Commerce City Building Permits & Inspections: What to Do First
If your project is inside Commerce City, Colorado, building permits, plan reviews and most construction inspections are handled by the city’s Building Safety Division, part of Community Development. Most of the process is online through eTRAKiT, so you usually do not need to visit an office just to submit an application, pay a fee or request an inspection.
The part that causes people the most trouble is not filling out the form—it is choosing the right jurisdiction, permit type and supporting documents before submitting. This guide walks through those decisions first so you can avoid a preventable rejection or delay.

First: Make Sure Commerce City Is Your Permit Authority
A Commerce City mailing address does not always prove that the property is inside Commerce City limits. The city’s own eTRAKiT guidance warns that some addresses may actually be in unincorporated Adams County, Brighton, Denver or another jurisdiction.
Before preparing plans:
- Search the exact property address in Commerce City’s property or eTRAKiT system.
- Confirm the address appears as a Commerce City property.
- If it does not appear, check your deed, closing paperwork or county property information.
- Do not submit a city permit merely because the mailing address says Commerce City.
If your property is outside the incorporated city and falls in an unincorporated area, see our Adams County, Colorado building permit guide. A nearby property inside Aurora follows a completely different system, explained in our Aurora building department guide.
Do You Need a Building Permit?
Commerce City requires permits for most new construction, structural alterations and regulated mechanical, plumbing, electrical or demolition work. A project that does not need a building permit can still be subject to zoning, setback, HOA, utility or other code requirements.
| Project | Commerce City guidance |
|---|---|
| New building or addition | Permit required |
| Finished basement / interior alteration | Permit required |
| Deck or porch | Permit required |
| New or replacement HVAC equipment | Permit required |
| Gas appliance or gas-system work | Permit required |
| New plumbing fixtures | Permit required |
| Hardwired EV charger | Permit required |
| Demolition | Permit required |
| Commercial or multifamily reroof | Permit required |
| Residential reroof | Building permit generally not required under the city’s published exemption list |
| Residential fence 72 inches or lower | Building-permit exempt, except pool barriers; zoning rules can still apply |
| Commercial fence 42 inches or lower | Building-permit exempt; other requirements can still apply |
| Residential same-size window/door replacement with no structural change | Building-permit exempt |
| Kitchen cabinets, flooring or cosmetic residential repair | Generally building-permit exempt |
| Retaining wall 4 feet or lower with no surcharge | Generally building-permit exempt |
| Retaining wall over 4 feet | Permit required |
The city’s list is guidance rather than an exhaustive list. If your project is unusual, call Building Safety at 303-289-3790 before purchasing materials or starting work.

Choose the Correct Permit Type
eTRAKiT separates construction permits into residential, commercial and other categories. One important detail is easy to miss: apartments and condominiums are treated as commercial projects, including alterations to an individual condo unit.
| eTRAKiT type | Common examples |
|---|---|
| RNEW | New detached homes, duplexes, mobile homes and eligible master-model construction |
| RADD | Additions, decks, garages, patio covers, sunrooms and similar residential additions |
| RALT | Basement finishes, interior remodels, foundation repair, fireplaces, egress work and residential alterations |
| RACC | Accessory structures such as certain fences, sheds, pools, hot tubs, gazebos and pergolas |
| RELEC | Residential electrical-only projects, including solar, service changes and EV chargers |
| RPLMB | Residential plumbing/gas work such as water heaters, piping and certain sewer repairs |
| RMECH | Residential furnaces, air conditioners, gas appliances and mechanical-only work |
| CNEW | New commercial buildings, apartment buildings, condominiums, mixed-use buildings and core-and-shell projects |
| CALT | Tenant improvements, commercial remodels, condo remodels, reroofs and changes of occupancy |
| CADD | Additions to existing commercial buildings |
| CO | Certificate of Occupancy, Temporary CO, Certificate of Completion or Temporary Certificate of Completion |
If you accidentally select the wrong permit type, the city says staff can transfer the application to the appropriate permit record and transfer applicable fees. Still, choosing correctly at the beginning reduces unnecessary handling.

How to Apply for a Commerce City Building Permit Online
Commerce City no longer accepts normal building permit applications as paper applications or ordinary emailed submissions. The process is electronic through eTRAKiT.
- Confirm that a permit is required. Check the city’s permit-required list and verify that the property is actually within Commerce City’s jurisdiction.
- Prepare the project documents. Depending on the work, this can include building plans, a site or plot plan, soils report, structural information, special-inspection statement, calculations, product evaluation reports or certification forms.
- Open the official eTRAKiT page. Start from the city’s eTRAKiT information page, then open the customer portal.
- Create the correct account. Property owners and general applicants can create a public account. Existing licensed contractors should use the contractor account connected with their city license.
- Select “Apply” under Permits. Choose the permit type that matches your project and complete the property, owner, contractor, valuation and work-description fields.
- Upload every required attachment. Missing plans or supporting files can stop the application during the city’s Gateway completeness review.
- Pay any required upfront fee. Certain applications will not move to staff review until the initial payment shown in eTRAKiT is completed.
- Watch your email and eTRAKiT account. If reviewers identify corrections, respond to every comment and upload the required revised documents.
- Pay the final balance. After approvals, the city performs pre-issuance review, verifies contractor licensing and adds remaining fees.
- Download the issued permit and approved plans. The city says the permit becomes available for download after issuance. Print the permit and applicable approved plans and keep them at the jobsite.
Prepare Electronic Plans Correctly
Incomplete or poorly prepared plans are one of the easiest ways to slow down an application. Commerce City prefers building plans in PDF format and publishes specific ePlan instructions.
- Combine architectural, structural and other building-plan sheets into one plan file when required.
- Do not lock the PDF or make it read-only.
- Use the correct plan scale.
- Include required professional seals and electronic signatures when the project requires a Colorado-licensed design professional.
- Upload reports, calculations and other supporting items with clear descriptions.
- For a correction cycle before permit issuance, the city generally asks for a full revised drawing set rather than isolated changed sheets.
- After permit issuance, revisions to approved plans must go back through the city’s revision process before the changed work is treated as approved.

What Your eTRAKiT Permit Status Means
| Status | What it generally means |
|---|---|
| Intake | The application has been submitted and entered into the system. |
| Under Review | Staff or applicable reviewing departments are reviewing the submission. |
| Approved | Required reviews have been approved, but the permit may not yet be issued. |
| Awaiting Payment | Outstanding fees have been added and must be paid. |
| Issued | The permit has been issued and the approved permit documents can be obtained through eTRAKiT. |
Commerce City Building Permit Fees in 2026
Building permit fees are primarily based on the complete project valuation. Commerce City defines valuation broadly enough to include the value of applicable labor, materials and regulated construction work—not merely the cost of the permit applicant’s materials.
The city’s May 2026 fee directory lists the following graduated building permit schedule:
| Total project valuation | Published building permit calculation |
|---|---|
| $1-$500 | $30.41 |
| $501-$2,000 | $30.41 for the first $500, plus $3.95 for each additional $100 or fraction |
| $2,001-$25,000 | $89.60 for the first $2,000, plus $18.11 for each additional $1,000 or fraction |
| $25,001-$50,000 | $506.24 for the first $25,000, plus $13.07 for each additional $1,000 or fraction |
| $50,001-$100,000 | $832.94 for the first $50,000, plus $9.06 for each additional $1,000 or fraction |
| $100,001-$500,000 | $1,285.10 for the first $100,000, plus $7.25 for each additional $1,000 or fraction |
| $500,001-$1,000,000 | $4,184.13 for the first $500,000, plus $6.15 for each additional $1,000 or fraction |
| Over $1,000,000 | $7,257.12 for the first $1,000,000, plus $4.72 for each additional $1,000 or fraction |
The same published schedule lists a standard plan-review charge of 65% of the building permit fee. Additional charges can apply for repeated reviews, reinspections, after-hours work, temporary occupancy or other project-specific services.
Do Not Forget Construction Use Tax
Permit cost and construction tax are not the same thing. Commerce City lists a 4.50% municipal use-tax rate for 2026. Its construction tax guidance explains that the city commonly estimates taxable construction materials at 60% of total construction cost when calculating the city’s estimated prepaid construction use-tax deposit.
Other state or district taxes can also exist, so do not estimate the entire project budget by looking only at the building permit fee.
Check current charges before payment: Building Permit Fees ↗ and Commerce City Sales & Use Tax ↗.
How Long Can Plan Review Take?
There is no single guaranteed turnaround for every building permit. Review time depends on the project type, completeness of the drawings, correction cycles and whether Planning, Public Works, fire, water, health or another agency must sign off.
Commerce City currently describes a general Community Development 3-2-1 review goal: approximately three weeks for a first review, two weeks for a second review and one week for later reviews. The city has also announced 2026 process improvements under which many Building Safety permits operate on a faster “2-1” review approach.
Treat those figures as review goals rather than a promised permit-issuance date. A missing document, contractor-license problem or outside-agency approval can extend the overall process.
Contractor Licensing Requirements
Contractors should make sure their Commerce City authorization is active before the permit reaches issuance. The city checks contractor licensing during pre-issuance review.
| License | Published fee | Typical scope |
|---|---|---|
| Class A | $120 | General building contractor; no listed construction limitation |
| Class B | $81 | Structures up to three stories |
| Class C | $60 | New construction and improvements to one- and two-family dwellings |
| Mechanical | $57 | Residential/commercial mechanical work |
| Electrical | $0 city fee listed | Requires applicable Colorado state and master licensing |
| Plumbing | $0 city fee listed | Requires applicable Colorado state and master licensing |
| Roofing | $57 | Residential/commercial roofing work |
| Specialty | $57 | Other qualifying specialty construction work |
Commerce City’s published licensing information also requires general liability insurance of at least $300,000, with Commerce City shown as the certificate holder. Testing or reciprocal-license evidence applies to several contractor classifications.
Homeowners may perform certain work on their own property without holding a contractor license, but that does not remove permit or inspection requirements for regulated work.
How to Schedule a Commerce City Building Inspection
Once your permit is issued and construction reaches an inspection point, schedule the required inspection through eTRAKiT. The city says eTRAKiT is the method for scheduling, changing and canceling building inspections.
- Log in to the eTRAKiT account connected with the permit.
- Locate the issued permit from your dashboard.
- Open the inspection scheduling option.
- Select the correct inspection type and desired available date.
- Submit the request before 4:00 p.m. on the business day before the desired building inspection.
- Confirm that the requested inspection appears in your active/scheduled inspections.
- Leave all work that must be inspected visible and accessible.
- Check eTRAKiT or the email connected with the permit for the inspection result and any correction information.
- Keep city-approved site plans, building plans and applicable shop drawings available.
- Provide safe access to the work.
- If yard access is required, follow the city’s instructions for entry permission and keep pets away from the inspection area.
- Provide ladders, scaffolding or other access equipment when necessary.
- Do not cover regulated framing, electrical, plumbing, mechanical or structural work before the required inspection.
- For solar work, electrical equipment must be open when required for inspection.
Same-day building inspections should not be expected. The city’s published cutoff is 4:00 p.m. the preceding business day.

Current Commerce City Building Codes for 2026
Commerce City is using the 2021 Commerce City Building Code together with the 2023 National Electrical Code. Local amendments matter, so a national code book by itself is not always enough to determine the local requirement.
| Code | Edition used by Commerce City |
|---|---|
| International Building Code | 2021 |
| International Residential Code | 2021 |
| International Existing Building Code | 2021 |
| International Mechanical Code | 2021 |
| International Plumbing Code | 2021 |
| International Fuel Gas Code | 2021 |
| International Energy Conservation Code | 2021 |
| International Swimming Pool and Spa Code | 2021 |
| International Green Construction Code | 2021 |
| National Electrical Code / NFPA 70 | 2023 |
The city also changed its residential sprinkler provisions in late 2025. Fire sprinklers are optional for new single-unit homes, duplexes and townhomes under the city’s amendment, although builders must offer the system as an option to buyers at the buyer’s expense.

Final Inspection and Certificate of Occupancy
A successful final building inspection does not always mean a new building or commercial tenant space can immediately be occupied. When a Certificate of Occupancy is required, it must be issued before occupancy.
Commerce City handles CO requests as a separate Certificate of Occupancy/Completion permit in eTRAKiT that is linked to the main construction permit.
Before requesting the certificate:
- Complete required city inspections.
- Make sure applicable outside-agency approvals are complete.
- Resolve outstanding permit or inspection corrections.
- Prepare required close-out documents.
- Apply for the CO/Completion permit in eTRAKiT.
Residential close-out documents can include an Improvement Location Certificate, Energy Compliance Certificate, Grading Certificate, applicable engineering inspection certification and UFER documentation.
A Temporary Certificate of Occupancy may be available when a portion of a project is safe for occupancy before all permitted work is complete. Eligibility is project-specific.
Official Certificate of Occupancy Instructions ↗
Building Safety Permit or Public Works Permit?
Not every construction-related permit is issued by Building Safety. Work affecting streets, sidewalks, public rights-of-way, grading or public infrastructure may need a Public Works permit instead of—or in addition to—a building permit.
| Building Safety | Public Works |
|---|---|
| Homes and commercial buildings | Right-of-way work |
| Additions and remodels | Street occupancy |
| Electrical, plumbing and mechanical work | Grading |
| Structural work | Public-infrastructure work |
| Building inspections | Applicable Public Works inspections |
For Public Works permitting, call 303-289-8150 or review the city’s Public Works Inspections and Permitting page ↗.
How to Search Existing Commerce City Permits
eTRAKiT can also be used to search permit records, contractor licenses, properties and certain inspection information.
- Open the Commerce City eTRAKiT portal.
- Select Search under the Permits section.
- Search with the permit number or another available property field.
- Open the matching permit to review the public information available.
If you know the permit number, enter it exactly as issued. The city also provides an “Issued Permits Report” option for issued permit records. Certain permit, licensing and payment information available through eTRAKiT does not require a separate Colorado Open Records Act request.

Common Problems That Delay a Permit
- Wrong jurisdiction: the address is actually in unincorporated Adams County or another city.
- Wrong permit category: especially treating a condo alteration as residential rather than commercial.
- Missing site plan or construction drawings: the application can stop at Gateway Review.
- Locked or incomplete plan PDFs: electronic documents must be usable by reviewers.
- Ignoring zoning: a building-permit exemption does not automatically waive setbacks or land-use standards.
- Expired contractor credentials: the city verifies contractor licensing before issuance.
- Starting before issuance: an application or approval status is not the same as an issued permit.
- Covering work before inspection: regulated construction must remain accessible until approved.
- Forgetting outside agencies: commercial and development projects can require fire, water, health, Planning or Public Works review.
If Your Property Is in Another Colorado Jurisdiction
Building rules can change sharply across city and county boundaries. For example, nearby jurisdictions use different portals, adopted codes and inspection procedures. If the property is not in Commerce City, use the correct local guide rather than applying Commerce City rules to the project.

- Aurora, Colorado Building Department — permits and inspections
