Caldwell, ID Swimming Pools & Spas: Pool Permits (2026)

Caldwell City Code 12-01-01 adopts the '2018 International Residential Code parts I through VI and IX, including appendix G' as published by the International Code Council and adopted by the State of Idaho/Idaho Building Code Board. Appendix G of the IRC covers swimming pools, spas and hot tubs, so a residential pool in Caldwell is built and inspected under that adopted building code through the city's Building Safety Division. A swimming pool is defined in zoning Code 10-01-10 as a water-filled enclosure (permanent or portable) more than eighteen inches (18') deep below the surrounding grade, or an above-surface pool more than thirty inches (30') deep, designed and used for swimming. Separately, zoning Code 10-12-03-1(3)C requires pools in all zoning districts to be set back ten feet (10') from all property lines. Under Code 12-01-05, building permit fees are set by the building official and based on the valuation of the work, with a plan-review deposit due at submittal rather than a fixed flat fee. Where the city code and the adopted building codes differ, Code 12-01-01(2) provides that the more restrictive standard applies. Confirm current submittal requirements and fees with the Caldwell Building Safety Division before starting construction.
