Mobile Home Leveling Questions, Answered Straight

Singlewides are $450 to $800 and doublewides $750 to $1,400. Piers that need resetting inside that work are $75 to $150 each and piers that have to be rebuilt entirely are $150 to $400 each, and each should be quoted individually before anything proceeds. The survey costs nothing, and the price should be in writing before a jack goes under the frame.

It is a length of tube filled with water. Water finds the same height at both ends, so from one fixed reference point it reads true elevation at every pier on the home, with no batteries and nothing to calibrate. It is how the crew produces a number for each pier instead of an impression. If whoever is quoting your job has not shot the piers with a water level or a rotary laser, they are naming a price for work they have not measured.

Doors that will not latch, windows binding in their tracks, a slope you feel walking down the hallway, cracks opening where walls meet ceilings, skirting bowing outward with nothing having hit it, and on a doublewide a seam opening along the center of the ceiling. The marble test still works: if it rolls on its own, piers have moved.

Every three to five years is the normal cycle on Lowcountry ground, and it is a maintenance interval rather than a repair you do once. The reason is the water table. Soil under a pier footing here is saturated for a good part of the year, and saturated ground moves under concentrated load. Homes on high, well-drained, properly prepared pads get the long end of that range. Homes on low ground get the short end.

You should not, and not only because South Carolina licenses this trade. A manufactured home is fifteen thousand pounds and up, and a lift is done in small increments at multiple stations with the load carried on cribbing, never on hydraulics. Doing it at one point with one jack racks the frame, which is what cracks drywall and pops trim, and being under a home held by a jack is how people are killed. The tools also matter: without a survey you do not know which piers are low.

Three to five hours for a singlewide and six to eight for a doublewide. Almost every job is finished in a single day and you can stay in the home while it happens. Very low clearance, standing water underneath, or a home needing several piers rebuilt can push into a second day, and that should be flagged at the survey rather than discovered mid-job.

Yes, and the statute is specific. Section 40-29-30(A) states that no manufactured home installer may install manufactured housing without being licensed by the Manufactured Housing Board, and section 40-29-20(8) defines installing as the operations that render a home fit for habitation, listing positioning, blocking, leveling, supporting, tying down, and connecting utilities. The South Carolina Building Codes Council has put out a notice to building officials saying the same. Releveling is licensed work, not handyman work. Licensees post a $5,000 bond and renew every two years.

Placing or setting a manufactured home does require one. Charleston County's flood ordinance states plainly that permits shall be obtained for the placement of manufactured homes, and the county's fee schedule lists a $100 manufactured housing permit for setup on a new or existing site. Berkeley County charges a $45 setup fee plus a $25 administrative fee and a $5 decal. Whether a standalone relevel of a home already sitting where it sits triggers a county permit is not something we will state for you, because the counties do not publish a clear answer; call Charleston County Building Services and confirm. State law is clear on the other half of it: leveling is licensed installer work regardless. Where a permit is required it has to be pulled, and state law caps a local installation inspection fee at $100.

State law requires a moving permit before the home is relocated. To issue it the county needs a certificate from the county treasurer confirming no taxes are owed on the home, along with the title or the title application. At the far end, the receiving county issues a setup permit and inspects the blocking, anchoring, and utility connections before the home can be occupied. That paperwork belongs inside a proper transport-and-setup job, so confirm it is on the quote.

Published 2026 national cost guides put a full-service local move at roughly $5,000 to $8,000 for a singlewide and $8,000 to $15,000 for a doublewide, with transport on its own starting around $1,000 to $5,000. Locally the number is driven by distance and route, how much pad preparation the new ground needs, the anchor count, permits and escorts, and whether decks and add-ons are coming along. Ask for any setup quote to be itemized after a site visit.

Because of the pad, not the home. Fresh footings set on ground that was never graded or compacted consolidate hard through their first two or three wet seasons, and they do it unevenly, so the whole home goes out of plane at once. It is the most common cause of a badly settled home in this area that is only a few years old on its lot. Correcting the pier work is routine, but unless the pad problem is addressed it will recur.

The federal standard at 24 CFR 3280.305(c)(2)(ii) names Beaufort, Berkeley, Charleston, Colleton, Dorchester, Georgetown, Horry, Jasper, and Williamsburg as South Carolina's Wind Zone II counties. Every other county in the state is Zone I. Zone II is designed to a 100 mph wind with anchorage loads of 39 pounds per square foot of horizontal drag and 27 of uplift. On counts, a new home follows its manufacturer's instructions or 24 CFR Part 3285. A used home without instructions follows the Zone II table in SC Regulation 79-42, which runs from 2 vertical and 4 diagonal ties on a single-section home up to 46 feet to 4 and 7 at 73 to 84 feet, with multi-section homes needing diagonal ties only. A retrofit is $600 to $3,500.

Mechanically, they have to be. Straps were tensioned against the home at whatever height it sat when they were installed, so every fraction of an inch the home drops becomes slack somewhere in the system, and a slack strap contributes close to nothing under load. That is why re-tensioning belongs in every relevel rather than being sold as an add-on.

Before June if you can. Atlantic hurricane season runs the first of June through the end of November, pre-season inspections book heavily through late spring, and after any named storm brushes the area the schedule fills with post-storm checks for weeks. Winter and early spring are the easy time to get a retrofit scheduled, and if a relevel is also due, one visit handles both.

It matters more here than almost anywhere. That is the vapor barrier, and it is the only thing between damp ground and your insulation and subfloor. On a shallow water table, an open belly loads moisture into your floor system for most of the year, and the sequence from damp insulation to soft subfloor to joist rot is depressingly reliable. Patches are $300 to $800 and full replacement $1,200 to $4,500, which is cheap against replacing a floor.

Almost certainly. Park management, lenders, and insurers in this area all have reasons to want proof that a home is level, properly supported, and anchored before a sale goes through, and financed purchases often need foundation documentation on top. A settled chassis and a short anchor system are the two most expensive surprises in a used manufactured home. The pre-sale survey is $150 to $350 with a written report, and we can often credit the fee toward anything it finds, so ask.

Four things. A South Carolina license you can verify through the LLR Manufactured Housing Board. Proof of insurance. A real pier-by-pier survey with a water level or laser before any price is named. And per-pier numbers in writing rather than one lump figure. Treat a promise of a permanent relevel as disqualifying: on this ground it is not a thing that exists, and somebody willing to say it is telling you how the rest of their work goes.

For a routine relevel of a home already sitting where it sits, no. For placing, replacing, or moving a home it changes a great deal. Charleston County's flood ordinance sets the design flood elevation at the base flood elevation plus two feet of freeboard, requires manufactured homes in A and AE zones to have their frames elevated on a permanent foundation designed by a South Carolina registered engineer and approved by the building official, and states that new or replacement manufactured homes shall not be placed in VE or Coastal A zones at all. An elevation certificate from a surveyor or engineer gates the final inspection. Berkeley County uses the same two-foot freeboard and will not release power without the certificate.
