The unincorporated Census-Designated Place along SR-13 — RiverTown, Aberdeen, and a network of mid-corridor sub-neighborhoods that all share the same ZIP.
The St. Johns CDP address prefix covers many communities. Ask us for the exact ZIP-level breakdown for the sub-neighborhood you're considering.
When you search for "St. Johns, FL homes" you'll see a lot of results, and they will not all be in the same place. St. Johns is an unincorporated Census-Designated Place centered on the SR-13 corridor in northern St. Johns County (ZIP 32259). It is not a chartered city, does not have its own municipal government, and does not have city limits. The Census draws the CDP boundary primarily for statistical purposes.
What that means for a buyer: the "St. Johns" address prefix touches many different communities. Some are large master-planned developments like RiverTown and Aberdeen. Others are established SR-13-corridor sub-neighborhoods. Others are newer infill inside older shells. Two houses with "St. Johns, FL" mailing addresses can be in entirely different price bands and school zones.
This page is our meta-guide to what St. Johns really means, plus a deeper look at RiverTown — the largest single new-construction master plan inside the CDP.
RiverTown is the largest single community carrying the St. Johns address prefix. Here is what a buyer should know.
Mattamy Homes' original core village. Multi-plan single-family lineup, mid-corridor amenity access, and the community's Freedom Crossing Academy K-8 on-site.
Newer sections added as the master plan expanded. Multi-builder lineup with a range of price points and plans.
Homes with direct or near-direct St. Johns River frontage on the western side of RiverTown. Riverfront park access and boat access.
Townhome sections from multiple builders. The lowest entry-point with the same school zoning and amenity access.
Because the St. Johns CDP covers a big area, elementary/middle/high assignment depends heavily on exact address. Broadly:
All zoning is by address. We verify current assignment on every offer — the difference between a Creekside- and a Bartram Trail-zoned house can affect resale, and both are among the top high schools in Florida's #1-ranked district.
RiverTown is a Community Development District (CDD); Aberdeen and most mid-corridor established sub-neighborhoods are HOA-only. On a $550,000 RiverTown home with homestead, budget roughly $4,200–$4,500 in ad valorem tax plus $1,800–$3,000 in CDD, for a total annual carrying cost around $6,300–$7,800 before HOA and insurance. On a similar-priced Aberdeen or mid-corridor HOA-only home, expect a total closer to $4,500–$5,200. That difference is real and shows up every month.
We disclose the exact CDD, HOA, and expected insurance range on every home before you write.
Off-peak. Rush hour on SR-13 or I-295 near Race Track Rd can add 15–25 minutes each way.
No. St. Johns is an unincorporated Census-Designated Place along SR-13 in northern St. Johns County (ZIP 32259). It has no city government or city limits. The "St. Johns, FL" address prefix touches many communities.
RiverTown is Mattamy Homes' 4,200-acre master-planned community on the St. Johns River in the SR-13 corridor. Multiple builders (Mattamy, KB Home, Dream Finders, and others) operate villages inside it. The community has a Freedom Crossing Academy K-8 school on-site, an amenity center (RiverHouse), a riverfront park with boat access, and a growing town-center footprint. Zoned to Bartram Trail High School.
Zoning varies widely by address. RiverTown addresses are generally Freedom Crossing Academy K-8 and Bartram Trail High; Aberdeen is Cunningham Creek Elementary / Switzerland Point Middle / Bartram Trail High; mid-corridor addresses can be Creekside High if closer to Fruit Cove. Always verify by address — we run the school-locator check on every home.
Because the CDP covers different communities, the price band is wide. RiverTown new construction generally runs $430,000–$800,000; Aberdeen resale $400,000–$700,000; other mid-corridor sub-neighborhoods vary. Townhomes fall below the range; St. Johns River waterfront homes can exceed $1,000,000.
RiverTown is on the St. Johns River with a Bartram Trail High feeder; Silverleaf is west of I-95 near St. Augustine with a Tocoi Creek High feeder; Nocatee is at the northern edge of the county with a Palm Valley / Nease feeder. All three are strong SJCSD zonings with CDDs and multi-builder lineups; they differ in commute, amenity, and school assignment. We help buyers cross-compare on the numbers that matter.
