HPC approves 312‑sq‑ft accessory dwelling in Hamlin Beach historic district, 9‑0

The Charleston County Historic Preservation Commission voted unanimously to grant a certificate of historic appropriateness for construction of a 312‑square‑foot accessory dwelling unit behind a house on Jefferson Road within the Hamlin Beach Community Historic District.

Staff presenter Emily Pickett said the proposed single‑story structure would be framed with two‑by‑four studs, insulated with spray foam, finished with shiplap interior walls, vinyl windows, a flat shingle roof and vinyl siding, and that the applicant described the building materials as consistent with the primary residence. Pickett said the accessory structure "will likely not be visible from the Jefferson Road right of way" and that the closest identified contributing resources are more than 1,500 feet away.

Pickett recommended approval with the condition that any major changes be processed pursuant to the county historic preservation ordinance. No public input was recorded as having been received prior to the meeting; at the public comment period Myra Richardson raised a question about whether access across a small triangle parcel in the rear had been addressed.

A commission member moved to approve, citing the approval criteria in county ordinance (21‑5): compatibility of architectural features, limited visual impact because the structure is not visible from the road, and that other criteria did not apply. The commission voted by roll call: Chair English Hertel and eight other commissioners voted in favor; the motion passed 9–0.

Staff noted that the HPC’s decision is final for certificates of historic appropriateness and that any person with a substantial interest may appeal to the Charleston County Circuit Court within 30 calendar days.
