Codes adopted
2021 International Building Code (IBC) as locally amended by Town of Basalt Ordinance (Chapter 18 amendments effective July 20, 2023) — confirmed via the Town's own 'Building' page code-adoption summary ('2021 ICC') and via the Town's detailed strike-through/underline local-amendment comparison document (2021-Code-change--ICC-reference-articles, basalt.net/DocumentCenter/View/6221)2021 International Residential Code (IRC), as locally amended — the Town's own Building Permit Application Checklist is titled for 'Single Family, Duplex, and Townhomes' built to the IRC2021 International Mechanical Code (IMC)2021 International Fuel Gas Code (IFGC) — State of Colorado adopted edition referenced alongside the Town's 2021 IBC/IRC/IMC cycle2021 International Existing Building Code (IEBC)2021 International Plumbing Code (IPC) — adopted at the State of Colorado level and applied by the Town2023 National Electrical Code (NEC) — per the Building Department page's current-adoptions summary; NOTE electrical work in Basalt is permitted and inspected by the State of Colorado Electrical Board, not the Town Building Department itself (confirmed directly on the Town's own Building Permit Application form: 'Electrical is permitted and inspected by the State of Colorado')2024 Sustainable Building Regulations I & II (SBRI/SBRII) — Town of Basalt Municipal Code Sec. 18-23/18-24/18-25, amended by Ordinance 20, Series of 2024, effective November 12, 2024, reflecting Holy Cross Energy's approximately 90% renewable power supply achievement by end of 2024Prior/superseded local design-parameter reference: the Town's 'Local Structural Design Parameters' document (basalt.net/documentcenter/view/2388) still headers itself against the 2015 IBC/IRC/IMC/IECC/IEBC code cycle and 2017 NEC/2015 IPC-IFGC — the numeric structural design values on that document (ground snow load, wind speed, seismic category, frost depth) are treated as still-current in this file because the Town's later 2021-code-adoption amendment document (View/6221) re-adopts the identical IRC Table R301.2(1) frost-depth (36 inches) and retaining-wall figures verbatim rather than superseding them; the code-EDITION labels on that older PDF itself are NOT current and should not be read as Basalt's current adopted code cycle.Local amendments to all adopted codes are codified in Chapter 18 (Building Regulations) of the Basalt Municipal Code; Municode's Basalt library returned an HTTP 403 to direct automated fetch in this session (library.municode.com/co/basalt) — the Town's own downloadable strike-through/underline amendment comparison document (View/6221) was used as the authoritative source for specific local IBC/IRC section amendments instead, since it is a primary Town document rather than a third-party mirror.

Electrical Permit
VerifiedRequired for installation, alteration, or repair of electrical systems anywhere in Basalt (both the Eagle County and Pitkin County portions of town). Unlike building, mechanical, and plumbing work, electrical permitting and inspection in Basalt is performed entirely by the State of Colorado Electrical Board (Division of Professions and Occupations), NOT the Town of Basalt Building Department.
Verified 2026-07-06 · Source
Requirements
- Permitted and inspected by the State of Colorado Electrical Board, not the Town of Basalt Building Department — confirmed directly on the Town's own Building Permit Application form
- Governed by the 2023 NEC as referenced on the Town's Building Department code-adoption summary
- Applied for through the Colorado Division of Professions and Occupations (DPO) Online Permitting System; the DPO encourages online purchase since permits are processed immediately upon payment through that system

- Electrical contractors must hold current State of Colorado electrical licensure per DORA Electrical Board requirements

EV Charger / EVSE Installation Permit
VerifiedBasalt has no separate Town-issued EV charger/EVSE permit or fee. Because ALL electrical work in Basalt (both the Eagle County and Pitkin County portions of town) is permitted and inspected by the State of Colorado Electrical Board rather than the Town Building Department, installing a home or commercial EV charging circuit is filed as a standard electrical permit through the Colorado Division of Professions and Occupations (DPO), the same carve-out that applies to all other electrical work in Basalt.
Verified 2026-07-20 · Source
Requirements
- EV charger/EVSE circuit installation is electrical work, and per the Town of Basalt's own Building Permit Application, ALL electrical work in Basalt is permitted and inspected by the State of Colorado Electrical Board (Division of Professions and Occupations), not the Town Building Department — no distinct Town-level 'EV charger permit' exists
- Applied for through the Colorado DPO Online Permitting System, governed by the 2023 NEC (including NEC Article 625, Electric Vehicle Power Transfer System) as referenced on the Town's code-adoption summary
- Colorado HB24-1173 (2024) established streamlined EV-charging-system permitting requirements, but only for counties with population 20,000+ and municipalities with population 10,000+; Basalt's population (~4,000-5,000) is below that municipal threshold, so the Town is not mandated to adopt HB24-1173's expedited local review procedures — electrical permitting for EV chargers in Basalt continues to run through the State DPO Electrical Board carve-out described above
- Electrical contractors must hold current State of Colorado electrical licensure per DORA Electrical Board requirements
- A separate Town of Basalt building permit may still apply to any non-electrical structural/site work associated with a charging installation (e.g., a new equipment pad or accessory structure), reviewed under the Town's standard building permit process
