Zoning, building permits and septic rules in Bennettsville, South Carolina

Bennettsville, South Carolina has its own zoning ordinance, and the city requires a building permit before a structure is erected or added to12. The city's planning and zoning department handles both. Septic permits, where a lot is not on public sewer, come from the state's environmental agency, not the city or Marlboro County3.

Does Bennettsville have zoning, and what does it mean for lots and setbacks?

Yes. Bennettsville adopted its own zoning chapter in Chapter 152 of the city code, and land inside city limits is divided into districts shown on the Official Zoning Map14. The districts include A-1 through A-4 residential, commercial and ROI districts, a mobile home park district, and a historic district4.

In the A-1 single-family residential district, a single-family dwelling needs at least 12,000 square feet9. Front yards must be at least 35 feet deep and rear yards at least 25 feet10. The maximum height of permitted uses in A-1 is 35 feet11. Other districts differ, so confirm the district of a specific parcel before you buy.

Can you put a mobile home, tiny home or RV on a lot in Bennettsville?

Mobile homes are excluded from single-family use in the A-1 district, and the city provides for them through a planned-development mobile home park district6. Accessory apartments are allowed in the A-2 district under section 152.089(b) of the city code12.

We could not confirm Bennettsville's rules for living in an RV or for tiny homes, so ask the Planning & Zoning Department at the city before moving anything onto a lot13.

Do you need a building permit in Bennettsville, and who issues it?

Yes. Inside Bennettsville, no building or structure, and no addition to one, may be erected unless the building inspector has issued a permit and the required fee is paid2. Ordinary minor repairs and maintenance, such as painting or reroofing less than 100 square feet, may be done without a permit2.

The City of Bennettsville's Planning & Zoning Department reviews construction plans and permits and inspects development inside city limits13. Marlboro County's Building Codes Department does not cover the city; its jurisdiction is unincorporated Marlboro County and the towns of Blenheim, Tatum and Clio14. The city adopted the international building codes, as amended by the state codes council15.

Can an owner build their own home in Bennettsville?

South Carolina lets an owner act as their own unlicensed builder for a one- or two-family home that the owner or family will occupy, and that exemption requires the owner to personally appear and sign the building permit application8. Sale or rent within two years of completion is presumed to mean the home was built for sale or rent8.

Bennettsville's own code lets a homeowner install or maintain buildings, wiring or plumbing on their own property if the work is done by the owner and used by the owner's family, but the exemption does not excuse the owner from getting a permit7.

How do septic permits work inside Bennettsville?

Septic permits in South Carolina come from the state, not the city. Anyone building a home on property not served by a public or community sewer must first get SCDES approval and a permit to install a septic system, and without it the building permit cannot be issued5. The application fee is $150 and a Permit to Construct is good for five years16.

The state also states that an onsite wastewater permit cannot be issued where public sewer is accessible17. For a lot inside the city, the first question is therefore whether city sewer reaches it. We could not confirm the city's sewer-connection rules, so ask the city and SCDES18.

Building a home in Bennettsville: the steps, in order

  1. Confirm the parcel's zoning district on the Official Zoning Map with the Planning & Zoning Department413.
  2. Check lot size and setbacks for that district, for example 12,000 square feet and a 35-foot front yard in A-1910.
  3. If no public sewer serves the lot, get SCDES site approval and a septic permit first5.
  4. Apply for the city building permit, which the building inspector issues once the fee is paid2.
  5. Build to the South Carolina building codes the city enforces15.
  6. Expect water, gas and electric service to be started only after a building permit or certificate of occupancy has been issued19.

What stays with Marlboro County, and what should you check before you buy?

The county's building permit rules cover unincorporated Marlboro County, not the city; for land outside city limits see the Marlboro County page14. Septic permits and private wells follow state rules everywhere in the county320.

Before you buy, check flood hazard boundaries, which are adopted into the city's zoning chapter21. Marlboro County's effective property tax rate is 0.6%22, and about 19% of its soils are rated not limited for a conventional septic drain field23, so lots outside sewer service often need a site evaluation or an engineered system.

Watch-outs

  • Searches for Bennettsville building permits often land on Marlboro County's permit page, but the county's Building Codes Department does not issue permits inside the city14.
  • Inspection stages, RV use, tiny homes, minimum dwelling size and short-term rentals inside Bennettsville were not confirmed; ask the city Planning & Zoning Department13.
  • Septic permits and any sewer-connection requirement for lots inside the city were not confirmed; ask SCDES and the city before relying on a septic system17.
  • South Carolina adopted the 2024 building codes with a local implementation date of January 1, 2027, so the edition enforced may change24.
