Codes adopted

Colorado has no statewide-mandated building code edition. Under the Colorado Constitution's home-rule provisions (art. XX, home rule for municipalities since 1902; home rule for counties since 1970), building codes and zoning are an enumerated home-rule charter power, so cities and counties adopt and amend their own construction codes independently — predominantly the I-Codes, with editions and local amendments varying by jurisdiction. The one statewide floor is for energy: HB22-1362 (2022) created the Energy Code Board (jointly appointed by the Colorado Energy Office and the Department of Local Affairs) and requires that, on or after July 1, 2023 and before July 1, 2026, any municipality or county that adopts or updates a building code must adopt and enforce an energy code achieving performance equivalent to or better than the 2021 IECC together with the board's Model Electric Ready and Solar Ready Code (which includes electric-ready, EV-ready, and solar-ready provisions); from July 1, 2026 onward the floor shifts to the board's Model Low Energy and Carbon Code or an equivalent. Electrical and plumbing permitting defaults to the Colorado State Electrical Board and State Plumbing Board (within DORA's Division of Professions and Occupations) — the state issues permits and inspects statewide except in counties/jurisdictions that operate their own certified Electrical or Plumbing Inspection Program, in which case the local program has authority instead. Always confirm the currently adopted code edition, local amendments, and inspection authority (state board vs. local program) with the specific jurisdiction before submitting plans.

Permit types & fees

• Residential Building Permit (New Construction)

  Required for new single-family homes, duplexes, townhomes, and similar residential structures within Town of Mt. Crested Butte limits. Reviewed under the 2021 IRC as locally amended (Town Code Chapter 6, Article III), including the Town's Table R301.2 climatic design criteria (155 psf ground snow load, 105 mph wind design speed, Seismic Design Category B, 9,400 ft Manual J elevation), a stricter automatic fire sprinkler trigger than neighboring Crested Butte, and a concurrent Design Review + Permit Review process administered directly by the Community Development Department.

  From$23.50→

• Residential Addition / Remodel Permit

  Required for additions, interior remodels, and exterior remodels to existing residential structures in Mt. Crested Butte, per the Town's own Permit Policy document covering remodels, additions, repairs, excavation, and driveway improvements. Reviewed under the 2021 IRC and IEBC as locally amended (Town Code Chapter 6); additions of 1,000 sq ft or more that bring total gross floor area to 4,800 sq ft or more trigger whole-structure fire sprinkler requirements.

  From$23.50→

• Mechanical / HVAC Permit

  Required for heating, cooling, ventilation, and appliance installation, alteration, or repair in Mt. Crested Butte. Governed by the 2021 International Mechanical Code (IMC), adopted by Town Code Chapter 6, Article IV, with a locally set flat-fee Table 1-AM schedule (Town Code Sec. 6-75) rather than a valuation-based fee.

  From$50.00→

• Roofing Permit (Re-Roof)

  Required for re-roofing work in Mt. Crested Butte, reviewed under the 2021 IBC/IRC as adopted, with mandatory ice barrier underlayment per Table R301.2. If the re-roof affects 25% or more of the structure, the entire roof must meet Colorado Wildfire Resiliency Code (WRC) Class A roof-covering, valley-flashing, and vent-mesh requirements per the Town's own WRC Standards Summary.

  From$100.00→

• Solar Photovoltaic (PV) Permit

  Required for rooftop or ground-mounted solar photovoltaic installation in the Town of Mt. Crested Butte. The Town's own Building Division does NOT issue or inspect electrical permits at all — electrical work, including PV wiring and utility interconnection, is handled entirely by the Colorado State Electrical Board (Division of Professions and Occupations), capped at $500 for a residential permit and $1,000 for a commercial permit under the statewide solar permit fee cap, C.R.S. § 24-48.5-113 (HB21-1284). The Town's own Building Permit (valuation-based Table 1-A fee, or the Design Review 'no drawings/engineering' $100 fee for simple roof-mounted work) covers only the structural/mounting scope. The Town has adopted the Model Colorado Electric and Solar Ready Code provisions for new construction.

  From$69.25valuation-based→

• Electric Vehicle (EV) Charger Permit

  Required for installing a new electrical circuit, outlet, or panel/service upgrade to serve an EV charger in the Town of Mt. Crested Butte. As with solar PV interconnection work, the Town's Building Division does NOT issue or inspect electrical permits of any kind — all electrical work, including a new EV charger circuit, is handled directly by the Colorado State Electrical Board (Division of Professions and Occupations), independent of the Town's own Building Permit process (which only applies if structural work, such as a new garage, accompanies the charger installation).

• Commercial Building Permit (New Construction, Addition & Tenant Improvement/Alteration)

  Required for new commercial construction and for tenant improvement/alteration work in existing commercial buildings within Town of Mt. Crested Butte limits — including hotel, condo-hotel/accommodation, retail, restaurant, and other non-single/two-family occupancies, and Downtown Development Authority (DDA) District development. Reviewed by the same Community Development Department (Building Division) as residential permits, under Town Code Chapter 6, Article II (2021 IBC, as locally amended by Ordinance No. 6, Series 2024) for new construction and Article IX (2021 IEBC) for alterations, using the SAME GovWell application portal and the SAME valuation-tiered Table 1-A Building Permit Fee schedule as residential (Sec. 6-21, citing IBC Sec. 109.2) — the residential-building-permit entry documents that Table 1-A and the parallel residential Table R1-A are identical schedules. The Town's own Fee Schedule (Resolution No. 9, Series 2026) does set a distinct, higher Design Review fee category for 'Accomdation [sic] Units, and Commerical [sic] Unit[s]' compared to Single Family Residence or Multi-Family Residential Design Review fees. No standalone commercial-specific building permit application form, submittal checklist, or Tenant Improvement Permit fee/application track distinct from this general process was found published by the Town.

  From$23.50→

• Sign Permit

  Town Code Chapter 16 (Signs and Advertising), Article II, governs sign permitting in Mount Crested Butte. A permit is required to construct, erect, remodel, move, or otherwise change or affect any sign within town limits, except signs listed as exempt; the Zoning Administrator processes applications. No permit is required to maintain a sign in good repair, or for a change of copy where the business and sign remain conforming.

  From$50.00→

• Fire Sprinkler / Fire Alarm System Permit

  Fire protection and fire-code plan review for Mount Crested Butte is provided by the Crested Butte Fire Protection District (CBFPD), a special district separate from Town government (300 County Road 317, Crested Butte, CO 81224; 970-349-5333). New construction and alteration plan review (Section 1001 of CBFPD's Fire Prevention Fee Schedule) is valuation/square-footage based and explicitly includes plan review and inspection of automatic fire suppression systems and/or monitored fire alarm systems where required — CBFPD does not publish a separate stand-alone sprinkler/alarm permit fee line distinct from this bundled new-construction review.

  From$700→

• Change of Use / Change of Occupancy

  The Town of Mt. Crested Butte publishes no standalone 'Change of Use' or 'Change of Occupancy' permit application distinct from the general Community Development Department building-permit process — none appears on the Town's Building, Building Permit Applications, or Building Policies/FAQs pages.
