Do you need a building permit in Inman, SC?

Inman requires an application and the required building permit before construction, enlargement, alteration, repair, relocation, demolition or a change of occupancy; regulated electrical, gas, mechanical and plumbing work is also covered.1 Inman directs those applications to SAFEbuilt through the Community Core portal.1

A small project can still need city approval: Inman’s permit page says accessory structures below 200 square feet require application submittal and approval before construction.1 Inman adopts building and related technical codes when adopted by the South Carolina Building Code Council, so a building-permit exemption should not be treated as permission to ignore applicable construction standards.8

Who handles Inman building permits and zoning approval?

Start an Inman construction project with City Hall and a consultation with the Planning Director, as the city’s planning page instructs.2 Inman’s Planning Director implements the city zoning ordinance and issues administrative approvals for construction and renovation, including work needing a building permit.2 Building-permit applications go to SAFEbuilt through Community Core, and Inman says a development permit must be on file in Planning before applying for building permits.1

Ask Inman Planning for the current project-specific review sequence, building-permit fee schedule and inspection requirements before submitting plans.2 Septic application questions belong with SCDES rather than the city zoning counter.39

Does Inman have zoning, and what about RVs and tiny homes?

Land inside Inman city limits is subject to city zoning, planning and land-development ordinances, and the Planning Director implements the zoning ordinance.52 Ask Inman Planning to identify the parcel’s current district, permitted residential uses, minimum lot size, setbacks and any minimum dwelling size before choosing a house design.2

We could not confirm Inman’s rules for living in an RV, occupying a tiny home, placing a manufactured home or adding an accessory dwelling; ask Inman Planning about the exact proposed use and parcel.2 The city’s development review distinguishes single-family development plats handled by staff from apartment site plans, town home plats, mixed-use developments and planned developments reviewed by the Planning Commission.2

How do septic permits work inside Inman?

An Inman home or manufactured home on land without public or community sewer needs SCDES approval and a septic installation permit first.6 The septic application fee is $150, and a Permit to Construct is valid for 5 years; renewal or modification requires a new application and another fee.6 Direct application questions before submission to SCDES Onsite Wastewater Customer Support; the Greenville/Spartanburg regional office covers Spartanburg County.910

Spartanburg County’s soils rated not limited for conventional septic drain fields cover 60.5% of the county, but that countywide figure cannot establish suitability for an Inman lot: plan for a site evaluation rather than assuming a standard drain field will work.11

Can you build your own home or use off-grid sanitation in Inman?

South Carolina’s owner-builder exemption can apply to an Inman residence intended for the owner or family, with personal supervision, the required building-permit signature and a recorded public notice; construction must still comply with applicable laws, building codes and zoning.7 Selling or renting within 2 years after completion creates a statutory presumption against that exemption unless otherwise approved by the commission.7 Certain owner-performed residential improvements have a separate state exemption from building-permit and licensing requirements; confirm that the proposed work qualifies before relying on it.12

South Carolina may consider permitted composting or incinerating toilet systems on unsuitable septic sites, subject to engineering and agency approvals; a pressurized-water structure generating graywater also needs an approved graywater wastewater system.1314

What steps should you take before building a home in Inman?

Begin with Inman Planning: request the parcel’s zoning requirements and a consultation before starting the construction project.2 Establish whether the proposed home has public or community sewer; if not, obtain SCDES site approval and a septic installation permit before construction.6 Secure the city development approval required before the building-permit application, then apply to SAFEbuilt through Community Core for the building permit.1

Ask Inman Planning to confirm floodplain review, private-well requirements and the final occupancy process for the parcel, which we could not confirm.2 Inman’s permit page requires approval before sidewalk or driveway installation; a driveway opening onto a non-controlled-access highway in the state primary system also requires a Department of Transportation driveway permit.115

Watch-outs

  • Inman’s small-accessory-building exemption still requires application submittal and approval before construction.1
  • We could not confirm permission to live in an RV or tiny home in Inman; obtain an answer from Inman Planning for the proposed parcel and use.2
  • South Carolina’s 2024 mandatory codes have a local implementation date of January 1, 2027; ask Inman’s building official which edition governs a project spanning that date.16
  • A qualifying farm-structure code exemption excludes residences and attached structures and does not remove municipal authority to issue building permits.17
