What Are Colorado Impact Fees?
Colorado local governments impose development impact fees under C.R.S. § 29-20-104.5, which requires fees to be legislatively adopted, quantified, and no greater than necessary to defray the impacts directly related to new development. Water is the defining cost driver: many Front Range providers charge substantial water resource and tap fees on top of land-use impact fees for streets, parks, police, and fire.
A single-family permit along the Front Range can carry tens of thousands of dollars in combined fees, while rural and Western Slope jurisdictions charge far less. Colorado figures on impactfees.org are model estimates calibrated to statewide cost factors and community size — ideal for comparing metros before confirming adopted schedules with each city, county, or water district.
Colorado figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
