Executive Overview

Short-term rentals are allowed in Wadmalaw Island, SC, but they are subject to Charleston County regulations since Wadmalaw Island is an unincorporated area within Charleston County. The regulations differ significantly from the more restrictive City of Charleston rules and offer more flexibility for investors, though with important day-use limitations and permitting requirements.

Starting a Short-Term Rental Business in Wadmalaw Island/Charleston County

1. Understand Your Property's Classification

In Charleston County unincorporated areas (which includes Wadmalaw Island), short-term rentals fall into three primary categories:

• Limited Home Rental: Short-term rental of a primary residence (maximum 72 days per calendar year)
• Extended Home Rental: Short-term rental of an investment property (maximum 144 days per calendar year) - requires special exception from County Zoning
• Commercial Guest House: Short-term rental in commercially zoned districts

2. Determine Zoning Eligibility

Before proceeding, verify your property's zoning classification with Charleston County Planning and Zoning. Properties must meet specific criteria for their intended use category.

3. Secure Required Permits and Licenses

All short-term rental operations in Charleston County require proper permitting. For Limited Home Rentals, the process is more streamlined as it applies to primary residences. Extended Home Rentals require special exception approval from County Zoning, which involves a public hearing process.
