Rhode Island Boat Lift Permit: CRMC Rules by Water Type

Yes. In Rhode Island a boat lift on tidal water needs an Assent from the Coastal Resources Management Council (CRMC). The Red Book, the CRMC's main rule (650-RICR-20-00-1), lists "boat and float lifts" by name among the work it reviews. No size or season makes a lift exempt.

What decides the outcome is the water type painted on the CRMC's maps in front of your dock. Lifts "may be allowed in Type 3, 5, and 6 waters." In Type 2 water a lift is a harder Category B application, judged on scenery. In the Type 2 parts of 16 named waterbodies, and in all Type 1 water, a lift is banned. No engineering and no fee changes that.

The wrong answer you will hear is "the lift is just part of the dock, so the dock permit covers it." It persists because many Rhode Island docks were assented with a lift shown on the plans. But the Red Book treats a lift as its own accessory structure with its own rules, and the CRMC will not even weigh it when it decides the dock. A lift added later is a new filing. This is general information, not legal advice.

Who approves: the CRMC, under Red Book section 1.3.1(P), Boat Lift and Float Lift Systems
Allowed: Type 3, 5 and 6 waters
Type 2: Category B review, only "the minimum amount necessary," banned in 16 named waterbodies
Banned: all Type 1 waters, including at docks already permitted there
Limits: 2 boat lifts and 1 float lift per residential dock; 25 ft from extended property lines
Height: raised boat no higher than the pier deck, and hull bottom no more than 5 ft above high tide, whichever is lower
Plans: stamped by a professional engineer
Fees: $1,500 for a new dock; the schedule has no separate lift line

The terms the answer turns on

Boat lift and float lift. The Red Book defines "boat and float lift systems" as "accessory structures to residential boating facilities that raise either a boat or float out of the water." A boat lift is the familiar cradle or sling, often a four-post vertical lift. A float lift raises the dock's floating platform out of the water, usually with winches on the pilings. "Residential boating facility" is the rule's term for a private dock.

Assent. The CRMC's word for its permit. A Category A Assent is the routine kind, decided by staff when a project meets every standard. A Category B Assent needs a written environmental assessment and a 30-day public notice. If anyone files a substantive objection, it goes to a hearing.

Water type. The CRMC splits Rhode Island's tidal water into six types. Each one decides what may be built there. The Red Book says about 70 percent of the state's 420 miles of shoreline faces Type 1 or Type 2 water. So most waterfront homes sit on the two types where lifts are hardest.

Type 1, Conservation Areas: water by refuges, unusually scenic water, and water too exposed to waves for structures. Docks are "considered by the Council as unsuitable."
Type 2, Low Intensity Use: water "adjacent to predominantly residential areas, where docks are acceptable" but more intense uses are not.
Type 3, High Intensity Boating: water dominated by marinas and boatyards.
Type 4, Multipurpose Waters: the open waters of Narragansett Bay and the Sounds.
Type 5 and Type 6: commercial and recreational harbors, and industrial waterfronts and shipping channels.

Find your type on the CRMC's water type maps, drawn by town. Your engineer will also mark it on the plan.

Rhode Island lift rules by water type

Boat and float lifts at residential docks by CRMC water type (Red Book 650-RICR-20-00-1, sections 1.1.6 and 1.3.1(P), effective November 24, 2024)
Water type at the dock	Lift allowed?	How it is reviewed
Type 1	No, not even at a dock permitted there before	Prohibited
Type 2 in one of the 16 named waterbodies	No	Prohibited
Other Type 2 water	Only the "minimum amount necessary" for the dock	Category B; full Council if anyone objects
Type 3, 5 or 6	May be allowed	Reviewed under the dock policies in 1.3.1(D)
Type 4	Not named in 1.3.1(P) either way	Ask CRMC staff before you design

Where lifts are banned

Section 1.3.1(P)(3)(b) says lifts "are prohibited in Type 1 waters and in association with existing previously-permitted residential boating facilities in Type 1 waters." An old dock does not carry a right to add a lift.

The second ban is narrower. The CRMC found that lifts "detract from the high scenic value" of Type 2 water and may be "an unacceptable intensification of use." So lifts are banned in "all Type 2 waters" within these 16 waterbodies:

South County: Pawcatuck River, Winnapaug Pond, Quonochontaug Pond, Ninigret Pond, Green Hill Pond, Potter Pond, Point Judith Pond and the Narrow River
North Kingstown: Bissel Cove and Wickford Harbor
East Bay: Barrington River, Palmer River, Kickemuit River, Potter Cove, Bristol Harbor and Blue Bill Cove

The rule lists only the names, so the grouping by area here is a reading aid. The ban covers only the Type 2 parts. A stretch of Wickford Harbor or Bristol Harbor mapped as Type 3 falls under the Type 3 rules instead.

Outside Types 1 and 2, the rule is short. In Type 3, 5 and 6 water lifts "may be allowed," and section 1.3.1(P)(2)(b) sends those applications through "the Council's established policies" for docks in 1.3.1(D). Type 4, the open bay, is not named in 1.3.1(P) at all, neither allowed nor banned. If your dock faces Type 4 water, ask CRMC staff how they will treat a lift before you pay for design.

Type 2 water: allowed, but harder

Outside those 16 waterbodies, a lift may be allowed in Type 2 water. Three rules make it harder.

Category B. A Type 2 lift is always a Category B application (1.3.1(P)(2)(a)). That means an environmental assessment and a 30-day public notice.
Minimum necessary. Lifts there "shall be allowed only for the minimum amount necessary to accommodate a residential dock" (1.3.1(P)(1)(b)).
Scenery. The CRMC assesses every lift for its effect on "aesthetic and scenic resources" and "cumulative impacts." In Type 2 water you must also "describe the measures taken to mitigate impacts on the scenic quality of the area" (1.2.1(C)(2)(e)).

Who decides is less fixed than 1.3.1(P) makes it look. That section says every Type 2 lift "shall be referred to the Council for a hearing." But section 1.1.6 lists "boat and float lifts" among the Category B files the executive director may decide alone. That applies when the file meets the program's goals and draws no objection, and not sooner than 20 days after the staff report. Section 1.1.6 says it supersedes any reference to "review and/or action by the full council." So the practical trigger is an objection. A neighbor who objects sends the lift to the full Council. The director can also send a file there on their own.

What happened in the Narragansett case

The 2023 Superior Court decision in Squibb v. CRMC (PC-2022-02007) shows how the Type 2 test is applied. A homeowner in Narragansett applied for a dock across from Dutch Island. It reached 72 ft past mean low water and carried a 30,000 lb boat lift and a jet ski lift. CRMC staff noted that the project "requires Council review for a boat lift in Type 2 waters." A neighbor objected. The Council voted twice, as the rule requires. It approved the dock unanimously, then the lifts by 4 to 2. Its written decision is dated March 10, 2022.

The court reversed that approval on August 23, 2023. Two findings concerned the lifts:

Scenery. The Council said the design was "not uncommon for other waters of the State." The court found no finding in the record on the cumulative scenic impact of lifts that size on that shore, and no record of steps to soften it. Staff had written that the lift was "much larger than other lifts approved in the area."
Minimum necessary. The record showed the owner wanted the dock so he could launch his tender clear of rocky shoals. His own engineer said the dock could exist without the lifts. It gave no reason he could not use the dock "without the boat lifts." So nothing supported a finding that the lifts were "the minimum relief necessary."

The court also held that a lift does not need its own undue hardship variance. The lesson for a Type 2 owner is plain. Size the lift to the boat, show why the dock needs it, and put scenic mitigation in the file before anyone objects.

Design standards every lift must meet

These come from 1.3.1(P)(3) and (4). They apply in every water type where a lift is allowed.

Attachment: a lift may only be "an accessory structure connected to a fixed pier or shoreline bulkhead." It cannot hang from a floating dock or stand alone.
Height of the boat: when raised, the gunwale (the top edge of the hull) may be no higher than the pier deck. The hull bottom may be no more than 5 ft above the high tide level. Whichever is lower governs. If the lift can raise the boat higher, it needs mechanical stops.
Height of the lift: no higher than the dock's pilings, and no more than 5 ft above the pier deck, whichever is lower. The winch may sit on top of a piling.
No overhead frame: "beams and joist-like structures that sit or are fixed atop pilings are prohibited." That rules out a classic top-beam lift. Use a lift that works within those limits, such as a beamless lift or pile-mounted winches.
Setback: no part of the lift within 25 ft of the extension of a neighbor's property line. Two exceptions apply: a shared dock for two or more adjoining owners applying together, or a letter of no objection from the neighbor.
Count: no more than 2 boat lifts and 1 float lift per residential dock.
Plans: the application "will include a plan prepared and stamped by a professional engineer." The CRMC's dock checklist asks for a Rhode Island registered engineer's stamp.

The dock itself must already be approved, or be approved in the same file. Section 1.3.1(P)(2)(c) says the Council will not deliberate on a lift unless it has approved the dock. It "shall not weigh the benefits or disadvantages of a boat or float lift" when it decides the dock. A lift cannot be the reason a dock gets approved.

After construction, the as-built survey for the dock, due within 30 days, must show the length and width "including all terminal floats and boat lifts."

What is not a float lift

Many owners hoist the float and ramp out of the water for winter. The Red Book says raising them "by manual methods (manual pulleys, come-a-longs, etc.)" for off-season storage is not a float lift. The off-season runs November 1 to May 1. The exception ends the moment you install "permanent winches, pulley systems or other permanent mechanical structures, pilings, or equipment." Permanent float winches make a float lift, and that counts as your one.

A small launch device on the float is separate again. The dock standards allow mechanical gear on the terminal float for kayaks, dinghies and PWCs, but it may not stand more than 24 in above the float.

Exposed sites and eelgrass

Excessive fetch

Fetch is the stretch of open water the wind blows across to build waves. A site has "excessive fetch" if there is "a twenty degree (20º) sector over four (4) miles in any direction" of open water. At those sites the rules say "boat lifts, suitably designed and installed, are encouraged." The cost comes in the engineering:

Uplift calculations go in with the application.
Every structural element, "including the boat lift," is designed for the 100-year storm with breaking waves, to ASCE 7 (2016 edition) and FEMA's Coastal Construction Manual (FEMA 55, 2011).
An as-built plan certifying the work goes to the CRMC within 30 days.
A Rhode Island professional engineer must inspect and certify "all elements of the dock and lift system" every 5 years.

For pile and wave design in this kind of water, see tidal and saltwater installations, piling requirements and hurricane preparation.

Submerged aquatic vegetation

Submerged aquatic vegetation (SAV) means underwater plants, mostly eelgrass. Over SAV, the rules shrink a lift to tender size. Lifts for boats over 12 ft long and over 1,200 lb are prohibited there, and so are float lifts. Floats are prohibited over SAV too. Where a dock is not allowed a float, the rules allow a lift for a tender of 12 ft or less with a capacity of 1,200 lb or less. It goes near the end of the fixed T or L section, in at least 4 ft of water at mean low water.

Worked example: a tender lift over eelgrass in Jamestown

Take the CRMC public notice for 15 Dumpling Drive, Jamestown (file 2024-10-068, notice dated February 9, 2026). It describes a 131 ft fixed pier with a 4 x 20 ft terminal L and a "1200lb boat lift in a SAV location." The plans mark the water as "CRMC Type 3." The notice was a proposal open for comment, so this walks the plans against the rules. It is not a report of what the CRMC decided.

Water type: Type 3, so a lift may be allowed. Had the same shore been Type 2 in Wickford Harbor, the walk would end here.
SAV: the dock crosses eelgrass, so no float. That leaves the tender lift as the only lift option.
Size: 1,200 lb, which is the cap. A 1,500 lb lift would fall outside the tender allowance. The boat must also be 12 ft or shorter.
Depth: the rule wants 4 ft at mean low water at the lift. The notice says the pier runs 80 ft past mean low water "to achieve the required 5 feet of water depth." That needs a variance of 30 ft beyond the 50 ft length standard.
Height: the plan notes tell the builder to adjust stops so the boat's gunwale cannot rise above the fixed dock framing when raised. That is the gunwale rule built into the hardware.
The 5 ft cap: the plan puts mean high water at 3.5 ft above mean low water. Using that as the high tide level, the hull bottom may sit no higher than 8.5 ft on the plan's datum. Suppose the pier deck were at 7 ft. Then the deck would govern, because it is lower.

Change one fact. Make it a 4,000 lb lift for a 20 ft center console. Over SAV that lift is prohibited, whatever the water type.

Fees

CRMC fees are in its Management Procedures (650-RICR-10-00-1, section 1.4.6, as amended December 23, 2025). They are "summative," so lines add together, and they are non-refundable.

CRMC application fees that can apply to a residential lift (650-RICR-10-00-1, section 1.4.6)
Fee line	Amount
New residential boating facility (pier or dock)	$1,500
Modification under 50 percent of the area of an assented dock	$250
Modification of an Assent, single family home, no public hearing	$100
Assent renewal or extension, single family home	$75

The schedule has no line for a lift. A dock and lift filed together are a new facility at $1,500. For a lift added to a dock you already have, ask CRMC staff which line they will apply before you pay. The CRMC's web page also lists a $20 dock registration fee and administrative fees for work done without an Assent, starting at $500 for structures built in tidal water. The registration plate itself is required on every residential dock. A missing plate can draw a $1,000 fine.

Lifts added to existing docks are routine filings. Recent CRMC notices include a 10,000 lb lift for an existing dock on the Sakonnet River in Portsmouth (2026-06-036). There is also a 30,000 lb lift with a new pier on Mount Hope Bay in Bristol (2025-04-002).

The federal layer: the Army Corps

CRMC states that any project with work below mean high water "will require an independent federal review" by the U.S. Army Corps of Engineers, New England District. CRMC does not coordinate it. You apply to the Corps yourself, at the same time as the CRMC file.

The Corps rules have been changing. CRMC says that since November 20, 2025, piers, ramps and floats under Corps General Permit 4 no longer qualify for self-verification, even with a CRMC Assent. They need a pre-construction notification filed through the Corps' Regulatory Request System. The 2022 Rhode Island General Permits named "private boat lifts" under General Permit 4. A January 2026 law firm alert reported that the Corps is replacing New England's regional general permits with nationwide permits from March 15, 2026. CRMC also says a new nationwide permit "will replace some, but not all, of the RI General Permits." Ask the Corps which permit your lift files under before you order it.

Where this answer stops applying

Freshwater lakes and ponds. This page covers CRMC tidal and coastal pond water. Inland lakes fall under other state and local rules, not covered here.
Your water type. The rules apply by the type on the CRMC map at your exact site. A harbor can hold more than one type. Confirm yours before you design.
Variances and special area plans. Dock length, setbacks and other limits can be varied, and some areas have Special Area Management Plans with extra rules. Neither is covered here.
Datum for the 5 ft rule. The rule says "high tide level" without naming a datum. Have your engineer confirm what CRMC staff will accept.
Town permits. Building and electrical permits, HOA rules and deed restrictions sit on top. Lift wiring needs a licensed electrician and ground-fault protection, because faulty dock wiring causes electric shock drowning. See boat lift electrical.
Other states. Neighboring rules differ. See New York boat lift permits, New Hampshire boat lift permits and Maryland and Virginia boat lift permits. The layers every state shares are in boat lift permits.

Frequently asked questions

Do I need a CRMC permit to add a boat lift to my existing dock?

Yes. The Red Book lists boat and float lifts among the work that needs a CRMC Assent, and a lift is reviewed as its own accessory structure. Your dock's Assent does not cover a lift added later. You file with an engineer's stamped plan. Recent CRMC notices show lifts added to existing docks in Portsmouth and Warwick.

Can I put a boat lift on Point Judith Pond or Ninigret Pond?

Not in the Type 2 parts. Section 1.3.1(P)(3)(c) bans boat and float lifts in all Type 2 water in 16 named waterbodies, including Point Judith, Ninigret, Potter, Green Hill, Quonochontaug and Winnapaug Ponds. Any Type 1 water there is banned too. Check the CRMC water type map for your exact shore.

How high can a boat sit on a lift in Rhode Island?

When raised, the gunwale may be no higher than the deck of the fixed pier or bulkhead. The hull bottom may be no more than 5 ft above the high tide level. The lower of the two governs. A lift that can go higher needs mechanical stops. The lift itself may not stand above the dock's pilings or more than 5 ft above the deck.

How many boat lifts can a Rhode Island dock have?

Two boat lifts and one float lift per residential dock. Each must be at least 25 ft from the extension of a neighbor's property line. The exceptions are a shared dock for adjoining owners applying together, or a letter of no objection from the neighbor. Over eelgrass only a tender lift of 1,200 lb or less is allowed.

Is winching my float out of the water for winter a float lift?

Not if you use manual methods such as hand pulleys or come-alongs and store it from November 1 to May 1. The Red Book excludes that from the float lift rules. Once you install permanent winches, pulleys, pilings or other permanent gear, it is a float lift, and a dock may have only one.

How much does a CRMC boat lift permit cost?

The CRMC fee schedule has no separate lift fee. A new dock with a lift is $1,500. A modification under 50 percent of an assented dock's area is $250, and a single family Assent modification with no hearing is $100. Ask staff which line applies to your lift. Engineering and Corps filings cost extra.
