Building a new home near the South Carolina coast used to be a straightforward dream: pick your lot, pick your view, and let the tide do the rest. But 2025 has rewritten the script. Between sky-high insurance premiums, new FEMA flood-zone shifts, and rebounding construction material costs, today’s coastal builder faces more fine print—and expense—than ever before.
If you’re planning to build in Myrtle Beach, Murrells Inlet, or Pawleys Island, or you’re eyeing one of Carolina Crafted Homes’ communities near the Grand Strand, here’s what you need to budget for beyond your blueprints.
1. The 2025 Market Reality Check: A Buyer’s Market with Builder Pressures
Houzeo’s April 2025 housing data paints a picture of South Carolina’s cooling—but still competitive—market. The median home price sits around $380,900, up less than 1% year over year. Inventory has climbed 15.8% to more than 28,000 homes, while average market time has stretched to nearly 70 days.
On paper, that sounds like relief for buyers. But for builders, especially along the coast, it’s a double-edged sword. As supply rises, profit margins tighten, and hidden costs—insurance, permitting, and flood compliance—cut deeper into already thin returns.
In short, 2025 may be the best time to buy, but it’s the toughest year in a decade to build affordably near saltwater.
2. The Insurance Crunch: Storm Risk Meets Premium Shock
Homeowner’s insurance in coastal South Carolina has quietly become the fastest-rising line item on any build sheet. Major insurers are tightening coverage terms across Horry and Georgetown counties, with average annual premiums climbing 20–35% since 2023, according to local underwriting data.
Builders constructing within a mile of the ocean now face:
Wind-pool surcharges mandated by the SC Wind and Hail Association
Higher replacement-cost coverage requirements for new custom builds
Mandatory secondary coverage for flood and wind events
Even inland neighborhoods like Carolina Forest are feeling ripple effects, as proximity risk maps expand under new reinsurance models.
The result: insurance now represents an additional $4–7 per square foot on many coastal builds—often more than the total cost of upgraded finishes.
3. FEMA’s Flood-Zone Shuffle: New Lines, New Rules
The 2025 FEMA flood map updates quietly reclassified parts of the Grand Strand, especially near Socastee, Cherry Grove, and Surfside Beach. Builders who once designed on “moderate risk” plots are now discovering AE or VE flood zones, which trigger stricter elevation requirements and mandatory flood insurance.
Here’s what that means in dollars:
Lot prep costs rise 10–15% due to fill and foundation adjustments.
Survey and engineering fees climb as more certifications are required.
Flood insurance policies can add $2,000–$6,000 annually per home.
Worse, these changes hit mid-project—catching many builders mid-permit with new compliance obligations. For homeowners, it translates to long-term costs that never show up in initial quotes.
4. Material Costs: The Rebound Few Saw Coming
After a brief cooldown in 2023–2024, construction material prices surged again in 2025, driven by regional demand and supply-chain realignments. The National Association of Home Builders reports:
Lumber prices up 11% year-to-date
Concrete up 8%
Vinyl siding and windows up 5–7%, especially along the coast
Why? Coastal codes now require impact-rated materials, meaning heavier glass, reinforced framing, and corrosion-resistant fasteners.
Builders in Market Common and Grande Dunes report that material upgrades alone add $25,000–$40,000 per home compared to inland builds—a painful but necessary investment for longevity and resale value.
5. Labor and Logistics: When Sand Meets Scheduling
It’s not just the stuff you build with—it’s who builds it. Skilled trade shortages continue to pinch Myrtle Beach’s construction industry. Crews are booked months out, and delivery delays at the Port of Charleston ripple down to local suppliers.
Transportation costs for heavy materials rose nearly 12% in the first half of 2025, and the increased use of coastal-grade materials means longer lead times. A home that once took eight months to complete may now need twelve, simply due to supply gaps.
In a buyer’s market, those delays carry financing implications: more interest, more carrying costs, and more pressure to deliver under tighter margins.
6. Building Smarter, Not Just Bigger
Despite these challenges, opportunities remain for savvy builders and buyers. Carolina Crafted Homes and other coastal-savvy builders are adapting through:
Elevated design that meets new flood standards without excess cost
Pre-engineered building packages that cut labor time
Insurance-bundled programs that lock rates before closing
Energy-resilient materials that qualify for 2025 state tax incentives
For buyers, it’s more important than ever to review insurance and zoning costs before signing. Ask your builder to itemize elevation prep, wind-mitigation costs, and flood insurance assumptions right on your proposal.
Coastal Dreams Need Coastal Math
Building near the ocean still pays off in lifestyle and long-term value. But 2025 proves that the biggest costs often hide between the lines of your building permit.
Whether you’re planning in Carolina Forest, Murrells Inlet, or Ocean Isle, make sure your coastal dream includes a contingency for risk-driven realities—because salt air isn’t the only thing rising along the Grand Strand.

FAQs
1. Why are insurance rates rising for coastal South Carolina homes in 2025?
Because of increased storm risk modeling and reinsurance tightening, coastal premiums rose 20–35% since 2023. Horry and Georgetown counties face the largest hikes due to wind exposure and FEMA flood reclassifications.
2. How have FEMA flood maps changed in Myrtle Beach and surrounding areas?
The 2025 updates expanded AE and VE zones, requiring higher foundations and more documentation. Many previously moderate-risk areas now need elevation certificates and mandatory flood insurance.
3. Are construction material costs still climbing in 2025?
Yes. Lumber, concrete, and impact-resistant materials are all up between 8–12% year-to-date, driven by demand for hurricane-compliant construction and lingering global supply bottlenecks.
4. How do builders in Myrtle Beach offset these rising costs?
Smart builders use pre-engineered plans, bulk insurance agreements, and coastal-resilient materials that reduce maintenance and energy costs long-term.
5. What’s the outlook for home prices in South Carolina for 2026?
Analysts expect moderate growth of 1–3%, with coastal zones stabilizing as insurance and supply costs peak. The market remains favorable for buyers through mid-2026.
