Denver ADU Permit Fees & Cost Calculator
Denver allows ADUs citywide, but the exact city fee schedule for ADU permits, plan review, utility taps, and any school-related charges was not clearly available in the provided official sources, so the fee items below are marked for verification. The most reliable official source here confirms the citywide ADU zoning change, while Colorado guidance notes that local ADU fee programs may involve permit, impact, school district, and utility fees.[10][7]

Step 1 of 5: Location
The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
The search results include secondary sources with estimated fee ranges, but those were not used as exact fee amounts because the prompt says not to invent exact fees.
Denver's zoning rules changed in late 2024 to allow ADUs citywide, but that does not by itself establish the fee amounts.
Any final fee estimate should be confirmed against current Denver permit tables and the applicable utility and school district schedules.
The user wants fee data for an ADU, not the cost of construction or financing.
Because no official Denver fee schedule was provided in the search results, numeric fee amounts are left null.
Denver Public Schools, Denver Water, and other outside agencies may have separate fees that must be verified directly from their official schedules.
FAQs
Are Denver ADU fee estimates official?
No. ADUFee.com provides planning estimates only. Final fees are set by the city, utility providers, school district, and other agencies.
What sources are used for Denver?
The database stores city, state, utility, school, county, and other source links where available. Each estimate should still be verified locally.
Can ADU fees vary within Colorado?
Yes. Permit, utility, school, inspection, and impact fees can vary by jurisdiction, parcel, project size, utility provider, and local interpretation.
