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 and similar new residential construction in Firestone. Reviewed under the 2018 IRC/IBC as locally amended by Ordinance No. 1029 (the 'Firestone Building and Construction Code'). Plan review/permit administration is handled by Town of Firestone Building Division staff; inspections are performed by SAFEbuilt Colorado under contract.
From$80Residential Addition / Remodel Permit
Required for additions, basement finishes, and remodels involving structural changes in Firestone. Reviewed under the 2018 IRC as locally amended. Basement Finish/Remodel and Addition are both explicitly listed among the Town's permits requiring plan review.
From$80valuation-basedElectrical Permit
Required for electrical modifications, service upgrades, and panel/meter work in Firestone. Governed by the 2023 NEC as locally adopted. Residential electrical permits are billed on a distinct area-based fee schedule; several standalone electrical items (temporary construction meter, service replacement, mobile home electrical set) carry flat fees.
From$141.20Plumbing Permit
Required for plumbing modifications, backflow preventers, water heater replacement, and new gas lines in Firestone. Governed by the 2018 IPC and IFGC as locally adopted.
From$141.20Mechanical / HVAC Permit
Required for furnace, A/C, and related HVAC equipment installation or replacement in Firestone. Governed by the 2018 IMC and IFGC as locally adopted.
From$132.00Roofing Permit (Reroof)
Required for re-roofing in Firestone. Governed by 2018 IRC roofing provisions with a dedicated Town-published Reroof Requirements guide (REV 8.11.23) covering asphalt shingle re-roofing specifics.
From$132.00Solar PV Permit
Required for solar panel installation in Firestone. Governed by the 2018 IBC/IRC and 2023 NEC as locally adopted. The Town publishes a dedicated 'PV Solar Detach-Reset Process' guide for re-roofing under existing solar arrays, and solar installs carry a capped electrical permit fee distinct from the general residential electrical fee table.
From$500Demolition Permit
Required for residential demolition in Firestone, listed as a distinct flat-fee permit item on the Town's Building Division Fee Schedule.
$132.00Fence Permit
Required for residential fences under 6 feet in Firestone, listed as a distinct flat-fee permit item. No published guide or fee was found specifically for retaining walls, so this entry is scoped to fences only, per the genuinely-sourced fee schedule line item.
$132.00EV Charger / Energy Storage System (ESS) Permit
Firestone publishes a dedicated 'Firestone Single Family EV Car Charger and/or Energy Storage System' requirements guide (Rev 3.26.2024), distinct from its general Building Guides. New residential EV charging systems and/or energy storage systems use an 'RES inspection type' for all inspections, with specific plan-review submittal items, a 2023-code local amendment requiring a heat detector interconnected to the home's smoke detector system when an attached garage has an EV charger (per NFPA 70 Article 625), and detailed ESS placement/energy-rating rules (IRC Section R327, locally amended). Billed under the same area-based Residential Electrical Permit fee table documented in the electrical-permit entry — no distinct EV/ESS fee line was found on the Fee Schedule.
From$141.20valuation-basedCommercial Building Permit (New Construction / Additions)
Required for new commercial buildings and additions thereto in Firestone. Reviewed under the 2018 IBC as locally amended by Ordinance No. 1029 (the 'Firestone Building and Construction Code'), with the 2023 NEC for electrical scope. Firestone publishes a dedicated Commercial Permit Submittal Checklist (REV 03.25) distinct from residential submittals, and a separate 2026 Non-Residential Fees sheet covering water tap, impact, and use-tax charges layered on top of the standard valuation-based Building Permit Fee. All plans must be stamped by a Colorado Licensed Architect and Colorado Registered Engineers. Plan review/permit administration is by Town staff; inspections are performed by SAFEbuilt Colorado under contract.
From$80valuation-basedCommercial Tenant Finish (Tenant Improvement) Permit
Required for tenant finishes in existing commercial buildings in Firestone. Genuinely distinct from the new-commercial process: the Town publishes a separate 'Commercial Tenant Finish Permit Submittal Checklist' (REV 04.24) with its own scope — no civil package or soils report required, structural documentation only if applicable, change-of-occupancy analysis when the use changes, and energy code documentation typically only for previously unoccupied shell spaces. Plans must still be stamped by a Colorado Licensed Architect and Colorado Registered Engineers, and separate submittals to the Frederick-Firestone Fire District and St. Vrain Sanitation District are still required. Fees run through the same valuation-based Building Permit Fee Table — there is no distinct TI fee line.
From$80valuation-basedSign Permit
Required to display, construct, install, erect, remodel, relocate, expand, or alter any sign within Firestone town limits — including a copy change — per Firestone Development Code (FDC) Section 16.6.12(D). The sign-permit requirement, the fee-by-reference rule, and the design and temporary-sign standards below come from the Firestone Development Code, February 2025, which the Town publishes in full on firestoneco.gov. The Town also publishes a Sign Permit Submittal Checklist (REV 4.24) and a Building Division Fee Schedule (REV 01.2025); the fee schedule carries no standalone sign fee line item, so the sign fee is set by reference through the general building permit fee.
From$80valuation-basedFire Sprinkler and Fire Alarm System Permit
Colorado is home-rule with no statewide fire code floor, so which authority governs fire sprinkler/alarm work in Firestone had to be independently confirmed rather than assumed. Firestone has NO Town-run fire department -- fire-code plan review, permitting, and inspection for fire alarm and fire sprinkler systems are handled directly by the Frederick-Firestone Fire Protection District (FFFPD), a special district under Title 32, C.R.S. The localAmendments and commercial-building-permit/commercial-tenant-improvement-permit entries already note that multi-family and all commercial projects require FFFPD approval (303-833-2742), but FFFPD's own direct process had not previously been documented as its own permit type. RESEARCHED 2026-08-13: every fact below was read directly from FFFPD's own 2026 Fee Schedule PDF, Application for Plan Review PDF, and Submittal Requirements for Plan Review PDF (all downloaded and read directly), not inferred or search-summarized. Carries 'verified' confidence on that basis.
From$300.00Change of Use / Change of Occupancy Permit
Firestone has no standalone 'change of use permit' application, fee, or numeric review timeline distinct from its general Commercial Building Permit / Commercial Tenant Finish process. The Town's own Firestone Development Code (February 2025) formally defines 'Change of Use' (Section 16.11.3, Definitions) as changing a building's or land's occupancy to a different permitted use, and treats it as a TRIGGER for other standards (Section 6.4 landscaping compliance, Section 6.6 off-street parking planning) rather than as a distinct permit type of its own. On the Town Building Division side, a change of use is processed through the same Commercial Building Permit or Commercial Tenant Finish Permit application already documented for this jurisdiction (whose own submittal checklist calls for a change-of-occupancy analysis only if applicable). Separately, FFFPD's own 2026 Fee Schedule explicitly names 'change of use' as one of the building modifications requiring its own Building Construction Permit, and St. Vrain Sanitation District separately reviews any change of occupancy that affects wastewater demand. The entry carries 'partial' confidence because the Town's published materials leave unclear whether a construction-free change of use (no accompanying trade work) still requires a full Building-Permit-fee submittal purely for occupancy sign-off.

Tips & gotchas
- Firestone splits its Building Division across two organizations: Town of Firestone staff handle permit intake/administration/plan review coordination, while SAFEbuilt Colorado (contracted) performs building inspections — know which to contact for which step of the process.
- Permits expire if work is not commenced within 180 days of issuance, if a required inspection is not requested within 180 days, or if 180 days lapse after a required inspection without a follow-up inspection/approval — and expire outright after 2 years regardless, unless the Building Official grants a written extension requested before expiration.
- Starting work before pulling a permit doubles the normal permit fee (plus a separate investigation fee) under Ordinance No. 1029 — always get the permit first.
- Firestone's electrical fees are indexed to the Denver-Aurora-Lakewood CPI and adjust annually under Colorado HB 19-1035 — always confirm current-year dollar amounts rather than relying on a prior year's published schedule.
- The Town's residential Building Guides (Basement Finish, Detached Garage, Enclosed Patio, One-Story Addition, Patio Covers/Carports, Pole Barn, Uncovered Decks) are generic Colorado Chapter ICC templates, not Firestone-specific requirement documents beyond the code edition reference — check the actual Firestone Municipal Code / Ordinance 1029 amendments for binding local rules, and confirm specifics with the Building Division for anything the generic template doesn't address.
- Multi-family and all commercial projects require separate approval from the Frederick-Firestone Fire Protection District (303-833-2742) in addition to Town Building Division review.
