Moving to St. Johns County: what to know before you pick a corridor.

St. Johns County is a long rectangle between the Atlantic and the St. Johns River, with St. Augustine as the county seat at its southern end and Ponte Vedra Beach at the northern tip. Almost everything in between is unincorporated county, which is why so many addresses say "St. Augustine" or "Ponte Vedra" for homes that are nowhere near either. Buyers who search by city name miss most of the inventory.

The practical map is corridors, not cities. The coast runs Ponte Vedra Beach, Nocatee, Vilano, St. Augustine and the beaches south of it. The CR-210 corridor and Julington Creek sit along the Duval line for Jacksonville commuters. World Golf Village, Palencia and the newer master-planned communities fill the middle along I-95 and US-1. RiverTown and SilverLeaf anchor the west side toward the river. Each corridor has its own price band, builder era and commute, and the page for each is linked below.

The county grew around master-planned communities, and most of the homes built in the last twenty years sit inside one. That means amenity centers, trail systems and events calendars, and it also means Community Development District assessments on the tax bill that fund them. Which communities carry a CDD, and roughly what it does to a payment, is on the county CDD page linked below; the live table on each community page shows the HOA side.

Outside the master plans, the older neighborhoods along the coast and around downtown St. Augustine run on a different logic: fewer shared amenities, more character, older roofs and older insurance questions. I show both kinds every week, and the right answer depends on how you want to spend a Saturday.

Florida has no state income tax, and that is usually the first reason people call. The lines that replace it are property tax at your purchase price (the previous owner’s bill tells you nothing, because the Save Our Homes cap resets on sale), homeowner’s insurance that varies more by roof age and construction than by price, and any CDD or HOA the community carries. I lay all of those out on the true monthly cost section of every listing on this site, and the tax-math page linked below walks the state-to-state comparison.

Most St. Johns County households work somewhere else. I-95 and US-1 carry the county to Jacksonville’s Southside and downtown, 9B connects the northern corridors to the Southside employers, and A1A serves the coast. The northern corridors are a daily commute for many Jacksonville workers; from the St. Augustine end it is a longer proposition that people accept for the lifestyle. Before you commit to a corridor, drive it at the hour you would actually drive it. I will tell you which junctions pinch and when.

St. Johns County runs one county-wide public school district, and homes are assigned to schools by attendance zone, which the district revises as it builds. Two houses on the same street can zone differently after a boundary change. The zoning is a fact to verify for the specific address before you write an offer, not a reputation to buy on. My school pages show the homes currently zoned to each school so you can start from the school and work back to the house.
