The Charleston County Board of Zoning and Appeals met March 3, 2025, and approved a slate of short‑term rental permits and land‑use variances while deferring one complex tree/ingress variance for further review.
The meeting focused on individual property requests: several short‑term rental (STR) applications in the St. Andrews and James Island areas were approved with standard conditions (limited days per year, parking and noise requirements). The board also approved a set of variances including wetland setback reductions and a request to install a swimming pool closer than the county's 50‑foot critical line. One high‑profile Johns Island application — a proposed subdivision road and associated tree encroachment at 2060 River Road — was deferred after neighbors and several commissioners raised questions about stormwater routing, wetlands and the survival of mature live oaks.
Why it matters: the BZA’s approvals and conditions will determine whether property owners may proceed with renovation, expansion or rental operations, and the deferred Johns Island item highlights ongoing tensions between development, tree protection and stormwater management in low‑lying areas.
Most important actions and conditions - Multiple STR special exceptions were approved. Common conditions included completing the limited site‑plan review, complying with Article 6.8 of the zoning ordinance, limiting aggregate rental days where applicable (72 days for limited home rentals; 144 days for extended home rentals), ensuring required parking and compliance with the county noise ordinance, and providing an on‑site contact/manager. One STR approval (428 Riverland Drive) was made contingent on the owner erecting a privacy fence (minimum 4–5 feet recommended) and meeting staff site‑plan conditions.
- Variances granted included: (a) rear wetland setback reductions to allow reduced deck footprints (Saint Andrews area); (b) a 35‑foot buffer waiver along part of Savannah Highway for Steen Enterprises, conditioned on resolving a chain‑link fence encroachment and providing the required landscape buffer on newly developed portions; and (c) removal of two specified grand live oaks to enable a 58‑lot subdivision (Mungo Homes), subject to mitigation (on‑site canopy tree planting and/or payment into the Charleston County Tree Fund), tree barricades during construction, and certified arborist monitoring.
- A swimming‑pool variance at 1432 Dupree Creek Drive (reducing a 50‑foot critical‑line setback to 36 feet) passed on a divided vote (4–3). Staff conditions require silt fencing during construction, use of stormwater mitigation measures (rain barrels, rain gardens), limiting the encroachment to the footprint shown in the submitted plan, and maintaining the remaining critical‑line buffer under Zoning/Development standards.
- The board deferred a variance request at 2060 River Road (Johns Island) that would have allowed an ingress/egress easement within the critical root zone of a 54‑inch live oak and a proposed 4‑lot subdivision. Commissioners and multiple neighbors pressed the applicant on stormwater routing, Corps of Engineers permitting, alternatives to trenching adjacent to large oak roots, and whether the property owner on which the tree stands had been contacted. The board voted to defer so the applicant can consult neighbors and provide additional information.
Public engagement and staff role Board members heard multiple public commenters on Johns Island who raised concerns about flooding, tree loss and neighborhood character. County staff and the applicant discussed technical constraints: the applicant said stormwater routing to the Stono River is the least‑impact option and that a preexisting force main and easement limit alternative designs. Staff also noted site‑specific permitting conditions that the BZA adopted as part of approvals (site‑plan completion, landscaping/mitigation, tree protection measures, and certified arborist oversight).
What to expect next Applicants whose requests were approved will receive written decisions and staff will list steps needed to obtain permits (zoning/building permits, mitigation plan approval, site‑plan review). The deferred Johns Island case will return after the applicant supplies additional information requested by the board (neighbor outreach, revised stormwater/tree protection analysis).
