Johns Island is the large island south and west of West Ashley and James Island, across the Stono River. The City of Charleston covers part of it. The city’s City Plan counts 16 square miles in its Johns Island planning area and estimated 10,961 people there in 2019, up 108% from 2010, the fastest growth of any part of the city. It says growth trends point to about 2,000 more homes over 10 years, “developed at the lowest density of all city areas.”

Where it is

Maybank Highway (S.C. 700) and River Road are the main roads, with Bohicket Road to the south. The City Plan says most development on the island will happen inside the Urban Growth Boundary, an area “bounded approximately by Brownswood Road, Cane Slash Road, River Road and Bohicket Road,” concentrated at “three nodes of Maybank.” Inside that boundary, it says, existing development is 52% residential and 20% agricultural, and the industrial land is mostly the Charleston Executive Airport. Much of the island outside it is unincorporated Charleston County; check a parcel on Charleston County’s GIS Parcel Viewer.

Of the 1,487 points we checked inside the city limits, 99% were in ZIP code 29455, all in Charleston County. The city’s neighborhood council map lists five associations here: Headquarters Island, Rushland Plantation, Dunmovin/Island Estates, Winnsboro Lakes and Sea Island Place. The city’s Johns Island Restoration Plan looks at flood resiliency on the island.

Schools

We checked every point against Charleston County School District’s attendance boundaries in its school lookup tool (elementary zones for 2026-27, middle and high school zones for 2025-26).

The district’s map splits the elementary years between Angel Oak, for 4-year-old kindergarten through first grade, and Johns Island Elementary, for second through fifth grade. Angel Oak’s 2025 rating was for its earlier pre-K to fifth grade school; Johns Island Elementary has no 2025 report card. St. John’s High’s 2025 graduation rate was 92.5%. Ratings are the overall ratings on the state’s 2025 report cards. More in our schools guide.
