Gilpin County Plumbing Permit Requirements
Effective March 1st, 2023, Gilpin County is responsible for issuing all electrical and plumbing permits in unincorporated areas of the county. If you have an active permit issued by the State of Colorado, you will need to continue and complete that permit with the State. All electricians and plumbers performing work in Gilpin County must register with the county by submitting a Contractor Registration application before commencing any work on building, electrical, or plumbing permits. If you are a contractor working under a permit where you are not the applicant, you must contact Gilpin County Community Development at [email protected] or 303-582-5831 to have your registration number associated with the permit. You will need to provide the permit number or project address in your request.
Gilpin County has adopted the 2018 International Plumbing Code (IPC), along with local amendments. Plumbing installations must comply with the IPC and any applicable local amendments. Homeowners may perform their own plumbing work if they are performing the work themselves, the property is not for sale, resale, or rent, and is not generally open to the public. In such cases, all work must be inspected prior to covering and again upon completion. All plumbing work must comply with the adopted plumbing code.
For work done by a company, a licensed Plumbing Contractor is required to obtain the permits. Work cannot be done under a "homeowner" issued permit or a permit issued to another company. When applying for a plumbing permit, you will need to provide the valuation of the installation, which includes the cost of labor, materials, and items for commercial installations. For residential installations, a fixture count is required.
Permits are valid for one year from the date of issuance. Inspections must be requested online through the permit application portal by 5 PM the day prior to the desired inspection. Inspections are conducted on Mondays and Wednesdays only.
Rules for Properties in Unincorporated Areas
In unincorporated Gilpin County, all electrical and plumbing permits are issued by the county. This includes properties in these areas. Most land in unincorporated Gilpin County is zoned as either Resource Residential (RR) or Residential Subdivision (RS). These zones generally permit only one single-family home and one accessory dwelling unit per parcel. Higher-density residential uses like duplexes or triplexes are not permitted in these zones.
When constructing a single-family home, there are no minimum or maximum size restrictions, provided that the total land coverage of all structures on a parcel does not exceed 25%. Accessory dwelling units (ADUs) can be attached or detached and cannot exceed 50% of the primary dwelling's floor area. Setback requirements for RR zones are 30 feet from the front property line, 15 feet from other sides, and 55 feet from the centerline of unplatted/undedicated roadways. For RS zones, setbacks are 30 feet from all property lines or 55 feet from the centerline of unplatted/undedicated roadways.

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.
