Building Permits & Regulations in Dunes West, SC: What to Know Before You Break Ground

The Town of Mount Pleasant issues your building permit, but in Dunes West the Property Owners Association's Architectural Review Board is the approval that actually determines what you can build — and it reviews far more than new construction.

Flood Zone Varies Lot to Lot

Most of Dunes West sits in unshaded Zone X, with no federal flood insurance mandate, but marsh and creek-edge lots fall into Zone AE with base flood elevations of 8 to 11 feet, and a small number of northwest Wando-facing lots sit in Zone VE. Any clearing, fill, or regrading requires a Town floodplain development permit, and a cumulative-improvement rule triggers current flood-code compliance once repairs or upgrades reach 50% of a home's fair market value within a 10-year window — relevant for any major renovation, not just new builds.

The ARB Approves Everything, Not Just New Homes

Dunes West's ARB requires approval for every exterior change — including repainting the identical color or re-roofing with matching shingles. New-home applications are due 5 business days before ARB meetings, held the 1st and 3rd Thursday of each month; non-new-home projects are due by noon the prior Tuesday. Build your schedule around the meeting calendar, not just the Town's permit timeline.

A Real Example: The Grand Oaks Tree Dispute

A cluster of diseased, decades-old oaks on Wando Plantation Way became a multi-year community issue, with a November 2024 town hall, a Town-approved removal plan finalized in July 2025, four trees approved for removal with 14 more under monitoring, and a follow-up town hall in October 2025. It's a useful reminder that mature tree canopy — a core part of Dunes West's value — comes with its own approval process before any tree tied to a build site can come down.
