Denver, Colorado Plumbing Local Permit Ordinances and Codes
Denver Plumbing Permit Ordinances
In Denver, Colorado, plumbing work is regulated by the City and County of Denver, primarily through its Community Planning and Development (CPD) department, which handles plan review, permitting, and inspections. The city adopts and enforces the International Plumbing Code (IPC) with local amendments.
A plumbing permit is generally required for any modification or installation of pipes, including adding fixtures, rerouting plumbing, or replacing water heaters. However, replacing a fixture in-kind is typically exempt. Homeowners may be able to perform work on their primary residence as an owner-builder, provided they meet all code requirements and pass inspections.
Permit Fees and Nuances
- Permit fees for plumbing work in Denver typically range from $50 to $400, often based on the estimated project value. Some sources indicate fees as low as $20 for projects valued up to $500, with a sliding scale for larger projects.
- For commercial projects, permit fees are calculated as a percentage of the project's total valuation, with rates that decrease as the project value increases. Additional fees for plan review, system development charges, and impact fees may also apply.
- A "quick permit" system is available for certain smaller projects, which can expedite the process by bypassing a full plan review.
- Permits are generally valid for one year from the issue date. Extensions may be possible under certain conditions.
- Denver also has specific amendments to the International Plumbing Code, such as those regarding hydromechanical grease interceptors and sewage ejectors.

State-Level Plumbing Codes in Colorado
The State of Colorado establishes minimum standards for plumbing installations through the Colorado Plumbing Code. This code is primarily based on the 2021 editions of the International Plumbing Code (IPC), the International Fuel Gas Code (IFGC), and the plumbing provisions of the International Residential Code (IRC). The state adopts these model codes with specific state-level additions, revisions, and deletions, which are codified in the Code of Colorado Regulations (3 CCR 720-1).
Regulatory Authority
The primary agency responsible for setting and enforcing these standards is the Colorado State Plumbing Board, which operates under the Department of Regulatory Agencies (DORA). The Board is responsible for licensing plumbers, registering apprentices and contractors, issuing permits for state-inspected areas, and conducting inspections to ensure compliance with the state-adopted codes. While the state sets these minimum standards, local jurisdictions may also adopt and enforce their own building codes, which can sometimes be more stringent than the state requirements.
