Permit cheat-sheet (Rhode Island rules)
| Project | Permit? | Authority | Typical fee | Timeline | Go / No-Go | Key notes |
|---|---|---|---|---|---|---|
| 🏠 Accessory Dwelling Unit (ADU) | Permit required | city | Rhode Island statewide valuation-based fee formula (Providence minimum permit fee $125). | Plan review; timeline varies by city (Providence 5–15 business days for most reviews). | Generally allowed | Rhode Island’s statewide ADU law requires every municipality to allow accessory dwelling units by right in single-family and two-family zones, so ADUs are broadly permitted. Local zoning still sets size, setbacks, parking, and owner-occupancy rules — verify with your city. Exempt: Rhode Island requires municipalities to allow ADUs by right in single- and two-family zones; size/number set locally. |
| 🪵 Deck / Porch | Conditional | city | Rhode Island statewide valuation-based fee formula (Providence minimum permit fee $125). | Over-the-counter for low decks; plan review for elevated decks (Providence ~3 weeks for decks >200 sq ft). | Generally allowed | Coastal/glacial soils and a 42 in frost depth mean deck footings must be inspected for depth. Exempt: Decks ≤30 in above adjacent grade are exempt (RI follows IRC R105.2). |
| 🧱 Fence / Wall | Conditional | city | Often no building permit under the height threshold; permit fee only if over threshold (statewide formula, $125 min). | Over-the-counter / zoning review for tall fences. | Generally allowed | Pool-barrier fences must meet barrier requirements. Posts typically set to the local frost depth (~36–42 in). Exempt: Fences not over 6 ft high are exempt (statewide). Providence front-yard fences limited to 4 ft. |
| 🛖 Shed / Outbuilding | Conditional | city | Valuation-based when over the exemption size (statewide formula, $125 min). | Small exempt sheds need no permit; permitted sheds go through plan review. | Generally allowed | The 64 sq ft exemption is a key Rhode Island quirk — far smaller than most states. Footings must reach below the ~42 in frost line. Exempt: IMPORTANT: Rhode Island amended R105.2 — only one-story detached accessory structures ≤64 sq ft are exempt (smaller than the base IRC’s 120 sq ft). |
| 🪜 Basement Finish | Permit required | city | Valuation-based; includes trade permits (statewide formula, $125 min). | Standard plan review 2–4 weeks. | Generally allowed | Creating living space triggers framing, electrical, insulation, and egress-window requirements under the RI Dwelling Code. Exempt: Cosmetic finishing (paint, flooring) is exempt. |
| 🚗 Garage / Carport | Permit required | city | Valuation-based; includes trade permits (statewide formula, $125 min). | New-structure plan review; varies by city. | Generally allowed | Attached and detached garages require a full building permit and plan review; footings below frost depth. Exempt: All garages over the 64 sq ft exemption require a permit. |
| ☀️ Rooftop Solar PV | Permit required | city | Building + electrical permits (statewide formula, $125 min). | Rooftop PV review typically quick once structural/electrical docs are submitted. | Generally allowed | Rhode Island’s energy code and structural requirements apply; coastal wind loads are reviewed. Exempt: No size exemption; rooftop PV requires building and electrical permits. |
| 🌡️ HVAC Replacement | Conditional | city | Mechanical permit; fee set per the statewide formula ($125 min). | Trade permits often issued same-day/over-the-counter for in-kind replacements. | Generally allowed | Rhode Island’s energy code is strict (2024 IECC with RI amendments); equipment must meet efficiency rules. Exempt: Portable heating/cooling/evaporative units are exempt; installed HVAC needs a mechanical permit. |
| 🍳 Kitchen Remodel | Conditional | city | Valuation-based when structural/plumbing/electrical work is included (statewide formula, $125 min). | Standard review for permitted scopes. | Generally allowed | Renovations in older homes can trigger energy-code upgrade requirements for the space. Exempt: Cabinet/countertop swap in the same layout is exempt (cosmetic finish work). |
| 🛁 Bathroom Remodel | Conditional | city | Valuation-based when plumbing is relocated (statewide formula, $125 min). | Standard review for permitted scopes. | Generally allowed | Ventilation to the exterior required; plumbing under the Rhode Island State Plumbing Code. Exempt: Fixture-for-fixture swap in place is often exempt. |
| 🏗️ Room Addition | Permit required | city | Valuation-based; includes trade permits and impact fees (statewide formula, $125 min). | Plan review several weeks (Providence 5–15 business days for most reviews). | Generally allowed | Energy-code upgrades for the new space are reviewed under the 2024 IECC with RI amendments. Exempt: No exemption — any new conditioned footprint requires a permit. |
| 🪟 Window / Door Replacement | Conditional | city | Usually no fee for sash-only swap; permit needed for full frame-and-sash replacement or enlarged openings. | In-kind swaps typically need no review. | Generally allowed | Replacement products must meet RI energy-code (2024 IECC with RI amendments) U-factor when the code is triggered. Exempt: Replacement window sash installations are exempt; full frame-and-sash replacements require a permit. |
| 🏘️ Roof Replacement | Conditional | city | Often over-the-counter or exempt for same-footprint re-roof; otherwise valuation-based (statewide formula, $125 min). | Re-roof often processed quickly. | Generally allowed | Coastal wind and ice-damming requirements apply; some municipalities require a permit for full tear-offs. Exempt: Rhode Island’s amended R105.2 does NOT explicitly list re-roofing as exempt — verification with the local building department is required. |
| 🅿️ Driveway / Parking Pad | Conditional | city | Building permit often not required under the exemption; curb-cut/right-of-way work is separate. | Right-of-way permits reviewed by the city/public works. | Generally allowed | A separate right-of-way permit is usually needed to cut the curb or connect to the street. Exempt: Sidewalks/driveways not >30 in above grade and not over a basement are exempt (statewide). |
| 🏊 Swimming Pool / Spa | Permit required | city | Valuation-based; includes barrier/fencing and electrical bonding review (statewide formula, $125 min). | Plan review several weeks; barrier inspection required before filling. | Generally allowed | Rhode Island pool-barrier rules apply; electrical bonding under the RI State Electrical Code. Exempt: Prefabricated pools <24 in deep are exempt from a building permit; permanent/in-ground pools always permitted. |
| 🧱 Retaining Wall | Conditional | city | Valuation-based when over the height threshold (statewide formula, $125 min). | Over-threshold walls need plan review (engineering for surcharge). | Generally allowed | Rhode Island’s threshold (32 in) and the cast-in-place concrete carve-out (24 in) differ from the base IRC (4 ft) — a key state-specific rule. Exempt: Rhode Island exempts retaining walls ≤32 in (measured from lower finished grade to top), unless supporting a surcharge. |
| 💥 Demolition / Teardown | Permit required | city | Demolition permit fee set by the issuing authority; verify locally. | — | Generally allowed | A full teardown or major strip-out requires a demolition (building) permit. Demolition permits commonly require proof of utility disconnects (water, gas, electric, sewer) and may require asbestos/lead-paint clearance for pre-1978 homes before work begins. Verify the issuing authority for your specific property. |
| 🚰 Septic System | Permit required | state | Septic/OWTS permit fee set by Rhode Island DEM; based on system type. | — | Generally allowed | New or replacement onsite wastewater (septic) systems require a permit from the Rhode Island Department of Environmental Management (DEM) Onsite Wastewater Treatment System (OWTS) Program. A soil evaluation and engineered design are required; DEM-licensed designers and installers perform the work and DEM inspects during installation before backfill, issuing a Certificate of Conformance. |
