Mobile home setup in Horry County, SC is the work that turns a hauled box on temporary blocks into a level, anchored, code-compliant dwelling — and on the Grand Strand it carries one extra demand the inland counties don't: a coastal wind standard. The county seat is Conway, sitting inland on the Waccamaw River, with the population spreading east to Myrtle Beach and the 60-mile beachfront and north through Loris and Longs toward the North Carolina line. That flat, sandy coastal plain is easy to haul across but unforgiving to set on: soft soil that won't carry a careless footing, and a HUD Wind Zone II requirement that scales up the anchoring. Mobile Home Mover Pro runs the haul and the set as one continuous job, so the same crew that brings the home positions it, blocks it, levels it, bolts it up, and ties it down — without a hand-off where details get dropped.
What a Horry County setup costs
A standard set on a prepared pad runs about $1,500–$3,000 for a single-wide and $3,000–$6,000 for a double-wide in Horry County, with the double-wide's marriage-line bolt-up and second-section seal driving the higher number. That figure assumes a graded, drained pad that's ready to bear load. Two coastal factors push a Horry set toward the top of the band. The HUD Wind Zone II anchoring package is heavier than the inland upcountry — more auger anchors, heavier frame ties, and over-the-top straps — which adds hardware and labor. And the soft, saturated coastal-plain soil around Conway and the river bottoms often needs an oversized footing pad or a poured runner footing so the piers don't settle. When the set is quoted alongside the haul on a Horry County move, it lands cheaper than a separate set crew, because the toter, blocking, and anchoring all run in one mobilization.

Pier blocking and leveling to a quarter inch — on coastal soil
Setup starts under the floor. A manufactured home rides on two or more steel I-beams, and those beams have to land on a pier system that transfers the whole weight of the house into solid bearing. Crews build piers from stacked 8x16-inch concrete block on a poured or precast footing pad, sized so the soil isn't overloaded — and that sizing matters more in Horry than almost anywhere inland, because the sandy, water-table-high ground of the coastal plain punches an undersized footing into the dirt and lets the home settle unevenly within a year. Piers go under each I-beam at the spacing the home's manufacturer installation manual specifies, usually every 8 to 10 feet, with added piers at the marriage line, under wide wall openings, and beneath heavy point loads. Then the home gets leveled — the precision step. Using hardwood shim plates and wedge pairs on each pier, the crew brings the chassis true to within roughly 1/4 inch across its full length, checked with a long level and a water or laser line, not by eye. A frame out of level by even half an inch racks the structure: doors won't latch, windows bind, and drywall seams crack. Set it dead-level on day one and it stays true for years; set it sloppy and it needs a re-level call before the first winter.
HUD Wind Zone II anchoring: tie-downs rated to the Grand Strand
Leveling holds the home up; anchoring keeps it from moving sideways or lifting in a storm — and the federal standard scales the requirement to your geography. Under HUD 24 CFR 3280, Subpart G, every manufactured home is built and must be anchored to a designated Wind Zone. The inland SC upcountry and Midlands are Wind Zone I, engineered to resist roughly 70-mph design wind. Coastal Horry County is Wind Zone II, built and anchored to roughly 100-mph design wind. The practical difference is in the hardware: a Zone I inland set uses fewer ground anchors and lighter strapping, while a Zone II coastal set demands more frequent auger anchors, heavier frame-tie straps to the chassis, and over-the-top straps that pass across the roof to resist overturning. A home built to Zone II that's anchored as if it were Zone I is not legally set, and it won't survive a named storm on the Strand. We verify the home's data-plate Wind Zone against Horry County before a single anchor goes in — the full tie-down spec lives on our mobile home anchoring page, and the precision-leveling detail on our mobile home leveling page.
The Conway permit and the inspector's setup check
A set in Horry County is a permitted, inspected operation — gated through the tax office, the way all of South Carolina runs it. The home travels under a county moving permit issued under S.C. Code § 31-17-360, which the licensing agent won't release until the Horry County treasurer certifies the home's property taxes are paid and current. The set itself is filed through Horry County Code Enforcement, and unlike the many SC counties still on paper, Horry publishes a queryable record. The Horry County permit portal shows more than 169 manufactured-home permits on record across 2024–2026 — filed by 33 distinct licensed installers and movers, with Conway, Loris, Longs, Myrtle Beach, and Galivants Ferry the towns that show up most. Because we read that history before we quote, we already know how the county codes a set and what it expects at inspection. Once the home is blocked, leveled, and anchored, a local building inspector verifies pier spacing, leveling, anchoring, and utility connections against the manufacturer's installation manual before a certificate of occupancy is issued. Mobile Home Mover Pro pulls the permit, clears the treasurer's tax certificate, and meets the inspector — that's part of what you're buying.

Marriage-line bolt-up, skirting, and utility hookups
For a double-wide, the set has one more critical operation single-wides skip: joining the sections. Each half ships and permits separately, then gets drawn together at the pad and locked along the marriage line — the centerline where the floors, walls, and roof of the two halves bolt and lag into a single structure. Crews close it with lag bolts on the manufacturer's schedule, mate the ridge beam, and seal the seam with gasket and roof flashing so the joint never leaks, which counts double in the rain-heavy Grand Strand climate. With the home level, joined, and anchored to Wind Zone II, the crew runs the utility hookups — power, water, and sewer or septic stub-outs — and installs the skirting to close the crawl space against coastal wind and moisture. Storms are the steady driver of this work in Horry: with 34 federal disaster declarations on record, the tear-down-and-replace cycle is constant, and a totaled home means a new one delivered, set, and anchored to stand up to the next system.
