Commercial Building Permit (New Construction, Addition & Tenant Improvement/Alteration) in Mount Crested Butte, Colorado
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.

When you need this permit
- 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 Owner-builderContractor
- 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 — per Town Code Chapter 21 (Zoning), Article V (Design Review), Sec. 21-303 (Approval Procedure) (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, 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 is not published or linked on the Town's DDA page (mtcb.colorado.gov/government/downtown-development-authority-dda) — its own review timeline, if any, is 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) Contractor
- 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 record
- 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
- Contractor must hold a current Mt. CB Business License (BOLF)

Tips
- The Building Permit Fee, Plan Check Fee, Design Review Fee tiers, Table 1-B inspection fees, Design Review Compliance Deposit, and Use Tax all come from Ordinance No. 6, Series 2024 and Resolution No. 9, Series 2026. Two things those documents do not settle. First, the Town publishes no complete commercial-specific review timeline — only a 14-day minimum before the Planning Commission Design Review hearing can be scheduled, per Town Code Sec. 21-303(b), with no ceiling on total time. Second, the Design Review fee schedule does not clearly define when the flat 'Accommodation/Commercial Unit' tier applies versus the generic 'requires drawings/engineering' tier for a small single-tenant commercial space — confirm which tier applies to your project with the Town before budgeting.
- Unlike an individual condo/hotel unit owner (who may qualify for the R-1/R-2/R-3 owner-builder exception), a genuinely commercial building or tenant space has NO owner-builder exception — a Gunnison County Building Contractor License is mandatory on the permit application. Owner-builderContractor
- If your tenant improvement is confined entirely within an existing building's limits (a typical interior build-out), Town Code Sec. 6-19(2) waives the site survey/plat requirement that new construction needs — don't assume you need a new survey for a straightforward interior TI.
- The Building Permit Fee table itself (Table 1-A) is identical whether the project is commercial (IBC, Sec. 6-21) or residential (IRC, Sec. 6-52) — the cost driver is project valuation, not occupancy type. The genuinely different commercial cost driver is the Design Review fee tier and the mandatory (no-exception) contractor licensing requirement.
- Contact the Community Development Department directly (mtcb.colorado.gov/departments-services/community-development) before assuming a commercial project's review timeline — no published commercial-specific SLA exists beyond the 14-day minimum before a Planning Commission hearing can be scheduled, and DDA District projects receive an additional, separately-standarded compliance review layer.
- Unlike single-family residential design review (handled administratively by Town staff with no fixed timeline), a commercial project's Design Review must go before the Planning Commission — Town Code Sec. 21-303(b) requires the hearing be scheduled 14 to 28 days after a complete submittal, and the Commission can table/continue its decision further if it needs more information, so budget meaningfully more time than the residential-oriented 'up to 4 weeks' figure quoted elsewhere in this record.
- If your commercial project is within the Downtown Development Authority (DDA) District boundary, Town Code Sec. 21-301(d) routes you to a separate DDA-authored 'Architectural and Site Design Standards' document instead of the standard Sec. 21-303 Planning Commission procedure — confirm with the Community Development Department which track applies before assuming the general commercial timeline.
