The estimate for a cedar-shingled cape on Shelter Island lands on the kitchen table. Before anyone argues about shingle color, one number on it matters to the town: the total. Shelter Island draws its permit line at $10,000. At or under it, nonstructural work goes ahead without a building permit. Over it, the paperwork starts.
The $10,000 line in Shelter Island’s code
Section 43-6 of the town code requires a building permit before anyone starts the “erection, construction, enlargement, alteration, removal, improvement, demolition” of a building, “except that no building permit shall be required for nonstructural work at a total cost not exceeding $10,000.” That wording comes from Section 43-6 A as the Town Board printed it in a draft amendment on its August 10, 2026 agenda, and the $10,000 sentence shows no sign of a change.
The code never says whether a tear-off counts as nonstructural. It never mentions roofing at all. The Building Department fills that gap in practice: its fee schedule has a “Roofing-Siding” line, and its online system takes roofing permits. Hold your contract total up against $10,000. If new plywood, rafters or a dormer show up in the scope, treat the job as structural until the department tells you otherwise.
| Roof job on a Shelter Island house | Where it falls |
|---|---|
| Nonstructural work, total cost $10,000 or less | No building permit under Section 43-6 |
| Nonstructural work, total cost over $10,000 | General permit rule applies, Roofing-Siding fee $200 |
| Rafter, sheathing or framing changes | Likely structural, which the cost exemption does not cover, so ask the department |
| Roof-mounted solar panels | $200 permit plus the Solar Panel Fast Track Application |
A rewrite of Chapter 43 is on the table
At its August 10, 2026 meeting the Town Board set an August 31 public hearing on “A Local Law Amending Chapter 43, Building Construction.” The draft rewrites the exemption list in Section 43-6 but, as printed, keeps the $10,000 sentence. It would take effect on filing with the Secretary of State or on January 1, 2027. We found no record yet of whether it passed, so ask the department which version it is working from.
What the island’s permit desk charges
The fee schedule the town posts is still titled “2022 Building Department Fees,” and the Town Board’s July 28, 2026 work session agenda listed a “Building Department fees review.” Confirm the amounts when you file.
| Item | 2022 schedule |
|---|---|
| Roofing or siding permit | $200 |
| Roof-mounted solar panels | $200 |
| Fireplaces, wood stoves and chimneys | $200 |
| Revision filed after notifying the department | $150 |
| Revision made without notifying the department | $500 |
| Re-inspection after a failed inspection | $75 |
| Renewal of an expired permit | 25 percent of the original fee, $150 minimum |
| Residential certificate of occupancy | $150, charged when the permit is issued |
Paying online by card adds a 2.45 percent convenience fee, with a $1.75 minimum. An electronic check adds a flat $1.75. One thing the schedule leaves open is whether the certificate of occupancy charge lands on a roofing-only permit, so ask.
Filing through CitySquared
Roofing, siding and irrigation renewal permits “can automatically be applied for and paid for” online, the Building Department says. Register on CitySquared with an email and password, pick Apply for Permit, and the department reviews the filing and emails back the next steps. Those confirmations come from an sca-corp.com address, so check the spam folder if nothing shows up.
Some jobs need more than the online form. The paper application, dated July 1, 2025, shows what the department expects. Every permit needs a survey of the property, though staff can waive it for repairs that do not affect setbacks. The permit stays on site during the work. The owner or contractor books the inspections, and whoever signs agrees to close the permit and obtain a certificate of occupancy or completion. If a contractor files for the owner, the town’s homeowner authorization form has to be notarized.
You’ll find the Building Department at Town Hall, 38 North Ferry Road, Monday to Friday, 8 a.m. to 4 p.m., or at 631-749-0772. Its page also notes that the 2025 New York State Energy Code took effect on December 31, 2025.
Shelter Island’s own contractor license
Off-island crews trip on this one. The town FAQ says home improvements “must be performed by a licensed contractor, holding a Shelter Island license,” and adds that “not all off-island contractors have a local license.” The permit application even has a line for the home improvement license number.
The license costs $250. A contractor applies with a check to the Town of Shelter Island, a liability certificate naming the town as certificate holder, and a workers’ compensation certificate or a Form CE-200 exemption. Chapter 79 of the town code is the law behind it, and the code’s disposition list shows a Home Improvement Contractors amendment adopted October 22, 2021. Suffolk County runs a separate home improvement license, which our Suffolk license guide covers.
Getting a roofing crew across by ferry
Roofing trucks and dumpsters cross on the North Ferry or the South Ferry, and both companies price trucks by size. The fare is not a permit cost, but it ends up somewhere in your estimate.
| Vehicle | North Ferry | South Ferry |
|---|---|---|
| Pickup or van under 22 feet | Auto rate, $16 one way | $18 one way, $27 round trip |
| Two-axle box truck or flatbed | $16 for the first 18 feet, plus $1.29 per added foot | Length in feet minus 2, one way, at 22 feet and over |
| Loaded dumpster or roll-off | $94 | $70 one way for 3 axles, $75 for 4 axles |
| Boom truck, 2 or 3 axles | Not listed, call | $50 one way, $90 round trip |
| Crane | Not listed, call | $100 one way, $180 round trip |
South Ferry runs between Shelter Island and North Haven. Its schedule is dated May 12, 2025, it takes cash only on board, and round trips have to finish the same day. North Ferry’s truck page carries no date, measures length including cab and overhang, and warns that very heavy low-clearance vehicles may have to wait for high tide. Before sending a heavy load, call North Ferry at 631-749-0139.
Dering Harbor runs its own building code office
Suffolk County lists one incorporated village in the Town of Shelter Island: Dering Harbor. Under Chapter 45 of the village code, its Code Enforcement Officer enforces the state building code inside the village. So a Dering Harbor roof starts with a call to village hall at 631-749-0020, not the town.
The village also controls the clock. Its Chapter 72 says the village has fewer than 40 homes, most used on weekends and in summer. From Columbus Day until May 1, construction and deliveries are allowed Monday through Saturday, 8 a.m. to 6 p.m., except Sundays, holidays and Thanksgiving weekend. For part of the rest of the year the chapter bars construction work and deliveries on Saturdays, Sundays and holidays, with added limits around July 4. It also bans a radio or phone playing loud enough to be heard past the property line during the work. Get the current calendar from the village before you book a ferry slot.
