Mostly rural land with farms and historic settlement communities; about ten new subdivisions were planned and approved inside the urban growth boundary by 2007, and the population grew by half between 2000 and 2010.
We work across Johns Island rather than one corner of it — Red Top, Exchange Landing, Cape, Hut, Whaley, Stevens, Brownswood Place, Sea Island Place and Dunmovin/Island Estates included. Age and construction change between them, which is why we look before we quote.
Johns Island is the largest island in South Carolina, a rural sea island of farms, tree-lined roads and saltwater wetlands, home of the Angel Oak. About a third of it lies in the City of Charleston, which steers new subdivisions inside an urban growth boundary, while most of the island is unincorporated county land. City planning for the island calls for laying out new development around low-lying areas to avoid flooding.
Yes, on either side of the city line. Johns Island is split between the City of Charleston and unincorporated Charleston County. Inside city limits a re-roof needs the city's roofing permit and a final inspection; on county land, Charleston County Building Inspection Services (843-202-6930) issues the permit, and its code lists roofing among the work that needs one.
Johns Island enforces the 2021 IRC. The city and the county both enforce the 2021 South Carolina Residential Code (the 2021 International Residential Code with the state's changes).
The published number is 843-577-5550. The building official on record is Ken Granata, Chief Building Official (City of Charleston). The department page is here.
