Illinois Pool Contractor License Requirements (2026)

Illinois issues no single statewide "pool contractor license." Instead, the state credential — the Illinois Department of Public Health (IDPH) "Prequalified Swimming Facility Contractor" status — applies ONLY to PUBLIC and commercial swimming facilities: pools, spas, bathing beaches, and aquatic features at apartment or condominium properties with five or more living units, hotels, clubs, schools, parks, health clubs, and similar establishments. Pools and spas at private single-family residences intended solely for the owner and guests are expressly excluded from the statutory definitions of "swimming pool," "spa," and "swimming facility" (210 ILCS 125; 77 Ill. Adm. Code 820.10) and require NO state credential — residential pool construction is governed only by local municipal or county building permits and codes. For public-facility work, IDPH prequalifies contractors through a points-based technical and work-history evaluation and issues per-project construction and major-alteration permits under the Swimming Facility Act.

Regulatory Body Profile

Authority over this credential rests with Illinois Department of Public Health, Division of Environmental Health (IDPH), which issues and polices it under Swimming Facility Act, 210 ILCS 125; Swimming Facility Code, 77 Ill. Adm. Code 820. IDPH prequalifies swimming facility contractors and architects/engineers and issues construction and major-alteration permits for PUBLIC swimming pools, spas, bathing beaches, and aquatic features. It does not regulate general contractors or private single-family residential pools; Illinois has no statewide general contractor license.

The Eligibility Audit

The applicant must be at least 0 years of age and possess a valid Social Security Number. No residency requirement is stated in the Act or Code. If the contractor is an LLC or corporation, it must be registered and in good standing with the Illinois Secretary of State (77 Ill. Adm. Code 820.530).

Good moral character

Background investigation

No criminal background check is required by the Swimming Facility Act or Code. Prequalification may be denied, suspended, or revoked under a demerit-point system for violations of the Act or Code (77 Ill. Adm. Code 820.540), but no fingerprint-based or criminal-history check is specified. Verify current requirements against the IDPH application form before filing.

Experience and Education Standards

The cited source set does not publish a fixed year-based experience threshold for this credential. The controlling requirement is No fixed number of years is required. Prequalification is granted on a 75-point evaluation of technical expertise and work history — the number of public swimming facilities built, altered, or renovated, and the number self-performed — plus mandatory completion of IDPH's annual swimming facility prequalification training. The contractor must self-perform a minimum of 25% of the permitted work and pool proper (77 Ill. Adm. Code 820.530)..

Accepted proof of experience or eligibility

Completed IDPH prequalification application for contractors detailing technical expertise and work history (facilities built, altered, renovated, and self-performed)
Illinois Secretary of State registration or certificate of good standing if the applicant is an LLC or corporation
Evidence of successful completion of IDPH swimming facility prequalification training

Education substitution

Not applicable for contractors. Education is a scored factor only for prequalified architects and engineers, who must additionally hold an active IDFPR design-professional license.

The Exam Syllabus

There is no statewide written trade test for this credential in the cited record; the controlling process is: No written state trade examination is required. In place of an exam, contractor prequalification requires successful completion of IDPH's annual swimming facility prequalification training plus a minimum score of 75 points on the point-based work-history and technical-expertise evaluation (77 Ill. Adm. Code 820.530, Appendix B). This applies only to public-facility construction; residential pool builders take no state exam.

Examination fee: none

Retake policy: If initial prequalification is denied, the applicant may reapply 30 days after the date of denial. The Department will not issue the same applicant more than two initial prequalifications consecutively or within a five-year period.

Bonding, Insurance & Financial Security

There is no statewide surety bond tied to this credential in the cited record. Bonding can still surface at the project level — permit, license, or public-works bonds — so check before you bid.

General liability

Not required by IDPH for prequalification. Local building departments may require liability insurance as a condition of pulling permits.

Workers' compensation

Not a prequalification requirement. Standard Illinois employer workers' compensation law applies to any contractor with employees but is not administered as part of this credential.

Additional financial requirements

Not required.

Schedule of Fees

Fee	Amount
Application (non-refundable)	No separate state fee
Initial license	No separate state fee

Renewal and Continuing Obligations

The Prequalified Swimming Facility Contractor (IDPH) — public swimming pools & spas only runs on a 2 years renewal cycle. No separate statewide renewal fee is listed in the cited sources. The renewal application must be submitted to IDPH 60 days before expiration. Initial prequalification is valid one year; renewals are valid two years. IDPH will not issue the same applicant more than two initial prequalifications consecutively or within a five-year period. Under the separate demerit-point system (77 Ill. Adm. Code 820.540), 40-74 accumulated points results in a 30-day suspension reinstated after retraining, and 75 or more points results in revocation with a one-year bar on reapplying.

Continuing education: Successful completion of IDPH's annual swimming facility prequalification training is required for renewal; renewal is granted or denied on the 75-point evaluation.

Out-of-State Reciprocity

For this classification, Illinois does not recognize the NASCLA Accredited Examination.

Reciprocal State	Accepted Exam	Conditions

The Application Roadmap

Determine whether the project is in scope. Confirm the facility is a PUBLIC or commercial pool, spa, bathing beach, or aquatic feature (e.g., 5-plus-unit residential property, hotel, club, school, park). Private single-family residential pools are excluded from state regulation and require only local permits.
Register the business entity. If the contractor is an LLC or corporation, register and remain in good standing with the Illinois Secretary of State, as required by 77 Ill. Adm. Code 820.530.
Complete IDPH prequalification training. Attend and successfully complete IDPH's annual swimming facility prequalification training, which is mandatory for both initial prequalification and renewal.
Submit the prequalification application and document work history. File the IDPH Swimming Facility Prequalification Application for Contractors, documenting technical expertise and the number of public facilities built, altered, renovated, and self-performed to reach the 75-point minimum score under Appendix B.
Obtain prequalified status and honor the self-perform rule. Once prequalified, the contractor must self-perform at least 25% of the permitted work and the pool proper on each project. Initial prequalification is valid one year from issuance.
Secure per-project IDPH construction/major-alteration permits. For each public project, the permit applicant (typically the facility owner) must obtain an IDPH construction or major-alteration permit and pay the surface-area-based fee, plus any local building permits, before construction begins.
Renew before expiration. Submit the renewal application to IDPH 60 days before expiration, complete the annual training, and pass the 75-point evaluation. Renewals are valid two years.

Where Applications Stall

The errors below are the ones that most frequently cost Illinois Pool Contractor applicants time, drawn from the cited board guidance.

Assuming a state pool-contractor license exists

Illinois has no statewide general contractor license and no contractor-board pool specialty. The only state pool credential is IDPH prequalification, and it applies solely to public/commercial facilities — do not expect a transferable state contractor license.

Treating residential and public pools the same

Private single-family residential pools are excluded from IDPH regulation and need only local permits, while public facilities require IDPH prequalification and per-project permits. Misclassifying scope leads to either unnecessary filings or an illegal public build.

Overlooking the 25% self-perform and training requirements

Prequalification is not a one-time formality: the contractor must self-perform at least 25% of the permitted work and pool proper and complete IDPH training every year to keep and renew the credential.

Confusing the free credential with per-project permit fees

The prequalification credential costs nothing, but IDPH construction/major-alteration permit fees ($625-$1,950 for new pools/spas; $310-$975 for major alterations) are paid per project by the owner. Budgeting for a 'license fee' misreads how Illinois charges.

Ignoring adjacent trade licensing

Pool plumbing must be performed by an Illinois-licensed plumber and electrical work is licensed locally. These separate requirements are not covered by IDPH prequalification and must be handled independently.

Common Questions

Do I need a state license to build a backyard pool in Illinois?

No. Pools and spas at private single-family residences intended only for the owner and guests are expressly excluded from the statutory definitions of "swimming pool," "spa," and "swimming facility" (210 ILCS 125; 77 Ill. Adm. Code 820.10). Residential pool construction has no state license and is governed only by local municipal or county building permits, barrier/safety codes, and any local contractor registration.

What is the IDPH "Prequalified Swimming Facility Contractor" credential?

It is Illinois' state-level credential for building or altering PUBLIC and commercial swimming facilities — pools, spas, bathing beaches, and aquatic features at properties such as 5-plus-unit residential buildings, hotels, clubs, schools, and parks. IDPH grants it through a points-based evaluation of technical expertise and work history rather than a licensing exam, and it applies only to public-facility work.

Is there a written exam or a licensing fee?

No. There is no written state trade examination and no credential fee — prequalification is free of charge under 77 Ill. Adm. Code 820.500. In place of an exam, the contractor must complete IDPH's annual prequalification training and score at least 75 points on the work-history and technical-expertise evaluation. Costs instead arise from per-project IDPH permit fees paid by the facility owner.

Is a surety bond or general liability insurance required?

IDPH does not require a surety bond, general liability insurance, or a financial statement for prequalification. However, local building departments may require liability insurance to pull permits, and standard Illinois workers' compensation law applies to any contractor with employees even though it is not administered as part of this credential.

How long is prequalification valid and how do I renew?

Initial prequalification is valid one year from issuance; renewals are valid two years. The renewal application must be submitted to IDPH 60 days before expiration, and the contractor must complete the annual training and again meet the 75-point evaluation. IDPH will not issue the same applicant more than two initial prequalifications consecutively or within a five-year period.
