Summary
Fort Collins requires a permit before building, altering, or repairing any residential swimming pool, spa, or aquatic recreation facility. The city administers pool construction under the 2024 International Swimming Pool and Spa Code, locally amended so that permits, fees, inspections, and appeals all follow the same procedures set out in the city's adopted Building Code.
Pursuant to the power and authority conferred on the City Council by Colorado Revised Statutes Section 31-16-202 and Article II, Section 7 of the Charter, the City Council has adopted the 2024 International Swimming Pool and Spa Code, published by the International Code Council, second printing (August 2024), as amended by the City, which shall have the same force and effect as though set forth in full herein... SECTION 105 PERMITS is deleted in its entirety and replaced with the following: SECTION 105 PERMITS. 105.1 General. All items related to permits shall be as determined in accordance with Section 105 of the adopted International Building Code, entitled "PERMITS."
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
City Council adopted the 2024 International Swimming Pool and Spa Code, second printing (August 2024), under City Code § 5-34, covering construction, alteration, movement, renovation, replacement, repair, and maintenance of pools, spas, and aquatic recreation facilities. Section 5-35 rewrites the code's administrative chapters so a Fort Collins pool project runs on Building Code procedure rather than the model code's own text: SECTION 105 PERMITS is deleted and replaced so that all items related to permits shall be as determined in accordance with Section 105 of the adopted International Building Code.
' Construction documents, temporary structures, service utility connections, and inspections are likewise cross-referenced to the corresponding IBC sections (107, 108, 110, 111) rather than restated. An applicant who disagrees with a permit denial or an interpretation of the code appeals to the Building Review Commission under the IBC's Section 113 'Means of Appeal' procedure, incorporated by SECTION 112 of the amended pool code. The Building Official (the 'code official') administers and enforces the code citywide, and Appendices are not separately adopted beyond what § 5-35 sets out.
Because the pool code borrows the Building Code's permit and fee machinery wholesale, a homeowner planning an in-ground or built-in pool or spa should expect the same plan-review, fee-schedule, and inspection sequence used for any other building permit in the city, not a separate track.
Violations & Fines
Working without the required permit, or violating approved construction documents or a code official's directive, is a civil infraction under Section 113.1 of the amended pool code, enforced through City Code § 1-15(f). Each day the violation continues counts as a separate offense, so an unpermitted pool build can generate a new violation daily until it is corrected or a permit is obtained.
