Fall Is a Great Time to File Building Permits in Aspen

If you’re planning a design project, remodel, or repair in Aspen or Pitkin County, fall 2026 is the time to get started. The Aspen/Pitkin County Airport, also known as Sardy Field, is scheduled to close to all aircraft operations from April 4, 2027, at 11:00 p.m. through November 19, 2027, at 7:00 p.m. Getting your plans and project logistics organized early can help you prepare for the 2027 building season.

Permits can add cost and complexity to a project, and the process can be frustrating. But waiting too long can create even bigger challenges—especially if your plans need review, revisions, or additional approvals.

Start early, especially for larger projects

For City of Aspen permits, the published average first review round for a new major residential permit is 16–18 weeks. Each additional major review round averages another 8–10 weeks. These timelines begin once the application is complete and applicable fees are paid, and they can change with the review queue and project requirements. Smaller projects may move faster: the City lists 3–4 weeks for a new mini permit’s first review round and 2–4 weeks total for repairs. These are estimates, not guarantees. (ASPEN)

A smaller repair or remodel may still be possible before April, depending on the scope and review process. If you’re hoping to do work during summer 2027, start planning now rather than waiting until spring.

Get the complete application package together

A permit application can require more than a project description and drawings. Depending on the scope and jurisdiction, the application package may include signed HOA compliance forms or approvals, ECU calculations, an affidavit of value, asbestos documentation, a contact sheet, and other supporting materials.

An ECU is an Equivalent Capacity Unit, used by the City to calculate water-system capacity and related requirements for certain projects. The City’s online permit document library and application resources list forms and supporting documents that may be required. The specific checklist depends on your project, so confirm the requirements with the correct building department. (ASPEN)

For second-home owners, it helps to make sure your owner representative or project manager has the pertinent contact information ready before the application is filed. Confirm who should receive permit notices and review comments, and gather any required owner authorization and HOA information. Missing forms or details can keep an application from being deemed complete, trigger additional requests, and delay permit review or issuance.

Check asbestos requirements before demolition or repair

Asbestos testing is an important part of many City of Aspen building applications. For residential work, the City checklist calls for testing when removal exceeds 32 square feet, 50 linear feet, or the volume equivalent of a 55-gallon drum of certain materials, including drywall, linoleum, ceiling tile, and roofing. Concrete, wood, bricks, and steel are listed as exceptions. The test trigger is not limited to removing more than 55 gallons, so check the current requirements for your project before work begins. 

Some samples may come back at 1% or less, but don’t assume that result automatically means you can proceed without further review. Ask the City and a qualified asbestos professional how the test results apply to your material and project. If asbestos is identified and will be disturbed, the City’s materials call for required abatement documentation and clearance before the related permit is issued.

Budget and schedule for professional abatement

Asbestos abatement in Aspen can be expensive. In our experience, specialized crews may travel from Grand Junction or Denver to work in the Roaring Fork Valley, adding mobilization costs and scheduling considerations. Get estimates early and make sure the work is handled by appropriately certified professionals.

Be cautious of anyone who proposes skipping required testing, approvals, or permits for the repair or reconstruction work. The City notes that asbestos abatement itself does not require a City of Aspen permit, but that does not mean related building work or state requirements can be ignored. Confirm which requirements apply before work begins. 

Not every project needs a permit—or detailed architectural plans

Not all permits require detailed architectural plans, and some minor repairs may not require a permit at all. The City of Aspen publishes examples of projects typically exempt from construction permits, but requirements depend on the work and property—and other approvals may still apply. Check with the appropriate building department before starting. 

The bottom line

Permits add cost and complexity, and for many owners the process can feel like an unnecessary expense and a frustrating hurdle. Aspen Home Improvement can help you understand the process, organize the application package, and plan the next steps.
