A lot of homes on Treasure Island and the nearby beaches were built long before today's flood rules. After a big storm, many owners hear the same news from the city: the damage is serious enough that the house has to be brought into compliance with current flood elevation rules before it can be repaired. That usually leaves two real paths. You can raise the house you have, or you can tear it down and build a new elevated home.
Neither choice is right for everyone. This guide walks through how we think about it with homeowners, what drives the cost, and how flood insurance can help.
Why the question comes up at all
Under the National Flood Insurance Program, communities like Treasure Island have to enforce a rule often called the 50 percent rule. If repairs to a damaged home in a high-risk flood zone will cost 50 percent or more of the building's pre-damage market value, the home is considered "substantially damaged." At that point the whole building has to meet current flood requirements, which usually means getting the lowest floor up to the required elevation. We cover the details in our guide to the Treasure Island FEMA 50 percent rule.
The city building department makes the substantial damage determination. Each beach town handles the paperwork a little differently, so confirm the process with your city before you sign anything.
Option 1: Elevate the existing house
Elevating means a house mover and foundation crew lift the structure, build a new foundation underneath, and set it back down at the required height. On the barrier islands that new foundation is usually pilings or columns.
Elevation can make sense when:
- The framing is sound and the layout still works for you.
- The house is a simple shape that a mover can lift in one piece.
- You are attached to the character of the home or the lot setbacks it was grandfathered under.
It gets harder when the home is slab-on-grade block construction, has many additions built at different times, or has hidden rot and termite damage. Every lifted house also needs new stairs, new utility connections, and often a new driveway approach. Those items add up.
Option 2: Tear down and build new
Building new lets you design the home around today's codes from the start. That means a foundation made for the flood zone, a roof and windows built for the wind-borne debris rules, and space below the house planned for parking, storage and access. If that space interests you, read our post on flood vents, breakaway walls and enclosures.
A new build often makes sense when:
- The existing structure has major damage beyond the flooding.
- The floor plan no longer fits how you live.
- Lifting would mean reworking so much of the house that you are close to new construction anyway.
The trade-off is time. A new home goes through full design, engineering and plan review before construction starts. Our elevated home building page explains how that process works on the islands.
What drives the cost either way
We will not throw out ballpark numbers here, because every lot and house is different and a guess does more harm than good. These are the factors that move the price the most:
| Cost driver | Why it matters |
|---|---|
| Construction type | Wood frame homes are usually easier to lift than concrete block homes on a slab. |
| Required elevation | The higher the house has to go, the bigger the foundation and the longer the stairs. |
| Flood zone | V zones and Coastal A zones have stricter foundation rules than other A zones. |
| Soil and engineering | Piling depth and design depend on what the engineer finds on your lot. |
| Condition of the house | Hidden damage found after demo can change the plan. |
| Site access | Narrow streets and tight lots can limit equipment and staging. |
| Finishes and scope | A new build or a lift paired with a full remodel costs more than a basic lift. |
The honest way to compare is to get a site visit and pricing for both paths on your specific house.
Increased Cost of Compliance coverage
If you carry a flood policy through the NFIP, it includes a benefit called Increased Cost of Compliance, or ICC. As of 2026, FEMA says ICC provides up to $30,000 to help pay the cost of bringing a home into compliance with local floodplain rules after a flood.
According to FEMA, ICC can apply when:
- Your community determines the home is substantially damaged by flood, meaning repairs will cost 50 percent or more of its pre-damage market value.
- Or the home was flood damaged twice in 10 years and the repair costs averaged 25 percent or more of its market value, where your community's rules call for it.
FEMA lists four ways ICC money can be used: elevation, relocation, demolition, and floodproofing (that last one is for non-residential buildings only). FEMA also says the mitigation work has to be completed within six years of the date of loss, and that a partial advance is available once certain documents are in place.
Ask early. Call your flood insurance agent as soon as you learn the house is substantially damaged. Ask how ICC applies to your policy and to the option you are leaning toward, whether that is elevating or rebuilding.
This is general information, not legal or insurance advice. ICC limits and rules are set by FEMA and can change. Confirm current details with your flood insurance agent and your city's building department.
Permits and approvals
Both paths need permits. Expect some combination of these:
- A substantial damage determination from the city.
- A survey and an elevation certificate.
- Engineered foundation plans.
- Building permit review, plus zoning review for setbacks and height.
- Demolition permit if you are tearing down.
- Inspections during construction and a final elevation certificate.
Treasure Island, Madeira Beach, the Redingtons, St. Pete Beach and Indian Rocks Beach each run their own building departments. Check with yours for the exact submittal list.
Timeline factors
We cannot promise a schedule without seeing your project, but these things usually set the pace:
- How busy the building department is, especially after a storm.
- Engineering and survey turnaround.
- Availability of house movers and piling contractors.
- Utility disconnects and reconnects.
- Weather during hurricane season.
A lift often starts sooner because there is less design work. A new home takes longer up front but can move steadily once permits are in hand.
How to decide
Start with three questions. Is the structure worth saving? Does the layout still work for you? And once you add up the lift, the foundation and the repairs, how close are you to the cost of new? A contractor who does both kinds of work can walk the house with you and lay the options side by side. If you plan to keep the house and update the inside, our remodeling team can fold that into the plan.

Common questions
Can I just repair my flood-damaged home without raising it?
If the city determines the home is substantially damaged, it has to be brought up to current flood rules, which usually means elevating. If the damage is below that threshold, normal repairs may be allowed. Your city's building department makes that call.
How much does ICC coverage pay?
As of 2026, FEMA says Increased Cost of Compliance coverage on NFIP flood policies provides up to $30,000 toward elevation, relocation, demolition or floodproofing. Ask your flood insurance agent how it applies to your policy.
Is it cheaper to raise a house or build new?
It depends on the house. Construction type, required elevation, flood zone, soil, condition and finishes all change the math, so the best answer comes from pricing both options on your property.
