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.

  2021 IFC (International Fire Code) and the 2025 Colorado Wildfire Resiliency Code (rendered 'CWFC' on the Town's own Building page, elsewhere labeled 'CWRC' and cross-referenced to Municipal Code Article 14) — both became effective 7-1-2026 per the Town's Building Department page, which as of the verification date is already in effect (the page's own text is still phrased as 'WILL BE EFFECTIVE 7-1-2026', but that date has now passed).

Permit types & fees

• New Single-Family Dwelling, Duplex, or Townhouse Building Permit

  Required for new single-family residence, duplex, or townhouse building construction in the Town of Carbondale, regulated under the Town-adopted 2021 IRC and 2021 IBC (Ordinance No. 3/2025, effective 7-1-2025). Building Permit fees are valuation-based per the Town's Appendix A fee bracket table, plus a 65% plan review fee.

  From$27.50→

• Residential Addition Building Permit

  Required for additions to existing single-family, duplex, or townhouse structures in Carbondale. Uses the same valuation-based Building Permit fee table as new residential construction, plus Planning Department review (unlike a straight remodel).

  See fee schedule→

• Residential Remodel Building Permit

  Required for interior/exterior remodels of existing single-family, duplex, or townhouse structures in Carbondale that do not add floor area. Skips Planning Department review (N/A) but still requires Administrative and Building Department review.

  See fee schedule→

• New Commercial Building Permit

  Required for new commercial building construction in Carbondale, regulated under the Town-adopted 2021 IBC. Carries the longest published Building Department review window of any Carbondale permit type.

  See fee schedule→

• Commercial Remodel / Tenant Finish Permit

  Required for commercial remodels and tenant-finish build-outs in Carbondale.

  See fee schedule→

• Commercial Addition Permit

  Required for additions to existing commercial buildings in Carbondale.

  See fee schedule→

  From$75.00→

  From$75.00→

  From$200.00→

• Re-roof, Window, and Door Replacement Permit

  Required for roof replacement/repair and window/door replacement in Carbondale, per Appendix A items 2 and 4. This is the fastest-reviewed permit category the Town publishes besides Plumbing/Mechanical/Solar.

  From$150.00→

• Fence Permit

  Required for new fence construction/repair in Carbondale, per Appendix A item 7.

  $50.00→

• Demolition Permit

  Required for demolition of a structure in Carbondale where the building is not going back in its original place; demolition of a structure that IS being rebuilt in place is instead included within the residential/commercial building permit for that project.

  $75.00→

• Electrical Permit (State-Issued)

  Electrical work in Carbondale is permitted and inspected by the Colorado State Electrical Board (Division of Professions and Occupations), NOT by the Town of Carbondale — Carbondale does not operate its own local electrical inspection program. The Town's own permit-type list identifies this permit as 'electrical (State)', and Appendix A's Fee Schedule contains no Town-collected electrical permit fee line, consistent with the Town deferring this permit type entirely to the State.

  Fee not published→

• EV Charger / EVSE Permit

  Carbondale does not publish a standalone EV-charger/EVSE permit type. Installing electric vehicle charging equipment (e.g., a new 240V Level 2 circuit) is electrical work, and per the Town's own permit-type list and the separate 'electrical-permit' entry, ALL electrical permits and inspections in Carbondale are issued and inspected by the Colorado State Electrical Board (Division of Professions and Occupations / DORA) — the Town has no local Electrical Inspection Program. Colorado's HB24-1173 (Electric Vehicle Charging System Permits Act, effective August 7, 2024) sets a December 31, 2025 compliance deadline for standardized EV-charging permitting only for municipalities with population 10,000+ and counties with population 20,000+; Carbondale's 2024 Census population estimate is approximately 6,700-6,800, below that municipal threshold, so the Town is not required to adopt a distinct EV-charging permitting process under this law. No Town ordinance, Building Department page, or Appendix A Fee Schedule line item referencing EV chargers, EVSE, or HB24-1173 was found as of the last verification.

• Sign Permit (Street Graphics Permit)

  Required for signs in Carbondale, administered by the Planning Department rather than the Building Department — a different routing than every other permit type in this record. The Town's own downloadable checklist is titled 'Sign Permit Checklist,' but the actual fillable application form it links to is titled 'STREET GRAPHICS PERMIT APPLICATION,' per the Town's document center (carbondalegov.org/document_center/Planning/Sign_Permit_Checklist.pdf, fetched and read directly as a two-page PDF: page 1 is the checklist, page 2 is the application form itself). Reviewed and approved by the Planning Director per Unified Development Code (UDC) Section 2.3.2.B.

  From$35.00→

• Fire Sprinkler and Fire Alarm System Permit

  Required for installation, modification or alteration of automatic fire sprinkler systems and fire alarm systems in Carbondale. Plan review, permitting and inspection for these systems is performed by the Carbondale & Rural Fire Protection District, a special district separate from the Town of Carbondale Building Department — confirmed via CRFPD's own 'Prevention Permit Fees' page (carbondalefire.org/prevention-permit-fees). Do not confuse it with the Roaring Fork Fire Rescue Authority, which covers neighbouring jurisdictions. This mirrors the carve-out already documented for electrical work here, which routes to the Colorado State Electrical Board rather than the Town: the Town's own Appendix A Fee Schedule contains no sprinkler or fire-alarm fee line despite itemizing every other trade — building, mechanical, plumbing, solar, roofing, fence and demolition — consistent with CRFPD, not the Town, being the permitting authority for this work.

  From$400→

• Change of Use / Conditional or Special Use Permit (Table of Allowed Uses)

  Carbondale has no standalone 'change of use permit' by that name — confirmed by a full-text search of the Town's own published Unified Development Code (UDC, Chapter 17 of the Municipal Code, Amended January 2025), which contains zero instances of the phrase 'change of use' anywhere in the document. A change limited to a commercial space's IBC occupancy classification for construction purposes (e.g., a tenant finish) is instead captured within the ordinary Town Building Permit process already documented in the commercial-remodel-tenant-finish-permit and new-commercial-building-permit entries. A genuine change to a NEW land use at the zoning level is governed by the UDC's Table 4.2-1 (Table of Allowed Uses), Chapter 17.04: each use is classified per zone district as Permitted ('P'), Conditional ('C'), Special ('S'), or prohibited (blank cell); moving into a 'C' or 'S' use requires a Conditional Use Permit (UDC Section 2.5.1) or Special Use Permit (UDC Section 2.5.2), respectively, both reviewed and decided by the Planning Director.
