Rhode Island enacted statewide ADU preemption in 2024 through H 7062 (chief sponsor Rep. June Speakman and colleagues; co-sponsored in the Senate as S 2710), which amended the Zoning Enabling Act (Title 45, Chapter 24). Municipalities must permit ADUs by-right on any lot containing a single-family dwelling, subject only to uniform minimum standards set by the statute. One of the most ADU-friendly state statutes in the country as of 2025.

• R.I.G.L. § 45-24-73 — Design standards required for accessory dwelling units; Consistent statewide treatment of accessory dwelling units required — Core ADU standards added by H 7062 (2024). Requires municipalities to permit ADUs by-right. Caps 1-bedroom and studio ADUs at 900 sqft or 60% of the principal dwelling's floor area, whichever is less. Caps 2-bedroom ADUs at 1,200 sqft or 60%, whichever is less. Prohibits owner-occupancy requirements. Caps additional parking at 1 off-street space per bedroom. Prohibits ADU-specific impact fees. Voids HOA, condominium, and similar private-covenant restrictions that conflict with the statute as against public policy.
• H 7062 (2024 RI General Assembly) — An Act Relating to Housing — Accessory Dwelling Units — The enacting bill. Also cited by municipalities adopting conforming ordinances (Providence 2024 Chapter 3584, East Providence 2024 ADU Ordinance, South Kingstown 2024-07-12 regulations).

R.I.G.L. § 45-24-73 explicitly voids homeowners' association, condominium association, or similar private-covenant restrictions on ADUs when those restrictions conflict with the statute's ADU minimums. The preemption is framed as a public-policy void, meaning the offending covenant is unenforceable rather than simply regulated. Pre-existing ADU-friendly covenants remain valid (the statute only void conflicting restrictions). Applies to all common-interest communities governed by the Rhode Island Condominium Act (R.I.G.L. Title 34, Chapter 36) and Rhode Island Condominium Ownership Act (Title 34, Chapter 36.1), as well as HOAs in planned-community subdivisions.

• R.I.G.L. § 45-24-73 (HOA preemption clause added by H 7062 (2024)) — Provides that private covenant restrictions imposed by condominium associations, homeowners' associations, or similar residential property governing bodies that conflict with the ADU provisions are void as against public policy. Drafted broadly — covers declarations, bylaws, rules and regulations, and recorded covenants.

RIHousing, the state's housing finance agency, operates an ADU financing program built around the FHA 203(k) loan product. Covers attached and interior ADUs for both purchase and refinance. Detached ADUs are NOT eligible. Requires mandatory homebuyer education, use of an FHA-approved 203(k) consultant, and a RI licensed and insured contractor. No state-specific grant program for ADUs is in effect as of 2026-04-21; the federal 203(k) rails are the production vehicle.

Rhode Island does not currently operate a single statewide pre-approved-ADU-plan catalog (as California's CalHFA and Washington's Commerce plan libraries). Implementation of the 2024 ADU law is happening municipality-by-municipality, with the Executive Office of Housing (EOH) coordinating technical assistance. Providence published a citywide ADU Guide (February 2025) as the leading model; East Providence adopted a conforming ordinance in 2024; South Kingstown published regulations in 2024. RIHousing runs the ADU financing side (see stateFinancing).
