Short-Term Rentals on Lake Hartwell, South Carolina

The Clemson Football Premium

Clemson home football games generate some of the most concentrated short-term rental demand of any lakefront market in the Southeast. The Tigers play in Memorial Stadium with 80,000-seat capacity, and the game-day boating culture unique to Lake Hartwell creates demand for lakefront rentals within boating distance of campus from August through November. A well-positioned lakefront home near the Clemson end of the lake can command $500 to $1,500 or more per night on game-day weekends, compared to $200 to $400 per night during comparable non-game weekends in summer.

Clemson plays seven or eight home games per season. Not all of them generate equivalent rental demand; SEC and ACC rivalry games, night games, and early-season openers tend to pull more demand than mid-week or low-profile games. Owners who time their rental calendar around game-day maximums can capture six to eight premium-rate weekends per fall, then fill the calendar with summer recreational renters in June, July, and August. That combination creates one of the more interesting income profiles of any SC lake property.

Properties near the Anderson-side Portman Marina area do not benefit as directly from the Clemson game-day premium — the marina and most of the Anderson County shoreline is a 20-to-30-minute boat ride from Clemson, which is too far for most game-day boating groups. Summer recreational demand still exists throughout the Anderson County shoreline, but the football season revenue spike is much stronger for the Oconee County and Pickens County shoreline near Clemson.

HOA and POA Restrictions on STR

Before planning a short-term rental income strategy, verify whether the property is subject to an HOA or POA with rental restrictions. Many Lake Hartwell SC communities have deed restrictions that limit or prohibit short-term rentals entirely. Common restrictions include minimum rental terms (30 days or longer, effectively prohibiting Airbnb or Vrbo-style weekend rentals), limits on the number of rental periods per year, and requirements for owner-approved tenant lists that preclude rental platform guests.

These restrictions are typically found in the Declaration of Covenants, Conditions, and Restrictions (CC&Rs) for the community and are legally binding. Violations can result in fines, legal action by the HOA, and in some cases a lis pendens on the property title. Always review the full CC&Rs before purchasing a property you plan to use as an STR, and do not rely on the agent's characterization of what is permitted — read the document itself or have an attorney review it.

How to Actually Check Before You Buy

The sequence matters. Before you ask your agent whether STR is allowed, request the governing documents yourself. In South Carolina, these are public records if the community is a recorded HOA or POA. Ask the listing agent for the full Declaration of Covenants, Conditions, and Restrictions (CC&Rs), the bylaws, and any amendments. The CC&Rs are the binding document; the bylaws govern HOA operations. Read the rental restriction language yourself rather than asking someone to summarize it — summaries are where errors happen.

Specifically look for: minimum rental duration clauses (language like "no lease for less than 30 days" kills the Vrbo model entirely); owner-occupancy requirements during rental periods; limits on the number of rentals per year; and any language about guest registration or association approval. Some HOAs distinguish between "guests" and "renters" in ways that create interpretive ambiguity; if the language is unclear, have a South Carolina real estate attorney review it before you close, not after you receive a cease-and-desist letter.

If the property has no HOA, verify with Anderson County or Oconee County zoning that the parcel's zoning classification permits short-term rental use. Unincorporated county areas in SC are subject to county zoning codes, and some residential zoning categories have been updated to require STR registration or limit occupancy. A 15-minute call to the county planning and zoning office before closing is worth infinitely more than a compliance dispute after.

County and Municipal STR Regulations

South Carolina allows counties and municipalities to regulate short-term rentals, and the regulatory environment varies across the three Hartwell SC counties. Anderson County's approach to STR regulation in unincorporated areas and the specific requirements for registration, inspection, and occupancy limits are managed through the county planning and zoning office. Properties within Anderson city limits face city-specific rules.

South Carolina imposes state and local sales and accommodations taxes on short-term rental income. The SC state sales tax rate is 5 percent, and counties and municipalities may impose additional local accommodations taxes of 1.5 to 3 percent. STR operators are required to collect and remit these taxes and to maintain records. Rental platforms like Airbnb and Vrbo typically collect and remit state-level accommodations taxes automatically on behalf of hosts in South Carolina, but local tax obligations may require additional registration and remittance by the property owner. Verify current requirements with the SC Department of Revenue and the applicable county revenue office before beginning rental operations.

Income Analysis: Does It Pencil Out?

A lakefront home near Clemson with direct water access, a usable dock, sleeping capacity for 8 to 12 guests, and strong listing photos on Vrbo or Airbnb might reasonably generate the following gross rental income: 8 Clemson game-day weekends at $1,000 average = $8,000. Ten summer weekend bookings (Memorial Day through Labor Day) at $600 average = $6,000. Ten weekday or midweek summer bookings at $300 average = $3,000. Total gross: approximately $17,000 per year in a reasonably well-managed scenario without a property manager.

A property manager typically charges 20 to 30 percent of gross revenue for full-service management including booking, cleaning coordination, and guest communication. At 25 percent, the management cost on $17,000 gross is $4,250, leaving net rental revenue of $12,750. The carrying cost of a $600,000 lakefront property in Anderson County (taxes, insurance, Corps permit, maintenance) runs roughly $8,000 to $12,000 per year for a primary resident or $14,000 to $18,000 for a non-primary STR owner — the 6 percent assessment ratio dramatically increases the tax load for non-primary use. At non-primary tax rates, the rental income may cover less than half of the annual carrying costs.

The economics improve significantly for owners who use the property as their primary residence and rent it only during their personal absences (summer trips and away-game periods), maintaining the 4 percent tax classification while generating supplemental rental income. This “rent-while-away” approach maximizes the tax efficiency of primary residence ownership while capturing the high-demand windows without full STR operating overhead.

Insurance Implications of Short-Term Rental Use

Using a lakefront home as a short-term rental typically voids the standard homeowner's insurance policy's liability coverage for guest injuries. Standard residential policies are written for owner-occupied or occasional guest use; they specifically exclude commercial rental activity. If you plan to rent your property, notify your insurance carrier and obtain a landlord or vacation rental endorsement, or replace the standard homeowner's policy with a vacation rental policy that covers guest liability. Rental platforms like Airbnb offer host protection programs, but these are supplements to proper insurance, not substitutes.

Dock liability during rental periods is a specific concern. Guests unfamiliar with the dock and the lake's drawdown conditions, who may arrive after dark or who may have been drinking, represent a higher liability exposure than the property owner's own family using the dock. Verify explicitly with your insurer that rental guests are covered under your policy for dock-related incidents.
