Do you need a building permit in Hardeeville, SC?

Hardeeville requires a building permit for structural work, including adding, relocating or removing interior load-bearing walls or windows.12 Hardeeville also lists storage buildings, garages, carports and decks over 200 square feet, and any structure attached to a dwelling, as work requiring a building permit.12 A qualified detached accessory structure under 200 square feet appears on the city’s no-building-permit list, but still needs planning/zoning approval.12 Ask Building Safety how the city classifies the exact proposed structure before buying a shed or starting construction.1

Who is the Hardeeville building department, and where do you apply?

Hardeeville’s Building Safety Department lists its office at 3345 Argent Blvd, Unit 102 Ridgeland SC 29936, with phone 843-784-2231 and email [email protected].1 Hardeeville requires building-permit applications through the building portal; the city’s Permit & License Portal also supports viewing existing building permits, requesting inspections and uploading supporting documents.16 Hardeeville building-related fees depend on project type and total project valuation, so request a project-specific fee estimate from a permit technician.1 City zoning questions and plat approval go to Hardeeville Planning rather than the building-permit counter.13

Does Hardeeville have zoning, lot-size rules and setbacks?

Every parcel inside Hardeeville city limits has a zoning district designation and must meet the Municipal Zoning and Development Ordinance standards.2 Hardeeville’s SFR1 district requires at least 20,000 square feet of lot area and an 80-foot minimum lot width.14 The SFR2 district requires at least 10,000 square feet and a 70-foot minimum width, with front, side and rear setbacks of 25, 10 and 15 feet respectively.815 Hardeeville’s RA rural/agricultural district requires at least 5 acres and a 400-foot lot width.7 Ask Hardeeville Planning to confirm the parcel’s designation and applicable development standards before selecting a house footprint or dividing land.13

How do septic permits work inside Hardeeville?

A home or manufactured home in Hardeeville without public or community sewer needs SCDES approval and a septic installation permit before installation; the application fee is $150.16 Available BJWSA water and sewer service can trigger mandatory connection provisions, so establish service availability before planning a private wastewater system.5 For septic application questions before submission, call the DES Onsite Wastewater Program at 1-855-731-2504 or email [email protected].17 The installer must contact SCDES before covering the system, and a compliant installation receives an approval-to-operate permit.18 Off-grid sanitation does not remove the requirement for septic site approval and a permit.19

Can you live in an RV or tiny home in Hardeeville?

We could not confirm permission for residential RV occupancy on private land in Hardeeville; ask Hardeeville Planning about the parcel and proposed duration of occupancy.13 Hardeeville’s public-property camping prohibition covers city-owned parks and other public areas, with exceptions, and does not establish permission to camp on private land.20 We could not confirm a city-specific tiny-home occupancy rule or minimum dwelling floor area; ask Planning before treating a small structure as a residence.13 Hardeeville’s MU district permits an accessory dwelling up to 800 square feet subject to other ordinance standards, but that district-specific provision does not establish a citywide tiny-home entitlement.9

Building a home in Hardeeville: what are the steps?

Start with Hardeeville Planning: confirm city limits, zoning designation, lot dimensions and the proposed residential use.132 Next establish BJWSA service availability; if public or community sewer is unavailable, obtain SCDES septic approval and the installation permit.54 Submit the building-permit application and supporting documents through Hardeeville’s portal, and use the portal to request inspections.6 A qualifying owner-builder must personally sign the building-permit application, supervise construction, comply with codes and zoning, and record the required notice with the register of deeds.10 Before occupying a newly created or altered building, obtain Hardeeville’s certificate of occupancy from the Planning Director, Fire Chief and Building Official.21

What should you check before buying land in Hardeeville?

For an individual residential or irrigation well in Hardeeville, a Notice of Intent is required before construction; the individual residential well fee is $70 and the irrigation well fee is $50.11 Confirm utility availability first because available BJWSA services can require connection.5 A qualifying farm structure can receive a state building-code exemption after the required affidavit, but residences are excluded, building-permit authority remains, and FEMA flood standards still apply.22 Ask Building Safety which approvals apply to the proposed farm structure.1 For land outside Hardeeville city limits, consult the Jasper County guide: Jasper County’s zoning ordinance applies to unincorporated land rather than inside Hardeeville.3

Watch-outs

  • Hardeeville’s RA front setback is 100 feet with a table footnote; ask Planning to explain the footnote before placing a home.2313
  • We could not confirm manufactured-home occupancy standards beyond the available provisions; ask Hardeeville Planning which district permits the proposed home.13
  • Owner-builder sale or rental within 2 years after completion creates a presumption that the home was built for sale or rent unless otherwise approved by the commission.10
