Permitting process
- Confirm Riverside village address falls within East Providence city zoning jurisdiction (~1d)
Riverside is one of the four villages of East Providence (zip 02915), south of Wampanoag Trail; permitting is handled by the East Providence Building Inspection Division at City Hall (145 Taunton Avenue, 2nd floor) - NOT by any Riverside municipal office (no such office exists) - Pre-submittal zoning check vs. East Providence Code Chapter 19 Sec. 19-202 (~5d)
Per Sec. 19-202 (ADU section) and Sec. 19-1 (definitions): one ADU per single-family residential lot; 5,000 sq ft lot minimum (city reduced from state's 20,000 sq ft default per Sept 2 2025 Council vote); ADU may be internal, attached, or detached; STR (Airbnb) PROHIBITED; family-member-disability accommodation gets no-minimum-lot exemption - Crescent Park / Bullocks Cove coastal & historic overlay screening (~75d)
Riverside parcels along Bullocks Cove and the Narragansett Bay shoreline (Pomham Light, Sabin Point, Riverside Drive corridor) lie within CRMC's 200-foot Coastal Zone; the Crescent Park Looff Carousel National Historic Landmark area parcels add HDC review. Coastal-zone ADUs need CRMC Assent (60-90 days) - Plan submittal via East Providence Viewpoint Cloud online portal (~3d)
East Providence uses Viewpoint Cloud (https://eastprovidenceri.viewpointcloud.com/) for online permit submittal - the only one of the five RI cities researched to use a modern eGov platform. In-person submittal also accepted at City Hall, 145 Taunton Avenue, 2nd floor, during posted hours (Mon-Wed 8-4, Thu 8-6, Fri 8-1) - Administrative ADU permit review by Building Official Robert M. Walker Jr. (~25d)
Per RIGL 45-24-37(j) state preemption AND East Providence Sec. 19-202 (adopted unanimously by EP Council Sept 2 2025): code-compliant ADUs are administrative-permit only - no Zoning Board hearing. Walker's office reviews building/structural; EP Planning Department reviews zoning compliance - East Providence Water Division + Narragansett Bay Commission tap availability (~14d)
Riverside is on full municipal water (EP Water Division) and sewer (NBC); confirm tap availability. Older Riverside parcels south of Bullocks Point sometimes still on private septic - those need RIDEM ISDS approval (~30 days) - Pay East Providence permit fee (RI statewide formula 510-RICR-00-00-21) (~2d)
EP rate: $15/$1k for first $10k, $150+$13/$1k for $10-50k, $670+$11/$1k over $50k; minimum $85 (East Providence rates were updated by Building Code Standards Committee Jan 2022). For a $200k ADU the permit fee is $2,320 - Construction inspections by EP Building Inspection Division
Foundation, framing, rough MEP, insulation, final; East Providence Fire Department handles fire-marshal-level reviews (single department, not separate fire districts). Riverside's older Crescent Park / Pomham Heights pre-1978 stock often triggers lead-paint disclosure for conversion ADUs - Certificate of Occupancy issued by EP Building Inspection Division (~7d)
Final CofO triggers EP Tax Assessor parcel update and EP Water Division account creation if separately metered. CRMC final sign-off required for coastal-zone parcels (Bullocks Cove, Narragansett Bay shoreline)

HOA prevalence & 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.

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.
