Accessory Dwelling Unit (ADU) Permit
VerifiedGreen River's zoning ordinance (Code of Ordinances Appendix B, Chapter 9 — Use Regulations) has NO dedicated Accessory Dwelling Unit (ADU) permit type or zoning category. The zoning code's own definition of 'Accessory Buildings, Structures and Uses' (Section 9.6) explicitly excludes residential occupancy: an accessory use 'Does not include residential occupancy.' A second dwelling unit on a lot must instead be built as a recognized 'Multi-Unit Dwelling' use (permitted only in specific multi-family zoning districts, e.g. R-3/R-4), not as an accessory structure to a single-family home.
Verified 2026-07-01 · Source
Requirements
- No ADU-specific permit or zoning pathway exists in Green River; do not apply expecting an 'ADU' permit type
- An accessory structure (garage, shed, workshop) may NOT include residential occupancy per Zoning Code Section 9.6.A ('Accessory Buildings, Structures and Uses') and the Shed & Accessory Structure Brochure
- A genuine second dwelling unit on a property requires the lot to be zoned for Multi-Unit Dwelling use (the zoning Table of Uses permits 'Multi-Unit Dwelling' only in specific districts, e.g. R-3/R-4, not R-1/R-2 single-family districts) — this is processed as a standard residential building permit for a duplex/multi-family structure, not an ADU permit
- Confirm zoning district and permitted use eligibility with Development Services/Planning before attempting any second-unit project
