Tips
- BOZAR approval is a hard prerequisite to even submitting a building permit application in Crested Butte — budget at least 2 months for the BOZAR/DRC design-review cycle (the Town's own stated floor) before the Building Department's plan review even begins.
- Crested Butte's all-electric mandate and DOE Zero Energy Ready Home (ZERH) certification requirement took effect for permits starting January 1, 2026 — register as both an EENH Partner and Energy Star Partner and engage a HERS rater before applying; registration is required before a permit will be issued.
- Check the State of Colorado Wildfire Resiliency Map Viewer for your specific parcel — Crested Butte is mapped as a mix of Class 1 (lower intensity) and Class 2 (higher intensity) zones, so CWRC structure-hardening requirements are genuinely site-specific here, not a blanket town-wide rule.
- A Gunnison County building contractor license (not just a Town business license) has been required on every permit since February 1, 2023 — confirm your contractor holds this county-level credential. Contractor
- Single-family homes are exempt from Colorado's usual sprinkler expectations under Crested Butte's local IRC amendment, but any shared-wall product (duplex and up) is not.
