Do you need a building permit in Chester County, South Carolina?

Yes. Residential construction in county-administered Chester County requires a building permit.7 Before issuance, the county requires a 911 address, recorded plat, tax map number, plans, contractor information and applicable water, sewer or septic documentation.14 A property in a floodplain also needs an elevation survey and elevation certificate prepared by a licensed surveyor or engineer.15

South Carolina's 2021 code cycle took effect in 2023; the state also lists 2024 codes, so confirm the edition enforced for the project date with Building + Zoning.1612 Chester County inspections run from foundation and rough-in stages through final inspection; final wastewater approval and duct-blast documentation must reach the office before the final inspection can be completed.17 A residential structure cannot be occupied until it passes final inspection and receives a Certificate of Occupancy.18

Who issues Chester County building permits, and how do you reach the office?

Chester County Building + Zoning reviews plans, coordinates inspections and issues building permits at 1476 J.A. Cochran Bypass in Chester; call (803) 581-0942.12 The department lists unincorporated Chester County, Great Falls and Fort Lawn in its service area, but excludes Chester city, Richburg and Lowrys.19 Inside Chester city, the city building official handles building permits; DES still handles septic approval where public or community sewer is unavailable.46

Chester County provides online building permitting and plan review, and inspections can be scheduled online or by calling the office.2017 County Council sets zoning-permit and zoning-compliance fees; the published building fee schedule is dated 2017, so ask Building + Zoning for the current project total.2122

Does Chester County have zoning?

Chester County zoning applies throughout unincorporated Chester County, with allowed uses, lot sizes, setbacks and height limits determined by district.823 In the AG Agricultural District, residential lots need at least 4 acres; front yards measure 25 feet from the road right-of-way, side yards 15 feet from the interior side lot line and rear yards 20 feet from the interior rear lot line.1324 AG structures generally have a 35-foot roof-line height limit, with listed exceptions.25

Chester city and Great Falls have their own zoning regulations; county district standards below concern unincorporated land.592 DES retains septic approval in Chester city; Great Falls also requires a written private-sewage-disposal permit from the town superintendent and state approval for septic tanks.626

AG manufactured homes on single residential lots require a permanent foundation, masonry or concrete underpinning, removal of wheels and mobile features, tie-downs, specified roofing and parking; RS-1 prohibits manufactured homes.27 Cottage-lot homes in Urban Conservation Subdivisions have a 500-square-foot minimum, which does not establish a countywide dwelling minimum.28

How do septic permits work in Chester County?

South Carolina DES issues septic permits for Chester County homes and manufactured homes without public or community sewer; the county cannot issue the building permit until the required septic permit is obtained.3 Apply online with a plat or deed; the traditional process includes a site-suitability evaluation, and the application fee is $150.29 A Permit to Construct must precede installation and lasts 5 years; renewal or changes require a new application and fee.30

The installer must schedule a DES inspection before covering the system; if the inspector does not arrive within 30 minutes, a licensed installer may self-inspect and submit the required final-inspection form.31 Only 36.1% of Chester County soils are rated without severe limitations for a conventional septic drain field, so make site approval a purchase contingency.32 For application questions, call 1-855-731-2504 or email OSWWCentral@des.sc.gov.33

Can you live in an RV or tiny home on land in Chester County?

In unincorporated Chester County’s R-3 and R-4 districts, commercial campgrounds accommodating RVs, campers, travel trailers and tents require a Board of Zoning Appeals special exception, at least 10 acres, a 500-foot setback from residential property lines and no more than 10 vehicles or campers per acre.3435 Campground approval also requires a site plan, road standards and compatibility with the district.3637 The ordinance’s camper definition excludes permanent residential use; commercial-campground approval does not establish permission to live in an RV on a private residential lot.34 We could not confirm private-lot RV occupancy or camping during construction; ask Building + Zoning about the parcel before connecting utilities.12

We could not confirm a separate tiny-home occupancy rule; ask Building + Zoning about the proposed dwelling and district.12 Residential construction requires a building permit, and occupancy requires a passed final inspection and Certificate of Occupancy.118

What are the steps to build a home in Chester County?

  1. Confirm that Chester County, rather than a municipality, has jurisdiction and ask Building + Zoning to identify the parcel’s district, allowed use, lot-size rule, setbacks and height limit.1923
  2. Obtain the 911 address, recorded plat and tax map number, then prepare the plans and contractor documentation; owner-builders must personally supervise, build for owner/family use and complete a notarized, recorded disclosure.3811
  3. Document the water and wastewater path; a site without public or community sewer needs state septic approval.393
  4. Submit the residential permit package and any floodplain elevation documents that apply.2015
  5. Schedule the required construction inspections and secure final wastewater approval.40
  6. Do not occupy the home until the final inspection passes and Chester County issues the Certificate of Occupancy.41

What should you check before buying land in Chester County?

Start with jurisdiction and zoning: confirm whether the parcel is in unincorporated Chester County or a municipality, then verify the district, allowed dwelling type, lot size, setbacks, height limit and subdivision status with Building + Zoning.4243 The county reviews plats for compliance with its development regulations in county-administered areas.44 A commercial or industrial project needs a Department of Transportation encroachment permit, but we could not confirm the approval rule for a residential driveway; ask Building + Zoning before assuming existing access is sufficient.4512

Treat wastewater, water and flood risk separately. Only 36.1% of county soils are rated without severe limitations for a conventional drain field.32 Before drilling an individual residential well, South Carolina requires a Notice of Intent and a $70 fee; the well driller must also give DES 48 hours' notice before installation.46 Floodplain construction requires elevation documentation, and the county office checks floodplain status.15

Watch-outs

  • Chester County lists Great Falls in its service area, but Great Falls has its own zoning ordinance and an additional town private-sewage-disposal permit; confirm the applicable approvals with Building + Zoning and the town superintendent.19926
  • Private-land RV living, temporary camping, tiny-home occupancy and a countywide minimum dwelling size remain unconfirmed; ask Building + Zoning about the specific parcel and proposed use.12
  • Only 36.1% of Chester County soils are rated without severe limitations for a conventional septic drain field, so obtain state site approval before treating a parcel as buildable.32
  • Chester County owner-builders must build for their own or family use, supervise construction and record the required notice; sale or rent within 2 years creates a presumption against the exemption.11
