Pool & Spa Contractor

There is no Colorado state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Colorado has no statewide general or specialty contractor license of any kind (confirmed structural fact, not merely an absence of reciprocity — there is no state license to reciprocate into). Pool/spa contracting, like general contracting, is licensed purely at the municipal/county level, and municipalities generally do not honor each other's local licenses, let alone out-of-state ones. Only electricians and plumbers are licensed statewide through DORA. A pool contractor moving to Colorado from another state must separately qualify with each city/county where they intend to work; there is no state authority to grant any waiver.

There is no Delaware state licence for this trade to reciprocate. A contractor licence applies above $50,000 (general contractor license threshold; pool work is not separately classified).

Where it applies: Contractor licensing above $50,000 (general contractor license threshold; pool work is not separately classified)

What applies instead: Structural, like Alaska: Delaware has no substantive pool/spa contractor license to reciprocate into. Contractors (including pool/spa work) register as a 'Construction Contractor' with the Division of Revenue and obtain a business license — there is no trade exam and no experience requirement for this registration. Out-of-state contractors register on the same terms as in-state ones, needing only a surety bond and the standard registration; no state license from another jurisdiction is 'accepted' or waived because there is nothing to waive.

There is no Idaho state licence for this trade to reciprocate. A contractor licence applies above $2,000.

What applies instead: Structural, like Alaska and Delaware: the Idaho Contractors Board is a registration body, not a licensing board - registration has no exam, no experience requirement, and no trade classification specific to pool/spa work. There is nothing for an out-of-state credential to waive; an incoming pool/spa contractor registers on the same terms (insurance, $50 fee) as a first-time applicant. Multiple sources confirm Idaho does not offer reciprocity for general/specialty contractor registration - distinct from its separate electrical/plumbing/HVAC licenses, which do have limited reciprocity with a short list of states.

There is no Illinois state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Illinois has no statewide general contractor or pool/spa contractor license. Pool construction businesses register at the municipal/county level (Chicago and other home-rule municipalities set their own requirements); the state licenses only specific adjacent trades (e.g., plumbers under 225 ILCS 320) whose work intersects with pool installation. There is no state license for an out-of-state pool credential to reciprocate into.

There is no Indiana state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Indiana has no statewide general contractor license; some municipalities (e.g., Mishawaka) separately license 'Swimming Pool Contractors' as a distinct local category, alongside general contractors, roofers, etc. Only plumbing is licensed statewide (Indiana Plumbing Commission/IPLA). Because pool/spa licensing is purely municipal and each city runs its own exam and bond requirements, there is no state authority that could grant reciprocity to an out-of-state credential, and municipalities generally do not recognize each other's licenses, let alone out-of-state ones.

There is no Iowa state licence for this trade to reciprocate. A contractor licence applies above $2,000/year in business.

What applies instead: Iowa requires construction contractors (including pool/spa builders) to register annually with DIAL under Chapter 91C - a registration, not a licensure scheme with an exam or trade-specific classification, so there is no substantive pool/spa standard for an out-of-state credential to reciprocate into. One asymmetry worth knowing about: DIAL's own guidance states that out-of-state contractors must additionally provide 'A bond as described in Iowa Code chapter 91C' as part of registration - a requirement not clearly imposed on in-state contractors - so out-of-state registrants may face a stricter bonding condition rather than a favorable reciprocity provision. This distinction could not be fully resolved from DIAL'S public pages and should be confirmed directly with the department.

There is no Kansas state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Kansas has no statewide contractor licensing of any kind for pool/spa or general construction work. Regulation is entirely local: Johnson County issues a Class 'DS' license specifically for pool/spa/hot-tub installation, service and repair, while other counties (Sedgwick) run their own separate class system. Kansas'S 105 counties each set independent rules that do not carry over to other counties, so there is no state-level mechanism to grant reciprocity to an out-of-state credential, and local jurisdictions generally do not recognize each other's licenses either.

There is no Kentucky state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Kentucky has no statewide general or pool/spa contractor license - only electrical, plumbing and HVAC contractors are licensed statewide through the Department of Housing, Buildings and Construction. Pool construction and general contracting are regulated purely at the municipal level (Lexington, Louisville, Bowling Green each maintain separate registration/licensing processes). There is no state authority to grant reciprocity for pool/spa work.

There is no Maine state licence for this trade to reciprocate. A contractor licence applies above $3,000 (written-contract requirement, not a licensing threshold).

Where it applies: Contractor licensing above $3,000 (written-contract requirement, not a licensing threshold)

What applies instead: Maine issues no statewide general contractor or pool/spa contractor license - the state licenses only electricians, plumbers and a handful of hazardous-materials trades through the Office of Professional and Occupational Regulation. Pool/spa construction is governed purely by local business licenses and municipal building codes (MUBEC). There is no state authority to grant reciprocity for pool/spa work; the written-contract requirement for projects over $3,000 is a consumer-protection rule, not a license.

There is no Minnesota state licence for this trade to reciprocate. A contractor licence applies above $15,000/year gross annual receipts (triggers Residential Building Contractor licensure only for multi-skill contractors).

Where it applies: Contractor licensing above $15,000/year gross annual receipts (triggers Residential Building Contractor licensure only for multi-skill contractors)

What applies instead: DLI states explicitly: 'Specialty contractors who provide only one special skill are not required to have a state license (except residential roofers).' A pool/spa/hot tub installer performing only that one specialty is regulated purely at the city level (a municipal license and Certificate of Insurance), with no state credential to reciprocate into. However, if a contractor bundles pool/spa work with other skills into a single contract with a homeowner - more than one special skill - the state Residential Building Contractor license IS required for that broader scope, and Minnesota 'does not have reciprocity agreements with other states for general contractor licensing,' so an out-of-state credential provides no waiver in that scenario either. This is the same 8-special-skills structure that governs the contractor-threshold trades in Minnesota.

There is no Missouri state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Missouri has no statewide general contractor or pool/spa license. St. Charles County, for example, separately licenses 'pool installers' as a distinct local trade category alongside electricians, plumbers and HVAC contractors, but this is purely a county-level credential with no state authority behind it and no basis for state-level reciprocity.

There is no Montana state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Montana does not require a statewide contractor license for pool construction; there is no state-level license specific to pool builders. All permitting and oversight falls to local building departments. Plumbing and electrical work performed as part of a pool build must be done by separately state-licensed plumbers/electricians, but this is incidental trade licensing, not a pool-specific credential, and provides no basis for reciprocity at the pool-contractor level.

There is no Nebraska state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Nebraska does not license general or pool/spa contractors at the state level. Regulation is purely local (city/county permitting and any local contractor registration). There is no state authority to grant reciprocity for this trade.

There is no New Hampshire state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: New Hampshire has no statewide general contractor or pool/spa contractor license, and no statewide home improvement contractor registration (unlike neighbouring Massachusetts). Pool/spa construction is governed purely by local building permits and any municipal licensing - Manchester, for example, requires a surety bond for local registration. There is no state authority to grant reciprocity for pool/spa work; New Hampshire's 2023 reciprocity law (HB 594) applies to OPLC-licensed trade boards, which do not include general or pool contracting.

There is no New York state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: New York has no statewide licence for pool/spa contractors; requirements are set locally, most prominently in NYC where only a Licensed General Contractor - which requires a NYC business location - can pull permits for pool installation, plus HIC licensure for 1-4 family homes. Because this is purely municipal there is no state authority to grant reciprocity, and NYC does not appear to recognise out-of-state or other-municipality contractor licences.

There is no North Dakota state licence for this trade to reciprocate. A contractor licence applies above $4,000.

What applies instead: Structural, like Alaska and Idaho: North Dakota's contractor licensing has no state examination requirement, no minimum experience requirement and no formal education requirement for any class - it is gated purely on business registration, liability insurance and, for employers, workers' compensation through the state's monopolistic WSI system. Pool/spa work is not a distinct classification; it falls under the general Class A-D licences based on contract size. Since there is no substantive standard to waive, an out-of-state contractor registers on the same terms as a first-time applicant.

There is no Ohio state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Ohio does not license pool/spa or general contractors at state level; only electrical, plumbing, HVAC and refrigeration contracting require a statewide OCILB licence, none of which is a pool-specific classification. Pool/spa construction is regulated purely by local building departments and any municipal contractor licensing. There is no state authority to grant reciprocity for this trade.

There is no Oklahoma state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Oklahoma's CIB does not issue a general building contractor licence, and pool/spa construction is not among CIB'S named specialty trades (electrical, plumbing, mechanical, roofing, alarm/locksmith). CIB's own FAQ confirms reciprocity exists only for CIB-licensed trades where 'Your state must have a written reciprocity agreement with Oklahoma' - but since pool/spa construction has no CIB licence category at all, that is moot here; regulation is purely municipal.

There is no Pennsylvania state licence for this trade to reciprocate. A contractor licence applies above $5,000 aggregate value in a 12-month period, triggering HICPA registration.

Where it applies: Contractor licensing above $5,000 aggregate value in a 12-month period, triggering HICPA registration

What applies instead: Pennsylvania has no statewide contractor licensing exam of any kind for general or pool/spa construction - HICPA requires only Registration (background check, $50 fee, proof of insurance) with no trade exam and no experience requirement. Since there is no substantive licensing standard to reciprocate into, an out-of-state pool contractor registers on the same terms as any first-time Pennsylvania contractor. Some municipalities layer additional local business licensing on top. Fee: $50 HICPA registration fee (biennial).

There is no Rhode Island state licence for this trade to reciprocate. A contractor licence applies above $500.

What applies instead: Rhode Island requires general Registration, not licensure with an exam, for anyone doing residential or commercial construction work including pool/spa contractors - the CRLB's own FAQ describes only insurance, business ID and fee requirements, with no trade examination for general contracting. Because there is no substantive licensing standard for pool/spa work specifically, an out-of-state contractor registers on the same terms as a first-time applicant. The CRLB separately licenses, with exams, only Home Inspectors, Well-Drilling Contractors, Pump Installers, Water-Filtration Contractors and Underground Utility/Commercial Roofing contractors - none of which covers pools.

There is no South Dakota state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: South Dakota does not test or grade general contractors of any kind, including pool/spa builders - the only statewide credential is a tax registration with no fee, no exam and no bond, existing purely to collect the 2% contractor's excise tax. Since there is no substantive competency standard, there is nothing for an out-of-state pool/spa credential to reciprocate into; contractors register identically regardless of out-of-state licensure. Actual contractor licensing, where it exists, is purely local.

There is no Vermont state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Vermont has no dedicated pool or spa licence, and no statewide general contractor licence either. Only electrical and plumbing work is separately state-licensed, through the Division of Fire Safety, and that is unrelated to pool and spa construction itself. What does apply at this scale is the Residential Contractor Registry, effective 1 April 2023, which requires registration for residential work of $10,000 or more on buildings of four or fewer dwelling units — that reaches residential pool construction. It changes nothing about reciprocity, though, because the Registry has no examination and no experience requirement for anyone, in-state or out. It is gated purely on insurance, at $1,000,000 and $2,000,000 liability minimums, and a written-contract mandate. There is no competency credential here for an out-of-state licence to substitute for.

There is no Washington state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Washington regulates pool/spa contracting through Registration, not an examined licence - L&I verifies a surety bond, liability insurance and a Unified Business Identifier for the 'swimming pools, spas and hot tubs' specialty category, with no trade exam or experience test. Because there is no substantive competency standard for this category, an out-of-state pool/spa contractor registers on the same terms as a first-time applicant; there is nothing to waive. Washington separately certifies individual electricians and plumbers with real exams, but that is a different, incidental trade.

There is no Wyoming state licence for this trade to reciprocate. Local rules may still apply.

What applies instead: Wyoming does not issue a statewide general contractor or pool/spa licence; contractor licensing and registration are handled entirely at local city/county level and requirements vary by jurisdiction. There is no state authority to grant reciprocity for this trade.
