Longmont, CO Swimming Pools & Spas: Pool Permits (2026)

Longmont adopted the 2021 International Swimming Pool and Spa Code by reference under Ordinance No. O-2021-65, Section 8, effective November 30, 2021, and then rewrote several of its administrative sections. Section 16.28.040 replaces the model code's Section 105.3 on construction documents: submittal documents, consisting of construction documents and other data, must be submitted per the city's requirements with each permit application, and those construction documents must be prepared by a registered design professional licensed in Colorado unless the project is otherwise exempt under C.R.S. § 12-120-403. A companion section, 16.28.050, requires the building official to approve the submitted plans in writing or with a "Reviewed for Code Compliance" stamp, keep one set on file, and return the other set to be kept at the worksite for inspection.

Permit fees are not fixed in the code; Section 16.28.060 sets them by resolution of the city council, updated from time to time. If a permit is later abandoned before any work begins, Section 16.28.070 lets the permittee forfeit the permit and recover 80 percent of the fee paid, or 80 percent of a plan-review fee if the application is withdrawn before review concludes, provided the refund request is filed within 180 days of payment.

Violations run through Section 16.28.090, which rewrites Sections 113.1 through 113.4: building or maintaining a pool without a valid permit is unlawful, each day of a violation is a separate offense punishable under Chapter 1.12 of the Longmont Municipal Code, up to a $500.00 fine and 90 days in jail, and the city can also pursue the violation as a public nuisance in court. Appeals of a permit denial or code interpretation go to the master board of appeals under Chapter 16.30, per Section 16.28.080.
