Charleston records 1,977 annual heating degree days against 2,304 cooling in the NOAA 1991–2020 normals. Cooling load exceeds heating by 17%. Every other market covered here is heating-led or close to balanced, and the demand calendar shifts accordingly.

The housing profile inverts the usual pattern too. On ACS 2020–2024 five-year estimates the city of Charleston records median household income of $92,414 against the metro's $85,254. In most metros the city is the poorer half. Here it is the richer one.

The city is still the thinner owner-occupier pool: 55.6% owner-occupancy and 47.7% single-family detached, against 69.1% and 61.7% across the Berkeley, Charleston and Dorchester metro. High-value work concentrates in the city; volume sits outside it.

Charleston established the first preservation ordinance in the United States in 1931, and the Board of Architectural Review it created is still the gate. Its stated scope is all exterior work visible from any public right of way, covering new construction, alterations and renovations.

That reaches straight into trade work. The City's own permit guidance lists BAR review as a step for Residential re-roofing and for window and door replacement where the property sits within the designated purview. Fences, walls and site work have their own submittal packet.

The scheduling consequence is the part to price. The boards meet on the second and fourth Wednesday and Thursday of the month, with applications due around ten days ahead. A roof quoted as a two-week job can carry a month of review in front of it, and a contractor who has not built that into the timeline will be explaining it to the customer rather than to the board.

From 1 July 2020 all new residential and non-residential construction in the Special Flood Hazard Area must be designed two feet above base flood elevation. A residential substantial improvement carries a one foot requirement. For projects applied for on or after 1 January 2024, slab-on-grade building diagrams are prohibited in the flood hazard area.

That converts the fifty per cent substantial-improvement test from paperwork into a scope change. A large Charleston remodel that crosses the line brings an elevation requirement with it, and remodelers price this wrong more often than any other item on the page.

The water is not hypothetical. NOAA's Charleston tide gauge recorded 21 high-tide flood days in 2023, 14 in each of 2019 and 2020, and 12 in 2022. Storm records tell less than people assume: 580 of the 751 Charleston County storm rows across 2015 to 2024 have an empty property damage field, so those totals are a floor rather than a measure, and we will not present them as more.

South Carolina splits residential work across two boards. Under Title 40 Chapter 59 a Residential Builder licence is required above $5,000, and a Residential Specialty registration above $500 for ten named trades including roofing. Under Chapter 11 a general or mechanical licence is required above $10,000, a threshold raised from $5,000 in 2023, and that is where HVAC, plumbing and electrical sit.

Fencing appears in neither list. It is absent from the specialty classifications and from the Chapter 11 classifications, so no South Carolina licence or registration applies unless the work is itself a residential structure above $5,000.

One change worth diarising: from 1 July 2026 Charleston County folds its sub-trade permits, roofing among them, into a single main building permit, with a new revision fee and a higher reinspection fee.
