Permitting and Entitlements in Fort Collins and Larimer and Weld Counties
Permits submitted on or after April 1, 2026 in Fort Collins fall under the 2024 International Building Code with local amendments, and the 2021 codes remain available for reference until October 1, 2026. That kind of transition is common in Colorado, and it is why we treat permitting as a project phase that needs a plan, not a form to submit. The date a set of drawings is submitted can decide which code applies, which energy requirements govern and how much redesign is needed if the schedule slips.
We help owners and design teams approach entitlements and permits with clear sequencing. We meet the jurisdiction early, review the application requirements, flag the long-pole approvals and track the review comments until the permit is issued. The goal is a permit set that survives review without a second round of significant changes.
Codes Are Local in Colorado
Commercial building codes in Colorado are adopted city by city and county by county, not as one statewide code. A tracker from the Home Builders Association of Metro Denver dated January 20, 2026 shows some jurisdictions on the 2018 I-codes, others on 2021 and others on 2024. Unincorporated Weld County adopted the 2024 International Building Code effective June 15, 2026.
Energy requirements add another layer. Colorado HB22-1362 requires any county or municipality that updates a building code on or after July 1, 2023 to adopt an energy code with equivalent or better performance than the 2021 IECC and the state model electric and solar ready code, and from July 1, 2026 the benchmark becomes the state model low energy and carbon code. For a multi-jurisdiction owner, the lesson is to confirm the governing code for each site separately.
Design Review in a Place That Cares How Things Look
The Old Town historic area carries a layer of design standards on top of the building code. A city-designated Old Town Historic District dating to 1972 overlaps the National Register district and imposes design standards, and an overlapping River District extends north and east to the Cache la Poudre River.
Projects inside those areas can expect design review, which may include materials, massing, signage and storefront details. That review is separate from building plan review, so the two schedules should run in parallel. We encourage owners to engage with the review staff early and to present the design with enough detail to answer questions about materials and context.
Building a Permit Strategy Before the Drawings Are Done
Our first step is to identify every approval the project will need: zoning or site plan review, building permit, fire, utility connections, access permits from road authorities, stormwater and any special districts. We then place each on the schedule with an honest estimate of review time and an assumption about how many rounds of comments are typical.
Where possible, we split the work into separate permits to start earlier. A grading or foundation permit can sometimes be released before the full building permit, though it carries risk if the design changes. We discuss that tradeoff with the owner and the design team and document the decision. Owners who work with us through preconstruction estimating often see budget and permit questions answered together.
Review Times, Resubmittals and the Cost of Waiting
Plan review takes time, and the time varies with the jurisdiction, the project's complexity and the quality of the submission. Incomplete drawings, missing calculations and conflicts between disciplines lead to comment letters, which lead to resubmittals. A submission that is organized and coordinated tends to return fewer comments.
We help review drawing sets for coordination before they go to the city, and we track comments in a log that lists the response and the responsible party. For owners using design and build delivery, this process can overlap design and construction, which tightens the schedule but requires disciplined communication among all parties.
Permits Touch Every Other Service We Provide
Permitting is not a standalone activity. It affects long-lead procurement, since equipment orders may depend on approved submittals, and it affects the construction sequence, since inspections are hold points. It also determines when the building can be occupied, a date that the certificate of occupancy sets.
Public owners and developers have different pressures. A public agency may need to follow procurement and public-hearing steps that add months to the process, while a multifamily developer with a lender waiting needs predictable review milestones. Understanding which constraint matters most to you helps us structure the plan.
Documents That Help a Review Go Smoothly
A permit package is easier to review when it tells a consistent story. That means a code analysis that names the governing edition, structural criteria that match the local design values, and an energy compliance path that the reviewer can follow. In Fort Collins the design criteria include a 30 inch frost depth and a minimum ground snow load of 50 psf (ultimate) for Risk Category 1 and 2 buildings, and drawings that cite those numbers correctly avoid a comment.
Closeout paperwork belongs in this conversation too. The city provides a commissioning fact sheet and checklist alongside its 2024 code set, and commercial projects must pass air leakage testing. If the team knows about these requirements at submission, the inspection sequence at the end of the job is far more predictable. We keep a checklist of those closeout items from the first coordination meeting and carry it through our commissioning and closeout process.

Questions Owners Ask
Which code applies if my permit is submitted next month?
In Fort Collins, permits submitted on or after April 1, 2026 are reviewed under the 2024 International Building Code with local amendments. Other jurisdictions have their own dates and editions. Confirm the date with the building department, and have the design team document the code basis on the drawings.
Do we need a separate energy code review?
Colorado law pushes local governments that update their building code to adopt energy provisions at least as stringent as the 2021 IECC, and the benchmark rises from July 1, 2026. Fort Collins also requires commercial air leakage testing and provides a commissioning checklist. Your design team should address energy compliance in the submission.
How do design standards in Old Town change the schedule?
Projects in the historic district go through design review in addition to plan review. That adds time, and the outcome can influence materials and façade details. We recommend a pre-application conversation to learn what the reviewers will want to see.
Can construction begin before every approval is in hand?
Sometimes. Early grading, foundation or demolition permits can be issued separately, which saves time, but the owner takes on the risk that later review comments may change the design. We help you weigh that choice.
What does a contractor add to the permitting process?
We bring a builder's view of constructability, sequence and cost, which can prevent comments about means and methods. We also coordinate subcontractor permits and keep track of inspections. The owner and the design team still lead the application.
