Charleston's Short-Term Rentals: The Rules That Matter

Every city handles short-term rentals a little differently. In Charleston, South Carolina, there are 11 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Occupancy Limits

Charleston Ord. 2018-141 caps short-term-rental occupancy at two adults per bedroom plus two additional persons, with a hard ceiling tied to the certificate of occupancy regardless of dwelling size or layout.

Key details: Formula: 2 per bedroom + 2. Children: Under 12 exempt. Ordinance: Ord. 2018-141. Enforced by: Livability & Tourism.

First overage warning then fine up to $1,087 per occurrence in municipal court; repeated overages within twelve months can revoke the STR permit citywide.

Compared to other cities, Charleston takes a harder line on occupancy limits. The enforcement and penalty structure reflects that.

Insurance Requirements

Charleston requires every short-term-rental operator to carry liability insurance covering commercial transient use, with proof attached to the annual permit application reviewed by Livability and Tourism staff before issuance.

Key details: Min coverage: Equivalent of $1M. Proof: Certificate of insurance. Renewal: Annually. Lapses: Auto-suspension.

Operating without valid coverage triggers permit suspension, fines up to $500 per booking night, and disqualification from re-application for twelve months.

Host Presence Rule

Category 1 short-term rentals in Charleston's residential zones require the owner to use the property as a primary residence and remain physically present during guest stays, with strict documentation reviewed annually.

Key details: Category: Cat 1 (residential). Presence: Onsite during stays. Primary residence: Required. Transferable: No.

Investigators issue citations up to $1,087 per night for absent-host operation, plus permit revocation and one-year ban on re-application at the address.

Compared to other cities, Charleston takes a harder line on host presence rule. The enforcement and penalty structure reflects that.

Host Platform Liability

Charleston requires every short-term-rental listing on Airbnb, Vrbo, and similar platforms to display the city-issued permit number prominently, shifting partial enforcement responsibility onto hosting platforms operating within municipal limits.

Key details: Display: Permit # in listing. Platforms: Airbnb, Vrbo, Booking. Enforcement: Web scraping. Fine: $500/day.

Listings without permit numbers receive cease-advertising notices, $500 daily civil fines per listing day, and possible referral to SC Department of Revenue for unremitted accommodations tax.

Rentals of thirty consecutive days or longer fall outside Charleston's short-term-rental program and instead follow standard South Carolina landlord-tenant law, freeing owners from STR caps while still owing applicable city taxes.

Key details: Threshold: 30+ consecutive days. Governing law: SC URLTA Title 27. Lease: Written required. STR tax: Not owed.

Mislabeling short stays as long-term to evade STR rules triggers retroactive accommodations tax, $1,087 per-night fines, and possible criminal misdemeanor charges for tax evasion.

The rules around extended home share in Charleston lean permissive, but that does not mean anything goes.

Primary-Residence-Only Rule

Charleston restricts residential-zone short-term rentals to owner-occupied primary residences claiming the four-percent legal residence assessment ratio, blocking investor-owned vacation homes from operating outside designated commercial categories.

Key details: Test: 4% assessment ratio. Investor LLCs: Disqualified. Zones: Residential / Old Historic. Origin: Ord. 2018-141.

Operating a non-primary residence as a Cat 1 STR results in permit denial or revocation, civil fines up to $1,087 per night, and referral to the SC Department of Revenue.

Compared to other cities, Charleston takes a harder line on primary-residence-only rule. The enforcement and penalty structure reflects that.

Repeat Violator Strikes

Charleston Livability and Tourism staff revoke short-term-rental permits after three sustained violations within twelve months, with a one-year cooling-off period before the same property may reapply for any STR category.

Key details: Strikes: 3 in 12 months. Cooling-off: 1 year. Appeal venue: Board of Zoning Appeals. Public registry: Yes.

Three sustained citations within twelve months trigger automatic revocation, one-year reapplication ban, and listing on the city's public non-compliant property registry.

This is not one of those rules that cities tend to ignore. Charleston actively enforces its repeat violator strikes requirements.

Permit Requirements

Charleston requires a Short-Term Rental Permit under the Accommodations Ordinance (Chapter 29, Article X). All STR operators must register, obtain a business license, and meet zoning and safety requirements.

Key details: Permit: Required with business license. Code Section: Chapter 29, Art. X. Local Contact: Available 24/7 within 30 min. Fine: Up to $1,092.50/day without permit.

Operating without a permit results in fines up to $1,092.50 per day. The city actively enforces through complaint-based and proactive monitoring.

Compared to other cities, Charleston takes a harder line on permit requirements. The enforcement and penalty structure reflects that.

Taxes & Fees

Charleston STR operators must collect and remit a 2% Local Accommodations Tax and the state's 7% Accommodations Tax. A city business license fee also applies based on gross rental income.

Key details: Local Tax: 2% Accommodations Tax. State Tax: 7% SC Accommodations Tax. Business License: Required, fee based on income. Reporting: Quarterly.

Failure to collect and remit taxes results in penalties, interest, and potential loss of the STR permit and business license.

This is one of the stricter rules in Charleston's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Parking Rules

Charleston requires STR operators to provide adequate parking for guests. Operators must include parking information in the listing and guest materials. On-street parking rules apply in many areas.

Key details: Requirement: Must inform guests of parking options. Historic Areas: Metered/time-limited street parking. Off-Street: Recommended where possible. Enforcement: City parking management.

Guests who violate parking rules receive standard parking citations. Persistent parking issues from STR guests may factor into permit renewal decisions.

Noise Rules

Short-term rental guests in Charleston must comply with the city's noise ordinance. STR operators are responsible for ensuring guests do not create excessive noise, especially during nighttime hours.

Key details: Quiet Hours: 10 PM–7 AM. Operator Duty: Must provide noise rules to guests. Response Time: Local contact within 30 minutes. Penalty: Permit revocation for repeated violations.

Noise violations by STR guests can result in fines to the operator and potential permit revocation after repeated complaints.

This is not one of those rules that cities tend to ignore. Charleston actively enforces its noise rules requirements.
