Summary
Fort Collins doesn't require a building permit for a fence 6 feet or shorter. City Code Section 5-30 amends the adopted 2024 International Residential Code so that Section R105.2 exempts 'fences not over 6 feet' from permitting, but a taller fence, or any fence inside a required zoning setback, still needs City sign-off.
R105.2 Work exempt from permit. Exemption from permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this code or any other laws or ordinances of this jurisdiction. Permits shall not be required for the following: Building: ... 2.Fences not over 6 feet (1829 mm) high.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Municipal Code: Supplement 155 | Transitional Land Use Code (for project before May 17, 2024): Supplement 61 | Traffic Code: Supplement 27).
Full Breakdown
' That provision lists a fence up to 6 feet (1,829 mm) high among more than a dozen minor projects, alongside detached sheds under 120 square feet or 8 feet tall, retaining walls under 4 feet, and decks under 200 square feet and 30 inches high, that residents may build without applying for a building permit from the Building and Zoning Director. Cross the 6-foot mark and the fence needs full building-permit review under the same chapter, Sections 5-26 through 5-30, which adopt the 2024 International Building and Residential Codes with City amendments.
19(A)(2); that zoning-permit layer applied to development applications and building permits submitted before May 17, 2024, so a project filed after that date should be checked against the current Land Use Code.
Violations & Fines
The exemption itself warns that skipping the building permit 'shall not be deemed to grant authorization for any work to be done in any manner in violation' of the code, per Section R105.2; the Building and Zoning Director can require an over-height or noncompliant fence to be removed, modified, or retroactively inspected. Unpermitted construction citywide can also be prosecuted as a misdemeanor under City Code Section 1-15, punishable by a fine and surcharge of up to $2,650, up to 180 days imprisonment, or both, with each day of the violation a separate offense.
