Caldwell, ID Swimming Pools & Spas: Fencing & Safety Requirements (2026)

Swimming pools fall under Caldwell's accessory use standards in Section 10-12-03-1(3), the same subsection setting the general 10-foot residential and 5-foot nonresidential setback for accessory uses. Rather than carve out a separate distance, the code singles pools out for a stricter, uniform rule: a pool in any zoning district in Caldwell, residential, commercial or otherwise, must be set back 10 feet from every property line, not just the rear or side lines an ordinary accessory use might use. The requirement for a physical barrier is not written as a standalone fence-height or gate specification in the zoning title; instead, Section 10-12-03-1(3)(C) provides that barriers around a pool are provided and regulated under the city's adopted building codes, and directs anyone applying the rule to the definition of 'swimming pool' set out in Section 10-01-10 of the zoning chapter.

That cross-reference means a homeowner installing a pool needs to check both the zoning setback in Section 10-12-03-1 and the barrier specifications in whichever edition of the adopted building code the city applies for enclosure height, self-closing and self-latching gate hardware, and alarm requirements, rather than finding those construction details spelled out a second time in the zoning title itself.
