Within the Denver city limits, the responsibility for obtaining window replacement permits typically falls to the contractor.

While homeowners with a proper license may obtain them, it is generally preferred and expected that the professional contractor manages this process. This includes:

• Obtaining permits: Your contractor should secure all necessary building permits from the Denver city permitting office before any work begins.
• Managing inspections: The contractor is responsible for scheduling the required inspections to ensure the work meets local codes.
• Ensuring compliance: In Denver, most window replacements require a permit to ensure compliance with specific energy codes and egress requirements (especially for bedroom windows).

Professional teams like ACN Construction handle the entire permitting process as part of their design-build approach so homeowners do not have to navigate city offices alone.
