Coastal & Waterfront Home Builder in Pinellas County
Central Builders Group is a design-build general contractor that builds custom homes on waterfront, barrier-island, and flood-zone lots across Pinellas County. Flood elevation, storm surge, and wind code shape the design from the first drawing, and the whole build runs under one fixed-price contract.
Coastal homes are one part of our custom home building across Pinellas County. This page covers what changes when the lot is on the water.

Where Are You Starting?
I Own a Waterfront or Flood-Zone Lot
Bring your address. We check the flood zone, base flood elevation, setbacks, seawall condition, and soil before any design work begins.
My Home Was Damaged in a Storm
Repair, raise, or rebuild. We look at the damage, the 50% rule, and your lot, then lay out the options in plain numbers from your property.
I’m Buying a Coastal Lot
Talk to us before you close. Flood zone, setbacks, and seawall condition can change what you can build and what it costs.
I Already Have Plans
Share your drawings. We review them for coastal code, foundation type, and buildability on your specific lot.
Coastal Construction
What Makes Building on the Coast Different
On a waterfront lot, the water decides a lot of the design before you pick a single finish. How high the house sits, what holds it up, how the roof stays on, and what the permit needs all come from the lot’s flood zone and wind exposure. A plan that ignores those things gets redrawn in plan review, or worse, after the framing is up.
That’s why every coastal project starts with the lot, not the floor plan.
Flood Zones
Flood Zones and Elevation
Zone AE vs. Zone VE
Most waterfront lots in Pinellas County fall in one of two FEMA flood zones.
Zone AE
Zone AE covers most bayfront and canal lots, including much of Snell Isle, Shore Acres, and Venetian Isles. The home has to sit at or above the base flood elevation.
Zone VE
Zone VE covers lots exposed to coastal wave action, including parts of St. Pete Beach and Pass-a-Grille. VE adds stricter rules: the home has to sit on an open foundation like pilings or columns, with no solid walls holding it up below the flood line.
Base Flood Elevation and Freeboard
Your lot’s Base Flood Elevation (BFE) sets the minimum height of the lowest floor. Pinellas County’s floodplain guidance calls for new and substantially improved homes to sit at least one foot above BFE. Individual cities can set their own requirement, so we confirm it with your jurisdiction during the lot evaluation. You can look up your BFE on the county’s Construction in a Floodplain resource.
What Goes Below the Living Space
The space under an elevated home is usually parking, storage, and building access. In AE zones, enclosed areas below the flood line need flood vents so water can pass through. In VE zones, any walls below the flood line have to be breakaway walls designed to give way in a storm without damaging the house.
Engineered for the Water
Foundations Built for Surge
Driven Piles
On a lot exposed to storm surge, a slab is what the water undermines first. Driven piles carry the home’s load deep below the scour zone and let water and debris pass underneath instead of pushing against a solid base.
Stem Walls and Raised Slabs
On many AE lots, a stem wall or raised slab can put the living space at the required height without piles. Which one fits depends on the flood zone, the required elevation, and the soil.
Soil and Groundwater
Coastal Pinellas has a high water table and sandy, shell-heavy soils. A geotechnical review before design tells the engineer what the ground can carry and how deep the foundation needs to go.
Wind and Hurricane Code on the Water
A Continuous Load Path
Every connection from the roof to the foundation is engineered to hold together under hurricane wind loads, so the roof, walls, and floor act as one structure.
Impact-Rated Openings
Most coastal Pinellas lots sit in Florida’s wind-borne debris region. That means windows and doors need impact-rated glass or an approved protection system. On a waterfront home with a wall of glass facing the view, that choice shapes both the design and the budget.
Roofing and Salt-Air Materials
Roofing has to be rated for coastal wind exposure. Near the water, salt air also eats exposed metal, so we spec stainless or coated fasteners and connectors, and corrosion-resistant trim and flashing.
Waterfront Site Work
Seawalls, Setbacks, and Waterfront Site Work
Seawall Condition
A failing or undersized seawall affects the foundation design and becomes a long-term cost. We look at it before design starts, not after.
Shoreline Setbacks
Setbacks from the seawall or mean high water line are added to the normal yard setbacks. On a tight waterfront lot, they can decide where the house sits and how big it can be.
Docks and Shoreline Work
Dock and shoreline work needs permits from agencies beyond the city building department, such as the U.S. Army Corps of Engineers, the Florida Department of Environmental Protection, and the Southwest Florida Water Management District, and they run on their own timelines. We plan them alongside the home’s permit, not after.
After the Storm
Rebuild, Renovate, or Raise After a Storm
-
The FEMA 50% Rule
If repairs or improvements cost more than half of a flood-zone home’s market value, the whole house has to be brought up to current flood code. After Helene and Milton, that rule is deciding a lot of projects across coastal Pinellas.
-
When a Rebuild Makes More Sense
On many older waterfront homes, meeting current code means raising the house or rebuilding it. When the work gets that big, a new home built to today’s standards is often the better use of the money.
-
Raising Your Existing Home
Some homes are worth keeping. We also elevate existing homes, lifting the structure onto a new foundation at the required height.
-
How We Help You Decide
We walk the property, review the damage and the flood requirements, and lay out what each path involves for your home. Then you choose.
Featured Project
Case Study: Gulf-Front Rebuild in Redington Shores
A hurricane-damaged beachfront home in Redington Shores was beyond practical repair, so the owners chose to replace it. We designed and built an elevated coastal home under one contract.

- Site
- Tight beachfront lot, limited access
Why piles instead of a slab?
On a beachfront lot, a slab is what storm surge undermines first. Driven piles carry the load below the scour zone and let water pass beneath the home. It’s the foundation that survives the next storm, not just this one.
Why raise the living space?
The original home was built to an older, lower standard. Rebuilding put the living space above today’s base flood elevation instead of the old one, which cuts long-term flood exposure and affects insurance.
How do you build for Gulf wind?
A beachfront house takes wind loads inland homes never see. The block and framing were engineered for coastal force transfer, with the connections and load paths that keep an elevated home rigid in a storm.
How did a tight lot get built?
Limited staging meant every trade had to be sequenced precisely. That only works when one team controls the schedule.
The Design-Build Advantage
Why Fixed-Price Design-Build Matters on the Coast
One Team Keeps It in Sync
On the coast, wind-load engineering, flood elevation, and permitting all have to agree before a wall goes up. Every handoff between separate firms is a chance for them to fall out of sync. Under one contract, they don’t. Here’s how the design-build process works from first drawing to final inspection.
A Fixed Price Before Work Begins
Coastal builds carry more unknowns, which is exactly when an open-ended bill hurts most. We price the job before it starts. You sign a fixed-price contract, and any change is approved in writing first.
The Owner on Your Job
David Gayhart stays involved from the first site walk to the final inspection. After Hurricane Helene flooded homes across St. Pete, he was at a client’s house the next morning hauling out debris.

Cost
What Drives the Cost of a Coastal Home
The same size home costs more on the water. The main drivers:
- Foundation type
- Piles and raised foundations cost more than a slab.
- Elevation height
- The higher the required floor, the more structure underneath.
- Openings
- Impact-rated windows and doors across a view-facing design.
- Engineering
- Wind, flood, and geotechnical work specific to your lot.
- Site work
- Seawall, fill, drainage, and limited access on tight lots.
A real number comes from your plans and your lot. We price every coastal home with a fixed-price contract before work begins.

Coastal Build Timeline
Coastal homes follow the same phases as any custom home, but a few run longer. Design and engineering take more time when elevation, piles, and wind loads are in play. Flood-zone and barrier-island lots usually take longer in plan review. Elevation certificates are required during construction and at the end to confirm the home sits where the permit says it does.
Common Questions
Coastal Home FAQs
Questions about building on a waterfront or flood-zone lot in Pinellas County? We’ve answered the most common ones below.
Ask Us Directly →
Can I build a home on a lot in a VE flood zone?
Yes. VE lots require an open foundation, usually pilings, with the lowest structural member above the required elevation and only breakaway walls below it. We confirm the exact requirements during the lot evaluation.
How high does my new home have to be?
At or above your lot’s Base Flood Elevation, plus any freeboard your jurisdiction requires. Pinellas County’s guidance calls for at least one foot above BFE. We confirm the number for your lot before design starts.
Do I need pilings?
On VE lots, yes. On many AE lots, a stem wall or raised slab can work instead. The flood zone, required height, and soil decide it.
What can go under an elevated home?
Parking, storage, and building access. Enclosed areas in AE zones need flood vents, and walls below the flood line in VE zones have to be breakaway walls.
Will building higher lower my flood insurance?
Often, yes. Building above the minimum elevation can reduce premiums over time. Your insurance agent can price the difference for your specific home.
Should I repair or rebuild my storm-damaged home?
It depends on the damage, your home’s value, and the 50% rule. If repairs pass half the home’s market value, the house has to meet current flood code, which often makes raising or rebuilding the better option. We walk you through each path for your property.
Do you handle the permits and flood paperwork?
Yes. We handle permitting with your city or Pinellas County, the flood-zone requirements, and the elevation certificates through final inspection.
