Charleston STR Rules: Overlay Zones, Permits, and 7% Tax

Charleston, South Carolina has one of the most geographically-restrictive STR ordinances in the Southeast. The city limits non-owner-occupied STRs (whole-house rentals) to specific overlay districts within the historic peninsula and Cannonborough-Elliotborough. Outside those overlays, only owner-occupied home-share-style STRs are permitted. The 2-night minimum and primary-residence requirement together constrain pure-investor models, pushing the market toward owner-occupant 'house hack' configurations.

Licensing & Registration

Charleston issues three STR permit types. Categorical Short-Term Rental: whole-house rental in the designated overlay only, owner doesn't have to occupy. Bed & Breakfast: traditional B&B with owner present. Short-Term Rental: a room within owner's primary residence, owner present. Annual fee: $250 + life-safety inspection. Cap: 0.4% of total dwelling units in the eligible overlay (a hard ceiling that has bound supply since 2018).

Lodging & Occupancy Taxes

South Carolina state sales tax 6% + accommodations tax 2% = 8% state lodging tax. Charleston adds 2% local accommodations tax + 1% local options sales tax = 3% local. Effective Charleston STR tax: 11%. Some platforms collect; others require operator collection. Charleston County may add a 0.5% transportation tax depending on exact location.

Penalties & Enforcement

Operating without a Charleston STR permit: $1,087 per day per violation (escalates with offense count). The city actively monitors listing platforms and has a dedicated STR enforcement officer. Permit revocation typically follows 3+ confirmed violations within 12 months.

Recent Changes

2025 City Council reaffirmed the overlay-district restriction after pressure to expand it. Investors should not bet on overlay expansion in the medium term. The 0.4% dwelling-unit cap means new STR permits in eligible overlays have effectively zero availability — most operators acquire properties with permits already in place and pay a transferred-permit premium.

Tax Strategy for Compliant Investors

Even where Charleston's rules constrain inventory, properly-licensed STR investors retain the full federal tax stack. Cost segregation accelerates depreciation, and the STR loophole can let losses offset W-2 income for materially-participating owners. See cost segregation for Airbnb properties for the playbook.
