Brunswick County Insurance Rate Increase Explainer

Homeowners across Brunswick County, NC are opening renewal notices and finding significantly higher premiums — sometimes hundreds or even thousands of dollars more than last year. The increases aren't random, and they aren't a mistake. Brunswick County sits in one of North Carolina's 18 NCIUA-designated coastal counties, which means most homeowners here carry multiple insurance policies, and several of those policies are seeing rate adjustments at the same time. Understanding why your insurance is going up — and what you can actually do about it — starts with understanding how coastal coverage in Brunswick County works in the first place.

Why Brunswick County Insurance Rates Are Rising in 2025 and 2026

There's no single rate increase driving up costs in Brunswick County. What most homeowners are experiencing is the compounding effect of adjustments across multiple policies and programs hitting at roughly the same time.

On the homeowners insurance side — the HO-3 policy that covers your structure and contents — carriers across North Carolina have been filing for and receiving rate increases over the past several years. Reinsurance costs (the insurance that insurance companies buy to protect themselves against catastrophic losses) have climbed sharply since 2020. Construction material costs remain elevated compared to pre-pandemic levels. And the frequency of severe convective storms — hail, tornadoes, straight-line winds — across the Southeast has driven up losses even in years without a named hurricane making landfall in North Carolina.

Then there's flood insurance. The National Flood Insurance Program's Risk Rating 2.0 methodology, which FEMA began rolling out in October 2021 for new policies and applied to renewals starting in April 2022, fundamentally changed how flood premiums are calculated. Instead of relying primarily on whether a property sits inside or outside a mapped flood zone, Risk Rating 2.0 factors in a property's specific distance to water, elevation, flood frequency, cost to rebuild, and the types of flooding it faces — river overflow, storm surge, coastal erosion, heavy rainfall. For many Brunswick County properties — especially those near the Intracoastal Waterway, the Cape Fear River, Lockwood Folly River, Shallotte River, or the oceanfront communities from Sunset Beach to Caswell Beach — Risk Rating 2.0 has meant meaningful premium increases that are being phased in over multiple years. NFIP rules cap annual increases at 18% per year for most policies, so if your actuarial rate jumped significantly under the new methodology, you may see 18% increases year after year until your premium reaches its full-risk rate.

And for properties in the beach and coastal communities of Brunswick County — Ocean Isle Beach, Holden Beach, Oak Island, Caswell Beach, Sunset Beach, Bald Head Island — wind and hail coverage through the NCIUA (NC Beach Plan) adds another layer. The NCIUA has its own rate-setting process, and dwelling rates in the beach territory have been under pressure from the same reinsurance and catastrophe modeling trends affecting the broader market.

When you add a homeowners increase, a flood increase, and a wind and hail increase together — across three separate policies, each with its own rate cycle — the cumulative effect on your total annual insurance cost can be substantial.

How the Three-Policy Coastal System Affects Your Total Cost

Most homeowners in Brunswick County need three separate insurance policies to be fully covered. This structure is unique to the 18 NCIUA-designated coastal counties in North Carolina, and it's the reason a "rate increase" in Brunswick County is almost never just one increase.

Homeowners insurance (HO-3) covers your dwelling, other structures, personal property, liability, and additional living expenses — but in coastal counties, the policy typically excludes wind and hail damage entirely. That exclusion is the most important thing most Brunswick County homeowners don't realize until they file a claim.

Wind and hail insurance — written through the NCIUA/NC Beach Plan or the NCJUA, depending on your property's location within the county — covers the wind and hail peril that your homeowners policy excludes. If a hurricane or tropical storm damages your roof, siding, windows, or causes a tree to fall on your house, this is the policy that responds. Properties closer to the coast in Brunswick County are typically written through the NC Beach Plan (NCIUA), while properties further inland may be written through the NCJUA or may have wind coverage included in their homeowners policy. The dividing line isn't always intuitive, and it matters for both your premium and your coverage.

Flood insurance — either through the NFIP or through a private flood carrier — covers damage from rising water. This is never included in a homeowners policy, even during a hurricane. If storm surge pushes water into your home on Oak Island, or if the Lockwood Folly River overflows into properties along its banks, or if heavy rainfall floods a home in Leland or Shallotte that's nowhere near the coast, the only policy that pays is a standalone flood policy.

Each of these three policies has its own carrier (or government program), its own renewal date, its own rate-setting process, and its own deductible. When people say "my insurance went up," they're usually talking about the total across all three — and the increases are often staggered across different months, making it feel like a constant drumbeat of bad news.

What's Driving Costs Beyond the Rate Filings

Rate filings and regulatory approvals get the headlines, but several other factors are quietly pushing up what Brunswick County homeowners pay.

Replacement cost inflation. Your dwelling coverage limit is supposed to reflect what it would cost to rebuild your home today — not what you paid for it, and not what it was worth five years ago. Lumber, concrete, roofing materials, labor, and contractor availability in Brunswick County have all changed since 2020. If your carrier updates your replacement cost estimate upward, your premium goes up even if the rate per dollar of coverage stays flat. This is a particularly significant factor in Brunswick County, where the construction boom in communities like Leland, Bolivia, and the beach towns has kept contractor demand — and pricing — elevated.

Deductible structures. Coastal wind and hail policies typically carry percentage-based deductibles — often 1%, 2%, or 5% of the dwelling coverage amount — rather than flat dollar amounts. As your dwelling value increases, your deductible increases in dollar terms, but so does the premium. And if you're carrying a lower percentage deductible for better claim protection, you're paying more for that privilege than you were a few years ago.

Claims history — yours and your neighbors'. Your individual claims history affects your homeowners premium, but so does the aggregate loss experience in your area. Brunswick County has been fortunate to avoid a direct major hurricane landfall in recent years, but Hurricane Florence in 2018 caused significant flooding across the county, and the cumulative effect of tropical storms, nor'easters, and severe weather events over the past decade contributes to how carriers price risk here. Even a near-miss hurricane that causes no claims in Brunswick County can affect reinsurance pricing for the following year.

Coastal erosion and barrier island risk. Bald Head Island, Caswell Beach, Oak Island, and Holden Beach all face ongoing shoreline change. Carriers and catastrophe modelers factor erosion trends into their risk assessments. Properties that were 200 feet from the ocean a decade ago may be closer now, and that proximity affects how both wind and flood risk are priced.

What Brunswick County Homeowners Can Actually Do About Rising Rates

You can't control reinsurance markets or FEMA's rating methodology, but there are concrete steps that can affect what you pay.

Have all three policies reviewed together. Most homeowners look at each policy in isolation — they shop their homeowners insurance without considering how changes to deductibles or coverage limits interact with their wind/hail and flood policies. An independent agent can look at the full picture and identify where adjustments to one policy might offset costs or close gaps in another. For example, raising your wind/hail deductible from 1% to 2% typically produces a meaningful premium reduction — but you need to understand the dollar amount you'd be responsible for in a claim before making that change.

Verify your dwelling coverage amount. Overinsurance costs you money on every renewal. If your carrier's replacement cost estimate seems high, ask for the methodology. In some cases, the estimate can be adjusted with documentation. Underinsurance, on the other hand, can trigger coinsurance penalties on claims — so the goal is accuracy, not just the lowest number.

Ask about mitigation credits. The NCIUA offers credits for certain wind-resistive features — hurricane straps or clips, reinforced roof decking attachment (8d nails at 6-inch spacing on the edges and 12-inch spacing in the field, for example), impact-resistant glazing or shutters, hip roofs, and secondary water resistance. If your home already has these features, you may be eligible for credits you're not currently receiving. If your home doesn't have them, some retrofits — particularly roof deck attachment upgrades done during a re-roof — can pay for themselves in premium savings over a few years.

Review your flood policy type and coverage. If you're currently on an NFIP policy and your premium is increasing under Risk Rating 2.0, a private flood policy may offer comparable or better coverage at a lower cost — depending on your property's specific characteristics. The reverse can also be true. Private flood isn't available for every property, and it isn't always cheaper, but it's worth quoting. If your property is in a CBRA (Coastal Barrier Resources Act) zone — and parts of Brunswick County are — you're ineligible for NFIP coverage entirely and must use private flood. Harbor can help you determine which option fits your situation.

Check your NFIP policy for CRS discounts. Some Brunswick County municipalities participate in FEMA's Community Rating System (CRS), which earns NFIP policyholders a discount based on their community's floodplain management efforts. If your community participates and you have an NFIP policy, the discount should already be applied — but it's worth verifying.

Don't drop flood coverage to save money. This is the most common and most dangerous response to rising premiums. Over 20% of NFIP flood claims come from properties outside designated high-risk flood zones. Brunswick County's geography — low elevation, tidal rivers, poor drainage in many inland areas, and exposure to both storm surge and heavy rainfall flooding — means flood risk isn't limited to the oceanfront. If your lender requires flood insurance, you can't drop it anyway. If they don't require it, that doesn't mean you don't need it — it means your property may sit in a moderate-risk zone where flooding still happens.

Why an Independent Agent Matters When Rates Are Rising

When premiums increase across the board, the difference between carriers widens. One carrier's 12% increase applied to an already-competitive base rate may still be less expensive than another carrier's 5% increase applied to a rate that was too high to begin with. An independent agency shops multiple carriers for every policy — homeowners, flood, and wind/hail — rather than offering only one company's products.
