Colorado pool regulation snapshot
CDPHE's Swimming Pools and Mineral Baths regulation (5 CCR 1003-5, effective Dec 15, 2020) sets statewide standards for public and semi-public pools. It lets local agencies adopt the CDC Model Aquatic Health Code (MAHC) instead; Summit County, for example, adopted MAHC 5th ed. in Feb 2026. Pools serving only residents of single-family homes, condos or apartments are exempt under the state rule. Colorado has no statewide residential building code and no statewide general-contractor license; the state licenses electricians (2023 NEC) and plumbers.
Health and operating oversight
Regulator: CDPHE, Division of Environmental Health & Sustainability (Institutions and Emerging Programs), together with county and district public health agencies, which do most plan review, licensing and inspection.
Building-code path
Building code: Local adoption only. Counties and cities adopt the IRC/ISPSC, e.g. Denver's Building Code includes an ISPSC appendix (edition not verified). The state adopts the 2023 NEC, effective Aug 1, 2023 (State Electrical Board), and a statewide plumbing code (edition not verified).
State-level starting point
State barrier law: None found.
VERIFIED STATE RESEARCH CONTEXT
Colorado local-contractor and trade research
Colorado general-contractor licensing is commonly administered by cities and counties, while the state regulates specified trades. Verify both the project jurisdiction's contractor rules and each state-regulated trade involved.
Checks to add to the project file
- Ask the city or county building authority which contractor license or registration is required for the address.
- Use Colorado DORA to verify state-regulated electrical, plumbing, and other applicable credentials.
- Put permit ownership, inspections, lien waivers, trade responsibility, and final approvals in the written scope.

What site conditions should a proposal for Longmont, CO address?
The proposal should respond to the actual survey, access, utilities, easements, grade, drainage, soil or groundwater information, neighboring property, barriers, and restoration needs. Use the Longmont, CO planning priorities above as interview prompts.
What should a pool construction proposal include?
