Aspen Building Department 2026: Permits, Inspections & Services

Aspen Building Department Contact Information

The building division operates within the City of Aspen’s Community Development Department. The following official contacts help residents, property owners, architects, and contractors reach the appropriate city staff.

Which Building Permits Are Required in Aspen?

A permit is generally needed for new construction, additions, structural changes, many remodeling projects, and regulated electrical, plumbing, or mechanical work. The exact permit depends on what will be built, removed, repaired, or altered.

Common thresholds: Aspen’s guidance identifies permits for tents exceeding 400 square feet and temporary structures over 120 square feet or accommodating more than 10 people, subject to the specific requirements and exceptions for each type of structure.

Projects That May Not Need a Permit

Some ordinary finish work, including painting and tiling, is typically exempt. However, Aspen requires further review where work disturbs more than 32 square feet of underlying substrate because asbestos testing and a building permit may be triggered. The city’s roofing guidance also identifies roof patch repairs smaller than one square (100 square feet) as generally permit-exempt.

Minor maintenance exemptions do not automatically waive zoning, historic-preservation, or other approvals. Confirm your exact work before starting.

How to Apply for an Aspen Building Permit

Aspen uses its Salesforce system to receive building permit applications, documents, payments, and review responses. Register before preparing to submit because account activation is not necessarily immediate.

1. Confirm jurisdiction and permit need.

   Check that the property is within Aspen city limits and whether your project requires a permit. Review the city’s permit types and exemption guidance.

2. Register for the permit portal.

   Open Aspen’s permits page and select Register for Permit Portal. Account approval typically takes one to two business days. Use the emailed activation link within 72 hours.

3. Prepare the required documents.

   Gather the permit signatures packet, a separate PDF describing the scope of work, existing and proposed plans, and any structural, zoning, energy, or other supporting documentation relevant to the project.

4. Submit the application.

   Return to the permits page, select Log In / Apply for Permit, choose the correct permit category, complete the application fields, upload the documents, and submit.

5. Complete the review and payments.

   Pay applicable submittal fees, respond to all agency comments together, and pay issuance fees when the permit is ready. Monitor the application for correction requests.

6. Obtain the permit and close out the work.

   Keep the issued permit and approved plans at the job site, complete required inspections, and obtain final approval or occupancy documentation when applicable.

Documents to Prepare Before Submission

Most building permit applications require core plans and forms. Additional items depend on the construction scope.

• Permit signatures packet: Completed applicant, contractor, property-owner, and applicable HOA information.
• Project narrative: A clear PDF explaining existing conditions and exactly what work is proposed.
• Construction plans: Existing and proposed drawings showing building layout, all affected levels, and orientation, with plan sets separated by trade.
• Structural documentation: Engineer-stamped drawings or other required structural information for applicable wall, beam, structural opening, and new-construction work.
• Construction Management Plan: Required according to the scope and work area, including staging, deliveries, dumpsters, and right-of-way impacts where applicable.
• Additional reviews: Historic preservation, landscaping, grading, trees, water fixtures, energy compliance, and other approvals when triggered.

Additional Aspen-Specific Reviews

Aspen’s mountain environment and local land-use rules can add requirements beyond a standard building permit. Before finalizing plans, check these common triggers:

For projects in Aspen’s commercial core, the city’s EPIC (Expedited Permits in Commercial Zones) program may offer an accelerated review path for qualifying work. Eligibility must be confirmed with Building Support before proceeding.

Aspen Building Permit Fees and Payment Options

There is no single flat fee for every Aspen building permit. Charges depend on the type of work, construction valuation, review departments, and additional applicable assessments.

Permit-related costs may include plan review, issuance, engineering, zoning, mitigation, and other project-specific fees. The City provides a Building Permit Fee Estimator, but expressly states that its results are preliminary rather than final.

When and How to Pay

• Submittal fees: Pay when notified after the application is accepted as complete, if applicable.
• Issuance fees: Pay after the application reaches Ready for Issue status.
• Online e-check: The City lists a $1.50 flat processing fee for eligible e-check payments of up to $250,000.
• Credit card: Available through the permit portal, with an additional processing charge.
• Check: Mail or deliver payment payable to City of Aspen, Community Development, 427 Rio Grande Place, Aspen, CO 81611. Include the permit number or project address.

Important: Applicants generally have 180 days from Ready for Issue status to pay required issuance fees before the application expires. Contact the Chief Building Official in advance if an extension is needed.

Building Permit Review Times in 2026

Aspen publishes estimated review times by permit category. The following figures are from the city’s July 2026 update and are not guaranteed deadlines.

These estimates generally begin after the application is complete and required submittal fees are paid. Correction rounds add time; major residential projects can require another 8–10 weeks per additional review round.

How to Schedule an Aspen Building Inspection

Inspection requests must be submitted through the City of Aspen Permit Portal. Your permit must be in Issued status, and the required inspection types will be identified in your permit documents.

1. Open the City of Aspen Permit Portal and sign in.
2. Select the Request Inspection tab.
3. Choose your issued permit from the eligible permit list.
4. Select the required inspection type. If it is missing, use the portal’s Inspection not on the list option and follow the prompts.
5. Enter the requested inspection information and available scheduling details.
6. Complete the request and check that it appears in the portal with the appropriate status.

The City states that inspectors begin their routes in the morning. Requested late-day inspection times may not be accommodated.

What to Have Ready for Inspection

• The issued permit record posted visibly at the site.
• The full-color, stamped approved plans available for inspection.
• The relevant work completed to the required inspection stage, but not concealed prematurely.
• Safe access to the work and inspection areas.
• The required B.E.S.T.-certified individual present to meet the inspector, as applicable.

For failed inspections, correct the issues identified by the inspector before requesting reinspection. Aspen does not allow reinspection earlier than the day following the initial inspection.

Aspen Building Codes and Local Requirements for 2026

For building permits submitted after March 31, 2023, Aspen’s adopted framework includes the 2021 International Codes and local amendments. Aspen also has separate energy and wildfire-resiliency requirements.

Aspen City Council adopted the 2024 Colorado Wildfire Resiliency Code through Ordinance 6, 2026. This can affect construction and exterior building design, so verify wildfire-related requirements early in the design process.

Local Climate and Construction Design Criteria

Aspen’s published geographic design criteria include a 100 psf ground snow load, a 36-inch frost-line depth, and severe weathering classification. These are published reference criteria; actual structural design must follow the governing code and project-specific engineering requirements.

Energy compliance and the Renewable Energy Mitigation Program can be particularly important for heated outdoor features, certain mechanical systems, and larger construction projects.

Contractor Licensing and Owner-Builder Requirements

Contractors performing regulated construction work in Aspen generally need an applicable contractor license and a City of Aspen business license. Qualified contractors and job supervisors may also need an ICC certification or a relevant B.E.S.T. card.

Homeowners performing qualifying work on their own single-family residence may use the city’s homeowner-builder process instead of obtaining a contractor business license. This is not an automatic exemption from permits, testing, insurance, inspections, or other requirements.

Check Permit Status, Expiration, and Final Approval

To track an application, sign in to the Salesforce Permit Portal, locate the application, and review its status and agency review details. The portal also provides tools for communicating with city staff and submitting correction documents.

Pay attention to these important milestones:

• Completeness review: Additional documents may be requested before technical review begins.
• Permit review: Departments may approve or issue comments requiring resubmission.
• Ready for Issue: Required issuance fees must generally be paid within 180 days.
• Issued: The City requires qualifying inspection activity within each 180-day period to prevent permit expiration.
• Final approval: Following required passing final inspections and approvals, the City can issue the applicable Certificate of Occupancy or Letter of Completion.

For expired-permit concerns or extension requests, contact the Chief Building Official at bonnie.muhigirwa@aspen.gov before the deadline where possible.

If you need historical permit information, Aspen publishes annual permit application reports, including a 2026 report. These can contain permit numbers, property addresses, contractors, and project information.
