Change of Use / Change of Occupancy Permit in Firestone, Colorado

Firestone requires a change of use / change of occupancy permit for: Firestone's own Development Code formally defines 'Change of Use' (Section 16.11.3, Definitions): the act of changing the occupancy of a building or land from a use specifically listed as a 'Permitted Use,' covering (a) a single-tenant building's or parcel's occupancy changing from its most recent use to a different one, (b) a tenant space in a multi-tenant building changing to a use not currently existing (or not existing within the last 12 months) elsewhere in the building, or (c) reestablishing or changing use after a 12-consecutive-month abandonment of the prior use; FDC Section 16.6.4(B)(3) (Landscaping) lists 'any change of use from one primary use classification to another (for example, residential use to commercial use)' as one of three triggers -- alongside additions and floor-area/story increases -- that require compliance with the Town's landscaping standards (Section 6.4); FDC Section 16.6.6 (Off-Street Parking) separately flags that development with approvals permitting a future change of use requiring additional parking must reserve undeveloped on-site area to accommodate those future parking needs; No standalone Town of Firestone 'change of use permit' application, fee, or numeric review timeline is published on the Building Permits & Fees page, Building Submittal Requirements page, Building Guides page, the Development Code itself, or the Building Division Fee Schedule (REV 01.2025) -- checked all directly; a change of use is instead processed through the same Commercial Building Permit or Commercial Tenant Finish Permit application already documented in this file, whose own checklist requires a change-of-occupancy analysis only if the project changes the occupancy classification; FFFPD's own 2026 Fee Schedule explicitly names 'change of use' as one of the building modifications (alongside new building construction, remodel, and tenant finish) requiring its own separate Building Construction Permit -- billed at 0.0018 times the project valuation with a $300.00 minimum fee (fire alarm/sprinkler system valuations may be subtracted from the total project valuation); this FFFPD-side permit is separate from, and in addition to, both the Town's own Building Division review and FFFPD's own fire-protection-system-specific permit (this file's fire-sprinkler-alarm-permit entry); Saint Vrain Sanitation District separately reviews plans for any 'expansions or change of occupancy that affects the demand for wastewater services,' per the Town's own Taxes, Licensing & Permitting page -- a third, independent review layer distinct from both the Town Building Division and FFFPD; FFFPD's own fee schedule explicitly states its building construction permits are NOT required to construct, remodel, or renovate one- or two-family homes or townhomes -- so the FFFPD-side change-of-use fee applies to commercial/multi-family change-of-use projects, not residential ones. If your project isn't listed, confirm with Town of Firestone Building Division (plan review/permit administration by Town staff; building inspections contracted to SAFEbuilt Colorado) at 303-833-3291 before starting work.

The same fees as the underlying Commercial Building Permit or Commercial Tenant Finish Permit, plus a separate Frederick-Firestone Fire Protection District Building Construction Permit fee (0.0018 times the project valuation, $300.00 minimum) -- the Town's own materials do not publish a standalone change-of-use fee, but FFFPD's own 2026 Fee Schedule confirms change of use as one of the building-modification types billed under its 0.0018 formula.

Firestone does not publish a plan-review timeline for this permit. Contact Town of Firestone Building Division (plan review/permit administration by Town staff; building inspections contracted to SAFEbuilt Colorado) at 303-833-3291 for current turnaround.

No standalone Town permit exists by that name. Firestone's own Development Code formally defines 'Change of Use' as a trigger for other standards (landscaping compliance, parking planning), and the building-permit-side process runs through the same Commercial Building Permit or Commercial Tenant Finish Permit application used for other commercial projects, with a change-of-occupancy analysis included only if the use classification is changing.
