House Lifting in Tampa Bay: Your Questions Answered
Considering elevating your home? Start with whether lifting makes sense for your property, then work through the cost, design, contractor selection, and construction process.
01Is House Lifting Right for My Home?
What does it mean to lift or elevate a house?
House lifting is the process of raising an existing building and supporting it at a higher elevation on an engineered permanent foundation.
The structure is temporarily supported during lifting and foundation construction, then transferred onto its permanent supports. Depending on the design, portions of the existing foundation may be retained, modified, or replaced.
The physical lift is only one phase of the project. It is not the same as completing the permanent foundation, reconnecting utilities, or making the home ready for occupancy.
Why would I elevate my existing home instead of demolishing and rebuilding?
Consider elevation when the existing home is worth preserving and you want to retain its layout, architectural character, or improvements while reducing its exposure to flooding.
The decision should compare the complete elevation project with the complete rebuilding project, including necessary repairs, desired renovations, temporary housing, and the condition of the existing structure.
Lifting is not automatically the better choice. Extensive deterioration, structural deficiencies, difficult access, or major renovation needs may make rebuilding worth serious consideration. A property evaluation should come before choosing either direction.
Can a slab on grade home actually be lifted?
Yes. A home built on a concrete slab can often be elevated with the existing slab remaining with the structure.
The project requires an engineered support system capable of carrying the slab, walls, and other building loads during lifting and after permanent support is installed. A slab originally supported by soil cannot simply be assumed to function as an elevated structural floor without appropriate support.
Slab thickness, reinforcement, condition, existing footings, building configuration, and access all affect the lifting and permanent support design.
Can concrete block, brick, and wood framed homes be lifted?
Yes. Many wood framed, concrete block, and brick or brick veneer homes can be lifted. The construction type affects the lifting method, structural support requirements, weight, and cost.
Masonry walls, brick veneer, chimneys, fireplaces, and other heavy or brittle components require particular attention. Their condition and connection to the main structure must be evaluated.
The ability to lift a home does not mean every attached component can remain untouched or that cracking can be ruled out. Those conditions should be addressed during planning.
What happens to additions, garages, porches, sunrooms, and areas with different floor elevations?
Each building portion must be evaluated separately. The plans and scope should identify whether it will be lifted with the main home, separated and left at its existing elevation, demolished, or reconstructed.
A shared wall or connected roof does not automatically mean an addition has the same foundation or can be lifted in the same manner.
Homes with multiple floor elevations or additions may require additional steel, separation work, temporary support, or reconstruction. Every included and excluded building portion should be clearly identified before construction begins.
02What Will It Cost, and How Can I Pay for It?
How much does it cost to elevate a home?
There is no reliable universal price that applies to every home.
Cost depends on the building’s footprint, construction type, condition, configuration, required elevation, access, soil conditions, foundation design, and included improvements.
Square footage is a starting point, but two homes of the same size can have substantially different requirements. A straightforward rectangular home may require a different support system than one with numerous additions, corners, concentrated loads, or restricted access.
The most useful estimate is tied to a clearly defined scope and clearly stated assumptions, not just a price per square foot.
What additional expenses should I budget for beyond the house lifting contract?
Depending on the agreement, additional expenses may include temporary housing, storage, utility modifications, replacement of deteriorated components, stairs and landings, accessibility equipment, finish repairs, and restoration of disturbed site improvements.
Some of these items may already be included in the construction contract. Others may be excluded or priced as options. The distinction must be clear.
A useful overall budget separates the contracted construction price from owner expenses, optional improvements, allowances, and a contingency for conditions that cannot reasonably be confirmed before construction.
Is the price fixed, and why can the initial estimate change after engineering?
A preliminary estimate and a finalized project budget are not the same thing.
Initial pricing may rely on assumptions about steel, foundations, pile depths, utilities, and existing conditions. Engineering and permitting establish the actual requirements, which may differ from those initial assumptions.
JAS’s proposal process provides for reviewing the estimate against the engineered and permitted project. Once the defined project budget is established, the price remains fixed except for written change orders and other adjustments expressly authorized by the agreement.
Calling an amount a “project budget” does not, by itself, make the agreement an open ended cost plus contract.
What payment schedule should I expect?
The payment schedule should identify clear milestones and account for planning, procurement, equipment, and construction commitments.
The agreement should explain when each payment becomes due and what constitutes completion of the applicable milestone. Completing the initial lift, completing the permanent supports, and completing the overall project are separate events.
Before signing, review payment requirements alongside the scope and schedule. Address any dependence on lender draws, insurance proceeds, or grant funding expressly rather than assuming those funding timelines automatically control when contract payments are due.
Are grants, FEMA assistance, or other funding programs available?
Yes. Depending on your location, storm damage, income and property eligibility, assistance may be available through local recovery programs or flood insurance. Program limits are maximums, not guaranteed awards.

Qualifying NFIP policyholders may receive up to $30,000 in Increased Cost of Compliance coverage. This is a conditional insurance benefit, not an automatic grant. My Safe Florida Home separately offers potential funding for approved wind protection improvements, not house lifting.
Check the official program before starting work that depends on assistance. Eligibility, contractor selection, owner contributions and repayment conditions vary. Funding approval does not automatically authorize construction or change your obligations under a JAS agreement.
Explore funding programs by county →Will elevating my home reduce flood insurance costs or increase its value?
Elevation can improve a home’s flood risk profile, but a specific insurance reduction should not be promised. Flood insurance pricing considers multiple property characteristics, including first floor height, foundation type, location, and other risk factors.
Ask your insurance professional to evaluate the proposed design and estimate the effect on your particular policy. Raising the building does not automatically change the property’s mapped flood zone. Any map change requires a separate process.
For resale planning, obtain a local market assessment rather than assuming a guaranteed increase in value or return on construction cost. Also confirm any continuing insurance requirements directly with your lender.
Will elevating my home increase my property taxes?
The answer depends on the property’s circumstances and the applicable assessment rules.
Florida’s calamity provisions can preserve certain assessment protections for qualifying damaged properties that are repaired, elevated, or rebuilt. Homestead status, added area, the nature of the work, and construction timing can affect the treatment.
Those protections are not a blanket promise that every elevation project will leave the tax bill unchanged. Ask the county property appraiser to evaluate the proposed work before relying on a particular tax outcome.
03What Will My Elevated Home Look Like?
How is the required elevation determined, and what do BFE and DFE mean?
Base flood elevation, or BFE, is the calculated water surface elevation associated with a flood having a 1% annual chance of being equaled or exceeded. It is not a guarantee that future flooding will stay below that level.
Design flood elevation, or DFE, is the flood elevation adopted for design. Applicable building codes and local floodplain requirements establish the required building elevation, including any additional height known as freeboard. Depending on the flood zone and applicable requirements, the controlling measurement may be the finished floor or the bottom of the lowest horizontal structural member.
These measurements use a survey reference datum. A required elevation of 12 feet does not necessarily mean the house must be raised 12 feet. The actual lift depends on the existing elevation and approved design.
Can I raise my home higher than the minimum requirement?
Often, but the proposed height must comply with applicable zoning, building, floodplain, and structural requirements.
Additional height can affect structural demands, connections, stairs, accessibility, utilities, and cost. It is not necessarily just a matter of making the piers taller.
The appropriate elevation should balance flood protection, permitted building height, desired clearance beneath the home, practical access, and budget. Make that decision before the structural design is finalized.
Can I enclose the area beneath my home or use it as living space?
Where floodplain rules restrict the area below the required elevation, permitted uses are generally limited to parking, building access, and compliant storage.
That space is not automatically available for a bedroom, office, apartment, or other habitable room.
Enclosures may require flood openings, flood damage resistant materials, and limitations on equipment and finishes. In coastal conditions, open foundations and nonstructural breakaway walls may be required. Local requirements may impose additional restrictions.
An enclosed garage beneath an elevated home is not the same as approved living space. Flood openings and breakaway walls also do not make the enclosure waterproof.
Are new stairs, decks, and landings automatically included?
No. The proposal should expressly identify whether stairs, decks, landings, railings, and their foundations are included.
It should also state quantities, dimensions, materials, and finishes. A basic access stair is not the same scope as a large deck, multiple stair systems, or an architectural entrance.
Required safe access must still be provided before occupancy is authorized. When access construction is excluded from JAS’s scope, responsibility for its design, permitting, and completion should be assigned before work begins.
Can an elevator or residential lift be added?
Often, but it should be evaluated during design rather than treated as an afterthought.
An elevator or residential lift may require additional foundation support, structural framing, landings, electrical service, an enclosure or shaft, and flood protection measures. Equipment selection affects space requirements and the work needed to install it.
The equipment purchase price is only one part of the installed cost. Ask for the complete scope, including associated construction, permitting, electrical work, and finishes. Do not assume accessibility equipment is included in a house lifting proposal.
What design decisions should I make before construction begins?
Resolve the final elevation, which building portions will remain, stair and deck locations, intended use beneath the home, vehicle clearance, equipment locations, and any planned elevator or residential lift.
These decisions affect structural supports, access, utilities, and permitting.
For parking or storage beneath the home, consider the clearance below the lowest obstruction, which may be a structural beam rather than the elevated floor. Changing these decisions after steel fabrication or foundation construction can require revised plans and additional work.
04How Do I Choose the Right Contractor?
Should I hire a general contractor, a structural lifting company, or both?
A complete elevation project requires both construction coordination and specialized lifting capability.
A lifting contractor’s agreement may cover only raising, temporarily supporting, and setting down the building. Engineering, permanent foundations, utilities, stairs, inspections, and project closeout still need clearly assigned responsibility.
JAS can serve as the general contractor for the agreed project scope and coordinate the specialized work. Before hiring anyone, verify appropriate licensing, relevant experience with comparable structures, insurance, and responsibility for each phase.
A lifting contract is not necessarily a contract to deliver a completed, occupiable home.
Does JAS handle only the lift, or can JAS manage the entire project?
JAS can provide a defined structural lifting scope or manage a broader elevation and construction project, depending on the agreement.
A broader project may include engineering and permitting coordination, foundation construction, utilities, stairs, decks, renovations, and other selected improvements. However, those services are not automatically included simply because JAS can perform or manage them.
Only work expressly identified as included in the signed scope is included. Anything not expressly included is excluded unless added by written agreement.
How should I compare proposals from different contractors?
Compare the complete scope, not just the total price.
Determine whether each proposal includes engineering, permits, excavation, lifting, temporary support, final set down, permanent steel, foundations, piles, utilities, stairs, inspections, and closeout documentation. Compare allowances, assumed pile depths, exclusions, and responsibility for repairs and restoration.
A lift only proposal cannot fairly be compared with a proposal that includes the permanent foundation and related construction.
Work can be excluded from a contractor’s price and still be required to finish the project. Identify who will perform and pay for that work before construction begins.
What insurance should be confirmed before the lift?
Do not assume a standard homeowners policy or a contractor’s general liability policy covers every exposure associated with lifting an existing building.
Obtain written confirmation from the appropriate insurance professional addressing the existing structure during lifting, temporary support, set down, and construction. Clarify applicable wind, flood, collapse, theft, and vandalism coverage, along with exclusions, vacancy restrictions, and deductibles.
A generic certificate of insurance is not necessarily confirmation that the specific lifting operation is covered. The agreement should identify the coverage each party is responsible for maintaining.
05What Happens Before Construction Begins?
What should I do first, and what documents should I gather?
Start with your property address, your reasons for elevating, and a description of what you want the completed project to accomplish.
Gather any available survey, Elevation Certificate, building plans, geotechnical report, and records of previous additions or structural repairs. Disclose known damage, settlement, utility problems, and undocumented alterations.
Also provide any substantial damage determination or relevant correspondence from the building department. These documents help establish what must be evaluated before developing the design and budget. You do not need every document in hand to begin an initial discussion.
How does the FEMA 50 percent rule affect an elevation or renovation project?
Under the National Flood Insurance Program’s minimum standards, a building in a Special Flood Hazard Area generally must meet applicable floodplain requirements when proposed improvements equal or exceed 50% of the building’s market value before the improvement, or when restoring damage would reach that threshold based on the building’s value before the damage.
The calculation concerns the building, not the land. Substantial damage is based on the cost to restore the building to its condition before the damage, not simply the insurance payment or the repairs the owner chooses to perform. The local jurisdiction makes the determination and may apply a lower percentage threshold.
Florida law now prohibits participating local governments from enforcing a cumulative substantial improvement period. That does not eliminate the underlying substantial improvement or substantial damage review. Older explanations of multiyear accumulation rules should not be relied upon without checking current requirements.
What does the engineering and permitting process involve?
The process generally includes documenting existing conditions, establishing the required elevation, evaluating the structure and soils, preparing the lifting and permanent foundation design, coordinating related improvements, and obtaining required approvals.
Depending on the property, reviews may involve building, zoning, floodplain, site development, and utility requirements.
Engineering must address both the completed structure and the construction sequence. A design that works after completion must also allow the home to be supported during construction and the temporary lifting equipment to be safely removed.
How long does the entire project take, including engineering, permitting, and construction?
Plan for a process measured in months, not just the time required to operate the lifting equipment.
Engineering and permitting can take several months, followed by several months of construction, depending on the property and scope. The physical raising operation is only one milestone.
Design revisions, permit reviews, utility coordination, concealed conditions, foundation work, inspections, weather, and owner decisions can affect the schedule. Project scheduling should distinguish preconstruction, active construction, and final approvals rather than treating “the house is lifted” as the completion date.
How are changes, additional requirements, and concealed conditions handled?
The agreement should establish a written process for documenting changes, pricing them, and identifying schedule impacts.
A change order should describe the added, deleted, or revised work and state the price or agreed pricing method. Changes affecting structural work may also require revised engineering and permit approval before the affected construction proceeds.
When concealed conditions differ from the approved assumptions, the responsible professionals must determine the appropriate response. Emergency protective work may require separate treatment under the agreement, but ordinary scope changes should not depend on informal conversations or conflicting plan sets.
