Modular home transport is a different animal from hauling a mobile home, and the difference starts in the factory. A modular home is built to the International Building Code — the same standard as a site-built house — and ships to the lot as two, three, or more finished sections rather than a single titled unit on permanent axles. Quartz Transport & Install moves those sections across North Carolina and South Carolina from two hubs: Asheville/Fairview, NC at (828) 888-0327 and Florence/Lydia, SC. Each box still travels as an oversize load on the highway, but the delivery ends with a crane and a foundation, not a set of piers — so the planning, the permits, and the set crew all look different.
Modular vs. manufactured: why the build code changes the move
The cleanest way to understand modular home transport is by what the home is not. A manufactured (mobile) home is built to the federal HUD Code under 24 CFR Part 3280, keeps its steel chassis and axles permanently, and rolls to its lot to sit on a pier-and-anchor system. A modular home is built to state and local code, and most sections are off-frame — they ride to the site on a removable carrier or flatbed and are craned onto a permanent foundation (basement, crawlspace, or slab). That single distinction cascades into everything: how the unit is rigged, how it's taxed, how it's set, and what the new pad has to be. For homes that keep their frame, our single wide mobile home transport and double wide mobile home transport pages cover the pier-and-anchor side of the work.
Oversize permitting for modular sections
Code-built or not, a 14-to-16-foot-wide module is still an oversize load, so it moves under the same state rules as any manufactured-home haul. In North Carolina that means an NCDOT Publication MH-2 mobile and modular home permit — the word "modular" is in the publication name for a reason — setting the legal travel windows, escort counts, and approved routing for each section. NCDOT bars oversize movement in winds above 25 mph and holds wide loads to daylight, off-peak windows, which matters when you're scheduling a crane to meet the trucks. In South Carolina the haul runs under SC Code § 31-17-360 through the county licensing agent. One wrinkle unique to modular: a unit set on a permanent foundation is typically classed as real property, so the county tax-clearance step under NCGS Chapter 105, Article 18 can play out differently than it does for a personal-property mobile home — we confirm the classification before anything ships.
The crane set: marriage wall, bolt-up, and seal
Where a mobile home is rolled into place and tied down, a modular is flown into place. Each section is rigged and lifted by crane onto an engineered foundation, set to a 1/4-inch level tolerance, and then the halves are pulled together at the marriage wall and through-bolted along the floor band, the walls, and the ridge. After the bolt-up the crew weather-seals the mate line, ties the roof sections and ridge together, closes out any site-built dormers or porches that shipped separate, and reconnects plumbing, HVAC, and electrical across the seam. Triple-wide and longer units repeat the pick for each box, which is why a third section usually adds a crane day and another escort to the quote. The leveling, blocking, and connection discipline carries straight over from manufactured work — see mobile home setup for the foundation and connection detail.
Cross-state modular hauls across the Carolinas
Coastal Carolina counties enforce a high-wind design requirement, so a modular bound for the SC Pee Dee or the NC coast needs its foundation and connections detailed for that exposure before the set crew rolls — a brief but non-negotiable line item on those jobs. Most of the value we add, though, is on the cross-state NC↔SC route: a modular built at a plant in the Piedmont and delivered to the Upstate or the WNC mountains crosses both the NCDOT MH-2 framework and SC § 31-17-360 in one move, with a crane waiting at the far end. Carrying licensing on both sides of the line and dispatching from two hubs means one team owns the carrier, the escorts, the crane, and the set — no border hand-off.
