Your flood insurance premium went up again. Maybe it doubled. Maybe it tripled. And now you are wondering if the house you love is still worth keeping.
You are not alone. Thousands of homeowners along Long Island’s South Shore, canal communities, and barrier island towns face the same decision. A house lift might be the answer, but most homeowners have never been through the process.
This guide covers everything you need to know about house lifts on Long Island: the real costs, the process, the insurance math, and how to decide if raising your home makes financial sense.
Why Long Island Homeowners Are Raising Their Homes
After Superstorm Sandy devastated coastal neighborhoods in 2012, FEMA redrew flood maps across Nassau and Suffolk counties. Homes that were never in a flood zone suddenly were. Homes already in zones saw base flood elevations increase by several feet.
The financial impact has been brutal. Homeowners in high-risk zones can pay $3,000 to $ 5,000 or more per year for flood insurance. Over a 20-year mortgage, that is $60,000 to $100,000 in insurance alone. FEMA’s Risk Rating 2.0 system has pushed premiums even higher based on individual property risk.
Raising your home above the base flood elevation is one of the most effective ways to cut that burden. Data from HomeGuide shows that lifting a house can reduce flood insurance by 30% to 60% and increase resale value by 15% to 25%.
How a House Lift Actually Works
House lifting sounds dramatic: your entire home is lifted off its foundation while a new foundation is built underneath. But the process is more methodical than most homeowners expect.
- Engineering assessment. A structural engineer evaluates your frame, foundation, and soil conditions to determine if pilings are needed.
- Elevation survey. A licensed surveyor compares your current elevation to FEMA’s base flood elevation to determine how high the House needs to go.
- Permits and foundation design. Your contractor files permits and designs the new foundation, concrete block, poured concrete, or pilings.
- Utility disconnection. Water, gas, electric, and sewer lines are disconnected.
- The lift. Steel beams are inserted through the existing foundation. Synchronized hydraulic jacks raise the home evenly to prevent cracking.
- New foundation. While elevated, the new foundation is built and cured beneath the home.
- Lowering and restoration. The home is set onto the new foundation. Utilities reconnect. Stairs, porches, and landscaping are rebuilt.
The full process typically takes 3 to 6 months. The home is elevated for roughly 4 to 8 weeks during foundation work.
What Does a House Lift Cost on Long Island?
Costs vary widely based on home size, foundation type, lift height, and soil conditions. Here are realistic ranges for Long Island in 2026:
- Elevation only (lift the structure, no foundation work): $10,000 to $40,000
- Lift with new foundation (most common scope): $40,000 to $150,000
- Full turn-key project (lift, foundation, utility reconnection, stairs, landscaping, exterior restoration): $80,000 to $250,000+
Larger homes, brick exteriors, attached garages, and challenging soil push costs higher. Homes requiring deep pilings in coastal zones cost more than those on standard footings.
These numbers do not include interior renovations. Many homeowners renovate the interior at the same time since utilities are already disconnected. Combining a lift with a gut renovation is often more cost-effective than doing them separately.
Flood Insurance Savings: The Math That Makes It Work
If you are paying $4,500 per year in flood insurance and a house lift cuts that by 50%, you save $2,250 annually. Over 20 years, that is $45,000 before accounting for the premium increases you avoided.
FEMA allows reductions for every foot above the base flood elevation. Some Long Island homeowners have seen insurance drop from $5,000+ to under $1,500 after elevating. Add the 15% to 25% property value increase, and the ROI often exceeds the cost of the lift within 10 to 15 years.
Financial Assistance Available on Long Island
You may not have to fund the entire project out of pocket.
- ICC Grant (Increased Cost of Compliance). If your home was declared substantially damaged, or if flood damage exceeded 50% of pre-storm value, your flood insurance may reimburse up to $30,000 toward elevation costs.
- NY State Plus-One ADU Program. Some East Hampton homeowners have accessed up to $125,000 in grants for qualifying properties.
- Local municipal programs. Several Long Island towns have offered elevation incentives or expedited permitting for homeowners in high-risk flood zones. Contact your town hall directly.
A contractor experienced with house lifts should know which programs apply and help you navigate applications.
How to Know If a House Lift Is Right for You
Not every home is a candidate. Consider these factors:
- Your current elevation vs. the BFE. If your lowest floor sits several feet below the base flood elevation, insurance savings alone may justify the project.
- Foundation condition. A compromised foundation makes the lift an opportunity to replace it entirely.
- Long-term plans. If you plan to stay 10+ years, the investment math works strongly in your favor.
- Emotional attachment. Many Long Island canal homeowners have lived in their neighborhoods for decades. Raising the home lets you stay without the financial risk.
The first step is a professional assessment, not a sales pitch. A real evaluation of your flood risk, elevation, and the financial case for lifting.

Frequently Asked Questions
How high do I need to raise my house on Long Island?
FEMA requires your lowest living floor to meet the base flood elevation for your zone. New York State adds two feet above that. Each additional foot above the requirement can further reduce your flood insurance premium.
Can I live in my house during a house lift?
No. You must vacate during the lift and foundation work, typically 4 to 8 weeks. Utilities are disconnected throughout this phase. Plan for temporary housing during that period.
Do I need permits to raise my house on Long Island?
Yes, house lifts require building permits from your local town, Brookhaven, Islip, Babylon, Hempstead, or whichever municipality you are in. A full-service contractor handles all permitting and inspections.
Will raising my house increase its resale value?
Yes. Elevated homes in flood zones typically see a 15% to 25% increase in property value. Buyers pay a premium for homes with lower flood risk and reduced insurance costs.
