In an emergency, seconds count so it's crucial that your home or business can be easily located.
So a multi-year project is underway in Martin County to make sure crews can get to you as quickly as possible.
When they're not out fighting fires, Firefighter/EMTs Jeff Eller and Lauren O'Loughlin are taking part in a time consuming project now designed to save time later.
"Green means it meets all the codes, red means it doesn't for some reason or another," says Eller as they drive through a Jensen Beach neighborhood.
Working with the Property Appraiser's office, they are reviewing addresses throughout unincorporated Martin County.
Working with a laser pointer, they are determining if homes in a neighborhood are properly identified.
Homes within 50 feet of the road need easily seen numbers on the structure. If the house is more than 50 feet from the road, there still needs to be numerical identification out at the street.
Right now, 13% or close to one in 7 addresses doesn't match up with the county data base.
"One of those databases is our "CAD" system, our Computer Aided Dispatch system where we dispatch our fire-rescue or our sheriffs'," says Martin County IT Director Denise Eldredge.
Eldredge says an estimated 30 percent of all homes and businesses may be in some sort of violation.
Martin County Fire-Rescue Division Chief Dan Wouters says this project should help cut back on response time.
"So that when a 911 call comes in, we know exactly where that location is and where we're responding to," says Chief Wouters.
This project should take anywhere from three to five years to complete.
People and businesses that need to update their numbers will get 90 days to do so.
It's Denise Eldridge's job to help coordinate all the data that will be coming in.
"There is a 30 percent discrepancy we're seeing right now where we have no number on the home," said Denise.
