The Charleston Lowcountry and York County on the South Carolina side of the Charlotte metro, across Berkeley, Charleston, Dorchester, Lancaster and York counties. Each town below has its own permit authority and its own housing stock, and both change what the work involves.
Fences, deck repair and the materials that survive a Lowcountry summer.

Deck and fence failures here start at ground level and at connections, not in the middle of a board. Posts rot at the soil line where nobody looks, and decks come away from the house at the ledger rather than breaking underfoot.
New decks, screened porches and outdoor living are covered on the main site; this division is repair, fencing and the material decisions that come with both.
The design conditions the City of Charleston publishes for the current South Carolina building codes explain a great deal about outdoor structures here: a design wind speed of 150 miles per hour, seismic design category D2, a frost-line depth of zero inches and a termite hazard classified as very heavy. Read together, that means a footing on the coast is not sized against frost — it is sized for bearing and for uplift. It also means untreated timber touching the ground is a short-term decision.
The York County towns are inland and their published criteria are not Charleston's, so the balance shifts there. What does not change is where these structures fail. Deck collapses are overwhelmingly ledger failures — the wrong fasteners, or no flashing behind the ledger, letting water into the rim joist of the house itself. Fences go at the post at the soil line, and how the post was set decided that years in advance.
Whether a particular deck needs a building permit — and whether a freestanding one is exempt — is set by the local building department rather than by a statewide rule, so it is confirmed for the address before work is scheduled.
Between them, the towns above fall under 12 separate permit authorities.
In the Lowcountry, permits come from the City of Charleston for Charleston, the Town of Mount Pleasant for Mount Pleasant, the City of North Charleston for North Charleston, the Town of Summerville for Summerville, the City of Goose Creek for Goose Creek, the Town of Moncks Corner for Moncks Corner and Charleston County for Johns Island.
In York and Lancaster counties, from the City of Rock Hill for Rock Hill, the Town of Fort Mill for Fort Mill, the Town of Clover for Clover, the City of York for York and Lancaster County for Indian Land.
Deck permit thresholds and fence rules are both set locally, so two addresses a mile apart can genuinely have different answers.
Fences more often need a zoning or an association approval than a building permit. In the newer subdivisions in Fort Mill, Indian Land and Rock Hill that approval is a real schedule item, and it governs height, material and which side the finished face goes on.
It is the wrong question on the coast, where the frost-line depth is zero. Footings here are sized for bearing and uplift, and soft or saturated ground needs more of both.
More often it needs a zoning or association approval than a building permit, and the rules differ by town and by neighbourhood.
Height, material and which side the finished face faces are usually decided there rather than by the building code.
The ledger — the connection to the house — first, and then the posts at the soil line.
Those two account for the overwhelming majority of failures, in both markets and at any age of structure.
