- ✓They fill out the official FEMA Elevation Certificate rather than a made-up form of their own.
- ✓They will explain what the finished floor height means for your flood zone without promising a lower insurance bill in advance.
- ✓They keep the flood map data they used on file, so the certificate can be updated if the maps change later.

Common questions
What is a Flood Elevation Certificate?
It is an official FEMA form that shows how high your building sits compared to the expected flood level for your area. A licensed surveyor measures your floor heights, checks the flood map, and records the numbers on the form. Insurance companies and floodplain offices use it to see how much flood risk a building really has.
Who is allowed to sign an Elevation Certificate in Texas?
In Texas the form must be prepared and sealed by a Registered Professional Land Surveyor or a licensed professional engineer. A general contractor or an insurance agent cannot sign it. When you call around, ask that the person doing the work holds a current Texas RPLS or PE license.
Why would I need one?
The most common reasons are flood insurance and permits. Your insurance company may ask for one to set your rate, a city or county may require one before you build or remodel near water, and you may want one to ask FEMA to change your flood zone. Lenders and buyers sometimes ask for it during a home sale too.
Can an Elevation Certificate lower my flood insurance?
Sometimes, but there is no promise. If the survey shows your floor sits higher than the map assumes, your insurer may offer a better rate. If it sits lower, the certificate could show more risk. It is an honest measurement, so the result depends on your actual building and lot.
How long is a certificate good for?
There is no fixed expiration date on the form itself, but it can become out of date. If the flood maps for your area are updated, or you raise, remodel, or add on to the building, you may need a new one. Ask your insurer or floodplain office whether the date on your certificate is still accepted.
What should I have ready before the surveyor arrives?
It helps to have your property address, any old survey or certificate you already have, and clear access to the building, crawl space, and any flood vents. Let the surveyor know if you are working toward flood insurance, a permit, or a map change, because that can affect how the form is filled out.
What is the difference between an Elevation Certificate and a regular property survey?
A regular boundary survey shows where your property lines are. An Elevation Certificate is about height. It records how high your floors sit relative to the flood level and is written on the specific FEMA form. Some surveyors do both, so it is fine to ask if you need each one.
