Most Union County sets we run are park-to-land relocations — a family pulls a home off a rented lot and lands it on private ground of their own — and in South Carolina that move can't legally finish until the county signs off on it. That's why mobile home setup in Union County, SC begins on paper: the permit and the inspection are what convert a hauled box on temporary blocks into a level, anchored, code-compliant home the county will let you occupy. The seat is Union, set in the upper Piedmont between Spartanburg and the Broad and Tyger rivers, with Jonesville, Lockhart, Carlisle, and Buffalo scattered through rolling farm and timber country and US 176 heading northwest to the Spartanburg Upstate. Mobile Home Mover Pro carries the whole thing — the haul and the set — as one unbroken job, so the crew that delivers the home also positions, blocks, levels, and ties it down, with no seam for details to slip through. This is no referral desk; book a Union County set and our own crew arrives.
Permitting and inspecting a Union County set
In South Carolina a set is a permitted, inspected job rather than a handshake, and Union County's paperwork trips up more owners than anything else on a relocation — so we carry it for you. Getting the home to the new land requires an SCDOT oversize/overweight movement permit, and the county issues a tax-paid moving permit under S.C. Code § 31-17-360 only after the treasurer certifies the property taxes are current. The set draws its own permit and inspection through the county's Building Safety & Floodplain Management office (gearupunionsc.com) at the county complex in Union — and with no online permit portal here, that application moves the old-fashioned way, on paper or PDF, in person, by mail, or by phone, which makes permit turnaround the longest single lever in the whole schedule. Once the home is blocked, leveled, and anchored, a local building inspector checks pier spacing, leveling, anchoring, and utility connections against the manufacturer's installation manual and the federal install rule HUD 24 CFR 3285 before a certificate of occupancy is issued. We open the county application the day you book, pull the permit, and stand with the inspector so the set clears on the first pass.

Building the pier system and leveling the chassis
The physical work begins under the floor. A manufactured home rests on two or more steel I-beams, and each beam has to land on a pier system that carries the house's full weight down into firm bearing. Piers stack from 8x16-inch concrete block on a poured or precast footing pad, sized so the soil never overloads — footing sizing that matters most on the soft river-bottom parcels by the Broad or Tyger, where an undersized pad sinks and the home settles crooked inside a year. Under each I-beam the piers follow the spacing the home's manufacturer installation manual sets, typically every 8 to 10 feet, with extra piers along the marriage line, under wide wall openings, and beneath heavy point loads. With the piers stacked, the home gets leveled using hardwood shim plates and wedge pairs until the chassis reads true to about 1/4 inch end to end, confirmed with a long level and a laser line rather than a naked eye. A frame left out of level racks the whole structure — doors quit latching, windows bind, drywall seams open — so a park home relocated onto a wooded Carlisle lot with patchy bearing earns the same dead-level finish as one on an open city lot. Our mobile home leveling page details that precision step.
Joining the halves and buttoning up the connections
A double-wide adds one operation the single-wide never needs: mating the sections. Each half travels and permits on its own, then gets pulled together at the pad and locked along the marriage line — the centerline where floors, walls, and roof of both halves lag and bolt into one structure. The crew closes it with lag bolts on the manufacturer's schedule, mates the ridge beam, and seals the seam with gasket and roof flashing so it stays watertight. With the home level and joined, the crew finishes the skirting to enclose the crawl space and ties in the utility stub-outs — power, water, septic, and gas — then squares the set against the manufacturer's installation manual for inspection. That extra section, extra blocking, and extra seal are why a double-wide set runs $3,000–$6,000 against a single-wide's $1,500–$3,000. Skirting and crawl-space closure get their own walkthrough on our mobile home skirting page.
Tying the home down for Wind Zone I
Leveling supports the home; anchoring stops it from sliding or lifting in a storm, and the federal standard sizes that job to your location. Union County is HUD Wind Zone I — the baseline inland tier rated for roughly 70-mph design wind, like the rest of the upper SC Piedmont. Per HUD 24 CFR 3280 Subpart G, a Zone I home ties to its chassis with auger ground anchors and frame-tie straps on the manufacturer's schedule — a lighter count and lighter strapping than the over-the-top systems a coastal Zone II county like Horry or Charleston demands. On a Union set the ground drives the work, not the wind: a soft river-bottom parcel by the Broad or Tyger, or a wooded rural lot with uneven bearing, may need deeper or engineered anchors to reach firm holding. We match the home's data-plate Wind Zone to the parcel before the first anchor goes down; the full tie-down spec lives on our mobile home anchoring page.
One crew, one number, from land to lived-in
The edge in Union County is that a relocation and the set behind it are a single job. Quote transport and set together and the same crew that delivers the home positions it, builds the pier system, brings it dead-level to a quarter inch, bolts up the marriage line on a double-wide, anchors it for Wind Zone I, closes the skirting, and meets the Union building inspector — one mobilization, one number, with no seam between hauler and set crew for a detail to fall through. Setup grounds our upper-Piedmont coverage across South Carolina, alongside the statewide mobile home setup service. Bringing a sound home onto Union County land is the job of our Union County mobile home movers; when a home is beyond rescue, we also run mobile home demolition and mobile home removal in Union County.
