Transportation Capital Expansion Fee (TCEF)

New Transportation Capital Expansion Fees (TCEFs) Effective October 1, 2026

The new TCEFs are in effect as of October 1, 2026.

The Transportation Capital Expansion Fee (TCEF) is a one-time fee that may apply to certain development in unincorporated Larimer County.

Why is TCEF needed?

New development can increase demand on the transportation system. TCEF helps provide funding for transportation improvements associated with that growth.

How are fees determined?

TCEF rates are based on the type and size of development and its transportation impacts. Fees are periodically reviewed and updated based on changes in development, transportation needs, and costs.

Legal Authority

Larimer County is authorized to collect Transportation Capital Expansion Fees (TCEF) under Colorado Revised Statutes Section 29-20-104.5. Locally, the fee program is governed by the County TCEF Study and regulated through the Larimer County Land Use Code,  Articles 15.1.6 and 15.1.7.

When is TCEF collected?

The fee is typically collected when a building permit is issued or before a new use begins.

Fees are reviewed annually and may increase each July 1 under Article 15 of the Land Use Code.
