Fee breakdown (as of 2026-04)
Permitting process
- Confirm parcel zoning and ADU eligibility under Lincoln Chapter 260 (~3d)
Verify the parcel is in an R-zone where ADUs are permitted by-right under the post-Ord. 2023-12 use table. Check whether parcel falls within the Great Road National Historic District (which adds Historic District Commission review) or a FEMA SFHA along the Blackstone River corridor. - Pre-application conversation with Lincoln Building Official (~5d)
Russell Hervieux (rhervieux@lincolnri.org / 401-333-8430) at 100 Old River Road can confirm setback/coverage interpretation under Chapter 260 and flag whether the proposed ADU triggers any historic-district or Twin River casino-area overlay review. - Submit building permit via RI statewide e-permitting (permits.ri.gov) (~1d)
Lincoln onboarded the RIBCC statewide e-permitting portal on 2017-10-23; paper applications are not accepted. Upload IRC plans, site plan showing setbacks/coverage, and septic/well documentation if applicable. - Building plan review against IRC 2018 with RI amendments (~14d)
Plans reviewed for IRC 2018 compliance with RI state amendments including the deletion of R313 residential sprinkler mandate, so detached ADUs do not need NFPA 13D. MEP disciplines reviewed in parallel by Lincoln Building Department. - Lincoln Water Commission service review (96 Old River Road) (~10d)
The Lincoln Water Commission (NOT Pawtucket Water Supply Board) is the franchised water utility for Lincoln including Saylesville, Lonsdale, and Manville. Verify lateral capacity for ADU bedroom add (Manville Tank serves the village area). Separate meter not required for attached ADU; detached ADU may benefit from one for sub-metering. - Narragansett Bay Commission (Bucklin Point) sewer coordination (~7d)
Lincoln wastewater feeds the Bucklin Point treatment facility operated by Narragansett Bay Commission; impact-fee verification required for ADU bedroom add. Some Lincoln parcels remain on private septic and require RIDEM ISDS review. - Pay state-formula fees plus Lincoln local surcharges (~1d)
Fees per RI 510-RICR-00-00-21 (~$19-23 per $1,000 valuation) plus the state-mandated levy under RIGL 23-27.3-108.2(c)(1) and Lincoln's $30 zoning certificate at issuance. - Six-stage construction inspections (footing, foundation, framing, MEP rough, insulation, final)
Scheduled via Lincoln Building Department (401-333-8430). Lincoln Fire coordinates fire-marshal inspections. No sprinkler inspection needed for IRC-built detached ADU under RI amendments. - Certificate of Occupancy issued by Lincoln Building Official (~5d)
$75 CO fee; CO triggers tax-assessor parcel update and Lincoln Water Commission separate-meter activation if requested.

Legal history (timeline)
Current ordinance: Town of Lincoln Zoning Ordinance Chapter 260 (as amended by Ord. 2023-12, conformed to RIGL 45-24-73), adopted 1948-06-14, last amended 2023-11-08
- 2023-11-08 — Lincoln Town Council adopts Ord. 2023-12 - Zoning Use Regulations Amendment (Chapter 260) (city-ordinance)
Lincoln amended Chapter 260 use-regulations table to add ADU as a permitted use in residential zones, in anticipation of and conformance with the pending statewide preemption.
Effect: Removed the prior 'accessory family dwelling unit' framework that required annual occupancy letters and special-use-permit recordation; ADUs are now ministerial in Lincoln's R-zones. - 2024-06-25 — RI H 7062 / S 2998 enacted (P.L. 2024 ch. 284-287) - statewide ADU preemption (RIGL 45-24-37(j), 45-24-73) (state-law)
Made ADUs a permitted use in all residential zones statewide via administrative building-permit-only process; established minimum size floors (900 sqft studio/1BR, 1200 sqft 2BR or 60% of primary, whichever is less); voided HOA ADU prohibitions.
Effect: Lincoln's remaining ADU-restrictive language in Chapter 260 (size cap, owner-occupancy, family-only) is preempted; only the dimensional, parking, and design-standard provisions consistent with the statute remain enforceable.
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.
