  • airport-noise-zone — NAVSTA Newport AICUZ (Air Installation Compatible Use Zones) cover the entire base; DNL 65+ contours extend off-base into adjacent civilian Newport neighborhoods
    Applicable: false - federal military installation under NAVFAC jurisdiction. AICUZ is a federal planning overlay applicable within the base fence line. AICUZ influence on surrounding civilian parcels is captured on the Newport city-level research.
  • historic-district — Naval War College (Coasters Harbor Island) is a National Historic Landmark District; Naval Hospital Newport is listed on the NRHP
    Applicable: false - federal military installation under NAVFAC jurisdiction. NHPA Section 106 review applies to federal undertakings on base, but this is a federal SHPO/NAVFAC process, not Newport HDC.
  • flood-zone — Shoreline portions of NAVSTA Newport fall in FEMA AE and VE zones along Narragansett Bay and Coddington Cove
    Applicable: false - federal military installation under NAVFAC jurisdiction. NAVFAC uses UFC 3-201-01 flood criteria rather than FEMA NFIP permitting.
  • wetland-overlay — Coddington Cove and Narragansett Bay tidal wetlands border base parcels
    Applicable: false - federal military installation under NAVFAC jurisdiction. Federal wetlands on DoD lands are managed under CWA Section 404 federal process, not CRMC.

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.

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.
