Short-Term Rental Rules in Charleston, SC: An Owner’s Guide

Charleston is an incredible place to own a vacation rental — but not every property can legally operate as one.

The City of Charleston has specific short-term rental rules based on where a property is located, how it is used, and, in some cases, its age or historic status. Understanding those requirements is an important first step whether you already own a home in Charleston or are considering adding one to your investment portfolio.

At Curated Vacation Properties, we work with Charleston property owners to understand the full potential of their homes, from rental performance and guest experience to the realities of operating in one of the Lowcountry’s most sought-after destinations.

What Qualifies as a Short-Term Rental in Charleston?

The City of Charleston defines a short-term rental as a dwelling unit or bedroom rented for fewer than 30 consecutive days. (City of Charleston)

To legally operate, owners need the appropriate city permit and business license, and the STR permit number must appear in rental advertising. (City of Charleston)

For residential short-term rentals, the property generally must be the owner’s full-time primary residence and qualify for the 4% owner-occupied property tax classification. (City of Charleston)

Commercially zoned properties within Charleston’s designated Short-Term Rental Overlay may follow different requirements. (City of Charleston)

It’s also important to verify that the property is actually within the City of Charleston. A Charleston mailing address can fall under another municipality or Charleston County, where different short-term rental regulations may apply.

Charleston’s Three Residential STR Categories

Residential short-term rentals within the City of Charleston fall into three categories based primarily on location. (City of Charleston)

Category 1: Old and Historic District

Category 1 covers Charleston’s Old and Historic District.

In addition to the primary-residence requirement, the short-term rental must be located within an existing structure or accessory building individually listed on the National Register of Historic Places.

Only one STR unit is permitted per property, and applicable off-street parking requirements must be met. (City of Charleston – Category 1)

Category 2: Other Areas of the Peninsula

Category 2 applies to areas of the Charleston peninsula outside the Old and Historic District and Short-Term Rental Overlay.

The building containing the STR generally must be at least 50 years old. Properties are also limited to one STR unit and must meet applicable parking requirements. (City of Charleston – Category 2)

Category 3: Off-Peninsula Charleston

Category 3 covers incorporated areas of Charleston outside the peninsula.

These properties do not have the National Register requirement of Category 1 or the 50-year building requirement of Category 2. However, primary-residence, parking, licensing, safety, and other operating requirements still apply. (City of Charleston – Category 3)

Charleston STR Permit Requirements

Getting approved to operate a short-term rental involves more than submitting an application. Depending on the property, the city’s process can include:

• Zoning and application review

• Fire Marshal review

• Safety inspection

• City business licensing

• Applicable parking requirements

The city also states that an STR cannot be advertised or operated until required approvals and inspections are complete, fees are paid, a valid Certificate of Operation has been issued, and the corresponding business license has been obtained. (City of Charleston)

STR permits must also be renewed annually by their original date of issuance. (City of Charleston)

The city currently lists a $345 zoning and application review fee, with additional fire inspection, plan review, and business licensing costs. Because fees and requirements can change, owners should always verify current information directly with the city before applying. (City of Charleston – Applicable Fees)

Taxes for Charleston Short-Term Rentals

Short-term rental income may be subject to South Carolina and local sales and accommodations taxes.

Even when a booking platform or property manager assists with collecting or remitting certain taxes, owners should understand which tax obligations apply to their specific property and rental arrangement. The city states that property owners are ultimately responsible for ensuring applicable accommodations taxes are collected and submitted to the proper state and local agencies. (City of Charleston)

Before Buying a Charleston Property for Short-Term Rental Use

If rental income is part of the reason you’re purchasing a Charleston property, confirm its eligibility before building your investment projections around short-term rental revenue.

A few questions should come first:

• Is the property within the City of Charleston?

• Which STR category applies?

• Does it meet the primary-residence requirement?

• Are there historic or building-age restrictions?

• Does the property meet parking requirements?

• Is there an existing STR permit or enforcement history?

• Does the intended rental setup meet zoning and safety requirements?

Once those questions are answered, you can make a much more informed assessment of the property’s actual rental potential.

Is Charleston a Good Market for a Short-Term Rental Investment?

Charleston’s enduring appeal gives vacation rental owners plenty to be excited about, from its historic character and acclaimed dining to beaches, events, and year-round tourism. But here, finding the right property means looking beyond location alone.

The city’s residential STR rules limit which homes can qualify, with requirements tied to primary-residence status, location, parking, and, in some areas, the property’s age or historic designation. (City of Charleston)

For owners and buyers, Charleston can offer meaningful vacation rental potential when the property and rental strategy align with those rules. Establishing eligibility first creates a much clearer foundation for evaluating demand, projected revenue, operating costs, and the property’s long-term potential.
