Columbia does not impose general municipal impact fees on residential ADUs. New connections to Columbia Water trigger water and sewer tap fees and capacity charges. Any local impact fee in South Carolina must comply with the strict procedural rules of the SC Development Impact Fee Act (SC Code §6-1-910 to §6-1-2010), which requires a capital improvements plan, public hearings, and a rational nexus between the fee and the service. Standard zoning and building permit fees from Columbia's fee schedule apply.
Under the South Carolina Development Impact Fee Act (SC Code §6-1-910 to §6-1-2010), a municipality may impose impact fees only after adopting a capital improvements plan, holding public hearings, and demonstrating a rational nexus between the fee and the cost of new public facilities. Columbia has not adopted a general transportation, parks, or school impact fee on residential ADUs. Columbia Water charges water and sewer tap fees and capacity charges for new service connections; an ADU that uses the primary residence's existing water and sewer service may avoid a new tap fee, while an ADU requiring its own meter or upsized service will incur charges. Stormwater utility billing under Columbia's stormwater management program may also apply. Standard zoning permit, building permit, and trade permit fees from Columbia Planning and Development apply at the time of building permit issuance. Richland County also charges fees for utility services to ADUs in unincorporated parts of the metro area; within Columbia city limits, city fees apply.
Failure to pay required water/sewer tap fees or building permit fees blocks permit issuance and final inspection. Unpaid Columbia Water connection charges may become a lien on the property. Disputes over impact fees imposed under §6-1-2010 follow the statutory appeal process in the SC Development Impact Fee Act. Confirm current fee amounts with Columbia Planning and Development and Columbia Water.
