Getting started with the Longwood GIS map

Opening the official parcel viewer
Begin with the Seminole County parcel viewer; it covers each assessed parcel around Sanford and Altamonte Springs. For property near Oviedo, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Near Lake Mary, write down the parcel ID before closing the panel; every office in the county asks for it first.
Getting your bearings
Sanford serves as the county seat, which is where the courthouse records live. Smaller places on the map include Casselberry, Altamonte Springs, Lake Mary, and Winter Springs. Roughly 484,271 people live in Seminole County (Census estimate, 2023) spread over roughly 309 square miles. Seminole County was organized in 1913, and some chains of title near Oviedo are long.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the Clerk of the Circuit Court (official records); the parcel map near Altamonte Springs only summarizes it. Long-held tracts near Lake Mary can sit on a long string of deeds, so a title company earns its fee on a real sale.
