How these numbers are made
- Property tax: Berkeley County 2026/2027 millage for district 09 (Hanahan): city 79 mills, county 46.5 (operation 41.0, bond 4.5, Cypress Gardens 1.0), Trident Technical College 3.1 and school debt 50.0. Mills are divided by 1,000 and multiplied by the 4% legal-residence assessment ratio.
- School operation millage (146.9) is not charged on an owner-occupied legal residence and is left out; the county sales tax credit (0.001224 for Hanahan) is not modeled, so real bills may be lower.
- Water: Charleston Water System outside-city rates effective Jan 1, 2026 (Hanahan is outside the City of Charleston); the $27.80 minimum bill includes the first 2 Ccf, so the base shown is $27.80 minus 2 Ccf at $4.99 and each Ccf is charged at $4.99. Sewer is billed by Berkeley County at a flat $44.00 a month, which matches the SC Rural Infrastructure Authority 2025 survey; it could not be confirmed against a 2026 Berkeley County Water & Sanitation schedule.
- Electricity: Dominion Energy SC Rate 8, with the $0.36164 daily charge x365/12 plus the $1.00 monthly charge; the energy rate above 800 kWh is a 5-summer/7-winter month weighted average. Some Hanahan addresses may be served by Berkeley Electric Cooperative; franchise fees and gas are not modeled. Typical use of 1,000 kWh is the figure used in the utility's rate-case notice.
- Trash: the city lists Public Works for solid waste and no trash fee appears for Hanahan in the county millage table, so it is treated as no separate fee. Insurance is the 2022 statewide average.
- Water: the 9 Ccf a month is an assumed typical use, not a figure published by Charleston Water System, and assumes the home is a Charleston Water System customer.
- Berkeley County bills a flat Stormwater Utility Fee on the annual tax notice for developed properties in Hanahan (one 2,760 sq ft equivalent residential unit for a single-family home). Its current amount could not be confirmed, so it is not included in the totals.
- Insurance is a statewide 2022 average; premiums near the coast are likely higher.
- Nothing here is legal, tax or insurance advice.
