When you need this permit
- Complete a Town of Timnath Building Permit Application, checking 'Tenant Finish' as the project type; describe the proposed use, business name/product, type of construction, dimensions, square footage, and materials, and note the use of surrounding spaces
- Applicant/general contractor must hold a current Town of Timnath Contractor License for CommunityCore submittal access Contractor
- Submit an electronic set of stamped plans per SAFEbuilt Colorado's Commercial Tenant Finish/Remodel Plan Submittal Procedure: Architectural Plans (floor plan, wall section details, building section, fire-rating details, code summary), Structural Plans (required for any structural changes such as removal of bearing walls, openings in bearing walls, or floor systems for storage), Electrical Plans (required for adding circuits, service upgrades, or emergency lighting — load calculations, one-line diagrams, fault current analysis), Mechanical/Plumbing Plans (required for HVAC equipment changes or ductwork/refrigeration piping relocation, and for any changes to sewers, drains, vents, water piping, roof drains, or gas piping), and Energy Code Compliance Documents — all sheets must bear the original seal of a Colorado-licensed architect or engineer per C.R.S. (exemptions under section 12-4-112 C.R.S. apply to specific sub-disciplines)
- Restaurant/commercial-kitchen tenant finishes carry the same additional design requirements as new commercial construction: grease interceptor sizing, fire sprinkler system if over 5,000 SF or 50+ occupants, Type I/II hoods, health department (Larimer County) approval as a CO condition, seating plan, and panic hardware for 50+ occupant loads
- If the underlying shell was permitted as Core & Shell, the Police, Public Buildings, and Transportation Capital Improvement Impact Fees (assessed per 1,000 SF of non-residential building) become due and payable at tenant-finish permit issuance rather than at Core & Shell issuance, per Ordinance No. 5, Series 2024, Sec. 4-6-50(a)(1)/(c)(1)/(e)(1)
- Site Grading Certification is NOT listed as a tenant-finish trigger in the Town's Building Permit Application notice — it is required only for new Single/Two/Multi-Family Residences, new Commercial/Industrial structures, and additions to existing Commercial/Industrial structures

Tips
- Timnath's Building Permit Application distinguishes 'Tenant Finish' from 'Commercial' (new/Core & Shell) — make sure the correct checkbox is used, since the submittal procedure and impact-fee timing differ between the two.
- If the shell building was permitted as Core & Shell, budget for the Police/Public Buildings/Transportation impact fees to land at tenant-finish issuance rather than assuming they were already paid — confirm the shell permit's fee-payment status with Building Services before budgeting.
- A restaurant or commercial-kitchen tenant finish carries the same grease-interceptor, hood, sprinkler, and health-department requirements as new commercial construction — plan for these even on an interior-only remodel.
- Site Grading Certification is not listed as a tenant-finish trigger — don't budget time/cost for it unless your scope also includes an addition to the structure.
- No published SLA exists for tenant-finish review time, but a real Town of Timnath economic-incentive letter (civicweb document 110110, dated 3/14/2024) documents an actual $500,000 commercial tenant-finish project (Zzap Health, a health/wellness center build-out with new fire suppression and ADA work) that ran from permit application (6/30/2023) to permit issuance (9/26/2023) in about 88 calendar days — useful as a rough real-world data point, though it is one project's outcome, not a guaranteed turnaround, and may reflect project-specific revision cycles.
