Fee schedule

Building Permit — valuation-basedAssessed on project valuation per Draper's building permit fee schedule, cited: Draper Consolidated Fee Schedule, Resolution 26-29 (Jul 2026), item 44 — re-fetched and confirmed live 2026-07-13. 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 (searched all Building Permit and Planning fee line-items — none reference ADU); construction work to create/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. Prior citation (Resolution 25-52, Oct 2025 PDF) went dead (404); superseded by Resolution 26-29 (Jul 2026) at the same media URL with identical fee figures.

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.
