STATE LICENSE
ConditionalIdaho Contractors Board — Division of Occ…
No Idaho statute licenses routine pool cleaning or water-chemistry service. Building or remodeling a pool is construction under Idaho Code § 54-5203(2), so it requires contractor registration with the Idaho Contractors Board (DOPL) on projects of $2,000 or more — $300,000 single-limit liability insurance, workers' compensation status, and a $120 application fee effective July 1, 2026.
Trade carve-outs apply at any job size: the HVAC chapter expressly lists pool heaters (§ 54-5003(3)), so installing or repairing them requires an HVAC certificate of competency; pool electrical work requires a DOPL electrical license (§ 54-1002). ISDA's Industrial, Institutional, and Structural Pest Control category lists swimming pools, so applying registered pesticide products to customers' pools may require an ISDA professional applicator license.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Idaho Code § 54-5213(1) bars cities, counties, and other local governments from running their own contractor registration or licensing programs (since January 1, 2007). They still issue building permits, and § 54-5209 requires the permit office to request your Idaho registration number and print it on the face of the permit — or mark it 'no contractor registration provided' for an exempt person — and the permit must be posted at the site. HVAC and electrical licensing are exclusively state (§§ 54-5015(2), 54-1002(5)), and pesticide rules are state-only (§ 22-3426).
The local offices section below names the exact permit desk for every Idaho county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Idaho's HVAC definition expressly includes pool heaters (§ 54-5003(3)) — heater work needs an HVAC certificate.
Cleaning and balancing water is not a licensed trade; building or remodeling a pool for others is registered contractor work at $2,000+.
ISDA's IP pest control category lists swimming pools among its sites; confirm with ISDA before applying pesticide products for hire.

Pending verification: Whether ISDA requires a professional applicator license for routine application of chlorine, algaecides, or other registered pool sanitizers by service companies (IP category lists swimming pools, but no ISDA statement on pool service was retrieved) · Whether replacing pool pumps and pool piping requires a plumbing certificate (not addressed in chapter 26 text reviewed) · Whether Idaho health rules require a certified pool operator for companies servicing public or semi-public pools · How DOPL's $120 initial registration fee squares with IDAPA 24.21.01.400, which lists the application (including original registration) at $60 'not to exceed' — presumed to be two aggregated annual fees for a biennial first term ('Annual fees may be aggregated for biennial licensure'), but not confirmed
