The house is yours. The outside of it, in a Charleston historic district, is a shared decision with a city board. That surprises people, and it should be part of the purchase, not a discovery six months later when you try to swap the windows and learn you need approval first.
None of this is a reason to avoid a historic home. It is a reason to know exactly what you are buying, because "I'll just renovate it" means something very specific downtown.
Meet the BAR
Charleston created the nation's first local historic district and the first Board of Architectural Review in 1931, the first preservation ordinance in the country. The BAR reviews the exterior appearance of buildings in the historic districts. It cannot touch your interior layout. What it does control on a visible exterior is broad: height, scale, mass, materials, windows, doors, and more. Its approval is a Certificate of Appropriateness, and here is the key: a Certificate of Appropriateness is a precondition to a building permit, not the permit itself. You get the BAR's blessing first, then you apply for the permit.
Three districts, and don't confuse the boards
There are actually three historic districts, not one: the Old and Historic District (the strictest, covering any exterior change visible from the public right-of-way, with no building-age cutoff), the Old City District, and the Historic Corridor District (where review triggers are tied to a building's age). The BAR also covers individual Landmark Overlay properties. And do not confuse the BAR with the Design Review Board (DRB): the DRB reviews properties outside the historic districts. Which board, and which rules, depends entirely on where the address sits.
What needs approval before you touch it
Inside the Old and Historic District, a Certificate of Appropriateness is required for new construction, demolition (in whole or in part), relocations, and exterior alterations or additions visible from the public right-of-way. "Demolition" is defined broadly enough to include removing a substantial part of features like roofs, siding, windows, doors, and shutters, so a lot of what feels like a renovation is, in the ordinance's eyes, a reviewable change. And "visible from the right-of-way" ignores vegetation, so a tall hedge will not exempt you. Larger projects split between two boards: BAR-S handles projects up to 10,000 square feet, BAR-L handles anything larger.
The paint-color question (the one everyone gets wrong)
Here is the myth: "Charleston makes you pick from an approved color palette." That is false. There is no mandated city color list. Here is the reality: exterior color is within the BAR's scope in the Old and Historic District, but true like-for-like maintenance, repainting the same color, ordinary repair, is exempt as ordinary maintenance, and minor items like painting are typically handled by preservation staff rather than a full board hearing.
The nuance that matters: "reviewed by staff" is not the same as "no review." A same-color repaint as maintenance is generally exempt; a color change on a visible facade is generally a reviewable change routed to preservation staff. Before you assume, confirm the current repaint and color policy with the city for your specific plan.
You can't just tear it down
Inside the Old and Historic District, no structure can be demolished, in whole or in part, without BAR approval, and the board genuinely refuses. It can delay a demolition for up to 180 days, or deny it outright, if it deems the structure of enough architectural or historic interest that losing it would harm the public interest. There is also a demolition-by-neglect rule: an owner cannot lawfully let a covered historic building rot in order to force a teardown. The board has both denied high-profile demolitions and approved some (typically where a home is unsound or chronically flooded), so it is not automatic in either direction. If your plan involves removing a building, treat that as a real, contestable process, not a formality.
The confusion that costs people: local district vs National Register
This is the single most common mistake buyers make, and it runs both ways. A National Register listing is largely honorary. It places no restriction on a private owner using private money, short of projects that receive federal funding, and its main practical benefit is eligibility for historic tax credits. The local Old and Historic District, with the BAR, is what actually restricts your exterior changes. So "it's on the National Register, I can't change anything" is usually wrong, and "it's just an old house, there are no rules" is also wrong if it sits in the local district. The question that matters is not whether the home is historic. It is which district it is in.
The upside: historic tax credits
Historic status is not only restrictions. It can unlock rehabilitation tax credits. There is a federal 20 percent credit for income-producing certified historic structures (not owner-occupied homes), and South Carolina offers its own, including a 25 percent state credit for owner-occupied historic homes where rehabilitation costs exceed $15,000 within a 36-month period. Both require State Historic Preservation Office approval before work begins and compliance with preservation standards. If you are buying a historic home you plan to rehab, this is worth exploring with the SHPO early, because the approval has to come before the work, not after.
Flood plus historic: the Charleston squeeze
Here is the Lowcountry twist that ties this to your flood and insurance due diligence. Raising a home to escape flooding changes its height and massing, exactly what the BAR controls. The city adopted Design Guidelines for Elevating Historic Buildings in 2019. Homes are triaged by category: for lower-category homes, elevating three feet or less may be staff-approved, but anything above that needs the board. Foundation infill has to be recessed lattice, not "beachy" horizontal slats, and garage doors on front elevations are prohibited on elevated homes. In a flood-prone historic district, the elevation question and the BAR question are the same conversation.
Before you buy: the checklist
- Look the address up on the city's interactive zoning map or MAPNET and read for any historic or Landmark overlay.
- If it is in a historic or Landmark district, assume exterior changes may need BAR review.
- Estimate the review level for the change you actually plan: staff review for minor items, BAR-S under 10,000 square feet, BAR-L above.
- Read the city's BAR guidelines for historic properties before you make plans.
- Confirm directly with the city (the BAR office) whether your specific change is staff, BAR-S, or BAR-L. This is the step that settles it.
- Understand the path: Certificate of Appropriateness first, then the building permit. Build the timeline into your plan.
Other historic districts nearby
Charleston is not the only one. Mount Pleasant's Old Village has a Historic District Preservation Commission, Sullivan's Island has a Design Review Board, and Summerville's downtown historic district has its own Board of Architectural Review, each with adopted guidelines. The principle is the same everywhere: in a local historic district, exterior changes need approval before you start.
The bottom line
A historic Charleston home is a privilege and a responsibility, and the rules are not a reason to walk away. They are a reason to know precisely what you are buying. Before you fall for the piazza and the heart-pine floors, I find out exactly what you can and cannot change on that specific address, and what your renovation would actually take. That turns "I'll just fix it up" from a hope into a plan.
Common questions
What is the Charleston Board of Architectural Review (BAR)?
The Board of Architectural Review is the City of Charleston body that reviews the exterior appearance of buildings in the city's historic districts. Created in 1931 as the first of its kind in the country, it reviews new construction, additions, demolitions, and exterior alterations visible from the street, and its approval, a Certificate of Appropriateness, is required before you can obtain a building permit. It does not review interiors.
Can I paint my Charleston historic home any color I want?
Exterior color is within the BAR's scope in the Old and Historic District, but contrary to a common myth there is no mandated city color palette. True like-for-like maintenance, such as repainting the same color, is generally exempt as ordinary maintenance, and minor items like painting are typically handled by preservation staff rather than a full board hearing. Because the policy has nuances, confirm the current repaint and color rules with the city for a specific change.
What is the difference between a local historic district and the National Register?
A National Register listing is largely honorary and places no restriction on a private owner using private money, short of projects that receive federal funding; its main benefit is eligibility for historic rehabilitation tax credits. A local historic district, like Charleston's Old and Historic District, is what actually restricts exterior changes through Board of Architectural Review design review. Buyers often confuse the two, but the local district is the one that governs what you can change.
Can you demolish a historic house in Charleston?
Not freely. Inside the Old and Historic District, no structure can be demolished in whole or in part without Board of Architectural Review approval, and the board can delay a demolition for up to 180 days or deny it outright if the structure is of architectural or historic interest. There is also a demolition-by-neglect rule that prevents owners from letting a covered building deteriorate in order to force a teardown.
Are there historic tax credits for Charleston homes?
Yes. Historic status can unlock rehabilitation tax credits: a federal 20 percent credit for income-producing certified historic structures (not owner-occupied homes), and South Carolina credits including a 25 percent state credit for owner-occupied historic homes where rehabilitation costs exceed $15,000 within a 36-month period. Both require State Historic Preservation Office approval before work begins, so confirm eligibility for a specific property with the SHPO early.
