What is Renton's PRADU program actually worth?
✓ Verified against code · August 19, 2026
Roughly eight free pre-engineered DADU plans, permits that can issue in about a week, waived plan-review/application fees, several impact fees waived and others reduced — the city estimates around $40,000 in savings. The waiver terms live in the city's fee schedule rather than the municipal code, so confirm current terms with Renton CED before budgeting.
