Charleston, S.C. – The City of Charleston has completed its first comprehensive architectural survey in 50 years, evaluating thousands of properties on the downtown peninsula for potential historic designation. The effort, which began with securing grant funding from the State Historic Preservation Office, aims to update the city’s understanding of its built environment and inform preservation efforts for the next generation.
The survey assesses buildings that have reached the 50-year threshold for historic consideration, a benchmark established for eligibility. City officials say the initiative is crucial for memorializing Charleston’s architectural evolution and building upon its existing historic legacy. “One of the most wonderful, beautiful things about Charleston is the fact that we are a community where we have a built environment that’s 350 years old,” said Planning and Preservation Director Robert Summerfield. “You can go through different parts of the city and you can see how the city has progressed…like the rings on a tree.”
The undertaking also prioritizes identifying historically significant African American heritage sites, acknowledging that such locations may have been underrepresented in previous documentation. Summerfield emphasized the survey provides an “objective framework” for determining historic significance, assigning each property a category based on its architectural integrity and historical importance.
Historic designation can bring both benefits and constraints for property owners. While stricter review standards may apply to exterior alterations and renovations, designation can also unlock potential tax incentives and preservation credits. The city is also working to clarify the process for property owners who believe their homes may be significant, even if they are not located within existing historic districts.
The survey comes as Charleston continues to grapple with balancing preservation and development. In 1973, a similar effort to define and protect Charleston’s historic character led to the creation of the “French Quarter” district, a single block slated for demolition that was ultimately saved through preservation activism, according to historical accounts. That project, spearheaded by Alan Leigh Baier and supported by Mayor J. Palmer Gaillard, represented a $6 million investment in the city’s tourism economy. The current survey builds on that legacy, aiming to address gaps in the city’s historic inventory.
Summerfield acknowledged that the surveying process can be confusing, particularly for newer residents. To address this, the city is hosting a session through its Board of Architectural Review (BAR) University program at the Galliard Center on Tuesday, February 24, 2026. A contractor involved in the survey will explain the evaluation process, classification meanings, and how property owners can navigate the designation process.
The survey findings will be presented to the Board of Architectural Review in March and then to Charleston City Council for potential adoption in the fall. City leaders are also seeking funding for a similar survey in West Ashley. Summerfield stressed that the BAR’s role extends beyond aesthetic considerations, serving as a resource for the entire community on preservation matters. “BAR is about more than just whether a certain color of paint is historically appropriate,” he said. “They really are here as a resource for the community to have that preservation conversation.”
