Short answer: The Town of Hilton Head Island is a Class 5 community in FEMA's Community Rating System, which gives NFIP flood insurance policies in the Town a 25% discount (FEMA's list effective October 1, 2026). Under current NFIP pricing the discount applies to every Regular Program policy in the Town, including homes outside the high-risk zone. The insurer applies it automatically, but a building that doesn't comply with the Town's floodplain rules can lose it.

Key facts

  • Town of Hilton Head Island: CRS Class 5, 25% discount (FEMA, CRS Eligible Communities, effective October 1, 2026).

  • Who gets it: every Regular Program NFIP policy in a participating community, inside or outside the Special Flood Hazard Area (FEMA).
  • What it's taken off: the full-risk NFIP premium; fees and surcharges are separate.

  • Private flood policies: the CRS discount is an NFIP discount; a private insurer sets its own price.

What is the Community Rating System?

The Community Rating System (CRS) is FEMA's program that cuts NFIP flood insurance premiums in towns and counties that do more than the national minimum to reduce flood risk. Communities earn credit in four groups of activities: public information, mapping and regulations, flood damage reduction, and warning and response. The total sets a class from 10 (not participating, no discount) to 1 (45% discount), in steps of 5%.

Hilton Head Island has been in the program since 1991 and has held Class 5 since 2010. One of the Town's stricter rules is its freeboard requirement: a new home's lowest floor must be at least 3 feet above the base flood elevation or 13 feet above mean sea level, whichever is higher. The Town also reviews its repetitive loss areas and its public flood information program every year; Town Council received the 2026 update on June 9, 2026.

Does the 25% discount apply outside the flood zone?

Yes. Under FEMA's current pricing, the CRS discount applies to the full-risk premium of every Regular Program NFIP policy in a participating community, including buildings outside the Special Flood Hazard Area. The Town says the same: all FEMA flood insurance policies in the Town are eligible for the 25% discount.

This is a place where older pages are wrong. Some sites still say high-risk policies get up to 25% while properties outside the high-risk zone get only 10%. That split was the rule before FEMA's Risk Rating 2.0 pricing took over (October 2021 for new policies, April 2022 for renewals). It no longer applies.

Do I have to apply for the CRS discount?

No. The insurer applies it based on the property's community. What you should do is check that it's there: the discount shows on the NFIP declarations page or premium breakdown. If you're comparing a seller's existing policy with a new quote, check both.

A property in unincorporated Beaufort County gets the County's discount instead of the Town's. Both are Class 5 on the October 2026 list. Some addresses that portals call "Hilton Head" are on the mainland and in a different community, so confirm the jurisdiction on the County property record. The Town of Bluffton, SC doesn't appear on FEMA's October 2026 list at all, so don't assume a Bluffton home gets a CRS discount.

Can a Hilton Head home lose the CRS discount?

Yes. FEMA says a policy can lose the discount if the structure doesn't comply with the community's floodplain management rules, and tells those owners to work with the local floodplain administrator to regain it. On Hilton Head the usual problems are:

  • A ground-level enclosure under an elevated house that has been finished, heated, cooled or turned into living space. The Town limits that space to parking, building access and limited storage.
  • Missing or blocked flood openings in an enclosure. The Town requires at least 1 square inch of opening per square foot of enclosed area, at least two openings, with the bottom no more than 1 foot above grade.
  • A large remodel or addition done without bringing the building into compliance after it crossed the Town's 49% substantial improvement threshold.

The same problems can affect the price beyond the discount, and a non-compliant building can be hard to insure at all. Ask the seller about any downstairs bedroom, game room or bath, check the permit history, and compare what you see to the elevation certificate's description of the enclosure.

Could the discount change?

It could, in either direction. FEMA reviews communities' CRS classes, and the Town's class depends on keeping its program up. Nationally, FEMA released a revised 2025 CRS Coordinator's Manual and said in March 2026 that it has no plans to end the CRS and that discounts continue. As of FEMA's October 1, 2026 list, the Town is Class 5. We'll update this page when the class changes.

What does the 25% mean in dollars?

It's 25% off the full-risk NFIP premium for that building, so the dollar amount depends entirely on the house. We don't publish typical flood premiums, because FEMA prices each building on its own elevation, distance to water, foundation and rebuilding cost. Get a quote for the specific address, with its elevation certificate, and check that the CRS line is on it.

How we help

We'll confirm from the County record whether a home is inside the Town limits, pull its elevation certificate and permit history, and flag anything under the house that looks like finished space so your insurance agent and inspector can look at it before you're committed.

Questions

What CRS class is Hilton Head Island?

Class 5, worth a 25% discount on NFIP flood insurance, on FEMA's list effective October 1, 2026. The Town has been in the program since 1991 and at Class 5 since May 1, 2010.

Does the CRS discount apply to private flood insurance?

The CRS discount is part of NFIP pricing. A private flood insurer sets its own rates and may or may not reflect the Town's program, so compare a private quote against an NFIP quote that already includes the 25%.

Does Bluffton get the same flood insurance discount?

The Town of Bluffton, SC is not on FEMA's October 2026 CRS list, so it has no CRS discount on that list. Unincorporated Beaufort County is Class 5 (25%). Check the community for the specific address.
