Accessory Dwelling Unit (ADU) Permit
VerifiedThe City of Riverton has NO dedicated Accessory Dwelling Unit ordinance, definition, or permit category in its Zoning Code (Title 17, ecode360, chapters 17.04 through 17.88 reviewed in full). 'Accessory building/use' in Riverton's code means a subordinate NON-DWELLING structure (shed, garage, storage building) — not a secondary living unit. The closest legal pathway to a second housing unit on one lot is the R-2 Residential District, which permits 'multiple-family dwellings containing not more than two living units' (RMC § 17.32.010.A) as a true duplex — each unit independently meeting the district's own minimum floor area (425 sq ft per unit) — built and permitted as standard new residential construction, not as an accessory/ADU pathway.
