Fee schedule

Requirements

• Frederick-Firestone Fire Protection District (FFFPD, 8426 Kosmerl Place, Frederick, CO 80504, 303-833-2742, fireprevention@fffd.us) is Firestone's fire-code plan-review and permitting authority for fire alarm and fire sprinkler systems -- consistent with the existing commercial-building-permit entry, which already directs multi-family and commercial submittals to FFFPD
• FFFPD issues permits for installation of any new fire alarm or fire sprinkler system -- including fire pumps, kitchen hood suppression systems, bi-directional amplification systems, AES Radio systems, and underground fire lines -- and for any modification to an existing system, per FFFPD's own 2026 Fee Schedule
• Fire Protection System Plan Review, Permit and Inspection Fees are assessed at 0.03 times the project value (materials and labor, as reported by the contractor), with a $300.00 minimum fee. If you are used to budgeting fire-protection review at a 0.025 rate, budget higher for work in Firestone.
• Submission is electronic only -- thumb drive, PDF by email, or a file-sharing service such as Dropbox or Citrix -- sent directly to fireprevention@fffd.us; required items are a completed and signed FFFPD Application for Plan Review, unlocked stamped Civil/Architectural/MEP drawings, and unlocked Fire Safety System shop drawings with data/cut sheets (fire alarm, fire sprinkler, hazardous materials, kitchen hood suppression, mobile food vehicle, etc.), per FFFPD's own Submittal Requirements for Plan Review document
• FFFPD does NOT accept deferred submittals except for Kitchen Hood Fire Suppression Systems and Commercial Paint Spray Booths -- all other fire protection systems must be part of the initial complete submittal
• All submitted documents/drawings must be stamped by an independent Colorado-licensed Engineer, Architect, or NICET Level III designer specializing in fire protection, including a written report on how the design meets the currently adopted International Fire Code and current NFPA Standards
• All fire suppression contractors and underground fire line installation contractors must be registered with the Colorado Division of Fire Prevention and Control, with current registration copies provided with every submittal
• No numeric review-timeline figure, minimum or maximum, is published anywhere in FFFPD's own Application for Plan Review form or Submittal Requirements document. If you have worked with a different Front Range fire district that states a minimum review period, do not assume the same applies here.

Required documents

• RequiredApplication for Plan Review (Frederick-Firestone Fire Protection District)Emailed to fireprevention@fffd.us; captures IBC construction type/occupancy class, IBC/IFC edition, gross square footage, and whether the building is protected by an automatic fire sprinkler system
• RequiredStamped Civil, Architectural, and MEP DrawingsUnlocked electronic drawings, per FFFPD's Submittal Requirements for Plan Review
• RequiredFire Safety System Shop DrawingsFire alarm and/or fire sprinkler shop drawings with data/cut sheets, unlocked
• RequiredColorado Division of Fire Prevention and Control Contractor RegistrationRequired for fire suppression and underground fire line installation contractors, provided with every submittal

Fee schedule

Requirements

• 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 record, 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 (the 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

Required documents

• RequiredBuilding Permit Application (Commercial Building Permit or Commercial Tenant Finish Permit, Online Portal)Same citizenserve.com/firestoneco submittal used for every other commercial/tenant-finish permit type in this record; a change-of-occupancy analysis is included in the architectural code analysis only if the use classification is changing
• OptionalFFFPD Application for Plan ReviewRequired if the change of use involves building construction/modification within FFFPD's jurisdiction (see the fire-sprinkler-alarm-permit entry for FFFPD contact info; the FFFPD-side Building Construction Permit fee is documented in this entry's fees)
• OptionalSt. Vrain Sanitation District ReviewRequired if the change of use affects wastewater demand, per the Town's own Taxes, Licensing & Permitting page
