Centennial Building Permit — Filed & Tracked For You

Centennial is one of Colorado’s youngest cities, incorporated in two thousand and one, and its building regulations are unusually explicit about what it has chosen not to adopt. The most consequential of those choices concerns what happens when you disagree with the building official.

The Building Division handles permits, plan review and inspections, with contractor licensing administered under a separate chapter of the municipal code carrying its own classes, insurance requirements and enforcement powers.

This guide covers work inside the Centennial city limits in Arapahoe County. Unincorporated Arapahoe County is permitted by the county, and Aurora and the neighbouring south metro cities permit separately.

What requires a building permit in Centennial?

Colorado has no statewide building code. Home rule leaves adoption to local government, so whether a building code applies at all, and which edition, is decided by the municipality or the county — roughly two hundred and seventy municipalities and sixty-four counties, each choosing for itself. That makes the edition in force in Centennial a local question, and an exempt list or fee schedule from a neighbouring jurisdiction unreliable. What it does not make Colorado is a state where nothing is decided centrally.

An exemption from a building permit is never an exemption from zoning, from the adopted energy provisions, or from a trade permit. Confirm scope with the Centennial Building Division before work starts.

Four things Colorado decides centrally, whatever the local code says

First, electrical and plumbing: the National Electrical Code and the Colorado plumbing code are state baselines, and the state boards permit and inspect wherever no local programme exists. Second, energy: under House Bill 22-1362 no jurisdiction is compelled to update its codes, but any jurisdiction that adopts or updates a building code must take up at least the specified minimum energy code, so the floor arrives with the update rather than on a statewide date. Third, the conflict rule: where the energy provisions or the state model codes conflict with the Colorado plumbing code or the National Electrical Code, the plumbing code or the electrical code prevails. Fourth, wildfire: the Colorado Wildfire Resiliency Code adopted in twenty twenty-five sets a state minimum for new construction and significant exterior alterations and additions inside the mapped wildland-urban interface, and it is not a retrofit code. Altitude derating, snow loading and expansive soils are live design constraints across much of the state. The city has also amended the appeals route out of existence: the building code section establishing a board of appeals is deleted in its entirety, so there is no local administrative body to which a decision of the building official can be appealed. Disputes are resolved with the official or not at all, which changes how a contested interpretation should be handled from the outset

Who handles permitting in Centennial?

The Building Division issues permits, reviews plans and inspects work under the city’s building regulations chapter, with contractor licensing and enforcement administered under a separate chapter carrying its own classes and insurance requirements.

Licence classes are named and scoped rather than generic. An asphalt paving licence entitles the holder to contract for and perform asphalt placement, patching, sealing and similar work in the public right of way and on private property. A concrete and form licence covers installing forms, and pouring, finishing and mixing concrete products. The class has to match the work rather than the trade in general.

The stop work power is broader than a defect notice. Where violations occur on a job site holding a valid building, fence, right-of-way, sign or engineering permit, the chief building official may issue a stop work order that remains in effect until the contractor has complied with all rules and regulations set forth in the chapter — not merely until the particular violation is corrected.

Permit types

Residential permits

New single-family work carries the site certification requirement for setback verification. The city has also amended several technical provisions: gas piping test pressure is raised from three to ten pounds per square inch gauge, and sewer depth is specified at twelve inches. Both are local departures from the model text.

How Colorado contractor credentials work

Colorado has no state general contractor licence. General contractor licensing is done by municipalities and counties, many of which also require a surety bond, so a credential earned in one Front Range city does not necessarily travel to the next. The trades are the opposite: electricians and plumbers are licensed by the state, through the State Electrical Board and the State Plumbing Board, and those licences are statewide. A journeyman electrician works under a registered electrical contractor and cannot independently pull permits.

Commercial permits

Commercial work runs through plan review with residential review typically running ten to fifteen business days and commercial fifteen to thirty depending on complexity. Flood hazard areas are established for the city by amendment with a defined issuance date, and stamped written reports from a Colorado licensed professional engineer are required for certain inspections.

Local licences, state trade registration and design professionals

Three credential layers appear on a Colorado project and they are held by three different bodies: the local general contractor licence and any bond the jurisdiction requires; state registration for the electrical and plumbing contractors, verified with the state boards; and, on commercial and larger residential work, drawings stamped by a Colorado-licensed architect or professional engineer. Confirm what the Centennial Building Division requires for the specific building before filing.

Centennial permit costs and fees

Centennial fees follow the published schedule by permit type and valuation. Insurance is a precondition rather than a fee: every licensed or registered contractor must maintain workers compensation and general liability at the published limits throughout.

Because Colorado sets no statewide building fee schedule, two jurisdictions on the same model code can price the same project very differently. The component most often missed is the trade permit, because on a job outside a local inspection programme it is paid to a state board rather than to the city. Ask the Centennial Building Division for the schedule in force on your filing date, and confirm the electrical and plumbing route separately.

Trade permits and who may pull them

Trade permits in Colorado are not necessarily issued by the same body as the building permit. Where the jurisdiction runs its own electrical or plumbing inspection programme, the trade permit is local. Where it does not, the permit and the inspection come from the state board instead, and state-issued permits run for one year from issue.

• Electrical work follows the National Electrical Code as adopted by the state and amended locally, performed by a state-licensed electrician working for a registered electrical contractor.
• Plumbing work follows the Colorado plumbing code, performed by a state-licensed plumber for a registered plumbing contractor.
• Mechanical and fuel gas work follows whichever mechanical provisions the jurisdiction adopted, permitted locally.

How to apply for a Centennial building permit

Review, corrections and what actually causes delay

The first cause of delay in Colorado is the trade split: a project waits on a city inspection that was never going to happen, because the electrical or plumbing permit sits with a state board. The second is the wildland-urban interface, where a parcel inside the mapped area brings requirements the building code alone does not describe. The third is the energy code, because the tier a jurisdiction sits on depends on when it last updated rather than on a statewide date. The fourth is edition drift between neighbouring jurisdictions on the same corridor. There is no statutory review clock for building permits: any timeline you are given is that jurisdiction’s own target. Confirm the checklist with the Centennial Building Division before filing.

Inspections in Centennial

Standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and energy compliance, fire systems on commercial work, and final, with a certificate of occupancy before the building is used. Certain inspections require a stamped written report of the results provided to the building official by a Colorado licensed professional engineer.

Plan around the possibility of two inspection queues. Where the state boards hold the electrical or plumbing permit, their inspectors attend on the state’s schedule and the local inspector will not sign off that trade. State board policy is that the contractor or a representative, or an adult homeowner or their representative, must be present for the inspection of an occupied dwelling unit — so an unattended property cannot be inspected.

Do not cover work before the required inspection has been approved. Keep the issued permits, the approved plans and the energy compliance documentation available on site.

Centennial permit search and official resources

Permit records in Colorado are split the way the permits are. Where the Centennial Building Division is the authority for the City of Centennial, it holds the building record — but an electrical or plumbing permit issued by a state board sits with that board instead. If you are buying, refinancing or renovating, check both, because a clean local record does not mean the trade work was ever permitted.

Frequently asked questions

Can I appeal a decision of the building official?

Not locally. The city has amended the building code section establishing a board of appeals by deleting it in its entirety, so there is no local administrative body to hear an appeal from the building official's decision.

What does a new house need that other cities may not require?

A site certification. The city requires one prepared by a State of Colorado registered design professional for setback verification on all new Group R Division 3 occupancies, which covers new single-family dwellings.

What insurance does my contractor need?

Workers compensation as required by state statute in the statutory amounts, and general liability with minimum limits of one million dollars per occurrence and two million dollars aggregate, evidenced by a certificate naming the city as holder before the licence or registration issues.

What happens if the city stops my job?

It can stay stopped longer than you expect. Where violations occur on a site holding a valid permit, the chief building official may issue a stop work order that remains in effect until the contractor has complied with all rules and regulations set forth in the chapter.

Which code edition applies?

The edition Centennial adopted, with its amendments. Colorado has no statewide building code. Home rule leaves adoption to local government, so whether a building code applies at all, and which edition, is decided by the municipality or the county — roughly two hundred and seventy municipalities and sixty-four counties, each choosing for itself. House Bill 22-1362 does not compel any jurisdiction to update, but when a jurisdiction adopts or updates a building code it must take up at least the specified minimum energy code, so the energy floor arrives with the update rather than on a statewide date. Where the energy provisions or the state model codes conflict with the Colorado plumbing code or the National Electrical Code, the plumbing code or the electrical code prevails.

Who licenses my electrician?

The state. The trades are the part Colorado does decide centrally. The State Electrical Board and the State Plumbing Board issue permits and carry out inspections everywhere in the state with no local inspection programme of its own, and the state does not inspect where a local programme exists, so establishing the correct authority for the job site is the applicant's responsibility. State-issued permits run one year from the date of issue. Electricians and plumbers are licensed by those state boards and the licences are statewide, while general contractors are licensed by municipalities and counties, often with a surety bond. It is a violation of state law for anyone other than the homeowner, who is not a registered electrical or plumbing contractor, to install that work.
