Street designations are defined in the addressing Ordinance 2019-47 in Section 90.2 and must fit the criteria outlined therein.

Changing your address could result in a delay in the online mapping process, as our office provides updated address and street information to Google Maps and ESRI Maps on a consistent basis. The online mapping systems utilized by delivery services or other vendors are beyond our control, and we cannot determine or guarantee the schedule for their data updates.

There are a number of reasons your property may require re-addressing. The street name may have changed, your address number may be out of sequence with the established grid, you may be an odd number on the even side of the street or the driveway to access your property has changed.

Depending upon if it is residential or commercial, Seminole County Addressing Staff will notify the Post Office, Sheriff's Department, E911 Administration, Fire Department, Utilities- Water, Power, Phone, County Solid Waste Office, Supervisor of Elections Office, School Board, Teleatlas, Owner and/or Developer.

For unincorporated county, Addressing is a reviewer for all new construction permits and addresses are assigned in conjunction with a building permit. Addresses are released once a permit is issued.
