Coverage
Colorado plumbing and gas code by city
Colorado uses the International Plumbing Code (IPC) and International Fuel Gas Code (IFGC), not the UPC. The state’s code is based on the 2024 IPC and IFGC, but most Front Range cities and counties adopt their own edition with local amendments. The table below shows the adopted edition and effective date for 136 jurisdictions.
Does Colorado use the IPC or the UPC?
The IPC and IFGC. The state’s minimum code, the Colorado Plumbing Code (3 CCR 720-1), is built from the 2024 IPC and the plumbing chapters of the 2024 IRC with Colorado changes. The Colorado Fuel Gas Code is based on the 2024 IFGC. Both took effect Aug 14, 2026.
Is there one statewide plumbing code?
The state code is the minimum everywhere. Cities and counties that run their own permits and inspections adopt their own edition and add local amendments, and they can be stricter than the state but not weaker. Where no local department issues plumbing permits, state plumbing inspectors do the inspections.
How many jurisdictions are on each edition?
Of the 136 jurisdictions below: 49 on the 2024 IPC, 38 on 2021, 13 on 2018, 4 on an older edition, and 32 where the city follows the state code or its edition isn’t listed yet. See which cities changed editions recently in the 2024 code guide.
Why does the edition matter on a job?
The same section can say different things in different editions. Then local amendments change values on top of that. Sewer depth, for example, is a blank the city fills in. See sewer depth by city and gas test pressure by city.
What’s not in this table?
The local amendments: the app has 1,746 plumbing and fuel gas amendments for the cities and counties it covers.
