Zoning, HOAs & Governance in Charleston, SC

1. Municipal government forms in South Carolina, confirmed city by city

South Carolina's 1975 Home Rule Act gives every incorporated municipality a choice of exactly three government forms, and -- like most states this site covers -- the choice genuinely varies place to place rather than holding uniformly across the state. Under Mayor-Council ("strong mayor"), an elected mayor serves as chief executive, supervising departments and appointing and removing employees, while council holds the legislative power and approves the mayor's budget. Under Council ("weak mayor"), council itself retains all legislative, policy, and administrative power; the mayor has no powers beyond any other council member unless council specifically delegates some, and a professional administrator, if council chooses to hire one, works at council's direction rather than as an independent executive. Under Council-Manager, council hires a professional manager who runs day-to-day administration as a distinct chief executive with no legislative role (Municipal Association of South Carolina).

All ten of this market's separately incorporated cities and towns had their form checked directly against the Municipal Association of South Carolina's own municipal directory. City of Charleston: Mayor-Council, with 12 councilmembers plus the mayor (13 total) elected from single-member districts; current mayor William Cogswell. City of North Charleston: Mayor-Council, 10 councilmembers plus the mayor (11 total), also single-member districts; current mayor Reggie Burgess. City of Folly Beach: Mayor-Council, 6 councilmembers at-large plus the mayor (7 total), with Aaron G. Pope serving as Manager/Administrator alongside the elected mayor. Town of Moncks Corner: Mayor-Council, 6 councilmembers at-large plus the mayor (7 total), Manager/Administrator Jeffrey Lord. City of Goose Creek: Mayor-Council, 7 councilmembers at-large plus the mayor (8 total), Manager/Administrator Natalie McKelvey Zeigler (MASC: Charleston; North Charleston; Folly Beach; Moncks Corner; Goose Creek).

Four more of this market's incorporated places run the Council ("weak mayor") form instead. Town of Mount Pleasant: Council, 8 councilmembers at-large plus the mayor (9 total); South Carolina's own definition of this form describes the mayor as "essentially a member of Town Council with extra duties" rather than an independent executive, and a 2019 council proposal to switch to a full-time, salaried strong-mayor form hadn't changed the town's form as of September 2026 (Post and Courier); day-to-day administration runs through Town Administrator Eric DeMoura (Berkeley-Charleston-Dorchester Council of Governments). Town of Summerville: Council, 6 councilmembers plus the mayor (7 total) from single-member districts, Manager/Administrator Scott Slatton. City of Hanahan: Council, 6 councilmembers at-large plus the mayor (7 total), City Manager/Administrator Courtney Soler. Town of Sullivan's Island: Council, 6 councilmembers at-large plus the mayor (7 total), Manager/Administrator Joseph R. Henderson (MASC: Mount Pleasant; Summerville; Hanahan; Sullivan's Island).

One more municipality in this market is worth a specific flag: the barrier-island guide covering Isle of Palms and Sullivan's Island actually spans two separate governments, and the first of them isn't a town at all. The City of Isle of Palms incorporated first as a town in 1938 and reincorporated as a city in 1957 (Wikipedia); it runs the Council form, 9 councilmembers at-large plus the mayor (10 total), Manager/Administrator Douglas Kerr (MASC: Isle of Palms) -- worth naming because general references sometimes describe it informally as "mayor-council" without distinguishing South Carolina's specific legal forms.

2. County government across Charleston, Berkeley & Dorchester counties

This market's three counties each organize their government differently under South Carolina law, and none of the three mirrors the others. Charleston County runs a Council-Administrator form: a nine-member County Council, elected from single-member districts to four-year terms, sets policy and appoints a professional County Administrator as the county's chief administrative officer (South Carolina Association of Counties). Berkeley County runs a Council-Supervisor form, a genuinely different hybrid: voters directly elect a County Supervisor to a four-year term, and that person serves simultaneously as chairman of County Council and as the county's chief administrative officer, casting the tiebreaking vote when council deadlocks (Berkeley County Government). Dorchester County runs a Council-Administrator form like Charleston County: County Council appoints a professional County Administrator to run day-to-day operations (Dorchester County Government).

What's consistent across all three, and worth naming because it cuts the other way from some states this site covers: South Carolina's County Sheriff is a directly elected constitutional office in every county (S.C. Code Title 23, Chapter 11), but the County Assessor — responsible for property valuations — is an appointed position rather than an elected one; a 2011-2012 state bill that would have made assessors elected officials didn't become law (South Carolina Legislature). Each county also maintains its own Register of Deeds office, the county's official real-property records office, where a homeowners association's declaration has to be recorded under the HOA Act described in Section 4.

In practice: a relocation to unincorporated land in any of these three counties means dealing with that county's own government directly for zoning and permitting, while a relocation to an address inside any of this market's ten incorporated cities and towns means dealing with that city's own government first (Section 1) and the county mainly for property assessment and recording.

3. Zoning: no single statewide code

Like most states this site covers, South Carolina has no single statewide zoning code. The state's Local Government Comprehensive Planning Enabling Act of 1994 (S.C. Code Title 6, Chapter 29) authorizes — but doesn't require — each municipality and county to create its own planning commission and adopt its own zoning ordinance tied to its own locally adopted comprehensive plan (S.C. Code §§6-29-320, 6-29-720). That means the zoning code that actually applies to a given parcel in this metro depends on which of the ten incorporated cities or towns it sits in, or, for unincorporated land, on which of the three counties it falls in — and, for a genuinely large share of this market's geography, on which side of an incorporation boundary that's shifted repeatedly over decades a specific parcel happens to fall (see Section 5, especially James Island and Johns Island).

Charleston's own zoning code is this metro's standout example of how far one city's ordinance can diverge from its neighbors'. The city passed the first historic-preservation zoning ordinance in the United States on October 19, 1931, creating both the city's Board of Architectural Review and the Old and Historic District that today protects more than 4,800 buildings across the peninsula (Preservation Society of Charleston). Any exterior change to a building inside that district needs the Board of Architectural Review's sign-off, on top of — not instead of — the ordinary zoning review every other property in the city goes through. No other municipality in this metro runs anything comparable in scale, though several run their own smaller local design-review rules for specific corridors (Section 5). Confirm a specific parcel's current zoning directly with the relevant city or county planning department.

4. HOAs in South Carolina: a dedicated statutory framework

South Carolina is genuinely different from some states this site covers in one respect worth naming plainly: rather than relying purely on each association's own recorded declaration under general nonprofit-corporation law, South Carolina maintains a dedicated statute specifically covering most homeowners associations — the Homeowners Association Act, S.C. Code Title 27, Chapter 30, which took effect May 17, 2018 (2018 Act No. 245). The Act requires an HOA's governing documents to be recorded in the county Register of Deeds office to remain enforceable, and applies retroactively: associations that already existed on the Act's effective date had to record their existing documents by January 10, 2019 (§27-30-130). It also requires an HOA to record any rule changes annually by January 10 and make current rules accessible to members by posting, email, or a website (§27-30-130); to give homeowners at least 48 hours' notice before a vote to raise the annual budget, with an exception for associations organized as nonprofit corporations (§27-30-140); to give homeowners inspection rights over budgets and membership lists (§27-30-150); and it gives magistrates courts concurrent jurisdiction over monetary HOA disputes (§27-30-160) (South Carolina Code of Laws). A separate, older statute, the Horizontal Property Act (S.C. Code Title 27, Chapter 31), covers condominiums specifically — the master deed, bylaws, and expense-allocation rules for a condominium regime rather than a single-family HOA subdivision (Justia).

HOA coverage varies sharply across this market's 14 guides, the same way it does in every metro this site covers. Mount Pleasant sits close to the "defined by its HOA" end of the range — most of the town's newer subdivisions, including I'On, are governed by a private homeowners association, and I'On's own HOA won a $1.75 million South Carolina Supreme Court judgment in a 2023 amenities dispute. Daniel Island runs on a single island-wide association, the Daniel Island Property Owners' Association (DIPOA), which administers design guidelines and covenants dating to the original Daniel Island Company master plan. Downtown Charleston's historic core sits at the other extreme: no private HOA governs it at all, because the Board of Architectural Review described in Section 3 predates the HOA model by decades and does that work instead. See Section 5 for the full place-by-place picture. As always, the actual recorded declaration for a specific property, not the general statute, governs the day-to-day rules — assessments, architectural review, rentals, short-term-rental restrictions — for that property.

5. Governance character, place by place

Five of this market's 14 guides cover places that were never separately incorporated as their own city or town at all — worth reading carefully before assuming a guide's name maps onto a single government the way it does for Charleston or Mount Pleasant.

"Split," "not incorporated," and "annexed" above describe boundaries that have moved before and can move again — confirm current jurisdiction for a specific parcel directly with the relevant city or county before relying on it.

6. Where to check a specific address

• Any of this market's ten incorporated cities and towns: that city or town's own Planning & Zoning, Community Development, or Building & Zoning department
• Unincorporated land in Charleston, Berkeley, or Dorchester County: that county's own planning department
• Any address's HOA status or recorded declaration: the relevant county's Register of Deeds office (Section 2)
• A parcel near a jurisdiction boundary (Section 5 has several): the relevant county's GIS or tax-map office can confirm which government actually covers it, before you call the wrong planning department
• Property assessment and county government generally: the relevant county Assessor and County Council

7. How we keep this page current

Municipal government forms in Section 1 reflect a direct check against the Municipal Association of South Carolina's own directory, current for all ten of this market's incorporated cities and towns as of September 2026. County government structure in Section 2 reflects each county's own government website. Named office-holders (mayors, administrators, county council members) turn over on their own election and hiring cycles regardless — treat any individual named on this page as a point-in-time reference, not a permanent fact. The incorporation history in Section 5, especially for James Island and Johns Island, draws on South Carolina Supreme Court records and contemporaneous news coverage rather than a single source, given how genuinely contested that history has been — and it isn't necessarily finished: both James Island and the City of Charleston were still pursuing new annexations as of late 2025, and a prior push to incorporate Johns Island on its own hasn't been confirmed as either resolved or abandoned.
