Questions
Does Colorado charge impact fees on a new home?
Colorado counties may charge impact fees on new development under C.R.S. 29-20-104.5; the county fees here are road (traffic) and county-facility fees. Whether a home pays, and how much, depends on the county, city or utility; the table lists each schedule Groundwork has checked.
Which Colorado jurisdiction in the table charges the most?
Of the 3 impact fee schedules in force on Nov 10, 2026, Jefferson County is highest, at up to $5,489 for one new single-family home; source: Jefferson County Policy Manual: Traffic Impact Fee Program Policy (Resolution CC23-063, effective January 1, 2025).
Do I pay these fees when I buy vacant land?
No. They are due while a new home is built: at the building permit in most places, before the certificate of occupancy in some, and a utility fee when the home connects to water and sewer. They belong in the cost of building, not the land price.
Does a county missing from the table charge nothing?
Not necessarily. A county or city that is not listed has not been checked yet; ask its building or planning department.
