An elevation certificate is a FEMA National Flood Insurance Program form that records a building's location, flood zone, and key elevations, such as the lowest floor, compared with the Base Flood Elevation. Insurers use it to rate flood policies, local building departments use it to confirm floodplain compliance, and it can support a FEMA map amendment request (LOMA).
You may need one if your property is in a high-risk flood zone (A or V zones), if you are building or substantially improving a structure there, or if you are applying for a LOMA. FEMA no longer requires one to buy flood insurance, but it may lower your premium. Ask your agent or lender what they require.
No. According to FEMA, a completed elevation certificate does not expire and remains valid after the home is sold. You will need a new one if the building is physically changed in a way that affects the recorded information, such as an addition, raised floor, or new equipment level. Your insurer may also prefer a newer form version.
A Letter of Map Amendment (LOMA) is an official FEMA determination that a property or building on natural ground sits above the Base Flood Elevation. If approved, the structure is removed from the high-risk flood zone, and your lender may no longer require flood insurance. Nexgen Logix can prepare the elevation data and LOMA application for you.
In Florida, a mortgage survey is a signed and sealed property survey ordered for a home purchase or refinance. It shows the property lines, buildings, fences, easements and any encroachments. Lenders and title insurers usually require a current survey so the title policy can cover survey matters instead of excluding them.
Florida law does not require a survey to close, but most lenders require one and title insurers rely on it. Without a survey, an owner's title policy usually keeps a standard survey exception, which removes coverage for the boundary and encroachment problems a survey would have shown. Ask your lender and title agent what they need.
Sometimes. On many residential sales, a title insurer will accept an older survey if the seller signs a survey affidavit stating that no buildings, fences, driveways or other improvements have been added since. It usually will not work if anything has changed, or if your lender requires a new survey certified to it by name.
An ALTA/NSPS Land Title Survey is a detailed boundary survey prepared to national standards adopted by the American Land Title Association and the National Society of Professional Surveyors. The current 2026 standards took effect February 23, 2026. Title insurers and lenders rely on it, mainly for commercial property, and optional Table A items add details they request.
Table A is a list of optional items in the ALTA/NSPS standards that a client, lender or title insurer can add to the basic survey, such as flood zone classification, land area, zoning information, utilities or parking. The survey request must say which Table A items to include, so get that list from your lender or title company first.
A boundary survey documents the perimeter of a parcel under Florida's Standards of Practice. An ALTA/NSPS Land Title Survey also meets the national ALTA/NSPS standards, which tie the survey to the title commitment and its recorded documents, such as easements, and add any Table A items the client requests. Title insurers rely on it to insure survey matters.
A boundary survey is a signed and sealed survey that documents the perimeter of a parcel by finding or setting its corners and boundary lines, as defined in Florida's Standards of Practice. It shows your property lines and how buildings, fences, driveways, pools and other improvements sit in relation to them.
You need a boundary survey whenever the location of a property line matters: buying with a lender or title company that asks for a current survey, building a fence, pool or addition near the line, applying for a permit that shows setbacks, settling a question with a neighbor, or splitting or selling part of a parcel.
A topographic survey measures selected natural and man-made features of a site and their horizontal and vertical relationships, as defined in Florida's Standards of Practice. It shows ground elevations, buildings, pavement, trees, drainage structures and visible utilities, so engineers, architects and builders can design with real numbers instead of estimates.
Topographic surveys are usually ordered at the start of design. Homeowners, builders, developers, engineers and architects use them to design a new home, addition, pool or commercial building, prepare a grading and drainage plan for a permit, plan a driveway, seawall or retaining wall, or check how water moves across a lot.
An update survey starts from an earlier boundary survey of the same property. The survey team checks the corners and existing improvements, shows anything that has changed since, such as a new fence, pool or addition, and then dates, signs, seals and certifies the drawing to the parties in your current transaction.
Update surveys suit owners who already have a professional boundary survey on file. They are common when selling or refinancing, when a lender or title company wants a survey certified to them, after adding a fence, pool or addition, or when a permit needs existing conditions. Your lender or title company decides whether an update is accepted.
An as-built survey is prepared after construction, or after a phase of construction, is complete. It locates the improvements that were built, such as a house, addition, pool, driveway, drainage structures, utilities or paving, and shows their position and, where required, their elevations relative to property lines and the approved design.
As-built surveys are requested near the end of a project. Builders, contractors, developers, engineers and owners use them to close out a permit or final inspection, confirm drainage, grading and paving were built as designed, document new utilities and structures, and support a certificate of occupancy. Requirements vary by city, county and agency.
When a builder sets up the wooden or metal forms for a slab or foundation, the forms show exactly where the building will sit and how high the floor will be. A form board survey locates those forms and measures their position relative to the property lines, along with the elevation of the top of the forms.
Builders, contractors and owner-builders order a form board survey after the forms are set and before concrete is poured. Building departments often require a survey during construction to confirm setbacks from property lines and easements and to check the planned finished floor elevation, including flood zone requirements where they apply. Check with your building department.
A spot survey, also called a foundation or slab survey, is prepared after the foundation or slab has been poured. It locates the finished foundation and shows its position relative to the property lines, along with the elevation of the slab where required.
Builders, contractors and owner-builders order a spot survey once the slab or foundation is in place. Building departments often require a survey during construction to confirm the foundation sits within the approved setbacks and the slab elevation meets the permit and flood zone requirements, so check with your building department about what it needs and when.
A final survey is a boundary survey prepared after construction is complete. It shows the finished building and site improvements, such as the house, driveway, walkways, pool, patio and fences, in relation to the property lines. Many building departments also ask for key elevations, such as the finished floor, so they can confirm the building was constructed as permitted.
A final survey is ordered when construction is finished or nearly finished. Builders and owners need one when the building department requires it for a certificate of occupancy, when closing on a newly built home, or when a lender or title company needs a survey of the completed property. Flood zone homes often need a finished construction elevation certificate too.
Building layout, also called construction staking, is the process of transferring a building's position from the approved site plan to the ground. The survey team sets stakes or marks at the building corners and other key points, measured from the property lines, so the builder knows exactly where to dig and set forms.
Builders, contractors, owner-builders and developers need layout and FFE staking at the start of construction, after the site is cleared and before forms are set. It places a new home, addition, pool or commercial building within the setbacks and marks the finished floor height required by the permit or flood zone.
Corner staking finds the corners of your property in the field and marks them so you can see the line on the ground. It is based on a boundary survey of the parcel, using the recorded legal description, plats and survey records. Missing or disturbed corners can be reset as part of the survey.
Corner staking helps anyone who needs to see the property line on the ground before work starts. Homeowners, fence and landscape contractors, builders and buyers of vacant land order it before installing a fence, wall or driveway, planning work near the lot edge, clearing land, or settling a question with a neighbor.
