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."

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.

Frequently Asked Questions

Do I need a permit to build a pool in Fort Collins?
Yes. City Code § 5-34 adopts the 2024 International Swimming Pool and Spa Code for all pool and spa construction, and § 5-35 requires that permits for that work follow Section 105 of the city's adopted International Building Code, the same process used for other building permits.
What does a Fort Collins pool permit cost?
Fees are not set in the pool code itself. Section 5-35 directs that permit fees for swimming pool and spa work follow Section 109 of the adopted International Building Code, so the fee is calculated the same way as for other building permits in the city.
What happens if I build a pool without a permit?
Unpermitted pool construction or work that departs from approved plans is a civil infraction under Section 113.1 of the amended pool code, punishable under City Code § 1-15(f). Each day the violation continues is a separate offense, so the exposure grows the longer the work stays unpermitted.
Can I appeal a denied pool permit?
Yes. Section 5-35 routes appeals of permit denials or code interpretations to the Building Review Commission through Section 113, 'Means of Appeal,' of the adopted International Building Code, the same appeal path used for other building permit disputes in Fort Collins.
