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.
Reviewed 2026-08-02 · Source
Requirements
- Town Building Permit required for the array mounting/structural scope, submitted via the Town's GovWell online portal
- Electrical permit for PV wiring/interconnection must be obtained directly from the Colorado State Electrical Board (dpo.colorado.gov/Electrical), NOT from the Town — the Town's Building Division does not issue or inspect electrical permits
- Colorado State Electrical Board Solar/Alternative Energy System permits may use a SolarApp+ or Symbium expedited plan review pathway per the Board's published process
- State Electrical Board permit is valid for one year from the date of issuance
- Design Review approval required through the Community Development Department; a solar-only installation that does not require drawings/engineering (e.g., a straightforward roof-mount) falls under the $100 Design Review fee tier; installations requiring drawings/engineering are billed at the $200+ tier

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) — this file's 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.
Reviewed 2026-08-02 · Source
Requirements
- A current Gunnison County Building Contractor License (Class A, B, or C matching the scope of work) is REQUIRED on all commercial building permit applications, including additions and IEBC Level 2/3 alterations — Town Code Sec. 6-19(5) and Sec. 6-128 (Ordinance No. 6, Series 2024). Unlike residential, the owner-builder exception in Sec. 6-19(5) applies ONLY to property owners of an individual R-1, R-2, or R-3 UNIT acting as their own contractor — a genuinely commercial (non-residential) occupancy has no owner-builder exception at all
- Site survey/plat by a Colorado-licensed land surveyor is required for new construction, but is explicitly WAIVED under Town Code Sec. 6-19(2) when 'a building permit is sought to reconstruct or remodel totally within the limits of an existing building or structure' — i.e., a typical tenant improvement/interior remodel confined to an existing shell does not require a new survey/plat
- Crested Butte Fire Protection District (CBFPD) approval letter required confirming access, gas meter location, and water supply comply with Town Code Chapter 8 (Sec. 6-19(3))
- Construction Management Plan (CMP) required, addressing on-site parking, material staging, road cleaning, trash/toilet facilities, temporary safety fencing, hours of construction, traffic control, snow storage/removal, dust mitigation, and sediment/erosion control (Sec. 6-19(4))
- Evidence of Mt. CB Water & Sanitation District tap fee payment, or a written waiver signed by the District's superintendent, required before permit issuance if the project taps into the water/sewer system (Sec. 6-19(6))
- Design Review and Permit Review are conducted CONCURRENTLY through the Community Development Department, per the Town's general (not commercial-specific) combined-process description; Design Review approval, once granted, is valid for 1 year. Proposed development within the Downtown Development Authority (DDA) District receives additional Community Development Department review for DDA compliance, per the Town's own description of the Building Division's role
- Design Review Scheduling Floor — CONFIRMED THIS SESSION (2026-08-02) directly from Town Code Chapter 21 (Zoning), Article V (Design Review), Sec. 21-303 (Approval Procedure), a genuinely new source for this file (via ecode360.com/MT4975): design review for any development OTHER than 'single-family residential areas of PUDs and the SFR zone districts' (Sec. 21-303(a), handled administratively by the zoning administrator, no fixed timeline) — i.e., essentially all commercial/Business District/Commercial District/PAD development — is decided by the Planning Commission, and Sec. 21-303(b) requires the zoning administrator to schedule that hearing 'no less than 14 days and no later than 28 days after the receipt of all such materials.' This is a genuine numeric floor for scheduling the initial hearing, NOT a guaranteed decision/completion time: Sec. 21-303(d) lets the Planning Commission table or continue action 'to a date certain' with no outer limit stated, and the separate concurrent Building/Permit Review step (Article II of Chapter 6, IBC Sec. 105.3, re-confirmed this session to be amended only to add application-content subparagraphs, NOT a review-turnaround timeframe) still carries no Town-published numeric SLA at all
- Downtown Development Authority (DDA) Carve-Out — Town Code Sec. 21-301(d): commercial/development projects within the DDA District boundary do NOT follow the Sec. 21-303 procedure above at all; they instead 'shall follow the design review policies and design standards of the Mt. Crested Butte Downtown Development Authority Architectural and Site Design Standards,' a separate DDA-authored document. That document was checked for this session directly on the Town's DDA page (mtcb.colorado.gov/government/downtown-development-authority-dda) and was not found published/linked there — its own review timeline, if any, remains unconfirmed
- Fire alarm systems, where required by IBC Sec. 907.2, must meet International Fire Code Sec. 907.8.2 as identified in Town Code Chapter 8 (Sec. 6-25)
- Ice barrier underlayment required on all roofs (Sec. 6-31, amending IBC Sec. 1507.2.8.2), except detached accessory structures without conditioned floor area
- Design snow load of 155 psf per the 2016 SEAC Colorado Design Snow Loads (Sec. 6-32, amending IBC Sec. 1608.1) applies to commercial construction the same as residential
- Minimum footing depth of 36 inches below finished grade unless an alternative is engineer-recommended (Sec. 6-33)
- No local IBC-Article-II amendment to Chapter 9 (Fire Protection Systems) automatic-sprinkler trigger comparable to Article III's residential Sec. 6-59 was found — commercial sprinkler requirements were not confirmed to follow a Town-specific threshold and should be assumed to follow the unamended 2021 IBC Chapter 9 provisions by occupancy/area unless the Building Division states otherwise
- Tenant improvements/alterations to existing commercial buildings are governed by the IEBC (Town Code Article IX, Sec. 6-126 et seq.) as Level 1/2/3 alterations; Level 2/3 alterations require the same Gunnison County Contractor License proof as new construction (Sec. 6-128)
- Electrical and plumbing work is NOT reviewed or inspected by the Town — those permits/inspections are obtained separately and directly from the State of Colorado (Colorado Electrical Board and Colorado State Plumbing Board), the same statewide carve-out documented for residential permits in this file
- 3% Use Tax on construction/building materials, calculated on 50% of estimated total valuation (or documented actual materials valuation), reconciled within 90 days of Certificate of Occupancy issuance or final inspection approval — Town Code Sec. 19-105/19-21, which is not restricted to residential projects
