Navigating Coastal Building Codes for Custom Homes ππ

Building on the Texas coast isn’t just about creating a beautiful home—it’s also about ensuring that home stands strong against hurricanes, flooding, and salt air. Coastal building codes are in place to protect your investment and keep you and your family safe.
At South Texas Home Builders, we’re experienced in navigating these codes and making sure your dream home checks all the boxes while still reflecting your personal style.
βοΈ Step 1: Understanding State + Local Regulations
Coastal municipalities have their own rules in addition to statewide guidelines. We stay current on the specific code requirements for your build site.
β Common Requirements:
βοΈ Windstorm certification (through the Texas Department of Insurance)
βοΈ Floodplain compliance (local + FEMA)
βοΈ Coastal setback lines (from vegetation or dunes)
π‘ Builder Tip: We work directly with local officials to streamline approvals and avoid red tape delays.
π Step 2: Elevation + Foundation Requirements
Homes in flood-prone areas must be elevated to meet Base Flood Elevation (BFE) standards, which vary by zone.
β Common Coastal Foundation Types:
βοΈ Pier-and-beam construction
βοΈ Raised slabs
βοΈ Pilings for homes in V-zones (velocity flood zones)
π‘ Builder Tip: Elevated homes often capture better views—let us design your layout to take full advantage.
πͺ Step 3: Impact-Rated Materials + Hurricane Protection
Coastal codes require materials that can withstand high winds, heavy rain, and potential debris impacts.
β Code-Compliant Features Include:
βοΈ Impact-rated windows and doors
βοΈ Roof tie-downs and hurricane straps
βοΈ Rust- and corrosion-resistant fixtures
π‘ Builder Tip: Code-compliant doesn’t mean boring—we source high-style finishes that meet all regulations.
π‘ Step 4: Energy Efficiency + Sustainability
Energy codes now go hand-in-hand with building safety, even in coastal zones. We use modern methods and materials to meet or exceed efficiency guidelines.
β Common Efficiency Standards:
βοΈ HVAC systems with SEER ratings suitable for humid climates
βοΈ Spray foam or closed-cell insulation
βοΈ Smart lighting, low-flow fixtures, and energy-efficient windows
π‘ Builder Tip: Smart energy choices not only meet code—they reduce long-term utility bills and maintenance costs.
π Step 5: Permitting + Documentation
Permits are required at every stage—from design to final occupancy. We handle the paperwork so you don’t have to.
β What We Manage:
βοΈ Windstorm engineering and WPI-1 forms
βοΈ City and county permit applications
βοΈ Site-specific structural drawings
π‘ Builder Tip: Our internal team is experienced in expediting permits across multiple coastal municipalities.
