Short-Term Rental Rules & Investment Potential in Mount Pleasant, SC

Mount Pleasant sits fifteen minutes from downtown Charleston and even closer to Isle of Palms and Sullivan's Island, which makes it an obvious target for investors chasing short-term rental income. Here's what most of them get wrong: they underwrite the deal before checking whether the Town will actually let them operate one.

The Rules, As Written Today

The Town of Mount Pleasant regulates short-term rentals under its zoning code (Sec. 156.007, with nonconforming-use provisions addressed in Sec. 156.142), and the current framework matters enormously to an investment decision:

Short-term rentals are prohibited outright in multi-family dwellings, in the Old Village Historic District, and in any neighborhood where HOA covenants restrict the use — regardless of what the zoning code otherwise allows. Where they are permitted, in qualifying residential dwellings and accessory dwellings, operators must complete an online application, pay a $250 non-refundable review fee, and secure a short-term rental permit before they can even apply for a business license. Permits require a property owner affidavit, proof of liability insurance, proof of taxes paid, and a site plan, and must be renewed annually, with the permit year beginning each July 1st.

The detail that changes the investment math most: the Town caps short-term rental permits town-wide at 1% of total dwelling units, issued first-come, first-served, with operators licensed before January 1, 2020 grandfathered in outside the cap. In practice, that means STR permits are a scarce, capped resource — not something you can assume you'll be granted just because you bought the right house.

What This Means for Your Underwriting

Because permits are capped and legacy operators are grandfathered, a Mount Pleasant property that already carries an active, transferable STR permit is worth a real premium over an identical house without one — you're not just buying real estate, you're buying access to a restricted license. If you're counting on obtaining a new permit after closing, verify current permit availability under the town-wide cap before you finalize your offer, not after. And confirm the specific parcel isn't inside the Old Village Historic District or governed by an HOA that prohibits the use, since neither exception shows up on a standard listing sheet.

A Note on Timing

Municipal short-term rental ordinances change as towns respond to housing pressure and neighborhood pushback, and Mount Pleasant is no exception. The rules summarized above reflect the ordinance in effect at the time of writing.
