    Boulder Fence Regulations

    Boulder Fence Regulations

    Building Permits are not required for fences 6 feet in height and under from existing grade (i.e., not on a berm or platform). However, fences of any height in the floodplain require a permit. See Standards for Fencing in a Floodplain on page 2. Fences over 6 feet in height require a building permit for construction, and must meet setback requirements for the zoning district in which they are located. Fences over 6 feet may require plans for the footings and foundation that are prepared and stamped by a professional engineer. All fence components, including footings, must be on the fence owner’s property. Fences are not allowed within the road right-of-way.

    Setback Requirements Setback

    • Requirements vary by zoning district and road. To determine specific setback requirements for your parcel, please check with a planner at the Land Use Department by emailing planner@bouldercounty.org or calling 303-441-3930.

    Road Intersections

    • Fences of any height can not interfere with the sight triangle at intersections. The sight triangle varies based on the posted speed of the road. Please contact the Boulder County Transportation Department by emailing transportation@bouldercounty.org or calling 303-441-3900.


    The county does not prohibit construction of fences in utility easements, but the fence installer and/or property owner assumes risk by doing so. Call the local utility companies for information on utility line locations. In addition, make sure that any fence in or adjacent to a storm drainage easement or swale does not impede the normal flow of stormwater.

    Wildlife Safe Fencing

    Specific requirements for wildlife safe fencing might have been required through a Land Use review process (Site Plan Review, etc.). If your parcel has been through a Land Use review process, check the conditions of approval to see if there is a requirement for wildlife safe fencing.


    Subdivisions may have provisions more restrictive than those above. Please check with your homeowners association and/or your subdivision’s covenants prior to commencing construction. The county does not enforce subdivision covenants.

    Other Important Fencing Information

    The term fence does not include retaining walls. Also, fences built around a developed use, such as a tennis court or outdoor eating area must meet other zoning, land use, and Building Code standards. Retaining walls and masonry fences must meet the structural design standards of the International Building Code.

    Great experience with a company that has served Boulder and surrounding communities for many years. Received a fair, accurate estimate… a firm start date that the company honored… efficient installation and full clean up. With all the new construction on the NW side of town, fencing services are in demand and it is not cheap… but if you want a reputable company with a history of keeping its commitments, A-T Contractors is a great choice.

    These guys were phenomenal, reasonably priced, and professional. They're definitely not monkeys in a truck looking for a quick buck. The care and quality of work speaks for itself. They made sure I stayed informed throughout the process, and that I was happy with the work before they sent a bill. I cannot recommend them enough.

    These guys were great! Kyle was very forthright in the scheduling and pricing. The team was extremely professional, finished the job in a timely fashion (1.5 days as promised) and did an excellent job constructing our fence. Our gate is on a hill so they had to custom build it and it really looks fantastic. I would definitely recommend!
