Summary

Dorchester County Building Services issues the building permit for every residential pool, spa, and permanent hot tub in the unincorporated county. The pool is built to South Carolina's adopted 2021 codes, and the electrical must be done by a SC-licensed contractor.

These county ordinances apply to unincorporated areas of Dorchester County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The construction sites for in-ground swimming pools and spas shall be provided with construction fencing to surround the site from the time that any excavation occurs up to the time that the permanent barrier is completed. The fencing shall be not less than 4 feet in height [ISPSC 305.1.1].

Full Breakdown

Before a pool is dug in unincorporated Dorchester County, the Building Services Department on North Main Street in Summerville issues a building permit and reviews setbacks, drainage, electrical, and the barrier. South Carolina enforces the International Swimming Pool and Spa Code, so the pool is built to its barrier and equipment rules, and an in-ground pool site must be fenced at least 4 feet high during construction. Public and semi-public pools follow a separate track under SCDES Regulation 61-51. Towns such as Summerville issue their own pool permits inside town limits.

Violations & Fines

Building a pool without the Dorchester County permit is illegal construction, subject to a stop-work order and penalty fees. Skipping the barrier or electrical inspection stops the pool from passing final approval.

Frequently Asked Questions

Do I need a permit for a backyard pool?
Yes. Dorchester County Building Services requires a building permit before construction for in-ground and most above-ground pools, with setback, barrier, and electrical inspections.
What about public or neighborhood pools?
Public and semi-public pools are permitted and inspected by South Carolina DES under Regulation 61-51, a separate process from the county residential pool permit.
