ADU legality: allowed-with-restrictions
East Greenwich's family/age-62/disability framing predates H 7062 and has not been fully aligned with the by-right state mandate as of 2026-04. Whether the local 'reasonable accommodation' framing survives a state preemption challenge is untested. Applicants outside the family/age/disability framing should consult the Planning Department before filing.

Permitting process
Viability (permitted uses)
- Long-term rental: with-restrictions Long-term rental only to family members meeting the disability or age-62+ criterion. Standard market-rate long-term rental is NOT contemplated by the local ordinance and would conflict with the family-occupancy framing — requires preemption argument under H 7062.
- Short-term rental: no East Greenwich's § 260-9(C) frames ADUs as 'reasonable accommodation' for family members with disabilities or 62+. STR use is incompatible with the family-occupancy criterion.
- Office rental: no ADU classification is residential dwelling for family member; commercial office rental is not a permitted use.
- Home office: yes Standard home occupation use within the principal dwelling is permitted under Chapter 260.
- Studio / workshop: with-restrictions Owner-use studio inside the ADU is fine subject to the family-occupancy framing; standalone studio rental is prohibited.
- Agriculture: with-restrictions Limited urban agriculture permitted in residential districts per Chapter 260.
- Relative support: yes Family-occupancy ADU for relatives with disabilities or aged 62+ is the primary permitted ADU use under § 260-9(C). This is the dominant East Greenwich ADU configuration.

Known issues (2)
- policy-review — East Greenwich's § 260-9(C) family-occupancy framing has not been amended to fully match the H 7062 by-right baseline. Applicants seeking standard market-rate rental ADU should expect to litigate the preemption argument; family-occupancy applicants face no such friction. Confirm pathway with Planning Department before designing.
- policy-review — 20-foot detached ADU height cap is among the most restrictive in Rhode Island and effectively rules out two-story compact designs popular in modular ADU catalogs.
Rhode Island state — ADU law and programs
State ADU law
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).
State HOA preemption
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.
State financing programs
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.
State housing programs
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).
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
