Building Permits

A residential development under construction

Overview

This webpage combines all building permit information in one place — whether a permit is required, how to apply and what the process looks like from start to finish. 

This webpage provides general information to help you understand the City’s building code and legal requirements relating to permitting. It is not a substitute for legal advice or the law. You are responsible for following all applicable laws and regulations under Fort Collins City Code.

Do I Need a Building Permit?

Most construction projects require a permit. Some projects are exempt. See Permit Exemptions below.

Permit exempt does not mean code exempt. Even if you don’t need a permit, your project must follow City codes, laws and ordinances.

Stock Plans and Lot-Specific Permits

Some builders use standard home designs that can be approved once and reused on multiple lots. Others apply for a building permit for a specific lot.

Stock Plans

Notice: All active stock plans will expire the day new codes are adopted. Once a stock plan has expired, building permits can no longer be applied for using that stock plan. Building codes will be updated in December 2025. See Building Code for details. 

A Stock Plan is a set of standard building plans used for multiple buildings that share the same design. A Stock Plan is not a building permit, and doesn't allow you to build.

Once the City reviews and approves a stock plan, it can be reused on other lots without submitting the full plan again.

  • The plan review happens once for each model or design.
  • Each reuse still requires a Lot-Specific Permit, but the process is faster because the main plan is already approved.
  • Stock plans must be reviewed and stamped by the City before they can be used for permits.
  • Any design changes (layout, structure, materials, etc.) require a new plan review.
  • Stock plans expire the day new codes are adopted and a new stock plan will need to be applied for with all new documents to reflect the new codes. Submittals for new lot specific permits will not be able to use expired stock plans.
Here's how to apply for a Stock Plan based on your building type:

Lot-Specific Permits

A Lot-Specific Permit is the building permit for constructing a home on a particular lot. It uses an approved Stock Plan as its base but adds site-specific details such as foundation, grading and address.

  • Each home built from a stock plan must have its own lot-specific permit.
  • Site details (such as foundation or utilities) must match the approved plans.
  • Separate permits are required for each structure, each townhome unit (individual parcel) and solar installations.
  • Include the site-specific information, stock plan number and selected stock plan options in your permit submittal.
Here's how to apply for a Lot-Specific Permit:
What to submit:

Application:

Site Plan:

  • Lot specific site plan drawn to scale, showing the building with distance to property lines and adjacent structures on the same lot (if any) and setbacks.
  • For Single family houses, two family (duplex) and single family attached (townhomes) also include the outdoor area calculation.
  • Send as a single PDF with this naming convention: Site Plan - 1234 Example St - v1.

Lot-Specific Foundation Plan:

  • Lot specific footing and foundation design stamped and signed by a Colorado Licensed Structural Engineer. Framing Plans do not need to be included.
  •  NOTE: Even though preliminary foundation plans are reviewed with stock plan design, soils types and water table vary across Fort Collins, and within developments, which is why site-specific foundation design is required.
  •  Combine documents into a single PDF with this naming convention: FF Plans - 1234 Example St - v1.

How to Submit: Email to buildingservices@fortcollins.gov.

Other Permits

Temporary Use Permit

A Temporary Use Permit allows an existing building to be used as a temporary community-based shelter. You must also receive a Temporary Certificate of Occupancy (TCO) before the temporary use begins.

A Temporary Use Permit only covers the use of a building, not construction. Any plumbing, electrical, framing or other building work requires separate permits.

Who Can Apply

Permit Limits

  • A permit is valid for up to 180 days.
  • You can request an extension in writing from the Chief Building Official, but continuous operation beyond 180 days in a year is not allowed.
  • You may reapply for a new permit each year.
Occupancy and Facility Requirements

Maximum Occupancy:

  • Up to 15 guests (not including staff).

Cooking and Food Service:

Step 4: Permit Issued

Download your approved plans and keep them at your work site for construction and inspections.

Step 5: Construction and Inspections

Step 6: Corrections and Revisions

A revision is any change requested after your plans were reviewed or your permit was issued.

  • Examples: Layout changes, window type changes, on-site discoveries that require plan updates.
  • Department-initiated resubmittals (e.g., "Resubmittal Requested") follow a different process.

Why Submit a Revision?

  • Keeps official records accurate and prevents "work without a permit" issues.
  • Ensures changes meet building codes — even small changes can affect structure, occupancy or safety systems.
  • May change fees, required contractor licenses or trigger additional department reviews.

How to Submit a Revision

  1. Download your current approved set.
  2. Only revise the documents that changed. Keep the City's markups/comments — do not flatten them.
  3. When updating drawings:
    • Replace/add/delete sheets as needed.
    • New sheets from your team should be flattened (remove working comments).
    • Clearly mark changes with clouds/deltas/bubbles so reviewers can see what changed.
  4. Rename the plan set to the next version number (e.g., v2 → v3).
  5. Complete the Revision Form and save it with a clear name like Letter - [Project Address] - v1.
  6. Email the revision form and the complete revised document set to buildingservices@fortcollins.gov.
  7. Don't upload the documents to the portal unless instructed.

Review Timeline and Inspections

  • Typical Review Time: 14 calendar days for building/zoning reviews of revisions.
  • Inspections can't be scheduled while the revision is under review — inspections pause until approval and re-issuance.
  • If you need inspections soon, try to schedule them before submitting the revision (when safe/possible).

Fees for Applicant-Initiated Revisions

  • Small (~$50): Minor layout or small structural edits (less than ~25% of floor area).
  • Medium (~$100): Larger residential changes or notable mechanical/structural work.
  • Large (~$200): Major commercial changes, change of occupancy, or increases in building size.

Actual fees depend on the scope of the change. These are representative categories — confirm with Building Services if unsure.

Stock Plan Revisions

  • Revising a stock plan replaces the prior approved set — future lots using that stock plan will use the revised set.
  • Ensure the revised set includes all required documents, not just the pages you changed.

Tips for the Revision Process

  • Be complete and clear — unclear changes cause delays.
  • Consider if your change triggers other departments (Zoning, Poudre Fire Authority, Utilities) and contact them if needed.
  • Versioning and consistent filenames keep records clean and reduce review friction.
  • Factor revision review time into your construction schedule.

Step 7: Final Inspections and Closeout Tasks

Project close-out is the final step in the building permit process. To close your permit, all required inspections and documents must be complete in Citizen Access.

1. Complete all tasks in Citizen Access

Make sure every task in your permit’s workflow is marked complete. Until everything is done, your permit will not show as Completed.

Important: If your permit expires without completion, it becomes an open code violation on the property.

2. Certificate of Occupancy or Letter of Completion

  • Certificate of Occupancy (CO) – issued for new buildings or when there’s a change of use or occupancy.
  • Letter of Completion (LOC) – issued for projects such as shell-only buildings, remodels, or non-occupiable work.

3. Department Requirements

The following departments must complete reviews or receive final documentation before your project can be closed:

Department / Task What You Must Do Contact / Notes
Building Final Documents Email required Final Building Document List following naming instructions. BuildingDocs@fortcollins.gov (Estimate 24-48 hours for review)
Building Inspections Schedule and pass all required building inspections. Must be complete before close-out
Electric Meter Verification Verify meter tagging and energize all units (for multi-unit or complex projects). 970-224-6093 (Meter/Electric)
Engineering Final (Site/Drainage) Provide engineer’s certification of drainage or lot grading compliance. WaterUtilitiesEng@fortcollins.gov (Estimate 2 weeks for review)
Stormwater / Erosion Upload required erosion control or floodplain reports and certificates, if applicable. erosion@fortcollins.gov (Estimate 2–3 weeks for review)

4. Key Reminders

  • All required inspections and documents must be complete before your project is marked Completed in Citizen Access.
  • Incomplete submissions delay occupancy or can result in violations.
  • Start final documentation and schedule inspections early to avoid delays.
  • Some departments have longer review timelines—plan ahead.

Additional Notes

Why Permits Matter: Permits protect public safety, ensure code compliance and support property value. Work without a permit may cause problems when selling a home or result in code enforcement actions.

Timelines: Large projects may require multiple rounds of review; plan accordingly.

Posting Permits: Always post your permit visibly at your work site.

Expired Permits:

  • Permit Applications can expire in 180 days (if not issued).
  • Permits that are issued and under construction expire in 180 days of inactivity (if inspections aren't performed or if other final tasks aren't completed). Each inspection extends the permit an additional 180 days.
  • Stock plans expire the day new codes are adopted and a new stock plan will need to be submitted.
