Fee schedule
Assessed on project valuation per Draper's building permit fee schedule: Draper Consolidated Fee Schedule, Resolution 26-29 (Jul 2026), item 44. Show full citationHide
Assessed on project valuation per Draper's building permit fee schedule: Draper Consolidated Fee Schedule, Resolution 26-29 (Jul 2026), item 44. Resolution 26-29 supersedes Resolution 25-52 (Oct 2025), whose PDF no longer resolves at the media URL; the fee figures are identical between the two editions. Draper's ADU Permit — a planning/compliance permit required under Resolution 21-47, separate from the construction building permit — has no published flat fee in the Consolidated Fee Schedule; no Building Permit or Planning fee line item references an ADU. Construction work to create or modify an ADU (basement finish, addition, garage conversion, detached structure) is billed as the standard valuation-based Building Permit. This is the only ADU-related fee Draper publishes.Review timeline

Tips
- Draper has a dedicated ADU Permits page — confirm ADU eligibility and Draper-specific regulations at draperutah.gov/business-development/planning-and-development/accessory-dwelling-units-permits/ before applying.
- As of October 1, 2021, Draper requires a separate ADU Permit (Resolution 21-47) verifying zoning/regulatory compliance — distinct from the construction Building Permit. Draper allows one Internal ADU (I-ADU, e.g. basement apartment) or one Detached ADU (D-ADU) per single-family lot, not both; the primary dwelling must be owner-occupied, and the unit must be rented for 30+ consecutive days. Owner-builder
- Utah state law (HB 82, 2021) requires cities to allow at least internal ADUs; Draper also allows detached ADUs on lots 12,000+ sq ft (I-ADUs generally require 6,000+ sq ft and street-width compliance — verify via Draper's interactive eligibility map).
- Basement apartments in Draper must have egress windows in every bedroom (5.7 sq ft minimum opening).
- Draper's Consolidated Fee Schedule does not publish a separate flat fee for the ADU (compliance) permit itself — only the construction Building Permit fee (ICC valuation-based) applies; confirm with the Planning Office at (801) 576-6399 if a distinct administrative fee is assessed at intake.
