluded outdoor living spaces.
- Wood Fencing: A classic choice offering a natural, traditional look. Cedar and pressure-treated pine are common. Wood provides excellent privacy but requires regular staining or sealing to protect against Colorado's UV rays and moisture 3 1. It's a popular mid-range option for its aesthetic versatility.
- Vinyl Fencing: Known for its durability and minimal upkeep. Vinyl won't rot, warp, or need painting, making it a strong contender for low-maintenance living. It comes in various styles and colors, including options that mimic wood grain 3 4.
- Composite Fencing: Made from a blend of wood fibers and recycled plastics, composite offers the look of wood with even greater resistance to rot, insects, and fading. It's a modern, eco-friendly option that requires little maintenance beyond occasional cleaning 3.
Decorative and Security Fence Options
These are often used for front yard delineation, pool safety, or adding architectural interest.
- Aluminum Fencing: Provides the elegant look of wrought iron but is lighter, rust-resistant, and typically more affordable. It's an excellent choice for decorative borders that require little upkeep 1 4.
- Wrought Iron Fencing: Offers a premium, highly durable, and secure option. While it provides an open view, it is one of the more expensive materials and may require periodic painting to prevent rust 4 5.
- Chain-Link Fencing: The most budget-friendly and transparent option, often used for rear yards, dog runs, or commercial properties. It's functional and durable but is not permitted in Longmont's front yards for residential use 1.
Cost Considerations for Fence Installation
The total cost of your fence project in Longmont depends primarily on the material chosen, the linear footage, and the complexity of the terrain. Prices are typically quoted per linear foot, installed.
Here's a general overview of cost ranges per linear foot for different materials 3 4 6 7:
- Chain-Link: $10 - $20
- Wood: $25 - $45
- Vinyl/Composite: $25 - $60
- Aluminum: $30 - $50
- Wrought Iron: $35 - $70+
Remember, these are estimated ranges. The final price for your specific project will include factors like gates, post caps, terrain grading, and the contractor's labor rates. Always obtain detailed, written quotes from local installers.

The Essential Pre-Installation Checklist
A successful fence installation starts with thorough preparation. Following these steps will streamline the process and help avoid legal or logistical issues.
- Call 811 Before You Dig: This is a non-negotiable first step. Colorado state law requires you to contact 811 at least three business days before any excavation to have underground utility lines marked for free. This ensures safety and prevents damaging gas, water, or electrical lines 8 9 7.
- Verify Your Property Lines: Do not rely on existing fences or landmarks. Obtain a copy of your property's plot plan or survey to accurately identify your boundaries and any easements. Building on a neighbor's property is a serious and costly error 8 5.
- Check HOA Covenants: If your property is part of a Homeowners Association, review its CC&Rs (Covenants, Conditions, and Restrictions). HOAs often have rules about fence styles, materials, colors, and heights that can be more restrictive than city codes 9.
- Apply for Necessary Permits: In Longmont, a building permit is required for any fence over 6 feet in height. The permit application process involves submitting your plot plan and fence details to the Building Inspection Division for review 8 5. Securing a permit ensures your project is inspected and meets all structural and safety codes.
- Discuss with Neighbors: As a courtesy, inform adjoining neighbors of your plans. While not always legally required, this fosters good community relations and can help clarify the placement of the boundary line.
Hiring a Professional Fence Contractor
While a DIY fence project is possible, hiring a professional installer offers significant advantages, especially for ensuring compliance with local codes and achieving a durable, high-quality result.
What to Look For:
- Local Experience: Choose a contractor familiar with Longmont's specific regulations and soil conditions.
- Licensing and Insurance: Verify the company holds appropriate Colorado contractor licenses and carries both liability and workers' compensation insurance.
- Portfolio and References: Review past projects similar to yours and ask for references from recent clients in the area.
- Detailed Written Estimate: A reputable pro will provide a clear, itemized quote that includes materials, labor, permit fees, and a projected timeline.
- Warranty: Ask about warranties on both materials and workmanship.
A professional can handle the entire process-from navigating permits and calling 811 to setting posts perfectly plumb and ensuring the finished side faces correctly-saving you time and potential headaches.
Maintaining Your Longmont Fence
Protect your investment with proper maintenance tailored to your material.
- Wood: Inspect annually for rot, insect damage, or loose boards. Re-stain or seal every 2-3 years to protect from sun and moisture.
- Vinyl & Composite: Clean periodically with soap and water to remove dirt and mildew. Avoid abrasive cleaners that can scratch the surface.
- Metal (Aluminum/Wrought Iron): Check for rust spots, especially after winter. Touch up paint on wrought iron as needed. Aluminum generally only needs rinsing.
- All Fences: Keep the base of the fence clear of soil and mulch to prevent moisture retention and rot. Trim back plants and vines that can trap moisture or cause damage.
