EV Charger / Electric Vehicle Charging Station Permit
VerifiedRequired for installation of a residential or commercial EV charger in Fort Collins. Residential EV chargers for single-family detached/duplex/townhomes are Fast-Track eligible under the standard Electric permit; commercial and multifamily EV chargers use the valuation-based Remodel/Alteration permit fee table with a dedicated 'EV Charger (Commercial and Multifamily)' line item — both documented directly on the City's Building Permits page (Fast-Track Permits and Remodel and Alteration Permits sections).

- Master Electricians must be licensed by the State of Colorado (Supervisor relationship) AND separately register with the City of Fort Collins Contractor Licensing office

Sign Permit
VerifiedRequired to install, alter, or replace most permanent signs (wall, ground/monument, awning, projecting/fin, canopy, secondary roof) in Fort Collins, under Land Use Code Section 5.16 (Signs). Administered by the Zoning division of Community Development & Neighborhood Services — a distinct process from Building Services' Fast-Track/Remodel permits, with its own City-issued Sign Contractor license class. Temporary signs (banners, feather flags) use a separate Temporary Sign Permit Application under LUC Section 5.16.3. Despite a direct chase across the City's Fee Schedules page, the Zoning Permits webpage, and both Sign Permit Application PDFs, no published dollar fee figure for the sign permit itself could be located — flagged honestly below rather than estimated.

Fire Sprinkler and Fire Alarm System Permit
VerifiedIssued entirely by Poudre Fire Authority (PFA) — a joint city-district fire authority genuinely separate from Fort Collins Building Services — through its Fire Prevention and Community Risk Reduction (FPCRR) Division. Required for new or altered fire sprinkler systems (NFPA 13/13R commercial and multi-family, NFPA 13D one- and two-family dwellings), fire alarm systems, and related life-safety systems, governed by the City of Fort Collins' adopted 2024 International Fire Code (confirmed directly via PFA's own Fire Code Amendments page this session). Fees are calculated from system valuation via PFA's own online System Plan Review Fee Calculator, confirmed directly this session by testing several valuations, plus City sales tax (1.925%) and Larimer County tax (0.4%). This PFA permit is required IN ADDITION TO any City of Fort Collins Building Services permit for the same project.

- PFA reviews development documents and building-permit submittals for four jurisdictions sharing its 230-square-mile service area: the City of Fort Collins, Town of Timnath, Poudre Valley Fire Protection District, and unincorporated portions of Larimer and Weld Counties
- Fees are calculated via PFA's own online System Plan Review Fee Calculator based on the contractor-reported system valuation, and are paid separately from any City of Fort Collins Building Services permit fee for the same project

Change of Use / Change of Occupancy
VerifiedFort Collins has no standalone change-of-use or change-of-occupancy permit or fee line — confirmed directly this session by checking the Building Permits page's full list of permit-type accordions (52 entries, none named Change of Use or Change of Occupancy) and the Fee Schedules page's Zoning Services table (no such line item). A change of use/occupancy instead runs on two parallel tracks already partly documented elsewhere in this file: the zoning side, verifying the new use is allowed under the Table of Primary Uses in Article 4 of the Land Use Code for the property's zone district (optionally confirmed via a $100 Zoning Verification Letter); and the building-code side, where the existing Commercial Remodels permit type explicitly lists 'change of function, use, or occupancy' as an example project and requires the City's dedicated 'Change of Occupancy Permit Requirements' submittal packet, reviewed under the City's adopted 2024 International Existing Building Code (IEBC).

Requirements
- No standalone change-of-use or change-of-occupancy permit, application, or fee exists — confirmed absent from the Building Permits page's full set of permit-type accordions and from the Fee Schedules page's Zoning Services table, both checked directly this session
- Zoning-side check: the proposed new use must be allowed under the Table of Primary Uses in Article 4 of the Fort Collins Land Use Code for the property's zone district; a $100 Zoning Verification Letter (Development Review Fees, Zoning Services table) can be requested to confirm this before applying for a building permit
- If the new use is not a permitted or limited-permitted use in the applicable zone district, an Addition of Permitted Use process (a Development Review application, not itself a permit type documented in this file) may be required before a building permit can be issued
- Building-code side: a change of function, use, or occupancy is processed under the Commercial Remodels permit type (documented elsewhere in this file), using the same tiered valuation-based fee table, and additionally requires the City's 'Change of Occupancy Permit Requirements' submittal packet
- Reviewed against the City's adopted 2024 International Existing Building Code (IEBC) with Fort Collins Amendments (already listed in this file's codesAdopted), which governs the life-safety and accessibility compliance triggered by a change in occupancy classification
- Accessibility upgrades may be required depending on the specific occupancy change, per the City's Accessibility Upgrades Information guidance (already referenced under the Commercial Remodels entry)
- Construction Waste and Recycling Declaration of Responsibility + Report and an Owner Authorization Form (commercial/multifamily) are required as part of the underlying Commercial Remodel submittal
- Contact Building Services (buildingservices@fortcollins.gov, 970-416-2740) or Zoning (zoning@fortcollins.gov, 970-416-2745) directly to confirm which track(s) apply to a specific proposed use change, since no single consolidated City page walks through this exact scenario end-to-end
Required documents
- OptionalZoning Verification Letter ApplicationOptional pre-application check confirming the proposed use is allowed in the property's zone district under Article 4's Table of Primary Uses
