How South Carolina Coastal Regulations Affect Your Luxury Home Purchase
Myrtle Beach Luxury Home is a boutique real estate experience serving buyers and sellers across Myrtle Beach and the surrounding areas.
The head agent, Rick Sarver, has years of real estate and business-owner experience and has lived in the Myrtle Beach area for over 15 years.
Every client works directly with Rick from first showing through closing.
South Carolina has some of the most detailed and actively enforced coastal construction regulations on the East Coast — and buyers who don't understand them before going under contract on a Grand Strand oceanfront or tidal creek-adjacent property routinely discover post-closing that what they planned to build, renovate, or expand is not legally permittable. The regulatory framework is straightforward once you understand the structure, but it affects every oceanfront and coastal property on the Grand Strand in ways that do not appear in listing descriptions or Zillow data.

The Two Jurisdictional Lines Every Coastal Buyer Must Understand
South Carolina's Bureau of Coastal Management — formerly DHEC-OCRM, now operating under the SC Department of Environmental Services following a 2024 state government restructuring — establishes and enforces two jurisdictional lines on every oceanfront parcel in the state under S.C. Code Ann. § 48-39-280.
The baseline is the more seaward of the two lines, set at the crest of the primary oceanfront sand dune — defined as a dune with a minimum height of 36 inches, forming a nearly continuous ridge for 500 shore-parallel feet. The setback line is established landward of the baseline at a distance equal to 40 times the average annual erosion rate for that specific stretch of coastline, with a minimum of 20 feet landward of the baseline even where the shoreline has been stable. These lines are reviewed every seven to ten years and are subject to revision — meaning a property that was outside the setback area when originally built may find itself on the wrong side of an updated line after the next review cycle. The most recent Phase 1 public comment period for updated jurisdictional lines closed in January 2026.
Between the baseline and the setback line, the Bureau exercises regulatory permitting authority over habitable structures, pools, decks, gazebos, dune walkovers, landscaping, fencing, service lines, and other alterations. Seaward of the baseline, construction of new shore-parallel erosion control structures — seawalls, revetments, bulkheads — is prohibited. Existing structures may be maintained or repaired with prior authorization, but new ones cannot be added.
What Buyers Are Actually
Prohibited From Doing
The practical implication for Grand Strand luxury buyers is significant. A buyer who purchases an oceanfront estate on the Golden Mile or in Briarcliffe Acres with plans to add a pool, expand a deck, install a fence along the dune, or add a second structure may discover that all or part of the planned improvement falls within the setback area or seaward of the baseline — requiring a Bureau of Coastal Management Critical Area Permit that may be difficult to obtain or may simply be denied. Any work exceeding $5,000 within the critical area requires both a licensed South Carolina contractor and a site-specific Critical Area Permit filed with the Bureau.
Buyers planning to demolish and rebuild — a common scenario on the Golden Mile where older estates sit on high-value lots — face the strictest constraints. New construction must be sited as far landward as the lot allows, and structures damaged beyond 50 percent of their value by storm may be subject to additional setback requirements before reconstruction is permitted.
How Georgetown County Adds Another Regulatory Layer
Properties in Georgetown County — including Pawleys Island, Litchfield Beach, and DeBordieu Colony — fall under Georgetown County's own building jurisdiction in addition to state Bureau of Coastal Management authority. Permitting requirements, building codes, and coastal construction review processes differ from Horry County. Buyers relocating from outside South Carolina frequently assume that Myrtle Beach-area coastal rules apply uniformly across the Grand Strand — they do not. Georgetown County's separate jurisdiction adds a review layer and timeline that can affect construction planning and closing timelines on coastal properties.
Talk to Rick Before You Make an Offer on Any Coastal Property
SC Bureau of Coastal Management jurisdictional lines, Critical Area Permit requirements, and county-level permitting differences are all verifiable before you go under contract — but only if your agent knows where to look and makes it a standard part of due diligence. Rick Sarver at Myrtle Beach Luxury Home reviews Bureau of Coastal Management setback designations, verifies critical area boundaries, and confirms county permitting jurisdiction on every oceanfront and tidal creek-adjacent transaction before clients finalize any offer. Contact Rick directly before you commit to a coastal property on the Grand Strand.
