DEPENDS ON LOCATION
Rhode Island — Real 2024 law, but the by-right guarantee is narrower than headlines suggest (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law; the state's small size and dense towns make wheeled primary residences uncommon.
ADU / accessory unitThis sharpens an earlier hedged draft. Rhode Island's ADU statute (R.I. Gen. Laws §45-24-73, most recently amended by 2024 legislation signed by Gov. McKee) guarantees one ADU by right only under three specific circumstances: (1) on an owner-occupied property as a reasonable accommodation for a family member with a disability, (2) on a lot of 20,000 sq ft or more with a residential primary use, or (3) where the ADU sits within the existing footprint of the primary or an existing accessory structure. Outside those three circumstances, a municipality's standard zoning process (which may include a special-use permit) still applies.
Minimum square footageWhere the by-right guarantee applies, municipalities must allow at least 900 sq ft (or 60% of the primary home) for a one-bedroom ADU, and 1,200 sq ft (or 60%) for a two-bedroom
Foundation requirementFoundation-built ADUs have the clearest path within the three by-right circumstances; anything outside them defaults to local review
Local notesDon't assume 'Rhode Island legalized ADUs statewide' means every possible ADU is by-right — check whether your specific situation matches one of the three qualifying circumstances before assuming no permit process applies.
!Zoning is set by your specific city or county, not the state as a whole. Use this as a starting point, then confirm with the local building or planning department before you buy land or start a build. Not legal advice.
