Short-term rental rules in Charleston
Rules depend on the exact city, county and zoning district, and they change. Here’s what the official sources say as of November 2026:
- City of Charleston residential short-term rental permits generally require the property to be the owner’s primary residence (verified through the county 4% legal-residence assessment), with the owner residing there and present overnight while guests stay. Investment properties are generally not eligible except commercial STRs in the City’s designated STR overlay zone. Source: City of Charleston: STR FAQs
- Accommodations taxes apply to short-term residential rentals. Source: City of Charleston: Accommodations Tax for STRs
- Nearby beach towns (Folly Beach, Isle of Palms, Sullivan’s Island, Kiawah) and Charleston County each set their own rules: confirm current rules with that jurisdiction.
Summaries, not legal advice. Confirm current rules with the locality, and any HOA or condo association, before you make an offer.
HOA, condo and insurance considerations
Lowcountry properties: flood and wind coverage can be significant costs; get quotes during due diligence.
Many vacation communities have HOA or condo rules that are stricter than the city or county: minimum stays, rental registration, guest limits or outright bans. Ask for the governing documents and rental rules before your due-diligence period ends. Lenders review condo projects too, so share the association’s details early.
How the financing usually works
- Mostly your family’s place, occasional renting: usually a second home. Under Fannie Mae’s occupancy rules it must be a one-unit home under your exclusive control, not primarily operated as a rental, and rental income generally can’t be used to qualify.
- Mostly renters: lenders treat it as an investment property, which is underwritten and priced differently, and documented rental income can sometimes help you qualify.
- Resort or condo rental programs that control your calendar can affect second-home eligibility. Share any management agreement with me early.
- Count the cost of two homes: your current payment plus the new home’s taxes, insurance, HOA dues and any rental-license or inspection costs.

Before you write an offer
- Confirm the jurisdiction (city vs. unincorporated county) and zoning district for the exact parcel.
- Check whether a short-term rental permit, license or registration is available for that address, and any cap or waitlist.
- Get the HOA or condo rental rules in writing.
- Price insurance (including flood or wind where relevant) during due diligence.
- Decide honestly how you’ll use it, so the loan is classified correctly from day one.

Charleston questions
Can I buy an investment property in Charleston, SC and run it as an Airbnb?
Generally not in the City of Charleston’s residential areas. Residential short-term rental permits generally require the property to be the owner’s primary residence, with the owner present overnight while guests stay; investment properties are generally limited to commercial STRs in the City’s designated overlay zone.
Can I finance a Charleston vacation home as a second home and still rent it out sometimes?
Possibly. Under Fannie Mae’s guidelines a second home must be a one-unit home you occupy for part of the year, keep under your exclusive control and don’t primarily operate as a rental, and rental income generally can’t be used to qualify. If renting in Charleston is the main plan, expect investment-property financing instead, and make sure local short-term rental rules allow your plan first.
